Get Started
This topic provides overviews of NetQ components, architecture, and the CLI and UI interfaces. These provide the basis for understanding and following the instructions contained in the rest of the user guide.
Cumulus NetQ Overview
Cumulus® NetQ is a highly-scalable, modern network operations tool set
that provides visibility and troubleshooting of your overlay and
underlay networks in real-time. NetQ delivers actionable insights and
operational intelligence about the health of your data center - from the
container, virtual machine, or host, all the way to the switch and port.
NetQ correlates configuration and operational status, and instantly
identifies and tracks state changes while simplifying management for the
entire Linux-based data center. With NetQ, network operations change
from a manual, reactive, box-by-box approach to an automated, informed
and agile one.
Cumulus NetQ performs three primary
functions:
Data collection: real-time and historical telemetry and network
state information
Data analytics: deep processing of the data
Data visualization: rich graphical user interface (GUI) for
actionable insight
NetQ is available as an on-site or in-cloud deployment.
Unlike other network operations tools, NetQ delivers significant
operational improvements to your network
management and maintenance processes. It simplifies the data center
network by reducing the complexity through real-time visibility into
hardware and software status and eliminating the guesswork associated
with investigating issues through the analysis and presentation of
detailed, focused data.
Demystify Overlay Networks
While overlay networks provide significant advantages in network
management, it can be difficult to troubleshoot issues that occur in the
overlay one box at a time. You are unable to correlate what events
(configuration changes, power outages, etc.) may have caused problems in
the network and when they occurred. Only a sampling of data is available
to use for your analysis. By contrast, with Cumulus NetQ deployed, you
have a networkwide view of the overlay network, can correlate events
with what is happening now or in the past, and have real-time data to
fill out the complete picture of your network health and operation.
In summary:
Without NetQ
With NetQ
Difficult to debug overlay network
View networkwide status of overlay network
Hard to find out what happened in the past
View historical activity with time-machine view
Periodically sampled data
Real-time collection of telemetry data for a more complete data set
Protect Network Integrity with NetQ Validation
Network configuration changes can cause numerous trouble tickets because
you are not able to test a new configuration before deploying it. When
the tickets start pouring in, you are stuck with a large amount of data
that is collected and stored in multiple tools making correlation of the
events to the resolution required difficult at best. Isolating faults in
the past is challenging. By contract, with Cumulus NetQ deployed, you
can proactively verify a configuration change as inconsistencies and
misconfigurations can be caught prior to deployment. And historical data
is readily available to correlate past events with current issues.
In summary:
Without NetQ
With NetQ
Reactive to trouble tickets
Catch inconsistencies and misconfigurations prior to deployment with integrity checks/validation
Large amount of data and multiple tools to
correlate the logs/events with the issues
Correlate network status, all in one place
Periodically sampled data
Readily available historical data for viewing and correlating changes in the past with current issues
Troubleshoot Issues Across the Network
Troubleshooting networks is challenging in the best of times, but trying
to do so manually, one box at a time, and digging through a series of
long and ugly logs make the job harder than it needs to be. Cumulus NetQ
provides rolled up and correlated network status on a regular basis,
enabling you to get down to the root of the problem quickly, whether it
occurred recently or over a week ago. The graphical user interface makes
this possible visually to speed the analysis.
In summary:
Without NetQ
With NetQ
Large amount of data and multiple tools to
correlate the logs/events with the issues
Rolled up and correlated network status, view events and status together
Past events are lost
Historical data gathered and stored for comparison with current network state
Manual, box-by-box troubleshooting
View issues on all devices all at once, pointing to the source of the problem
Track Connectivity with NetQ Trace
Conventional trace only traverses the data path looking for problems,
and does so on a node to node basis. For paths with a small number of
hops that might be fine, but in larger networks, it can become extremely
time consuming. With Cumulus NetQ both the data and control paths are
verified providing additional information. It discovers
misconfigurations along all of the hops in one go, speeding the time to
resolution.
In summary:
Without NetQ
With NetQ
Trace covers only data path; hard to check control path
Both data and control paths are verified
View portion of entire path
View all paths between devices all at once to find problem paths
Node-to-node check on misconfigurations
View any misconfigurations along all hops from source to destination
Cumulus NetQ Components
Cumulus NetQ contains the following applications and key components:
Telemetry data collection and aggregation
NetQ switch agents
NetQ host agents
Telemetry data aggregation
Database
Data streaming
Network services
User interfaces
While these function apply to both the on-site and in-cloud solutions, where
the functions reside varies, as shown here.
NetQ interfaces with event notification applications, third-party
analytics tools.
Each of the NetQ components used to gather, store and process data about
the network state are described here.
NetQ Agents
NetQ Agents are software installed and running on every monitored node
in the network - including Cumulus® Linux® switches, Linux bare-metal
hosts, and virtual machines. The NetQ Agents push network data regularly
and event information immediately to the NetQ Platform.
Switch Agents
The NetQ Agents running on Cumulus Linux switches gather the following
network data via Netlink:
Interfaces
IP addresses (v4 and v6)
IP routes (v4 and v6)
Links
Bridge FDB (MAC Address table)
ARP Entries/Neighbors (IPv4 and IPv6)
for the following protocols:
Bridging protocols: LLDP, STP, MLAG
Routing protocols: BGP, OSPF
Network virtualization: EVPN, VXLAN
The NetQ Agent is supported on Cumulus Linux 3.3.2 and later.
Host Agents
The NetQ Agents running on hosts gather the same information as that for
switches, plus the following network data:
Network IP and MAC addresses
Container IP and MAC addresses
The NetQ Agent obtains container
information by listening to the Kubernetes orchestration tool.
The NetQ Agent is supported on hosts running Ubuntu 16.04, Red Hat®
Enterprise Linux 7, and CentOS 7 Operating Systems.
NetQ Core
The NetQ core performs the data collection, storage, and processing
for delivery to various user interfaces. It is comprised of a collection
of scalable components running entirely within a single server. The NetQ
software queries this server, rather than individual devices enabling
greater scalability of the system. Each of these components is described
briefly here.
Data Aggregation
The data aggregation component collects data coming from all of the NetQ
Agents. It then filters, compresses, and forwards the data to the
streaming component. The server monitors for missing messages and also
monitors the NetQ Agents themselves, providing alarms when appropriate.
In addition to the telemetry data collected from the NetQ Agents, the
aggregation component collects information from the switches and hosts,
such as vendor, model, version, and basic operational state.
Data Stores
Two types of data stores are used in the NetQ product. The first stores
the raw data, data aggregations, and discrete events needed for quick
response to data requests. The second stores data based on correlations,
transformations and processing of the raw data.
Real-time Streaming
The streaming component processes the incoming raw data from the
aggregation server in real time. It reads the metrics and stores them as
a time series, and triggers alarms based on anomaly detection,
thresholds, and events.
Network Services
The network services component monitors protocols and services operation
individually and on a networkwide basis and stores status details.
User Interfaces
NetQ data is available through several
user interfaces:
NetQ CLI (command line interface)
NetQ UI (graphical user interface)
NetQ RESTful API (representational state transfer application programming interface)
The CLI and UI query the RESTful API for
the data to present. Standard integrations can be configured to
integrate with third-party notification tools.
Data Center Network Deployments
There are three deployment types that are commonly deployed for network management in the data center:
Out-of-Band Management (recommended)
In-band Management
High Availability
A summary of each type is provided here.
Cumulus NetQ operates over layer 3, and can be used in both layer 2 bridged and
layer 3 routed environments. Cumulus Networks always recommends layer 3
routed environments whenever possible.
Out-of-band Management Deployment
Cumulus Networks recommends deploying NetQ on an out-of-band (OOB)
management network to separate network management traffic from standard
network data traffic, but it is not required. This figure shows a sample
CLOS-based network fabric design for a data center using an OOB
management network overlaid on top, where NetQ is deployed.
The physical network hardware includes:
Spine switches: where data is aggregated and distributed ; also known as an aggregation switch, end-of-row (EOR) switch or distribution switch
Leaf switches: where servers connect to the network; also known as a Top of Rack (TOR) or access switch
Server hosts: where applications are hosted and data served to the user through the network
Exit switch: where connections to outside the data center occur; also known as Border Leaf or Service Leaf
Edge server (optional): where the firewall is the demarcation point, peering may occur through the exit switch layer to Internet (PE) devices
Internet device (PE): where provider edge (PE) equipment communicates at layer 3 with the network fabric
The diagram shows physical connections (in the form of grey lines)
between Spine 01 and four Leaf devices and two Exit devices, and Spine
02 and the same four Leaf devices and two Exit devices. Leaf 01 and Leaf
02 are connected to each other over a peerlink and act as an MLAG pair
for Server 01 and Server 02. Leaf 03 and Leaf 04 are connected to each
other over a peerlink and act as an MLAG pair for Server 03 and Server
04. The Edge is connected to both Exit devices, and the Internet node is
connected to Exit 01.
Data Center Network Example
The physical management hardware includes:
OOB Mgmt Switch: aggregation switch that connects to all of the network devices through communications with the NetQ Agent on each node
NetQ Platform: hosts the telemetry software, database and user interfaces (refer to description above)
These switches are connected to each of the physical network devices
through a virtual network overlay, shown with purple lines.
In-band Management Deployment
While not the preferred deployment method, you might choose to implement
NetQ within your data network. In this scenario, there is no overlay and
all traffic to and from the NetQ Agents and the NetQ Platform traverses
the data paths along with your regular network traffic. The roles of the
switches in the CLOS network are the same, except that the NetQ Platform
performs the aggregation function that the OOB management switch
performed. If your network goes down, you might not have access to the
NetQ Platform for troubleshooting.
High Availability Deployment
NetQ supports a high availability deployment for users who prefer a solution in which the collected data and processing provided by the NetQ Platform remains available through alternate equipment should the platform fail for any reason. In this configuration, three NetQ Platforms are deployed, with one as the master and two as workers (or replicas). Data from the NetQ Agents is sent to all three switches so that if the master NetQ Platform fails, one of the replicas automatically becomes the master and continues to store and provide the telemetry data. This example is based on an OOB management configuration, and modified to support high availability for NetQ.
Cumulus NetQ Operation
In either in-band or out-of-band deployments, NetQ offers networkwide configuration
and device management, proactive monitoring capabilities, and
performance diagnostics for complete management of your network. Each
component of the solution provides a critical element to make this
possible.
The NetQ Agent
From a software perspective, a network
switch has software associated with the hardware platform, the operating
system, and communications. For data centers, the software on a Cumulus
Linux network switch would be similar to the diagram shown here.
The NetQ Agent interacts with the various
components and software on switches and hosts and provides the gathered
information to the NetQ Platform. You can view the data using the NetQ
CLI or UI.
The NetQ Agent polls the user
space applications for information about the performance of the various
routing protocols and services that are running on the switch. Cumulus
Networks supports BGP and OSPF FRRouting (FRR) protocols as
well as static addressing. Cumulus Linux also supports LLDP and MSTP
among other protocols, and a variety of services such as systemd and
sensors . For hosts, the NetQ Agent also polls for performance of
containers managed with Kubernetes. All of this information is used to
provide the current health of the network and verify it is configured
and operating correctly.
For example, if the NetQ Agent learns that an interface has gone down, a
new BGP neighbor has been configured, or a container has moved, it
provides that information to the NetQ
Platform. That information can then be used to notify users of
the operational state change through various channels. By default, data
is logged in the database, but you can use the CLI (netq show events)
or configure the Event Service in NetQ to send the information to a
third-party notification application as well. NetQ supports PagerDuty
and Slack integrations.
The NetQ Agent interacts with the Netlink communications between the
Linux kernel and the user space, listening for changes to the network
state, configurations, routes and MAC addresses. NetQ uses this
information to enable notifications about these changes so that network
operators and administrators can respond quickly when changes are not
expected or favorable.
For example, if a new route is added or a MAC address removed, NetQ
Agent records these changes and sends that information to the
NetQ Platform. Based on the
configuration of the Event Service, these changes can be sent to a
variety of locations for end user response.
The NetQ Agent also interacts with the hardware platform to obtain
performance information about various physical components, such as fans
and power supplies, on the switch. Operational states and temperatures
are measured and reported, along with cabling information to enable
management of the hardware and cabling, and proactive maintenance.
For example, as thermal sensors in the switch indicate that it is
becoming very warm, various levels of alarms are generated. These are
then communicated through notifications according to the Event Service
configuration.
The NetQ Platform
Once the collected data is sent to and stored in the NetQ database, you
can:
Validate configurations, identifying misconfigurations in your
current network, in the past, or prior to deployment,
Monitor communication paths throughout the network,
Notify users of issues and management information,
Anticipate impact of connectivity changes,
and so forth.
Validate Configurations
The NetQ CLI enables validation of your network health through two sets
of commands: netq check and netq show. They extract the information
from the Network Service component and Event service. The Network
Service component is continually validating the connectivity and
configuration of the devices and protocols running on the network. Using
the netq check and netq show commands displays the status of the
various components and services on a networkwide and complete software
stack basis. For example, you can perform a networkwide check on all
sessions of BGP with a single netq check bgp command. The command
lists any devices that have misconfigurations or other operational
errors in seconds. When errors or misconfigurations are present, using
the netq show bgp command displays the BGP configuration on each
device so that you can compare and contrast each device, looking for
potential causes. netq check and netq show commands are available
for numerous components and services as shown in the following table.

Monitor Communication Paths
The trace engine is used to validate the available communication paths
between two network devices. The corresponding netq trace command
enables you to view all of the paths between the two devices and if
there are any breaks in the paths. This example shows two successful
paths between server12 and leaf11, all with an MTU of 9152. The first
command shows the output in path by path tabular mode. The second
command show the same output as a tree.
cumulus@switch:~$ netq trace 10.0.0.13 from 10.0.0.21

bond1.1002 -- swp8 leaf11 vlan1002
This output is read as:
Path 1 traverses the network from server12 out bond1.1002 into
leaf12 interface swp8 out VLAN1002 peerlink-1 into VLAN1002
interface swp6 on leaf11
Path 2 traverses the network from server12 out bond1.1002 into
VLAN1002 interface swp8 on leaf11
If the MTU does not match across the network, or any of the paths or
parts of the paths have issues, that data is called out in the summary
at the top of the output and shown in red along the paths, giving you a
starting point for troubleshooting.
View Historical State and Configuration
All of the check, show and trace commands can be run for the current
status and for a prior point in time. For example, this is useful when
you receive messages from the night before, but are not seeing any
problems now. You can use the netq check command to look for
configuration or operational issues around the time that the messages
are timestamped. Then use the netq show commands to see information
about how the devices in question were configured at that time or if
there were any changes in a given timeframe. Optionally, you can use the
netq trace command to see what the connectivity looked like between
any problematic nodes at that time. This example shows problems occurred
on spine01, leaf04, and server03 last night. The network administrator
received notifications and wants to investigate. The diagram is followed
by the commands to run to determine the cause of a BGP error on spine01.
Note that the commands use the around option to see the results for
last night and that they can be run from any switch in the network.

Manage Network Events
The NetQ notifier manages the events that occur for the devices and
components, protocols and services that it receives from the NetQ
Agents. The notifier enables you to capture and filter events that occur
to manage the behavior of your network. This is especially useful when
an interface or routing protocol goes down and you want to get them back
up and running as quickly as possible, preferably before anyone notices
or complains. You can improve resolution time significantly by creating
filters that focus on topics appropriate for a particular group of
users. You can easily create filters around events related to BGP and
MLAG session states, interfaces, links, NTP and other services,
fans, power supplies, and physical sensor measurements.
For example, for operators responsible for routing, you can create an
integration with a notification application that notifies them of
routing issues as they occur. This is an example of a Slack message
received on a netq-notifier channel indicating that the BGP session on
switch leaf04 interface swp2 has gone down.
Timestamps in NetQ
Every event or entry in the NetQ database is stored with a timestamp of
when the event was captured by the NetQ Agent on the switch or server.
This timestamp is based on the switch or server time where the NetQ
Agent is running, and is pushed in UTC format. It is important to ensure
that all devices are NTP synchronized to prevent events from being
displayed out of order or not displayed at all when looking for events
that occurred at a particular time or within a time window.
Interface state, IP addresses, routes, ARP/ND table (IP neighbor)
entries and MAC table entries carry a timestamp that represents the time
the event happened (such as when a route is deleted or an interface
comes up) - except the first time the NetQ agent is run. If the
network has been running and stable when a NetQ agent is brought up for
the first time, then this time reflects when the agent was started.
Subsequent changes to these objects are captured with an accurate time
of when the event happened.
Data that is captured and saved based on polling, and just about all
other data in the NetQ database, including control plane state (such as
BGP or MLAG), has a timestamp of when the information was captured
rather than when the event actually happened, though NetQ compensates
for this if the data extracted provides additional information to
compute a more precise time of the event. For example, BGP uptime can be
used to determine when the event actually happened in conjunction with
the timestamp.
When retrieving the timestamp, command outputs display the time in three
ways:
For non-JSON output when the timestamp represents the Last Changed
time, time is displayed in actual date and time when the time change occurred
For non-JSON output when the timestamp represents an Uptime, time is
displayed as days, hours, minutes, and seconds from the current time
For JSON output, time is displayed in microseconds that have passed since the Epoch time (January 1, 1970 at 00:00:00 GMT)
This example shows the difference between the timestamp displays.
If a NetQ Agent is restarted on a device, the timestamps for existing
objects are not updated to reflect this new restart time. Their
timestamps are preserved relative to the original start time of the
Agent. A rare exception is if the device is rebooted between the time it
takes the Agent being stopped and restarted; in this case, the time is
once again relative to the start time of the Agent.
Exporting NetQ Data
Data from the NetQ Platform can be exported in a couple of ways:
use the json option to output command results to JSON format for
parsing in other applications
use the UI to export data from the full screen cards
Example Using the CLI
You can check the state of BGP on your network with netq check bgp:
cumulus@leaf01:~$ netq check bgp
Total Nodes: 25, Failed Nodes: 3, Total Sessions: 220 , Failed Sessions: 24,

To open Recent Actions, click . Click on any of the actions to perform that action again.
Search
The Global Search field in the UI header enables you to search for devices and cards. It behaves like most searches and can help you quickly find device information. For more detail on creating and running searches, refer to Create and Run Searches.
Cumulus Networks Logo
Clicking on the Cumulus logo takes you to your favorite workbench. For details about specifying your favorite workbench, refer to Set User Preferences.
Quick Network Health View
Found in the header, the graph and performance rating provide a view into the health of your network at a glance.
On initial start up of the application, it may take up to an hour to reach an accurate health indication as some processes only run every 30 minutes.
Workbenches
A workbench is comprised of a given set of cards. A pre-configured default workbench, Cumulus Workbench, is available to get you started. It contains Device Inventory, Switch Inventory, Alarm and Info Events, and Network Health cards. On initial login, this workbench is opened. You can create your own workbenches and add or remove cards to meet your particular needs. For more detail about managing your data using workbenches, refer to Focus Your Monitoring Using Workbenches.
Cards
Cards present information about your network for monitoring and troubleshooting. This is where you can expect to spend most of your time. Each card describes a particular aspect of the network. Cards are available in multiple sizes, from small to full screen. The level of the content on a card varies in accordance with the size of the card, with the highest level of information on the smallest card to the most detailed information on the full-screen view. Cards are collected onto a workbench where you see all of the data relevant to a task or set of tasks. You can add and remove cards from a workbench, move between cards and card sizes, and make copies of cards to show different levels of data at the same time. For details about working with cards, refer to Access Data with Cards.
User Settings
Each user can customize the NetQ application display, change their account password, and manage their workbenches. This is all performed from User Settings > Profile & Preferences. For details, refer to Set User Preferences.

Create and Run Searches
The Global Search field in the UI header enables you to search for devices or cards. You can create new searches or run existing searches.
Create a Search
As with most search fields, simply begin entering the criteria in the search field. As you type, items that match the search criteria are shown in the search history dropdown along with the last time the search was viewed. Wildcards are not allowed, but this predictive matching eliminates the need for them. By default, the most recent searches are shown. If more have been performed, they can be accessed. This provides a quicker search by reducing entry specifics and suggesting recent searches. Selecting a suggested search from the list provides a preview of the search results to the right.
To create a new search:
Click in the Global Search field.
Enter your search criteria.
Click the device hostname or card workflow in the search list to open the associated information.
If you have more matches than fit in the window, click the See All \# Results link to view all found matches. The count represents the number of devices found. It does not include cards found.
Run a Recent Search
You can re-run a recent search, saving time if you are comparing data from two or more devices.
To re-run a recent search:
Click in the Global Search field.
When the desired search appears in the suggested searches list, select it.
You may need to click See All \# Results to find the desired search. If you do not find it in the list, you may still be able to find it in the Recent Actions list.
Focus Your Monitoring Using Workbenches
Workbenches are an integral structure of the Cumulus NetQ UI. They are where you collect and view the data that is important to you.
There are two types of workbenches:
Default: Provided by Cumulus Networks for use as they exist; changes made to these workbenches cannot be saved
Custom: Created by application users when default workbenches need some adjustments to better meet your needs or a completely different collection of cards is wanted; changes made to these workbenches are saved automatically
Both types of workbenches display a set of cards. Default workbenches are public (available for viewing by all users), whereas Custom workbenches are private (only viewable by the user who created them).
Default Workbenches
In this release, only one default workbench is available, the Cumulus Workbench, to get you started. It contains Device Inventory, Switch Inventory, Alarm and Info Events, and Network Health cards, giving you a high-level view of how your network is operating.
On initial login, the Cumulus Workbench is opened. On subsequent logins, the last workbench you had displayed is opened.
Custom Workbenches
Users with either administrative or user roles can create and save as many custom workbenches as suits their needs. For example, a user might create a workbench that:
Shows all of the selected cards for the past week and one that shows all of the selected cards for the past 24 hours
Only has data about your virtual overlays; EVPN plus events cards
Has selected switches that you are troubleshooting
Focused on application or user account management
And so forth.
Create a Workbench
To create a workbench:
Click in the workbench header.
Enter a name for the workbench.
Click Create to open a blank new workbench, or Cancel to discard the workbench.
Add cards to the workbench using or .
Refer to Access Data with Cards for information about interacting with cards on your workbenches.
Remove a Workbench
Once you have created a number of custom workbenches, you might find that you no longer need some of them. As an administrative user, you can remove any workbench, except for the default Cumulus Workbench. Users with a user role can only remove workbenches they have created.
To remove a workbench:
Click in the application header to open the User Settings options.
Click Profile & Preferences.
Locate the Workbenches card.
Hover over the workbench you want to remove, and click Delete.
Open an Existing Workbench
There are several options for opening workbenches:
Open through Workbench Header
Click next to the current workbench name and locate the workbench
Under My Home, click the name of your favorite workbench
Under My Most Recent, click the workbench if in list
Search by workbench name
Click All My WB to open all workbenches and select it from the list
Open through Main Menu
Click (Main Menu) and select the workbench from the Favorites or NetQ columns
Open through Cumulus logo
Click the logo in the header to open your favorite workbench
Manage Auto-refresh for Your Workbenches
With NetQ 2.3.1 and later, you can specify how often to update the data displayed on your workbenches. Three refresh rates are available:
Analyze: updates every 30 seconds
Debug: updates every minute
Monitor: updates every two (2) minutes
By default, auto-refresh is enabled and configured to update every 30 seconds.
Disable/Enable Auto-refresh
To disable or pause auto-refresh of your workbenches, simply click the Refresh icon. This toggles between the two states, Running and Paused, where indicates it is currently disabled and indicates it is currently enabled.
While having the workbenches update regularly is good most of the time, you may find that you want to pause the auto-refresh feature when you are troubleshooting and you do not want the data to change on a given set of cards temporarily. In this case, you can disable the auto-refresh and then enable it again when you are finished.
View Current Settings
To view the current auto-refresh rate and operational status, hover over the Refresh icon on a workbench header, to open the tool tip as follows:
Change Settings
To modify the auto-refresh setting:
Click on the Refresh icon.
Select the refresh rate you want. The refresh rate is applied immediately. A check mark is shown next to the current selection.
Manage Workbenches
To manage your workbenches as a group, either:
Click next to the current workbench name, then click Manage My WB.
Click , select Profiles & Preferences option.
Both of these open the Profiles & Preferences page. Look for the Workbenches card and refer to Manage Your Workbenches for more information.
Access Data with Cards
Cards present information about your network for monitoring and troubleshooting. This is where you can expect to spend most of your time. Each card describes a particular aspect of the network. Cards are available in multiple sizes, from small to full screen. The level of the content on a card varies in accordance with the size of the card, with the highest level of information on the smallest card to the most detailed information on the full-screen card. Cards are collected onto a workbench where you see all of the data relevant to a task or set of tasks. You can add and remove cards from a workbench, move between cards and card sizes, change the time period of the data shown on a card, and make copies of cards to show different levels of data at the same time.
Card Sizes
The various sizes of cards enables you to view your content at just the right level. For each aspect that you are monitoring there is typically a single card, that presents increasing amounts of data over its four sizes. For example, a snapshot of your total inventory may be sufficient, but to monitor the distribution of hardware vendors may requires a bit more space.
Small Cards
Small cards are most effective at providing a quick view of the performance or statistical value of a given aspect of your network. They are commonly comprised of an icon to identify the aspect being monitored, summary performance or statistics in the form of a graph and/or counts, and often an indication of any related events. Other content items may be present. Some examples include a Devices Inventory card, a Switch Inventory card, an Alarm Events card, an Info Events card, and a Network Health card, as shown here:
Medium Cards
Medium cards are most effective at providing the key measurements for a given aspect of your network. They are commonly comprised of an icon to identify the aspect being monitored, one or more key measurements that make up the overall performance. Often additional information is also included, such as related events or components. Some examples include a Devices Inventory card, a Switch Inventory card, an Alarm Events card, an Info Events card, and a Network Health card, as shown here. Compare these with their related small- and large-sized cards.
Large Cards
Large cards are most effective at providing the detailed information for monitoring specific components or functions of a given aspect of your network. These can aid in isolating and resolving existing issues or preventing potential issues. They are commonly comprised of detailed statistics and graphics. Some large cards also have tabs for additional detail about a given statistic or other related information. Some examples include a Devices Inventory card, an Alarm Events card, and a Network Health card, as shown here. Compare these with their related small- and medium-sized cards.
Full-Screen Cards
Full-screen cards are most effective for viewing all available data about an aspect of your network all in one place. When you cannot find what you need in the small, medium, or large cards, it is likely on the full-screen card. Most full-screen cards display data in a grid, or table; however, some contain visualizations. Some examples include All Events card and All Switches card, as shown here.

Card Workflows
The UI provides a number of card workflows. Card workflows focus on a particular aspect of your network and are a linked set of each size card-a small card, a medium card, one or more large cards, and one or more full screen cards. The following card workflows are available:
Network Health: networkwide view of network health
Devices|Switches: health of a given switch
Inventory|Devices: information about all switches and hosts in the network
Inventory|Switches: information about the components on a given switch
Events|Alarms: information about all critical severity events in the system
Events|Info: information about all warning, info, and debug events in the system
Network Services: information about the network services and sessions
Validation Request (and Results): networkwide validation of network protocols and services
Trace Request (and Results): find available paths between two devices in the network fabric
Network Snapshot: view and compare the network state at various times
Access a Card Workflow
You can access a card workflow in multiple ways:
For workbenches available from the main menu, open the workbench that contains the card flow
Open a prior search
Add it to a workbench
Search for it
If you have multiple cards open on your workbench already, you might need to scroll down to see the card you have just added.
To open the card workflow through an existing workbench:
Click in the workbench task bar.
Select the relevant workbench.
The workbench opens, hiding your previous workbench.
To open the card workflow from Recent Actions:
Click in the application header.

Card Interactions
Every card contains a standard set of interactions, including the ability to switch between card sizes, and change the time period of the presented data. Most cards also have additional actions that can be taken, in the form of links to other cards, scrolling, and so forth. The four sizes of cards for a particular aspect of the network are connected into a flow; however, you can have duplicate cards displayed at the different sizes. Cards with tabular data provide filtering, sorting, and export of data. The medium and large cards have descriptive text on the back of the cards.
To access the time period, card size, and additional actions, hover over the card. These options appear, covering the card header, enabling you to select the desired option.
Add Cards to Your Workbench
You can add one or more cards to a workbench at any time. To add Devices|Switches cards, refer to Add Switch Cards to Your Workbench. For all other cards, follow the steps in this section.
To add one or more cards:
Click to open the Cards modal.
Scroll down until you find the card you want to add, select the category of cards, or use Search to find the card you want to add.
This example uses the category tab to narrow the search for a card.
Click on each card you want to add.
As you select each card, it is grayed out and a appears on top of it. If you have selected one or more cards using the category option, you can selected another category without losing your current selection. Note that the total number of cards selected for addition to your workbench is noted at the bottom.
Also note that if you change your mind and do not want to add a particular card you have selected, simply click on it again to remove it from the cards to be added. Note the total number of cards selected decreases with each card you remove.
When you have selected all of the cards you want to add to your workbench, you can confirm which cards have been selected by clicking the Cards Selected link. Modify your selection as needed.
Click Open Cards to add the selected cards, or Cancel to return to your workbench without adding any cards.
The cards are placed at the end of the set of cards currently on the workbench. You might need to scroll down to see them. By default, the medium size of the card is added to your workbench for all except the Validation and Trace cards. These are added in the large size by default. You can rearrange the cards as described in Reposition a Card on Your Workbench.
Add Switch Cards to Your Workbench
You can add switch cards to a workbench at any time. For all other cards, follow the steps in Add Cards to Your Workbench. You can either add the card through the Switches icon on a workbench header or by searching for it through Global Search.
To add a switch card using the icon:
Click to open the Add Switch Card modal.
Begin entering the hostname of the switch you want to monitor.
Select the device from the suggestions that appear.
If you attempt to enter a hostname that is unknown to NetQ, a pink border appears around the entry field and you are unable to select Add. Try checking for spelling errors. If you feel your entry is valid, but not an available choice, consult with your network administrator.
Optionally select the small or large size to display instead of the medium size.
Click Add to add the switch card to your workbench, or Cancel to return to your workbench without adding the switch card.
To open the switch card by searching:
Click in Global Search.

Removing cards is handled one card at a time.
To remove a card:
Hover over the card you want to remove.
Click (More Actions menu).
Click Remove.
The card is removed from the workbench, but not from the application.
Change the Time Period for the Card Data
All cards have a default time period for the data shown on the card, typically the last 24 hours. You can change the time period to view the data during a different time range to aid analysis of previous or existing issues.
To change the time period for a card:
Hover over any card.
Click in the header.
Select a time period from the dropdown list.
Changing the time period in this manner only changes the time period for the given card.
Switch to a Different Card Size
You can switch between the different card sizes at any time. Only one size is visible at a time. To view the same card in different sizes, open a second copy of the card.
To change the card size:
Hover over the card.
Hover over the Card Size Picker and move the cursor to the right or left until the desired size option is highlighted.
Single width opens a small card. Double width opens a medium card. Triple width opens large cards. Full width opens full-screen cards.
Click the Picker.
The card changes to the selected size, and may move its location on the workbench.
View a Description of the Card Content
When you hover over a medium or large card, the bottom right corner turns up and is highlighted. Clicking the corner turns the card over where a description of the card and any relevant tabs are described. Hover and click again to turn it back to the front side.
Reposition a Card on Your Workbench
You can also move cards around on the workbench, using a simple drag and drop method.
To move a card:
Simply click and drag the card to left or right of another card, next to where you want to place the card.
Release your hold on the card when the other card becomes highlighted with a dotted line. In this example, we are moving the medium Network Health card to the left of the medium Devices Inventory card.

NetQ Command Line Overview
The NetQ CLI provides access to all of the network state and event information collected by the NetQ Agents. It behaves the same way most CLIs behave, with groups of commands used to display related information, the ability to use TAB completion when entering commands, and to get help for given commands and options. The commands are grouped into four categories: check, show, config, and trace.
The NetQ command line interface only runs on switches and server hosts implemented with Intel x86 or ARM-based architectures. If you are unsure what architecture your switch or server employs, check the Cumulus Hardware Compatibility List and verify the value in the Platforms tab > CPU column.
CLI Access
When NetQ is installed or upgraded, the CLI may also be installed and enabled on your NetQ server or appliance and hosts. Refer to the Install NetQ topic for details.
To access the CLI from a switch or server:
Log in to the device. This example uses the default username of cumulus and a hostname of switch.
<computer>:~<username>$ ssh cumulus@switch
Enter your password to reach the command prompt. The default password is CumulusLinux! For example:
Enter passphrase for key '/Users/<username>/.ssh/id_rsa': <enter CumulusLinux! here>

cumulus@switch:~$
Run commands. For example:
cumulus@switch:~$ netq show agents
cumulus@switch:~$ netq check bgp
Command Line Basics
This section describes the core structure and behavior of the NetQ CLI. It includes the following:
The Cumulus NetQ command line has a flat structure as opposed to a modal structure. This means that all commands can be run from the primary prompt instead of only in a specific mode. For example, some command lines require the administrator to switch between a configuration mode and an operation mode. Configuration commands can only be run in the configuration mode and operational commands can only be run in operation mode. This structure requires the administrator to switch between modes to run commands which can be tedious and time consuming. Cumulus NetQ command line enables the administrator to run all of its commands at the same level.
Command Syntax
NetQ CLI commands all begin with netq. Cumulus NetQ commands fall into one of four syntax categories: validation (check), monitoring (show), configuration, and trace.
netq check <network-protocol-or-service> [options]
netq show <network-protocol-or-service> [options]
netq config <action> <object> [options]
netq trace <destination> from <source> [options]
Symbols
Meaning
Parentheses ( )
Grouping of required parameters. Choose one.
Square brackets [ ]
Single or group of optional parameters. If more than one object or keyword is available, choose one.
Angle brackets < >
Required variable. Value for a keyword or option; enter according to your deployment nomenclature.
Pipe |
Separates object and keyword options, also separates value options; enter one object or keyword and zero or one value.
For example, in the netq check command:
[<hostname>] is an optional parameter with a variable value named hostname
<network-protocol-or-service> represents a number of possible key words, such as agents, bgp, evpn, and so forth
<options> represents a number of possible conditions for the given object, such as around, vrf, or json
Thus some valid commands are:
netq leaf02 check agents json
netq show bgp
netq config restart cli
netq trace 10.0.0.5 from 10.0.0.35
Command Output
The command output presents results in color for many commands. Results with errors are shown in red, and warnings are shown in yellow. Results without errors or warnings are shown in either black or green. VTEPs are shown in blue. A node in the pretty output is shown in bold, and a router interface is wrapped in angle brackets (< >). To view the output with only black text, run the netq config del color command. You can view output with colors again by running netq config add color.
All check and show commands are run with a default timeframe of now to one hour ago, unless you specify an approximate time using the around keyword. For example, running netq check bgp shows the status of BGP over the last hour. Running netq show bgp around 3h shows the status of BGP three hours ago.
Command Prompts
NetQ code examples use the following prompts:
cumulus@switch:~$ Indicates the user cumulus is logged in to a switch to run the example command
cumulus@host:~$ Indicates the user cumulus is logged in to a host to run the example command
cumulus@netq-appliance:~$ Indicates the user cumulus is logged in to either the NetQ Appliance or NetQ Cloud Appliance to run the command
cumulus@hostname:~$ Indicates the user cumulus is logged in to a switch, host or appliance to run the example command
To use the NetQ CLI, the switches must be running the Cumulus Linux operating system (OS), NetQ Platform or NetQ Collector software, the NetQ Agent, and the NetQ CLI. The hosts must be running CentOS, RHEL, or Ubuntu OS, the NetQ Agent, and the NetQ CLI. Refer to the Install NetQ topic for details.
Command Completion
As you enter commands, you can get help with the valid keywords or options using the Tab key. For example, using Tab completion with netq check displays the possible objects for the command, and returns you to the command prompt to complete the command.
cumulus@switch:~$ netq check <<press Tab>>
agents : Netq agent
bgp : BGP info
cl-version : Cumulus Linux version
clag : Cumulus Multi-chassis LAG
evpn : EVPN
interfaces : network interface port
license : License information
mlag : Multi-chassis LAG (alias of clag)
mtu : Link MTU
ntp : NTP
ospf : OSPF info
sensors : Temperature/Fan/PSU sensors
vlan : VLAN
vxlan : VXLAN data path
cumulus@switch:~$ netq check
Command Help
As you enter commands, you can get help with command syntax by entering help at various points within a command entry. For example, to find out what options are available for a BGP check, enter help after entering a portion of the netq check command. In this example, you can see that there are no additional required parameters and three optional parameters, hostnames, vrf and around, that can be used with a BGP check.
To see a list of all NetQ commands and keyword help, run:
cumulus@switch:~$ netq help list
Command History
The CLI stores commands issued within a session, which enables you to review and rerun commands that have already been run. At the command prompt, press the Up Arrow and Down Arrow keys to move back and forth through the list of commands previously entered. When you have found a given command, you can run the command by pressing Enter, just as you would if you had entered it manually. Optionally you can modify the command before you run it.
Command Categories
While the CLI has a flat structure, the commands can be conceptually grouped into four functional categories:
The netqcheck commands enable the network administrator to validate the current or historical state of the network by looking for errors and misconfigurations in the network. The commands run fabric-wide validations against various configured protocols and services to determine how well the network is operating. Validation checks can be performed for the following:
agents: NetQ Agents operation on all switches and hosts
bgp: BGP (Border Gateway Protocol) operation across the network
fabric
clag: Cumulus Multi-chassis LAG (link aggregation) operation
mlag: Cumulus Multi-chassis LAG (link aggregation) operation
mtu: Link MTU (maximum transmission unit) consistency across paths
ntp: NTP (Network Time Protocol) operation
ospf: OSPF (Open Shortest Path First) operation
sensors: Temperature/Fan/PSU sensor operation
vlan: VLAN (Virtual Local Area Network) operation
vxlan: VXLAN (Virtual Extensible LAN) data path operation
The commands take the form of netq check <network-protocol-or-service> [options], where the options vary according to the protocol or service.
This example shows the output for the netq check bgp command, followed by the same command using the json option. If there had been any failures, they would be have been listed below the summary results or in the failedNodes section, respectively.
cumulus@switch:~$ netq check bgp
bgp check result summary:
Checked nodes : 8
Total nodes : 8
Rotten nodes : 0
Failed nodes : 0
Warning nodes : 0
Additional summary:
Total Sessions : 30
Failed Sessions : 0
Session Establishment Test : passed
Address Families Test : passed
Router ID Test : passed
The netq show commands enable the network administrator to view
details about the current or historical configuration and status of the
various protocols or services. The configuration and status can be shown
for the following:
address-history: Address history info for a IP address / prefix
agents: NetQ Agents status on switches and hosts

The commands take the form of netq [<hostname>] show <network-protocol-or-service> [options], where the options vary according to the protocol or service. The commands can be restricted from showing the information for all devices to showing information for a selected device using the hostname option.
This example shows the standard and restricted output for the netq show agents command.
cumulus@switch:~$ netq leaf01 show agents
Matching agents records:

Configuration Commands
The netq config and netq notification commands enable the network administrator to manage NetQ Agent and CLI server configuration, set up container monitoring, and event notification.
The agent configuration commands enable you to add and remove agents from switches and hosts, start and stop agent operations, debug the agent, specify default commands, and enable or disable a variety of monitoring features (including Kubernetes, sensors, FRR (FRRouting), CPU usage limit, and What Just Happened).
Commands apply to one agent at a time, and are run from the switch or host where the NetQ Agent resides.
This example shows how to view the NetQ Agent configuration.
cumulus@switch:~$ netq config show agent
netq-agent value default
--------------------- --------- ---------
enable-opta-discovery True True
exhibitport
agenturl
server 127.0.0.1 127.0.0.1
exhibiturl
vrf default default
agentport 8981 8981
port 31980 31980
After making configuration changes to your agents, you must restart the agent for the changes to take effect. Use the netq config restart agent command.
CLI Configuration
The CLI commands enable the network administrator to configure and manage the CLI component. These commands enable you to add or remove CLI (essentially enabling/disabling the service), start and restart it, and view the configuration of the service.
Commands apply to one device at a time, and are run from the switch or host where the CLI is run.
The CLI configuration commands include:
netq config add cli server
netq config del cli server
netq config show cli premises [json]
netq config show (cli|all) [json]
netq config (status|restart) cli
This example shows how to restart the CLI instance.
cumulus@switch~:$ netq config restart cli
This example shows how to enable the CLI on a NetQ On-premises Appliance or Virtual Machine (VM).
cumulus@switch~:$ netq config add cli server 10.1.3.101
This example shows how to enable the CLI on a NetQ Cloud Appliance or VM for the Chicago premises and the default port.
netq config add cli server api.netq.cumulusnetworks.com access-key <user-access-key> secret-key <user-secret-key> premises chicago port 443
Event Notification Commands
The notification configuration commands enable you to add, remove and show notification application integrations. These commands create the channels, filters, and rules needed to control event messaging. The commands include:
Refer to Configure Notifications for details about using these commands and additional examples.
Trace Commands
The trace commands enable the network administrator to view the available paths between two nodes on the network currently and at a time in the past. You can perform a layer 2 or layer 3 trace, and view the output in one of three formats (json, pretty, and detail). JSON output provides the output in a JSON file format for ease of importing to other applications or software. Pretty output lines up the paths in a pseudo-graphical manner to help visualize multiple paths. Detail output is useful for traces with higher hop counts where the pretty output wraps lines, making it harder to interpret the results. The detail output displays a table with a row for each path.
This topic is intended for network administrators who are responsible for installation, setup, and maintenance of Cumulus NetQ in their data center or campus environment. NetQ offers the ability to monitor and manage your network infrastructure and operational health with simple tools based on open source Linux. This topic provides instructions and information about installing, backing up, and upgrading NetQ. It also contains instructions for integrating with an LDAP server and Grafana.
Before you get started, you should review the release notes for this version.
Install NetQ
The Cumulus NetQ software contains several components that must be installed, including the NetQ applications, the database, and the NetQ Agents. NetQ can be deployed in two arrangements:
All software components installed locally (the applications and database are installed as a single entity, called the NetQ Platform) running on the NetQ On-premises Appliance or NetQ On-premises Virtual Machine (VM); known hereafter as the on-premises solution
Only the aggregation and forwarding application software installed locally (called the NetQ Collector) running on the NetQ Cloud Appliance or NetQ Cloud VM, with the database and all other applications installed in the cloud; known hereafter as the cloud solution
The NetQ Agents reside on the switches and hosts being monitored in your network.
For the on-premises solution, the NetQ Agents collect and transmit data from the switches and/or hosts back to the NetQ On-premises Appliance or Virtual Machine running the NetQ Platform, which in turn processes and stores the data in its database. This data is then provided for display through several user interfaces.
For the cloud solution, the NetQ Agent function is exactly the same, transmitting collected data, but instead sends it to the NetQ Collector containing only the aggregation and forwarding application. The NetQ Collector then transmits this data to Cumulus Networks cloud-based infrastructure for further processing and storage. This data is then provided for display through the same user interfaces as the on-premises solution. In this solution, the browser interface can be pointed to the local NetQ Cloud Appliance or VM, or directly to netq.cumulusnetworks.com.
Installation Choices
There are several choices that you must make to determine what steps you need to perform to install the NetQ solution. First and foremost, you must determine whether you intend to deploy the solution fully on your premises or if you intend to deploy the cloud solution. Secondly, you must decide whether you are going to deploy a Virtual Machine on your own hardware or use one of the Cumulus NetQ appliances. Thirdly, you also must determine whether you want to install the software on a single server or as a server cluster. Finally, if you have an existing on-premises solution and want to save your existing NetQ data, you must backup that data before installing the new software.
The documentation walks you through these choices and then provides the instructions specific to your selections.
Installation Workflow Summary
No matter how you answer the questions above, the installation workflow can be summarized as follows:
Prepare physical server or virtual machine.
Install the software (NetQ Platform or NetQ Collector).
Install and configure NetQ Agents on switches and hosts.
Install and configure NetQ CLI on switches and hosts (optional, but useful).
This topic walks you through the NetQ System installation decisions and then provides installation steps based on those choices. If you are already comfortable with your installation choices, you may use the matrix in Install NetQ Quick Start to go directly to the installation steps.
To install NetQ 3.2.x, you must first decide whether you want to install the NetQ System in an on-premises or cloud deployment. Both deployment options provide secure access to data and features useful for monitoring and troubleshooting your network, and each has its benefits.
It is common to select an on-premises deployment model if you want to host all required hardware and software at your location, and you have the in-house skill set to install, configure, and maintain it—including performing data backups, acquiring and maintaining hardware and software, and integration and license management. This model is also a good choice if you want very limited or no access to the Internet from switches and hosts in your network. Some companies simply want complete control of the their network, and no outside impact.
If, however, you find that you want to host only a small server on your premises and leave the details up to Cumulus Networks, then a cloud deployment might be the right choice for you. With a cloud deployment, a small local server connects to the NetQ Cloud service over selected ports or through a proxy server. Only data aggregation and forwarding is supported. The majority of the NetQ applications are hosted and data storage is provided in the cloud. Cumulus handles the backups and maintenance of the application and storage. This model is often chosen when it is untenable to support deployment in-house or if you need the flexibility to scale quickly, while also reducing capital expenses.
Click the deployment model you want to use to continue with installation:
On-premises deployments of NetQ can use a single server or a server cluster. In either case, you can use either the Cumulus NetQ Appliance or your own server running a KVM or VMware Virtual Machine (VM). This topic walks you through the installation for each of these on-premises options.
The next installation step is to decide whether you are deploying a single server or a server cluster. Both options provide the same services and features. The biggest difference is in the number of servers to be deployed and in the continued availability of services running on those servers should hardware failures occur.
A single server is easier to set up, configure and manage, but can limit your ability to scale your network monitoring quickly. Multiple servers is a bit more complicated, but you limit potential downtime and increase availability by having more than one server that can run the software and store the data.
Select the standalone single-server arrangements for smaller, simpler deployments. Be sure to consider the capabilities and resources needed on this server to support the size of your final deployment.
Select the server cluster arrangement to obtain scalability and high availability for your network. You can configure one master node and up to nine worker nodes.
Click the server arrangement you want to use to begin installation:
Cloud deployments of NetQ can use a single server or a server cluster on site. The NetQ database remains in the cloud either way. You can use either the Cumulus NetQ Cloud Appliance or your own server running a KVM or VMware Virtual Machine (VM). This topic walks you through the installation for each of these cloud options.

cumulus@hostname:~$ sudo opta-check
Change the hostname for the VM from the default value.
The default hostname for the NetQ Virtual Machines is ubuntu. Change the hostname to fit your naming conventions while meeting Internet and Kubernetes naming standards.
Kubernetes requires that hostnames are composed of a sequence of labels concatenated with dots. For example, “en.wikipedia.org” is a hostname. Each label must be from 1 to 63 characters long. The entire hostname, including the delimiting dots, has a maximum of 253 ASCII characters.
The Internet standards (RFCs) for protocols specify that labels may contain only the ASCII letters a through z (in lower case), the digits 0 through 9, and the hyphen-minus character ('-').
Re-run the Bootstrap CLI. This example uses interface eth0. Replace this with your updated IP address, hostname or interface using the interface or ip-addr option.
If you are using Flannel with a container environment on your network, you may need to change its default IP address ranges if they conflict with other addresses on your network. This can only be done one time during the first installation.
The address range is 10.244.0.0/16. NetQ overrides the original Flannel default, which is 10.1.0.0/16.
To change the default address range, use the CLI with the pod-ip-range option. For example:

Verify the worker node is ready for installation. Fix any errors indicated before installing the NetQ software.
Provide a password using the password option if required. Allow about five to ten minutes for this to complete, and only then continue to the next step.
If this step fails for any reason, you can run netq bootstrap reset on the new worker node and then try again.
Repeat Steps 9 through 14 for each additional worker node you want in your cluster.
Considerations for Container Environments
Flannel Virtual Networks
If you are using Flannel with a container environment on your network, you may need to change its default IP address ranges if they conflict with other addresses on your network. This can only be done one time during the first installation.
The address range is 10.244.0.0/16. NetQ overrides the original Flannel default, which is 10.1.0.0/16.
To change the default address range, use the CLI with the pod-ip-range option. For example:

Change the hostname for the VM from the default value.
The default hostname for the NetQ Virtual Machines is ubuntu. Change the hostname to fit your naming conventions while meeting Internet and Kubernetes naming standards.
Kubernetes requires that hostnames are composed of a sequence of labels concatenated with dots. For example, “en.wikipedia.org” is a hostname. Each label must be from 1 to 63 characters long. The entire hostname, including the delimiting dots, has a maximum of 253 ASCII characters.
The Internet standards (RFCs) for protocols specify that labels may contain only the ASCII letters a through z (in lower case), the digits 0 through 9, and the hyphen-minus character ('-').
Re-run the Bootstrap CLI. This example uses interface eth0. Replace this with your updated IP address, hostname or interface using the interface or ip-addr option.

Or, for a Bridged VM, where the VM attaches to a bridge which has already been setup to allow for external access:
Replace network bridge value (br0 in the above example) with the name of the (pre-existing) bridge interface where the VM is connected to the external network.
Make note of the name used during install as this is needed in a later step.
Watch the boot process in another terminal window.
$ virsh console netq_ts
Log in to the VM and change the password.

Verify the master node is ready for installation. Fix any errors indicated before installing the NetQ software.
cumulus@hostname:~$ sudo opta-check-cloud
Change the hostname for the VM from the default value.
The default hostname for the NetQ Virtual Machines is ubuntu. Change the hostname to fit your naming conventions while meeting Internet and Kubernetes naming standards.
Kubernetes requires that hostnames are composed of a sequence of labels concatenated with dots. For example, “en.wikipedia.org” is a hostname. Each label must be from 1 to 63 characters long. The entire hostname, including the delimiting dots, has a maximum of 253 ASCII characters.
The Internet standards (RFCs) for protocols specify that labels may contain only the ASCII letters a through z (in lower case), the digits 0 through 9, and the hyphen-minus character ('-').
Allow about five to ten minutes for this to complete, and only then continue to the next step.
If this step fails for any reason, you can run netq bootstrap reset and then try again.
If you have changed the IP address or hostname of the NetQ Cloud VM after this step, you need to re-register this address with NetQ as follows:
Reset the VM.
cumulus@hostname:~$ netq bootstrap reset
Re-run the Bootstrap CLI. This example uses interface eth0. Replace this with your updated IP address, hostname or interface using the interface or ip-addr option.
Verify that your first worker node meets the VM requirements, as described in Step 1.
Confirm that the needed ports are open for communications, as described in Step 2.
Open your hypervisor and setup the VM in the same manner as for the master node.

Considerations for Container Environments
Flannel Virtual Networks
If you are using Flannel with a container environment on your network, you may need to change its default IP address ranges if they conflict with other addresses on your network. This can only be done one time during the first installation.
The address range is 10.244.0.0/16. NetQ overrides the original Flannel default, which is 10.1.0.0/16.
To change the default address range, use the CLI with the pod-ip-range option. For example:
This topic describes how to prepare your single, NetQ On-premises Appliance for installation of the NetQ Platform software.
Inside the box that was shipped to you, you’ll find:
Your Cumulus NetQ On-premises Appliance (a Supermicro 6019P-WTR server)
Hardware accessories, such as power cables and rack mounting gear (note that network cables and optics ship separately)
Information regarding your order
For more detail about hardware specifications (including LED layouts and FRUs like the power supply or fans, and accessories like included cables) or safety and environmental information, refer to the user manual and quick reference guide.
Install the Appliance
After you unbox the appliance:
Mount the appliance in the rack.
Connect it to power following the procedures described in your appliance's user manual.
Connect the Ethernet cable to the 1G management port (eno1).
Power on the appliance.
If your network runs DHCP, you can configure NetQ over the network. If DHCP is not enabled, then you configure the appliance using the console cable provided.
Configure the Password, Hostname and IP Address
Change the password and specify the hostname and IP address for the appliance before installing the NetQ software.
Log in to the appliance using the default login credentials:
Username: cumulus
Password: cumulus
Change the password using the passwd command:
cumulus@hostname:~$ passwd
Changing password for cumulus.
(current) UNIX password: cumulus
Enter new UNIX password:

The default hostname for the NetQ On-premises Appliance is netq-appliance. Change the hostname to fit your naming conventions while meeting Internet and Kubernetes naming standards.
Kubernetes requires that hostnames are composed of a sequence of labels concatenated with dots. For example, “en.wikipedia.org” is a hostname. Each label must be from 1 to 63 characters long. The entire hostname, including the delimiting dots, has a maximum of 253 ASCII characters.
The Internet standards (RFCs) for protocols specify that labels may contain only the ASCII letters a through z (in lower case), the digits 0 through 9, and the hyphen-minus character ('-').
The appliance contains two Ethernet ports. Port eno1, is dedicated for out-of-band management. This is where NetQ Agents should send the telemetry data collected from your monitored switches and hosts. By default, eno1 uses DHCPv4 to get its IP address. You can view the assigned IP address using the following command:
cumulus@hostname:~$ ip -4 -brief addr show eno1
eno1 UP 10.20.16.248/24
Alternately, you can configure the interface with a static IP address by editing the /etc/netplan/01-ethernet.yaml Ubuntu Netplan configuration file.
For example, to set your network interface eno1 to a static IP address of 192.168.1.222 with gateway 192.168.1.1 and DNS server as 8.8.8.8 and 8.8.4.4:

Run the Bootstrap CLI. Be sure to replace the eno1 interface used in this example with the interface or IP address on the appliance used to listen for NetQ Agents.
Allow about five to ten minutes for this to complete, and only then continue to the next step.
If this step fails for any reason, you can run netq bootstrap reset [purge-db|keep-db] and then try again.
If you have changed the IP address or hostname of the NetQ On-premises Appliance after this step, you need to re-register this address with NetQ as follows:
Reset the appliance, indicating whether you want to purge any NetQ DB data or keep it.

Verify the master NetQ Cloud Appliance is ready for installation. Fix any errors indicated before installing the NetQ software.
cumulus@hostname:~$ sudo opta-check-cloud
Run the Bootstrap CLI. Be sure to replace the eno1 interface used in this example with the interface or IP address on the appliance used to listen for NetQ Agents.
Allow about five to ten minutes for this to complete, and only then continue to the next step.
If this step fails for any reason, you can run netq bootstrap reset and then try again.
If you have changed the IP address or hostname of the NetQ Cloud Appliance after this step, you need to re-register this address with NetQ as follows:
Reset the appliance.
cumulus@hostname:~$ netq bootstrap reset
Re-run the Bootstrap CLI on the appliance. This example uses interface eno1. Replace this with your updated IP address, hostname or interface using the interface or ip-addr option.
Provide a password using the password option if required. Allow about five to ten minutes for this to complete, and only then continue to the next step.
If this step fails for any reason, you can run netq bootstrap reset on the new worker node and then try again.
Repeat Steps 5-10 for each additional worker NetQ Cloud Appliance.
Considerations for Container Environments
Flannel Virtual Networks
If you are using Flannel with a container environment on your network, you may need to change its default IP address ranges if they conflict with other addresses on your network. This can only be done one time during the first installation.
The address range is 10.244.0.0/16. NetQ overrides the original Flannel default, which is 10.1.0.0/16.
To change the default address range, use the CLI with the pod-ip-range option. For example:
Prepare Your Existing NetQ Appliances for a NetQ 3.2 Deployment
This topic describes how to prepare a NetQ 2.4.x or earlier NetQ Appliance before installing NetQ 3.x. The steps are the same for both the on-premises and cloud appliances. The only difference is the software you download for each platform. On completion of the steps included here, you will be ready to perform a fresh installation of NetQ 3.x.
The preparation workflow is summarized in this figure:
To prepare your appliance:
Verify that your appliance is a supported hardware model.
For on-premises solutions using the NetQ On-premises Appliance, optionally back up your NetQ data.
Run the backup script to create a backup file in /opt/<backup-directory>.
Be sure to replace the backup-directory option with the name of the directory you want to use for the backup file. This location must be somewhere that is off of the appliance to avoid it being overwritten during these preparation steps.
Ubuntu OS should be installed on the SSD disk. Select Micron SSD with ~900 GB at step#9 in the aforementioned instructions.
Set the default username to cumulus and password to CumulusLinux!.
When prompted, select Install SSH server.
Configure networking.
Ubuntu uses Netplan for network configuration. You can give your appliance an IP address using DHCP or a static address.
Create and/or edit the /etc/netplan/01-ethernet.yaml Netplan configuration file.

...
deb [arch=amd64] https://apps3.cumulusnetworks.com/repos/deb bionic netq-latest
...
The use of netq-latest in this example means that a get to the repository always retrieves the latest version of NetQ, even in the case where a major version update has been made. If you want to keep the repository on a specific version - such as netq-3.1 - use that instead.
Select 3.2 from the Version list, and then select 3.2.1 from the submenu.
Select Bootstrap from the Hypervisor/Platform list.
Note that the bootstrap file is the same for both appliances.
Scroll down and click Download.
Select Appliance for the NetQ On-premises Appliance or Appliance (Cloud) for the NetQ Cloud Appliance from the Hypervisor/Platform list.
Make sure you select the right install choice based on whether you are preparing the on-premises or cloud version of the appliance.
Scroll down and click Download.
Copy these two files, netq-bootstrap-3.2.1.tgz and either NetQ-3.2.1.tgz (on-premises) or NetQ-3.2.1-opta.tgz (cloud), to the /mnt/installables/ directory on the appliance.
Verify that the needed files are present and of the correct release. This example shows on-premises files. The only difference for cloud files is that it should list NetQ-3.2.1-opta.tgz instead of NetQ-3.2.1.tgz.
cumulus@<hostname>:~$ dpkg -l | grep netq

cumulus@<hostname>:~$ cd /mnt/installables/
cumulus@<hostname>:/mnt/installables$ ls
NetQ-3.2.1.tgz netq-bootstrap-3.2.1.tgz
Run the bootstrap CLI on your appliance. Be sure to replace the eth0 interface used in this example with the interface or IP address on the appliance used to listen for NetQ Agents.
If you are creating a server cluster, you need to prepare each of those appliances as well. Repeat these steps if you are using a previously deployed appliance or refer to Install the NetQ System for a new appliance.
You can now install the NetQ software using the Admin UI using the default basic installation or an advanced installation.

Install NetQ Using the CLI
You can now install the NetQ software using the NetQ CLI.
This is the final set of steps for installing NetQ. If you have not already performed the installation preparation steps, go to Install the NetQ System before continuing here.
To install NetQ:
Log in to your NetQ platform server, NetQ Appliance, NetQ Cloud Appliance or the master node of your cluster.
Install the software.
Run the following command on your NetQ platform server or NetQ Appliance:
cumulus@hostname:~$ netq install standalone full interface eth0 bundle /mnt/installables/NetQ-3.2.1.tgz
You can specify the IP address instead of the interface name here: use ip-addr <IP address> in place of interface <ifname> above.
Run the netq show opta-health command to verify all applications are operating properly. Please allow 10-15 minutes for all applications to come up and report their status.
If any of the applications or services display Status as DOWN after 30 minutes, open a support ticket and attach the output of the opta-support command.
Run the following commands on your master node, using the IP addresses of your worker nodes:
You can specify the IP address instead of the interface name here: use ip-addr <IP address> in place of interface eth0 above.
Run the netq show opta-health command to verify all applications are operating properly. Please allow 10-15 minutes for all applications to come up and report their status.
If any of the applications or services display Status as DOWN after 30 minutes, open a support ticket and attach the output of the opta-support command.
Run the following command on your NetQ Cloud Appliance with the config-key sent by Cumulus Networks in an email titled “A new site has been added to your Cumulus NetQ account.”
You can specify the IP address instead of the interface name here: use ip-addr <IP address> in place of interface eth0 above.
Run the netq show opta-health command to verify all applications are operating properly.
cumulus@hostname:~$ netq show opta-health
OPTA is healthy
Run the following commands on your master NetQ Cloud Appliance with the config-key sent by Cumulus Networks in an email titled “A new site has been added to your Cumulus NetQ account.”
After installing your Cumulus NetQ Platform or Collector software, the next step is to install NetQ switch software for all switches and host servers that you want to monitor in your network. This includes the NetQ Agent, and optionally the NetQ CLI. While the CLI is optional, it can be very useful to be able to access a switch or host through the command line for troubleshooting or device management. The telemetry data is sent by the NetQ Agent on a switch or host to your NetQ Platform or Collector on your NetQ On-premises or Cloud Appliance or VM.
Cumulus NetQ Agents can be installed on switches or hosts running Cumulus Linux, Ubuntu, Red Hat Enterprise, or CentOS operating systems (OSs). Install the NetQ Agent based on the OS:
Install and Configure the NetQ Agent on Cumulus Linux Switches
After installing your Cumulus NetQ software, you should install the NetQ 3.2.1 Agents on each switch you want to monitor. NetQ Agents can be installed on switches running:
Cumulus Linux version 3.3.2-3.7.x
Cumulus Linux version 4.0.0 and later
Prepare for NetQ Agent Installation on a Cumulus Linux Switch
For servers running Cumulus Linux, you need to:
Install and configure NTP, if needed
Obtain NetQ software packages
If your network uses a proxy server for external connections, you should first configure a global proxy so apt-get can access the software package in the Cumulus Networks repository.
Verify NTP is Installed and Configured
Verify that NTP is running on the switch. The switch must be in time synchronization with the NetQ Platform or NetQ Appliance to enable useful statistical analysis.
cumulus@switch:~$ sudo systemctl status ntp
[sudo] password for cumulus:
● ntp.service - LSB: Start NTP daemon
Loaded: loaded (/etc/init.d/ntp; bad; vendor preset: enabled)
Active: active (running) since Fri 2018-06-01 13:49:11 EDT; 2 weeks 6 days ago
Docs: man:systemd-sysv-generator(8)
CGroup: /system.slice/ntp.service
└─2873 /usr/sbin/ntpd -p /var/run/ntpd.pid -g -c /var/lib/ntp/ntp.conf.dhcp -u 109:114
If NTP is not installed, install and configure it before continuing.
If NTP is not running:
Verify the IP address or hostname of the NTP server in the /etc/ntp.conf file, and then
Reenable and start the NTP service using the systemctl [enable|start] ntp commands
If you are running NTP in your out-of-band management network with VRF, specify the VRF (ntp@<vrf-name> versus just ntp) in the above commands.
Obtain NetQ Agent Software Package
To install the NetQ Agent you need to install netq-agent on each switch or host. This is available from the Cumulus Networks repository.
To obtain the NetQ Agent package:
Edit the /etc/apt/sources.list file to add the repository for Cumulus NetQ.
Note that NetQ has a separate repository from Cumulus Linux.
cumulus@switch:~$ sudo nano /etc/apt/sources.list
...
deb http://apps3.cumulusnetworks.com/repos/deb CumulusLinux-3 netq-3.2
...
The repository deb http://apps3.cumulusnetworks.com/repos/deb CumulusLinux-3 netq-latest can be used if you want to always retrieve the latest posted version of NetQ.
Add the repository:
cumulus@switch:~$ sudo nano /etc/apt/sources.list
...
deb http://apps3.cumulusnetworks.com/repos/deb CumulusLinux-4 netq-3.2
...
The repository deb http://apps3.cumulusnetworks.com/repos/deb CumulusLinux-4 netq-latest can be used if you want to always retrieve the latest posted version of NetQ.
Add the apps3.cumulusnetworks.com authentication key to Cumulus Linux:
Continue with NetQ Agent configuration in the next section.
Configure the NetQ Agent on a Cumulus Linux Switch
After the NetQ Agent and CLI have been installed on the servers you want to monitor, the NetQ Agents must be configured to obtain useful and relevant data.
The NetQ Agent is aware of and communicates through the designated VRF. If you do not specify one, the default VRF (named default) is used. If you later change the VRF configured for the NetQ Agent (using a lifecycle management configuration profile, for example), you might cause the NetQ Agent to lose communication.
Two methods are available for configuring a NetQ Agent:
Edit the configuration file on the switch, or
Use the NetQ CLI
Configure NetQ Agents Using a Configuration File
You can configure the NetQ Agent in the netq.yml configuration file contained in the /etc/netq/ directory.
Open the netq.yml file using your text editor of choice. For example:
cumulus@switch:~$ sudo nano /etc/netq/netq.yml
Locate the netq-agent section, or add it.
Set the parameters for the agent as follows:
port: 31980 (default configuration)
server: IP address of the NetQ Appliance or VM where the agent should send its collected data
Configure Advanced NetQ Agent Settings on a Cumulus Linux Switch
A couple of additional options are available for configuring the NetQ Agent. If you are using VRF, you can configure the agent to communicate over a specific VRF. You can also configure the agent to use a particular port.
Configure the Agent to Use a VRF
While optional, Cumulus strongly recommends that you configure NetQ Agents to communicate with the NetQ Appliance or VM only via a VRF, including a management VRF. To do so, you need to specify the VRF name when configuring the NetQ Agent. For example, if the management VRF is configured and you want the agent to communicate with the NetQ Appliance or VM over it, configure the agent like this:
Configure the Agent to Communicate over a Specific Port
By default, NetQ uses port 31980 for communication between the NetQ Appliance or VM and NetQ Agents. If you want the NetQ Agent to communicate with the NetQ Appliance or VM via a different port, you need to specify the port number when configuring the NetQ Agent, like this:
cumulus@leaf01:~$ sudo netq config add agent server 192.168.1.254 port 7379
cumulus@leaf01:~$ sudo netq config restart agent
Install and Configure the NetQ Agent on Ubuntu Servers
After installing your Cumulus NetQ software, you should install the NetQ 3.2.1 Agent on each server you want to monitor. NetQ Agents can be installed on servers running:
Ubuntu 16.04
Ubuntu 18.04 (NetQ 2.2.2 and later)
Prepare for NetQ Agent Installation on an Ubuntu Server
For servers running Ubuntu OS, you need to:
Verify the minimum service packages versions are installed
Verify the server is running lldpd
Install and configure network time server, if needed
Obtain NetQ software packages
If your network uses a proxy server for external connections, you should first configure a global proxy so apt-get can access the agent package on the Cumulus Networks repository.
Verify Service Package Versions
Before you install the NetQ Agent on an Ubuntu server, make sure the
following packages are installed and running these minimum versions:
iproute 1:4.3.0-1ubuntu3.16.04.1 all
iproute2 4.3.0-1ubuntu3 amd64
lldpd 0.7.19-1 amd64
ntp 1:4.2.8p4+dfsg-3ubuntu5.6 amd64
Verify the Server is Running lldpd
Make sure you are running lldpd, not lldpad. Ubuntu does not include lldpd by default, which is required for the installation.
To install this package, run the following commands:
If NTP is not already installed and configured, follow these steps:
Install NTP on the server, if not already installed. Servers must be in time synchronization with the NetQ Platform or NetQ Appliance to enable useful statistical analysis.
root@ubuntu:~# sudo apt-get install ntp
Configure the network time server.
Open the /etc/ntp.conf file in your text editor of choice.
Under the Server section, specify the NTP server IP address or hostname.
Create the file /etc/apt/sources.list.d/cumulus-host-ubuntu-xenial.list and add the following line:
root@ubuntu:~# vi /etc/apt/sources.list.d/cumulus-apps-deb-xenial.list
...
deb [arch=amd64] https://apps3.cumulusnetworks.com/repos/deb xenial netq-latest
...
Create the file /etc/apt/sources.list.d/cumulus-host-ubuntu-bionic.list and add the following line:
root@ubuntu:~# vi /etc/apt/sources.list.d/cumulus-apps-deb-bionic.list
...
deb [arch=amd64] https://apps3.cumulusnetworks.com/repos/deb bionic netq-latest
...
The use of netq-latest in these examples means that a get to the repository always retrieves the latest version of NetQ, even in the case where a major version update has been made. If you want to keep the repository on a specific version - such as netq-3.1 - use that instead.
Install NetQ Agent on an Ubuntu Server
After completing the preparation steps, you can successfully install the agent software onto your server.
Continue with NetQ Agent Configuration in the next section.
Configure the NetQ Agent on an Ubuntu Server
After the NetQ Agent and CLI have been installed on the servers you want to monitor, the NetQ Agents must be configured to obtain useful and relevant data.

root@ubuntu:~# sudo netq config add agent server 192.168.1.254 port 7379
root@ubuntu:~# sudo netq config restart agent
Install and Configure the NetQ Agent on RHEL and CentOS Servers
After installing your Cumulus NetQ software, you should install the NetQ 3.2.1 Agents on each server you want to monitor. NetQ Agents can be installed on servers running:
Red Hat RHEL 7.1
CentOS 7
Prepare for NetQ Agent Installation on a RHEL or CentOS Server
For servers running RHEL or CentOS, you need to:
Verify the minimum package versions are installed
Verify the server is running lldpd
Install and configure NTP, if needed
Obtain NetQ software packages
If your network uses a proxy server for external connections, you should first configure a global proxy so apt-get can access the software package in the Cumulus Networks repository.
Verify Service Package Versions
Before you install the NetQ Agent on a Red Hat or CentOS server, make sure the following packages are installed and running these minimum versions:
iproute-3.10.0-54.el7_2.1.x86_64
lldpd-0.9.7-5.el7.x86_64
ntp-4.2.6p5-25.el7.centos.2.x86_64
ntpdate-4.2.6p5-25.el7.centos.2.x86_64
Verify the Server is Running lldpd and wget
Make sure you are running lldpd, not lldpad. CentOS does not include lldpd by default, nor does it include wget, which is required for the installation.
To install this package, run the following commands:
Restart rsyslog so log files are sent to the correct destination.
root@rhel7:~# sudo systemctl restart rsyslog
Continue with NetQ Agent Configuration in the next section.

Install NetQ CLI
When installing NetQ 3.2.x, it is not required that you install the NetQ CLI on your NetQ Appliances or VMs, or monitored switches and hosts, but it provides new features, important bug fixes, and the ability to manage your network from multiple points in the network.
Use the instructions in the following sections based on the OS installed on the switch or server:
Install and Configure the NetQ CLI on Cumulus Linux Switches
After installing your Cumulus NetQ software and the NetQ 3.2.1 Agent on each switch you want to monitor, you can also install the NetQ CLI on switches running:
Cumulus Linux version 3.3.2-3.7.x
Cumulus Linux version 4.0.0 and later
Install the NetQ CLI on a Cumulus Linux Switch
A simple process installs the NetQ CLI on a Cumulus Linux switch.
To install the NetQ CLI you need to install netq-apps on each switch. This is available from the Cumulus Networks repository.
If your network uses a proxy server for external connections, you should first configure a global proxy so apt-get can access the software package in the Cumulus Networks repository.
To obtain the NetQ Agent package:
Edit the /etc/apt/sources.list file to add the repository for Cumulus NetQ.
Note that NetQ has a separate repository from Cumulus Linux.
cumulus@switch:~$ sudo nano /etc/apt/sources.list
...
deb http://apps3.cumulusnetworks.com/repos/deb CumulusLinux-3 netq-3.2
...
The repository deb http://apps3.cumulusnetworks.com/repos/deb CumulusLinux-4 netq-latest can be used if you want to always retrieve the latest posted version of NetQ.
cumulus@switch:~$ sudo nano /etc/apt/sources.list
...
deb http://apps3.cumulusnetworks.com/repos/deb CumulusLinux-4 netq-3.2
...
The repository deb http://apps3.cumulusnetworks.com/repos/deb CumulusLinux-4 netq-latest can be used if you want to always retrieve the latest posted version of NetQ.
Update the local apt repository and install the software on the switch.
By default, the NetQ CLI is not configured during the NetQ installation. The configuration is stored in /etc/netq/netq.yml.
While the CLI is not configured, you can run only netq config commandsand netq help commands, and you must use sudo to run them.
At minimum, you need to configure the NetQ CLI and NetQ Agent to communicate with the telemetry server. To do so, configure the NetQ Agent and the NetQ CLI so that they are running in the VRF where the routing tables are set for connectivity to the telemetry server. Typically this is the management VRF.
To configure the NetQ CLI, run the following command, then restart the NetQ CLI. This example assumes the telemetry server is reachable via the IP address 10.0.1.1 over port 32000 and the management VRF (mgmt).
cumulus@switch:~$ sudo netq config add cli server 10.0.1.1 vrf mgmt port 32000
cumulus@switch:~$ sudo netq config restart cli
Restarting the CLI stops the current running instance of netqd and starts netqd in the specified VRF.
The steps to configure the CLI are different depending on whether the NetQ software has been installed for an on-premises or cloud deployment. Follow the instructions for your deployment type.
Use the following command to configure the CLI:
netq config add cli server <text-gateway-dest> [vrf <text-vrf-name>] [port <text-gateway-port>]
Restart the CLI afterward to activate the configuration.
This example uses an IP address of 192.168.1.0 and the default port and VRF.
If you have a server cluster deployed, use the IP address of the master server.
To access and configure the CLI on your NetQ Cloud Appliance or VM, you must have your username and password to access the NetQ UI to generate AuthKeys. These keys provide authorized access (access key) and user authentication (secret key). Your credentials and NetQ Cloud addresses were provided by Cumulus Networks via an email titled Welcome to Cumulus NetQ!
To generate AuthKeys:
In your Internet browser, enter netq.cumulusnetworks.com into the address field to open the NetQ UI login page.
Enter your username and password.
Click (Main Menu), select Management in the Admin column.
Click Manage on the User Accounts card.
Select your user and click above the table.
Copy these keys to a safe place.
The secret key is only shown once. If you do not copy these, you will need to regenerate them and reconfigure CLI access.
You can also save these keys to a YAML file for easy reference, and to avoid having to type or copy the key values. You can:
store the file wherever you like, for example in /home/cumulus/ or /etc/netq
name the file whatever you like, for example credentials.yml, creds.yml, or keys.yml
Restart the CLI afterward to activate the configuration.
This example uses the individual access key, a premises of datacenterwest, and the default Cloud address, port and VRF. Be sure to replace the key values with your generated keys if you are using this example on your server.

Restarting NetQ CLI... Success!
If you have multiple premises and want to query data from a different premises than you originally configured, rerun the netq config add cli server command with the desired premises name. You can only view the data for one premises at a time with the CLI.
Configure NetQ CLI Using a Configuration File
You can configure the NetQ CLI in the netq.yml configuration file contained in the /etc/netq/ directory.
Open the netq.yml file using your text editor of choice. For example:
cumulus@switch:~$ sudo nano /etc/netq/netq.yml
Locate the netq-cli section, or add it.
Set the parameters for the CLI.
Specify the following parameters:
netq-user: User who can access the CLI
server: IP address of the NetQ server or NetQ Appliance
port (default): 32708
Your YAML configuration file should be similar to this:
Install and Configure the NetQ CLI on Ubuntu Servers
After installing your Cumulus NetQ software, you should install the NetQ 3.2.1 Agents on each switch you want to monitor. NetQ Agents can be installed on servers running:
Ubuntu 16.04
Ubuntu 18.04 (NetQ 2.2.2 and later)
Prepare for NetQ CLI Installation on an Ubuntu Server
For servers running Ubuntu OS, you need to:
Verify the minimum service packages versions are installed
Verify the server is running lldpd
Install and configure network time server, if needed
Obtain NetQ software packages
If your network uses a proxy server for external connections, you should first configure a global proxy so apt-get can access the software package in the Cumulus Networks repository.
Verify Service Package Versions
Before you install the NetQ Agent on an Ubuntu server, make sure the
following packages are installed and running these minimum versions:
iproute 1:4.3.0-1ubuntu3.16.04.1 all
iproute2 4.3.0-1ubuntu3 amd64
lldpd 0.7.19-1 amd64
ntp 1:4.2.8p4+dfsg-3ubuntu5.6 amd64
Verify the Server is Running lldpd
Make sure you are running lldpd, not lldpad. Ubuntu does not include lldpd by default, which is required for the installation.
To install this package, run the following commands:
If NTP is not already installed and configured, follow these steps:
Install NTP on the server, if not already installed. Servers must be in time synchronization with the NetQ Platform or NetQ Appliance to enable useful statistical analysis.
root@ubuntu:~# sudo apt-get install ntp
Configure the network time server.
Open the /etc/ntp.conf file in your text editor of choice.
Under the Server section, specify the NTP server IP address or hostname.
Create the file /etc/apt/sources.list.d/cumulus-host-ubuntu-xenial.list and add the following line:
root@ubuntu:~# vi /etc/apt/sources.list.d/cumulus-apps-deb-xenial.list
...
deb [arch=amd64] https://apps3.cumulusnetworks.com/repos/deb xenial netq-latest
...
Create the file /etc/apt/sources.list.d/cumulus-host-ubuntu-bionic.list and add the following line:
root@ubuntu:~# vi /etc/apt/sources.list.d/cumulus-apps-deb-bionic.list
...
deb [arch=amd64] https://apps3.cumulusnetworks.com/repos/deb bionic netq-latest
...
The use of netq-latest in these examples means that a get to the repository always retrieves the latest version of NetQ, even in the case where a major version update has been made. If you want to keep the repository on a specific version - such as netq-3.1 - use that instead.
Install NetQ CLI on an Ubuntu Server
A simple process installs the NetQ CLI on an Ubuntu server.
By default, the NetQ CLI is not configured during the NetQ installation. The configuration is stored in /etc/netq/netq.yml.
While the CLI is not configured, you can run only netq config commandsand netq help commands, and you must use sudo to run them.
At minimum, you need to configure the NetQ CLI and NetQ Agent to communicate with the telemetry server. To do so, configure the NetQ Agent and the NetQ CLI so that they are running in the VRF where the routing tables are set for connectivity to the telemetry server. Typically this is the management VRF.
To configure the NetQ CLI, run the following command, then restart the NetQ CLI. This example assumes the telemetry server is reachable via the IP address 10.0.1.1 over port 32000 and the management VRF (mgmt).
root@host:~# sudo netq config add cli server 10.0.1.1 vrf mgmt port 32000
root@host:~# sudo netq config restart cli
Restarting the CLI stops the current running instance of netqd and starts netqd in the specified VRF.
The steps to configure the CLI are different depending on whether the NetQ software has been installed for an on-premises or cloud deployment. Follow the instruction for your deployment type.
Use the following command to configure the CLI:
netq config add cli server <text-gateway-dest> [vrf <text-vrf-name>] [port <text-gateway-port>]
Restart the CLI afterward to activate the configuration.
This example uses an IP address of 192.168.1.0 and the default port and VRF.
If you have a server cluster deployed, use the IP address of the master server.
To access and configure the CLI on your NetQ Platform or NetQ Cloud Appliance, you must have your username and password to access the NetQ UI to generate AuthKeys. These keys provide authorized access (access key) and user authentication (secret key). Your credentials and NetQ Cloud addresses were provided by Cumulus Networks via an email titled Welcome to Cumulus NetQ!
To generate AuthKeys:
In your Internet browser, enter netq.cumulusnetworks.com into the address field to open the NetQ UI login page.
Enter your username and password.
From the Main Menu, select Management in the Admin column.
Click Manage on the User Accounts card.
Select your user and click above the table.
Copy these keys to a safe place.
The secret key is only shown once. If you do not copy these, you will need to regenerate them and reconfigure CLI access.
You can also save these keys to a YAML file for easy reference, and to avoid having to type or copy the key values. You can:
store the file wherever you like, for example in /home/cumulus/ or /etc/netq
name the file whatever you like, for example credentials.yml, creds.yml, or keys.yml
Restart the CLI afterward to activate the configuration.
This example uses the individual access key, a premises of datacenterwest, and the default Cloud address, port and VRF. Be sure to replace the key values with your generated keys if you are using this example on your server.

Your YAML configuration file should be similar to this:
To collect network telemetry data, the NetQ Agents must be installed on the relevant switches and hosts. It is a time saving process to update the NetQ Agent and CLI at the same time, but is not required. It always recommended that the NetQ Agents be updated. The NetQ CLI is optional, but can be very useful.
Use the instructions in the following sections based on the OS installed on the switch or server to install both the NetQ Agent and the CLI at the same time.
Install and Configure the NetQ Agent and CLI on Cumulus Linux Switches
After installing your Cumulus NetQ software, you can install the NetQ 3.2.1 Agents and CLI on each switch you want to monitor. These can be installed on switches running:
Cumulus Linux version 3.3.2-3.7.x
Cumulus Linux version 4.0.0 and later
Prepare for NetQ Agent and CLI Installation on a Cumulus Linux Switch
For servers running Cumulus Linux, you need to:
Install and configure NTP, if needed
Obtain NetQ software packages
If your network uses a proxy server for external connections, you should first configure a global proxy so apt-get can access the software package in the Cumulus Networks repository.
Verify NTP is Installed and Configured
Verify that NTP is running on the switch. The switch must be in time synchronization with the NetQ Platform or NetQ Appliance to enable useful statistical analysis.
cumulus@switch:~$ sudo systemctl status ntp
[sudo] password for cumulus:
● ntp.service - LSB: Start NTP daemon
Loaded: loaded (/etc/init.d/ntp; bad; vendor preset: enabled)
Active: active (running) since Fri 2018-06-01 13:49:11 EDT; 2 weeks 6 days ago

└─2873 /usr/sbin/ntpd -p /var/run/ntpd.pid -g -c /var/lib/ntp/ntp.conf.dhcp -u 109:114
If NTP is not installed, install and configure it before continuing.
If NTP is not running:
Verify the IP address or hostname of the NTP server in the /etc/ntp.conf file, and then
Reenable and start the NTP service using the systemctl [enable|start] ntp commands
If you are running NTP in your out-of-band management network with VRF, specify the VRF (ntp@<vrf-name> versus just ntp) in the above commands.
Obtain NetQ Agent and CLI Software Packages
To install the NetQ Agent you need to install netq-agent on each switch or host. To install the NetQ CLI you need to install netq-apps on each switch. These are available from the Cumulus Networks repository.
To obtain the NetQ packages:
Edit the /etc/apt/sources.list file to add the repository for Cumulus NetQ.
Note that NetQ has a separate repository from Cumulus Linux.
cumulus@switch:~$ sudo nano /etc/apt/sources.list
...
deb http://apps3.cumulusnetworks.com/repos/deb CumulusLinux-3 netq-3.2
...
The repository deb http://apps3.cumulusnetworks.com/repos/deb CumulusLinux-3 netq-latest can be used if you want to always retrieve the latest posted version of NetQ.
Add the repository:
cumulus@switch:~$ sudo nano /etc/apt/sources.list
...
deb http://apps3.cumulusnetworks.com/repos/deb CumulusLinux-4 netq-3.2
...
The repository deb http://apps3.cumulusnetworks.com/repos/deb CumulusLinux-4 netq-latest can be used if you want to always retrieve the latest posted version of NetQ.
Add the apps3.cumulusnetworks.com authentication key to Cumulus Linux:
Continue with NetQ Agent and CLI configuration in the next section.
Configure the NetQ Agent and CLI on a Cumulus Linux Switch
After the NetQ Agent and CLI have been installed on the servers you want to monitor, the NetQ Agents must be configured to obtain useful and relevant data.
The NetQ Agent is aware of and communicates through the designated VRF. If you do not specify one, the default VRF (named default) is used. If you later change the VRF configured for the NetQ Agent (using a lifecycle management configuration profile, for example), you might cause the NetQ Agent to lose communication.
Two methods are available for configuring a NetQ Agent:
Edit the configuration file on the switch, or
Use the NetQ CLI
Configure NetQ Agent and CLI Using a Configuration File
You can configure the NetQ Agent and CLI in the netq.yml configuration file contained in the /etc/netq/ directory.
Open the netq.yml file using your text editor of choice. For example:
cumulus@switch:~$ sudo nano /etc/netq/netq.yml
Locate the netq-agent section, or add it.
Set the parameters for the agent as follows:
port: 31980 (default configuration)
server: IP address of the NetQ Appliance or VM where the agent should send its collected data
The steps to configure the CLI are different depending on whether the NetQ software has been installed for an on-premises or cloud deployment. Follow the instructions for your deployment type.
Use the following command to configure the CLI:
netq config add cli server <text-gateway-dest> [vrf <text-vrf-name>] [port <text-gateway-port>]
Restart the CLI afterward to activate the configuration.
This example uses an IP address of 192.168.1.0 and the default port and VRF.
If you have a server cluster deployed, use the IP address of the master server.
To access and configure the CLI on your NetQ Cloud Appliance or VM, you must have your username and password to access the NetQ UI to generate AuthKeys. These keys provide authorized access (access key) and user authentication (secret key). Your credentials and NetQ Cloud addresses were provided by Cumulus Networks via an email titled Welcome to Cumulus NetQ!
To generate AuthKeys:
In your Internet browser, enter netq.cumulusnetworks.com into the address field to open the NetQ UI login page.
Enter your username and password.
Click (Main Menu), select Management in the Admin column.
Click Manage on the User Accounts card.
Select your user and click above the table.
Copy these keys to a safe place.
The secret key is only shown once. If you do not copy these, you will need to regenerate them and reconfigure CLI access.
You can also save these keys to a YAML file for easy reference, and to avoid having to type or copy the key values. You can:
store the file wherever you like, for example in /home/cumulus/ or /etc/netq
name the file whatever you like, for example credentials.yml, creds.yml, or keys.yml
Restart the CLI afterward to activate the configuration.
This example uses the individual access key, a premises of datacenterwest, and the default Cloud address, port and VRF. Be sure to replace the key values with your generated keys if you are using this example on your server.

If you have multiple premises and want to query data from a different premises than you originally configured, rerun the netq config add cli server command with the desired premises name. You can only view the data for one premises at a time with the CLI.
Configure Advanced NetQ Agent Settings on a Cumulus Linux Switch
A couple of additional options are available for configuring the NetQ Agent. If you are using VRF, you can configure the agent to communicate over a specific VRF. You can also configure the agent to use a particular port.
Configure the Agent to Use a VRF
While optional, Cumulus strongly recommends that you configure NetQ Agents to communicate with the NetQ Appliance or VM only via a VRF, including a management VRF. To do so, you need to specify the VRF name when configuring the NetQ Agent. For example, if the management VRF is configured and you want the agent to communicate with the NetQ Appliance or VM over it, configure the agent like this:
Configure the Agent to Communicate over a Specific Port
By default, NetQ uses port 31980 for communication between the NetQ Appliance or VM and NetQ Agents. If you want the NetQ Agent to communicate with the NetQ Appliance or VM via a different port, you need to specify the port number when configuring the NetQ Agent, like this:
cumulus@leaf01:~$ sudo netq config add agent server 192.168.1.254 port 7379
cumulus@leaf01:~$ sudo netq config restart agent
Install and Configure the NetQ Agent and CLI on Ubuntu Servers
After installing your Cumulus NetQ software, you should install the NetQ 3.2.1 Agent on each server you want to monitor. NetQ Agents can be installed on servers running:
Ubuntu 16.04
Ubuntu 18.04 (NetQ 2.2.2 and later)
Prepare for NetQ Agent Installation on an Ubuntu Server
For servers running Ubuntu OS, you need to:
Verify the minimum service packages versions are installed
Verify the server is running lldpd
Install and configure network time server, if needed
Obtain NetQ software packages
If your network uses a proxy server for external connections, you should first configure a global proxy so apt-get can access the agent package on the Cumulus Networks repository.
Verify Service Package Versions
Before you install the NetQ Agent on an Ubuntu server, make sure the
following packages are installed and running these minimum versions:
iproute 1:4.3.0-1ubuntu3.16.04.1 all
iproute2 4.3.0-1ubuntu3 amd64
lldpd 0.7.19-1 amd64
ntp 1:4.2.8p4+dfsg-3ubuntu5.6 amd64
Verify the Server is Running lldpd
Make sure you are running lldpd, not lldpad. Ubuntu does not include lldpd by default, which is required for the installation.
To install this package, run the following commands:
If NTP is not already installed and configured, follow these steps:
Install NTP on the server, if not already installed. Servers must be in time synchronization with the NetQ Platform or NetQ Appliance to enable useful statistical analysis.
root@ubuntu:~# sudo apt-get install ntp
Configure the network time server.
Open the /etc/ntp.conf file in your text editor of choice.
Under the Server section, specify the NTP server IP address or hostname.
Create the file /etc/apt/sources.list.d/cumulus-host-ubuntu-xenial.list and add the following line:
root@ubuntu:~# vi /etc/apt/sources.list.d/cumulus-apps-deb-xenial.list
...
deb [arch=amd64] https://apps3.cumulusnetworks.com/repos/deb xenial netq-latest

Create the file /etc/apt/sources.list.d/cumulus-host-ubuntu-bionic.list and add the following line:
root@ubuntu:~# vi /etc/apt/sources.list.d/cumulus-apps-deb-bionic.list
...
deb [arch=amd64] https://apps3.cumulusnetworks.com/repos/deb bionic netq-latest
...
The use of netq-latest in these examples means that a get to the repository always retrieves the latest version of NetQ, even in the case where a major version update has been made. If you want to keep the repository on a specific version - such as netq-2.4 - use that instead.
Install NetQ Agent on an Ubuntu Server
After completing the preparation steps, you can successfully install the agent software onto your server.

For example, if the management VRF is configured and you want the agent to communicate with the NetQ Platform over it, configure the agent like this:
Configure the NetQ Agent to Communicate over a Specific Port
By default, NetQ uses port 31980 for communication between the NetQ Platform and NetQ Agents. If you want the NetQ Agent to communicate with the NetQ Platform via a different port, you need to specify the port number when configuring the NetQ Agent like this:
root@ubuntu:~# sudo netq config add agent server 192.168.1.254 port 7379
root@ubuntu:~# sudo netq config restart agent
Install and Configure the NetQ Agent and CLI on RHEL and CentOS Servers
After installing your Cumulus NetQ software, you can install the NetQ 3.2.1 Agent and CLI on each server you want to monitor. These can be installed on servers running:
Red Hat RHEL 7.1
CentOS 7
Prepare for NetQ Agent and CLI Installation on a RHEL or CentOS Server
For servers running RHEL or CentOS, you need to:
Verify the minimum package versions are installed
Verify the server is running lldpd
Install and configure NTP, if needed
Obtain NetQ software packages
If your network uses a proxy server for external connections, you should first configure a global proxy so apt-get can access the software package in the Cumulus Networks repository.
Verify Service Package Versions
Before you install the NetQ Agent and CLI on a Red Hat or CentOS server, make sure the following packages are installed and running these minimum versions:
iproute-3.10.0-54.el7_2.1.x86_64
lldpd-0.9.7-5.el7.x86_64
ntp-4.2.6p5-25.el7.centos.2.x86_64
ntpdate-4.2.6p5-25.el7.centos.2.x86_64
Verify the Server is Running lldpd and wget
Make sure you are running lldpd, not lldpad. CentOS does not include lldpd by default, nor does it include wget, which is required for the installation.
To install this package, run the following commands:
If you are running NTP in your out-of-band management network with VRF, specify the VRF (ntp@<vrf-name> versus just ntp) in the above commands.
Verify NTP is operating correctly. Look for an asterisk (*) or a plus sign (+) that indicates the clock is synchronized.

Obtain NetQ Agent and CLI Package
To install the NetQ Agent you need to install netq-agent on each switch or host. To install the NetQ CLI you need to install netq-apps on each switch or host. These are available from the Cumulus Networks repository.
Restart rsyslog so log files are sent to the correct destination.
root@rhel7:~# sudo systemctl restart rsyslog
Continue with NetQ Agent and CLI Configuration in the next section.
Configure the NetQ Agent and CLI on a RHEL or CentOS Server
After the NetQ Agent and CLI have been installed on the servers you want to monitor, the NetQ Agents must be configured to obtain useful and relevant data.
The NetQ Agent is aware of and communicates through the designated VRF. If you do not specify one, the default VRF (named default) is used. If you later change the VRF configured for the NetQ Agent (using a lifecycle management configuration profile, for example), you might cause the NetQ Agent to lose communication.
Two methods are available for configuring a NetQ Agent:
Edit the configuration file on the device, or
Use the NetQ CLI.
Configure the NetQ Agents Using a Configuration File
You can configure the NetQ Agent and CLI in the netq.yml configuration file contained in the /etc/netq/ directory.
Open the netq.yml file using your text editor of choice. For example:
root@rhel7:~# sudo nano /etc/netq/netq.yml
Locate the netq-agent section, or add it.
Set the parameters for the agent as follows:
port: 31980 (default) or one that you specify
server: IP address of the NetQ server or appliance where the agent should send its collected data
The steps to configure the CLI are different depending on whether the NetQ software has been installed for an on-premises or cloud deployment. Follow the instructions for your deployment type.
Use the following command to configure the CLI:
netq config add cli server <text-gateway-dest> [vrf <text-vrf-name>] [port <text-gateway-port>]
Restart the CLI afterward to activate the configuration.
This example uses an IP address of 192.168.1.0 and the default port and VRF.
If you have a server cluster deployed, use the IP address of the master server.
To access and configure the CLI on your NetQ Platform or NetQ Cloud Appliance, you must have your username and password to access the NetQ UI to generate AuthKeys. These keys provide authorized access (access key) and user authentication (secret key). Your credentials and NetQ Cloud addresses were provided by Cumulus Networks via an email titled Welcome to Cumulus NetQ!
To generate AuthKeys:
In your Internet browser, enter netq.cumulusnetworks.com into the address field to open the NetQ UI login page.
Enter your username and password.
From the Main Menu, select Management in the Admin column.
Click Manage on the User Accounts card.
Select your user and click above the table.
Copy these keys to a safe place.
The secret key is only shown once. If you do not copy these, you will need to regenerate them and reconfigure CLI access.
You can also save these keys to a YAML file for easy reference, and to avoid having to type or copy the key values. You can:
store the file wherever you like, for example in /home/cumulus/ or /etc/netq
name the file whatever you like, for example credentials.yml, creds.yml, or keys.yml
Restart the CLI afterward to activate the configuration.
This example uses the individual access key, a premises of datacenterwest, and the default Cloud address, port and VRF. Be sure to replace the key values with your generated keys if you are using this example on your server.
root@rhel7:~# sudo netq config add cli server api.netq.cumulusnetworks.com access-key 123452d9bc2850a1726f55534279dd3c8b3ec55e8b25144d4739dfddabe8149e secret-key /vAGywae2E4xVZg8F+HtS6h6yHliZbBP6HXU3J98765= premises datacenterwest
Successfully logged into NetQ cloud at api.netq.cumulusnetworks.com:443
Updated cli server api.netq.cumulusnetworks.com vrf default port 443. Please restart netqd (netq config restart cli)
root@rhel7:~# sudo netq config restart cli
Restarting NetQ CLI... Success!
This example uses an optional keys file. Be sure to replace the keys filename and path with the full path and name of your keys file, and the datacenterwest premises name with your premises name if you are using this example on your server.
root@rhel7:~# sudo netq config add cli server api.netq.cumulusnetworks.com cli-keys-file /home/netq/nq-cld-creds.yml premises datacenterwest
Successfully logged into NetQ cloud at api.netq.cumulusnetworks.com:443
Updated cli server api.netq.cumulusnetworks.com vrf default port 443. Please restart netqd (netq config restart cli)
root@rhel7:~# sudo netq config restart cli
Restarting NetQ CLI... Success!
Rerun this command if you have multiple premises and want to query a different premises.
Configure Advanced NetQ Agent Settings
A couple of additional options are available for configuring the NetQ Agent. If you are using VRF, you can configure the agent to communicate over a specific VRF. You can also configure the agent to use a particular port.
Configure the NetQ Agent to Use a VRF
While optional, Cumulus strongly recommends that you configure NetQ Agents to communicate with the NetQ Platform only via a VRF, including a management VRF. To do so, you need to specify the VRF name when configuring the NetQ Agent. For example, if the management VRF is configured and you want the agent to communicate with the NetQ Platform over it, configure the agent like this:
Configure the NetQ Agent to Communicate over a Specific Port
By default, NetQ uses port 31980 for communication between the NetQ Platform and NetQ Agents. If you want the NetQ Agent to communicate with the NetQ Platform via a different port, you need to specify the port number when configuring the NetQ Agent like this:
root@rhel7:~# sudo netq config add agent server 192.168.1.254 port 7379
root@rhel7:~# sudo netq config restart agent
Upgrade NetQ
This topic describes how to upgrade from your current NetQ 2.4.1-3.2.0 installation to the NetQ 3.2.1 release to take advantage of new capabilities and bug fixes (refer to the release notes).
You must upgrade your NetQ On-premises or Cloud Appliance(s) or Virtual Machines (VMs). While NetQ 2.x Agents are compatible with NetQ 3.x, upgrading NetQ Agents is always recommended. If you want access to new and updated commands, you can upgrade the CLI on your physical servers or VMs, and monitored switches and hosts as well.
To complete the upgrade for either an on-premises or a cloud deployment:
The first step in upgrading your NetQ 2.4.1 - 3.2.0 installation to NetQ 3.2.1 is to upgrade your NetQ appliance(s) or VM(s). This topic describes how to upgrade this for both on-premises and cloud deployments.
Prepare for Upgrade
Three important steps are required to prepare for upgrade of your NetQ Platform:
Download the necessary software tarballs
Update the Debian packages on physical server and VMs
For Cloud VM deployments, increase the root volume disk image size
Optionally, you can choose to back up your NetQ Data before performing the upgrade.
To complete the preparation:
For on-premises deployments only, optionally back up your NetQ data. Refer to Back Up and Restore NetQ.
Select 3.2 from the Version list, and then click 3.2.1 in the submenu.
Select the relevant software from the HyperVisor/Platform list:
If you are upgrading NetQ Platform software for a NetQ On-premises Appliance or VM, select Appliance to download the NetQ-3.2.1.tgz file. If you are upgrading NetQ Collector software for a NetQ Cloud Appliance or VM, select Appliance (Cloud) to download the NetQ-3.2.1-opta.tgz file.
Scroll down and click Download on the on-premises or cloud NetQ Appliance image.
You can ignore the note on the image card because, unlike during installation, you do not need to download the bootstrap file for an upgrade.
Copy the file to the /mnt/installables/ directory on your appliance or VM.
Update /etc/apt/sources.list.d/cumulus-netq.list to netq-3.2 as follows:
cat /etc/apt/sources.list.d/cumulus-netq.list
deb [arch=amd64] https://apps3.cumulusnetworks.com/repos/deb bionic netq-3.2

If you are upgrading NetQ as a VM in the cloud from version 3.1.0 or earlier, you must increase the root volume disk image size for proper operation of the lifecycle management feature.
Check the size of the existing disk in the VM to confirm it is 32 GB. In this example, the number of 1 MB blocks is 31583, or 32 GB.
cumulus@netq-310-cloud:~$ df -hm /

Shutting down VMware VM using Shut down button in ESX
After the VM is shutdown (Shut down button is grayed out), click Edit.
In the Edit settings > Virtual Hardware > Hard disk field, change the 32 to 64 on the server hosting the VM.
Click Save.
Start the VM, log back in.
From step 1 we know the name of the root disk is /dev/sda1. Use that to run the following commands on the partition.
cumulus@netq-310-cloud:~$ sudo growpart /dev/sda 1

You can now upgrade your appliance using the NetQ Admin UI, in the next section. Alternately, you can upgrade using the CLI here: Upgrade Your Platform Using the NetQ CLI.
Upgrade Your Platform Using the NetQ Admin UI
After completing the preparation steps, upgrading your NetQ On-premises or Cloud Appliance(s) or VMs is simple using the Admin UI.
To upgrade your NetQ software:
Run the bootstrap CLI to upgrade the Admin UI application.
Cumulus Networks strongly recommends that you upgrade your NetQ Agents when you install or upgrade to a new release. If you are using NetQ Agent 2.4.0 update 24 or earlier, you must upgrade to ensure proper operation.
Upgrade NetQ Agents on Cumulus Linux Switches
The following instructions are applicable to both Cumulus Linux 3.x and 4.x, and for both on-premises and cloud deployments.
The following instructions are applicable to both NetQ Platform and NetQ Appliances running Ubuntu 16.04 or 18.04 in on-premises and cloud deployments.
While it is not required to upgrade the NetQ CLI on your monitored switches and hosts when you upgrade to NetQ 3.2.1, doing so gives you access to new features and important bug fixes. Refer to the release notes for details.
The following instructions are applicable to both NetQ Platform and NetQ Appliances running Ubuntu 16.04 or 18.04 in on-premises and cloud deployments.
It is recommended that you back up your NetQ data according to your company policy. Typically this includes after key configuration changes and on a scheduled basis.
These topics describe how to backup and also restore your NetQ data for NetQ On-premises Appliance and VMs.
These procedures do not apply to your NetQ Cloud Appliance or VM. Data backup is handled automatically with the NetQ cloud service.
Back Up Your NetQ Data
NetQ data is stored in a Cassandra database. A backup is performed by running scripts provided with the software and located in the /usr/sbin directory. When a backup is performed, a single tar file is created. The file is stored on a local drive that you specify and is named netq_master_snapshot_<timestamp>.tar.gz. Currently, only one backup file is supported, and includes the entire set of data tables. It is replaced each time a new backup is created.
If the rollback option is selected during the lifecycle management upgrade process (the default behavior), a backup is created automatically.
To manually create a backup:
If you are backing up data from NetQ 2.4.0 or earlier, or you upgraded from NetQ 2.4.0 to 2.4.1, obtain an updated backuprestore script. If you installed NetQ 2.4.1 as a fresh install, you can skip this step. Replace <version> in these commands with 2.4.1 or later release version.
cumulus@switch:~$ tar -xvzf /mnt/installables/NetQ-<version>.tgz -C /tmp/ ./netq-deploy-<version>.tgz
cumulus@switch:~$ tar -xvzf /tmp/netq-deploy-<version>.tgz -C /usr/sbin/ --strip-components 1 --wildcards backuprestore/*.sh
Run the backup script to create a backup file in /opt/<backup-directory> being sure to replace the backup-directory option with the name of the directory you want to use for the backup file.
You can abbreviate the backup and localdir options of this command to -b and -l to reduce typing. If the backup directory identified does not already exist, the script creates the directory during the backup process.
This is a sample of what you see as the script is running:

Verify the backup file has been created.
cumulus@switch:~$ cd /opt/<backup-directory>
cumulus@switch:~/opt/<backup-directory># ls
netq_master_snapshot_2019-06-04_07_24_50_UTC.tar.gz
To create a scheduled backup, add ./backuprestore.sh --backup --localdir /opt/<backup-directory> to an existing cron job, or create a new one.
Restore Your NetQ Data
You can restore NetQ data using the backup file you created above in Back Up and Restore NetQ. You can restore your instance to the same NetQ Platform or NetQ Appliance or to a new platform or appliance. You do not need to stop the server where the backup file resides to perform the restoration, but logins to the NetQ UI will fail during the restoration process.The restore option of the backup script, copies the data from the backup file to the database, decompresses it, verifies the restoration, and starts all necessary services. You should not see any data loss as a result of a restore operation.
To restore NetQ on the same hardware where the backup file resides:
If you are restoring data from NetQ 2.4.0 or earlier, or you upgraded from NetQ 2.4.0 to 2.4.1, obtain an updated backuprestore script. If you installed NetQ 2.4.1 as a fresh install, you can skip this step. Replace <version> in these commands with 2.4.1 or later release version.
cumulus@switch:~$ tar -xvzf /mnt/installables/NetQ-<version>.tgz -C /tmp/ ./netq-deploy-<version>.tgz
cumulus@switch:~$ tar -xvzf /tmp/netq-deploy-<version>.tgz -C /usr/sbin/ --strip-components 1 --wildcards backuprestore/*.sh
Run the restore script being sure to replace the backup-directory option with the name of the directory where the backup file resides.
You can abbreviate the restore and localdir options of this command to -r and -l to reduce typing.
This is a sample of what you see while the script is running:
[Fri 26 Jul 2019 02:37:49 PM UTC] - Received Inputs for restore ...

To restore NetQ on new hardware:
Copy the backup file from /opt/<backup-directory> on the older hardware to the backup directory on the new hardware.
Run the restore script on the new hardware, being sure to replace the backup-directory option with the name of the directory where the backup file resides.
After you have completed the installation of Cumulus NetQ,
you may want to configure some of the additional capabilities that NetQ
offers or integrate it with third-party software or hardware.
This topic describes how to:
Integrate with your LDAP server to use existing user accounts in NetQ
Integrate with Grafana to view interface statistics graphically
Integrate NetQ with Your LDAP Server
With this release and an administrator role, you are able to integrate the NetQ role-based access control (RBAC) with your lightweight directory access protocol (LDAP) server in on-premises deployments. NetQ maintains control over role-based permissions for the NetQ application. Currently there are two roles, admin and user. With the integration, user authentication is handled through LDAP and your directory service, such as Microsoft Active Directory, Kerberos, OpenLDAP, and Red Hat Directory Service. A copy of each user from LDAP is stored in the local NetQ database.
Integrating with an LDAP server does not prevent you from configuring local users (stored and managed in the NetQ database) as well.
Read Get Started to become familiar with LDAP configuration parameters, or skip to Create an LDAP Configuration if you are already an LDAP expert.
Get Started
LDAP integration requires information about how to connect to your LDAP server, the type of authentication you plan to use, bind credentials, and, optionally, search attributes.
Provide Your LDAP Server Information
To connect to your LDAP server, you need the URI and bind credentials. The URI identifies the location of the LDAP server. It is comprised of a FQDN (fully qualified domain name) or IP address, and the port of the LDAP server where the LDAP client can connect. For example: myldap.mycompany.com or 192.168.10.2. Typically port 389 is used for connection over TCP or UDP. In production environments, a secure connection with SSL can be deployed. In this case, the port used is typically 636. Setting the Enable SSL toggle automatically sets the server port to 636.
Specify Your Authentication Method
Two methods of user authentication are available: anonymous and basic.
Anonymous: LDAP client does not require any authentication. The user can access all resources anonymously. This is not commonly used for production environments.
Basic: (Also called Simple) LDAP client must provide a bind DN and password to authenticate the connection. When selected, the Admin credentials appear: Bind DN and Bind Password. The distinguished name (DN) is defined using a string of variables. Some common variables include:
Syntax
Description or Usage
cn
Common name
ou
Organizational unit or group
dc
Domain name
dc
Domain extension
Bind DN: DN of user with administrator access to query the LDAP server; used for binding with the server. For example, uid =admin,ou=ntwkops,dc=mycompany,dc=com.
Bind Password: Password associated with Bind DN.
The Bind DN and password are sent as clear text. Only users with these credentials are allowed to perform LDAP operations.
If you are unfamiliar with the configuration of your LDAP server, contact your administrator to ensure you select the appropriate authentication method and credentials.
Define User Attributes
Two attributes are required to define a user entry in a directory:
Base DN: Location in directory structure where search begins. For example, dc=mycompany,dc=com.
User ID: Type of identifier used to specify an LDAP user. This can vary depending on the authentication service you are using. For example, user ID (UID) or email address can be used with OpenLDAP, whereas sAMAccountName might be used with Active Directory.
Optionally, you can specify the first name, last name, and email address of the user.
Set Search Attributes
While optional, specifying search scope indicates where to start and how deep a given user can search within the directory. The data to search for is specified in the search query.
Search scope options include:
Subtree: Search for users from base, subordinates at any depth (default)
Base: Search for users at the base level only; no subordinates
One Level: Search for immediate children of user; not at base or for any descendants
Subordinate: Search for subordinates at any depth of user; but not at base
A typical search query for users would be {userIdAttribute}={userId}.
Now that you are familiar with the various LDAP configuration parameters, you can configure the integration of your LDAP server with NetQ using the instructions in the next section.
Create an LDAP Configuration
One LDAP server can be configured per bind DN (distinguished name). Once LDAP is configured, you can validate the connectivity (and configuration) and save the configuration.
To create an LDAP configuration:
Click , then select Management under Admin.
Locate the LDAP Server Info card, and click Configure LDAP.
Fill out the LDAP Server Configuration form according to your particular configuration. Refer to Overview for details about the various parameters.
Note: Items with an asterisk (*) are required. All others are optional.
Click Save to complete the configuration, or click Cancel to discard the configuration.
LDAP config cannot be changed once configured. If you need to change the configuration, you must delete the current LDAP configuration and create a new one. Note that if you change the LDAP server configuration, all users created against that LDAP server remain in the NetQ database and continue to be visible, but are no longer viable. You must manually delete those users if you do not want to see them.

Add LDAP Users to NetQ
Click , then select Management under Admin.
Locate the User Accounts card, and click Manage.
On the User Accounts tab, click Add User.
Select LDAP User.
Enter the user’s ID.
Enter your administrator password.
Click Search.
If the user is found, the email address, first and last name fields are automatically filled in on the Add New User form. If searching is not enabled on the LDAP server, you must enter the information manually.
If the fields are not automatically filled in, and searching is enabled on the LDAP server, you might require changes to the mapping file.
Select the NetQ user role for this user, admin or user, in the User Type dropdown.
Enter your admin password, and click Save, or click Cancel to discard the user account.
LDAP user passwords are not stored in the NetQ database and are always authenticated against LDAP.
Repeat these steps to add additional LDAP users.
Remove LDAP Users from NetQ
You can remove LDAP users in the same manner as local users.
Click , then select Management under Admin.
Locate the User Accounts card, and click Manage.
Select the user or users you want to remove.
Click in the Edit menu.
If an LDAP user is deleted in LDAP it is not automatically deleted from NetQ; however, the login credentials for these LDAP users stop working immediately.
Integrate NetQ with Grafana
Switches collect statistics about the performance of their interfaces. The NetQ Agent on each switch collects these statistics every 15 seconds and then sends them to your NetQ Appliance or Virtual Machine.
NetQ collects statistics for physical interfaces; it does not collect statistics for virtual interfaces, such as bonds, bridges, and VXLANs. NetQ collects these statistics from two data sources: Net-Q and Net-Q-Ethtool.
Net-Q displays:
Transmit with tx_ prefix: bytes, carrier, colls, drop, errs, packets
Receive with rx_ prefix: bytes, drop, errs, frame, multicast, packets
Software Transmit with soft_out_ prefix: errors, drops, tx_fifo_full
Software Receive with soft_in_ prefix: errors, frame_errors, drops
You can use Grafana version 6.x, an open source analytics and monitoring tool, to view these statistics. The fastest way to achieve this is by installing Grafana on an application server or locally per user, and then installing the NetQ plugin containing the prepared NetQ dashboard.
If you do not have Grafana installed already, refer to grafana.com for instructions on installing and configuring the Grafana tool.
Install NetQ Plugin for Grafana
Use the Grafana CLI to install the NetQ plugin. For more detail about this command, refer to the Grafana CLI documentation.
The quickest way to view the interface statistics for your Cumulus Linux network is to make use of the pre-configured dashboard installed with the plugin. Once you are familiar with that dashboard, you can create new dashboards or add new panels to the NetQ dashboard.
Open the Grafana user interface.
Log in using your application credentials.
The Home Dashboard appears.
Click Add data source or > Data Sources.
Enter Net-Q or Net-Q-Ethtool in the search box. Alternately, scroll down to the Other category, and select one of these sources from there.
You can create a dashboard with only the statistics of interest to you.
To create your own dashboard:
Click to open a blank dashboard.
Click (Dashboard Settings) at the top of the dashboard.
Click Variables.
Enter hostname into the Name field.
Enter Hostname into the Label field.
Select Net-Q or Net-Q-Ethtool from the Data source list.
Enter hostname into the Query field.
Click Add.
You should see a preview at the bottom of the hostname values.
Click to return to the new dashboard.
Click Add Query.
Select Net-Q or Net-Q-Ethtool from the Query source list.
Select the interface statistic you want to view from the Metric list.
Click the General icon.
Select hostname from the Repeat list.
Set any other parameters around how to display the data.
Return to the dashboard.
Add additional panels with other metrics to complete your dashboard.
Analyze the Data
Once you have your dashboard configured, you can start analyzing the data:
Select the hostname from the variable list at the top left of the charts to see the statistics for that switch or host.
Review the statistics, looking for peaks and valleys, unusual patterns, and so forth.
Explore the data more by modifying the data view in one of several ways using the dashboard tool set:
Select a different time period for the data by clicking the forward or back arrows. The default time range is dependent on the width of your browser window.
Zoom in on the dashboard by clicking the magnifying glass.
Manually refresh the dashboard data, or set an automatic refresh rate for the dashboard from the down arrow.
Add a new variable by clicking the cog wheel, then selecting Variables
Add additional panels
Click any chart title to edit or remove it from the dashboard
Rename the dashboard by clicking the cog wheel and entering the new name

Now that you know which events are supported and how to set the scope, you can create a basic rule to deliver one of the TCA events to a notification channel.
To create a TCA rule:
Click to open the Main Menu.
Click Threshold Crossing Rules under Notifications.
Click to add a rule.
The Create TCA Rule dialog opens. Four steps create the rule.
You can move forward and backward until you are satisfied with your rule definition.
On the Enter Details step, enter a name for your rule, choose your TCA event type, and assign a severity.
The rule name has a maximum of 20 characters (including spaces).
Click Next.
On the Choose Event step, select the attribute to measure against.
The attributes presented depend on the event type chosen in the Enter Details step. This example shows the attributes available when Resource Utilization was selected.
Click Next.
On the Set Threshold step, enter a threshold value.
Define the scope of the rule.
If you want to restrict the rule to a particular device, and enter values for one or more of the available parameters.
If you want the rule to apply to all devices, click the scope toggle.
Click Next.
Optionally, select a notification channel where you want the events to be sent. If no channel is select, the notifications are only available from the database. You can add a channel at a later time. Refer to Modify TCA Rules.
Click Finish.
This example shows two rules. The rule on the left triggers an informational event when switch leaf01 exceeds the maximum CPU utilization of 87%. The rule on the right triggers a critical event when any device exceeds the maximum CPU utilization of 93%. Note that the cards indicate both rules are currently Active.
View All TCA Rules
You can view all of the threshold-crossing event rules you have created by clicking and then selecting Threshold Crossing Rules under Notifications.
Modify TCA Rules
You can modify the threshold value and scope of any existing rules.
To edit a rule:
Click to open the Main Menu.
Click Threshold Crossing Rules under Notifications.
Locate the rule you want to modify and hover over the card.
Click .
Modify the rule, changing the threshold, scope or associated channel.
If you want to modify the rule name or severity after creating the rule, you must delete the rule and recreate it.
Click Update Rule.
Manage TCA Rules
Once you have created a bunch of rules, you might have the need to manage them; suppress a rule, disable a rule, or delete a rule.
Rule States
The TCA rules have three possible states:
Active: Rule is operating, delivering events. This would be the normal operating state.
Suppressed: Rule is disabled until a designated date and time. When that time occurs, the rule is automatically reenabled. This state is useful during troubleshooting or maintenance of a switch when you do not want erroneous events being generated.
Disabled: Rule is disabled until a user manually reenables it. This state is useful when you are unclear when you want the rule to be reenabled. This is not the same as deleting the rule.
Suppress a Rule
To suppress a rule for a designated amount of time, you must change the state of the rule.
To suppress a rule:
Click to open the Main Menu.
Click Threshold Crossing Rules under Notifications.
Locate the rule you want to suppress.
Click Disable.
Click in the Date/Time field to set when you want the rule to be automatically reenabled.
Click Disable.
Note the changes in the card:
The state is now marked as Inactive, but remains green
The date and time that the rule will be enabled is noted in the Suppressed field
The Disable option has changed to Disable Forever. Refer to Disable a Rule for information about this change.
Disable a Rule
To disable a rule until you want to manually reenable it, you must change the state of the rule.
To disable a rule that is currently active:
Click to open the Main Menu.
Click Threshold Crossing Rules under Notifications.
Locate the rule you want to disable.
Click Disable.
Leave the Date/Time field blank.
Click Disable.
Note the changes in the card:
The state is now marked as Inactive and is red
The rule definition is grayed out
The Disable option has changed to Enable to reactivate the rule when you are ready
To disable a rule that is currently suppressed:
Click to open the Main Menu.
Click Threshold Crossing Rules under Notifications.
Locate the rule you want to disable.
Click Disable Forever.
Note the changes in the card:
The state is now marked as Inactive and is red
The rule definition is grayed out
The Disable option has changed to Enable to reactivate the rule when you are ready
Delete a Rule
You might find that you no longer want to received event notifications for a particular TCA event. In that case, you can either disable the event if you think you may want to receive them again or delete the rule altogether. Refer to Disable a Rule in the first case. Follow the instructions here to remove the rule. The rule can be in any of the three states.
To delete a rule:
Click to open the Main Menu.
Click Threshold Crossing Rules under Notifications.
Locate the rule you want to remove and hover over the card.
Click .
Resolve Scope Conflicts
There may be occasions where the scope defined by multiple rules for a given TCA event may overlap each other. In such cases, the TCA rule with the most specific scope that is still true is used to generate the event.
To clarify this, consider this example. Three events have occurred:
First event on switch leaf01, interface swp1
Second event on switch leaf01, interface swp3
Third event on switch spine01, interface swp1
NetQ attempts to match the TCA event against hostname and interface name with three TCA rules with different scopes:
Scope 1 send events for the swp1 interface on switch leaf01 (very specific)
Scope 2 send events for all interfaces on switches that start with leaf (moderately specific)
Scope 3 send events for all switches and interfaces (very broad)
The result is:
For the first event, NetQ applies the scope from rule 1 because it matches scope 1 exactly
For the second event, NetQ applies the scope from rule 2 because it does not match scope 1, but does match scope 2
For the third event, NetQ applies the scope from rule 3 because it does not match either scope 1 or scope 2
In summary:

Configure Multiple Premises
The NetQ Management dashboard provides the ability to configure a single NetQ UI and CLI for monitoring data from multiple external premises in addition to your local premises.
A complete NetQ deployment is required at each premises. The NetQ appliance or VM of one of the deployments acts as the primary (similar to a proxy) for the premises in the other deployments. A list of these external premises is stored with the primary deployment. After the multiple premises are configured, you can view this list of external premises, change the name of premises on the list, and delete premises from the list.
To configure monitoring of external premises:
Sign in to primary NetQ Appliance or VM.
In the NetQ UI, click .
Select Management from the Admin column.
Locate the External Premises card.
Click Manage.
Click to open the Add Premises dialog.
Specify an external premises.
Enter an IP address for the API gateway on the external NetQ Appliance or VM in the Hostname field (required)
Enter the access credentials
Click Next.
Select from the available premises associated with this deployment by clicking on their names.
Click Finish.
Add more external premises by repeating Steps 6-10.
System Server Information
You can easily view the configuration of the physical server or VM from the NetQ Management dashboard.
To view the server information:
Click .
Select Management from the Admin column.
Locate the System Server Info card.
If no data is present on this card, it is likely that the NetQ Agent on your server or VM is not running properly or the underlying streaming services are impaired.
Integrate with Your LDAP Server
For on-premises deployments you can integrate your LDAP server with NetQ to provide access to NetQ using LDAP user accounts instead of ,or in addition to, the NetQ user accounts. Refer to Integrate NetQ with Your LDAP Server for more detail.
Provision Your Devices and Network
NetQ enables you to provision your switches using the lifecycle management feature in the NetQ UI or the NetQ CLI. Also included here are management procedures for NetQ Agents and optional post-installation configurations.
Manage Switches through Their Lifecycle
Only administrative users can perform the tasks described in this topic.
As an administrator, you want to manage the deployment of Cumulus Networks product software onto your network devices (servers, appliances, and switches) in the most efficient way and with the most information about the process as possible. With this release, NetQ expands its lifecycle management (LCM) capabilities to support configuration management for Cumulus Linux switches.
Using the NetQ UI or CLI, lifecycle management enables you to:
Manage Cumulus Linux and Cumulus NetQ images in a local repository
Configure switch access credentials (required for installations and upgrades)
Manage Cumulus Linux switches
Create snapshots of the network state at various times
Create Cumulus Linux switch configurations, with or without network templates
Create Cumulus NetQ configuration profiles
Upgrade Cumulus NetQ (Agents and CLI) on Cumulus Linux switches with Cumulus NetQ Agents version 2.4.x or later
Install or upgrade Cumulus NetQ (Agents and CLI) on Cumulus Linux switches with or without Cumulus NetQ Agents; all in a single job
Upgrade Cumulus Linux on switches with Cumulus NetQ Agents version 2.4.x or later (includes upgrade of NetQ to 3.x)
View a result history of upgrade attempts
This feature is fully enabled for on-premises deployments and fully disabled for cloud deployments. Contact your local Cumulus Networks sales representative or submit a support ticket to activate LCM on cloud deployments.
Access Lifecycle Management Features in the NetQ UI
To manage the various lifecycle management features from any workbench, click (Switches) in the workbench header, then select Manage switches.
The first time you open the Manage Switch Assets view, it provides a summary card for switch inventory, uploaded Cumulus Linux images, uploaded NetQ images, NetQ configuration profiles, and switch access settings. Additional cards appear after that based on your activity.
You can also access this view by clicking (Main Menu) and selecting Manage Switches from the Admin section.
NetQ CLI Lifecycle Management Commands Summary
The NetQ CLI provides a number of netq lcm commands to perform the various LCM capabilities. The syntax of these commands is:
netq lcm upgrade name <text-job-name> cl-version <text-cumulus-linux-version> netq-version <text-netq-version> hostnames <text-switch-hostnames> [run-restore-on-failure] [run-before-after]
netq lcm add credentials username <text-switch-username> (password <text-switch-password> | ssh-key <text-ssh-key>)
netq lcm add role (superspine | spine | leaf | exit) switches <text-switch-hostnames>
netq lcm del credentials
netq lcm show credentials [json]
netq lcm show switches [version <text-cumulus-linux-version>] [json]
netq lcm show status <text-lcm-job-id> [json]
netq lcm add cl-image <text-image-path>
netq lcm add netq-image <text-image-path>
netq lcm del image <text-image-id>
netq lcm show images [<text-image-id>] [json]
netq lcm show upgrade-jobs [json]
netq [<hostname>] show events [level info | level error | level warning | level critical | level debug] type lcm [between <text-time> and <text-endtime>] [json]
Manage Cumulus Linux and NetQ Images
You can manage both Cumulus Linux and Cumulus NetQ images with LCM. They are managed in a similar manner.
Cumulus Linux binary images can be uploaded to a local LCM repository for upgrade of your switches. Cumulus NetQ debian packages can be uploaded to the local LCM repository for installation or upgrade. You can upload images from an external drive.
The Linux and NetQ images are available in several variants based on the software version (x.y.z), the CPU architecture (ARM, x86), platform (based on ASIC vendor, Broadcom or Mellanox), SHA Checksum, and so forth. When LCM discovers Cumulus Linux switches running NetQ 2.x or later in your network, it extracts the meta data needed to select the appropriate image for a given switch. Similarly, LCM discovers and extracts the meta data from NetQ images.
The Cumulus Linux Images and NetQ Images cards in the NetQ UI provide a summary of image status in LCM. They show the total number of images in the repository, a count of missing images, and the starting points for adding and managing your images.
The netq lcm show images command also displays a summary of the images uploaded to the LCM repo on the NetQ appliance or VM.
Default Cumulus Linux or Cumulus NetQ Version Assignment
In the NetQ UI, you can assign a specific Cumulus Linux or Cumulus NetQ version as the default version to use during installation or upgrade of switches. It is recommended that you choose the newest version that you intend to install or upgrade on all, or the majority, of your switches. The default selection can be overridden during individual installation and upgrade job creation if an alternate version is needed for a given set of switches.
Missing Images
You should upload images for each variant of Cumulus Linux and Cumulus NetQ currently installed on the switches in your inventory if you want to support rolling back to a known good version should an installation or upgrade fail. The NetQ UI prompts you to upload any missing images to the repository.
For example, if you have both Cumulus Linux 3.7.3 and 3.7.11 versions, some running on ARM and some on x86 architectures, then LCM verifies the presence of each of these images. If only the 3.7.3 x86, 3.7.3 ARM, and 3.7.11 x86 images are in the repository, the NetQ UI would list the 3.7.11 ARM image as missing. For Cumulus NetQ, you need both the netq-apps and netq-agent packages for each release variant.
If you have specified a default Cumulus Linux and/or Cumulus NetQ version, the NetQ UI also verifies that the necessary versions of the default image are available based on the known switch inventory, and if not, lists those that are missing.
While it is not required that you upload images that NetQ determines to be missing, not doing so may cause failures when you attempt to upgrade your switches.
Upload Images
For fresh installations of NetQ 3.2, no images have yet been uploaded to the LCM repository. If you are upgrading from NetQ 3.0.0 or 3.1.0, the Cumulus Linux images you have previously added are still present.
In preparation for Cumulus Linux upgrades, the recommended image upload flow is:
In a fresh NetQ install, add images that match your current inventory: Upload Missing Images
Use the following instructions to upload missing Cumulus Linux and NetQ images:
For Cumulus Linux images:
On the Cumulus Linux Images card, click the View # missing CL images link to see what images you need. This opens the list of missing images.
If you have already specified a default image, you must click Manage and then Missing to see the missing images.
Select one or more of the missing images and make note of the version, ASIC Vendor, and CPU architecture for each.
Note the Disk Space Utilized information in the header to verify that you have enough space to upload the Cumulus Linux images.
Download the Cumulus Linux disk images (.bin files) needed for upgrade from the MyMellanox downloads page, selecting the appropriate version, CPU, and ASIC. Place them in an accessible part of your local network.
Back in the UI, click (Add Image) above the table.
Provide the .bin file from an external drive that matches the criteria for the selected image(s), either by dragging and dropping onto the dialog or by selecting from a directory.
Click Import.
On successful completion, you receive confirmation of the upload and the Disk Space Utilization is updated.
If the upload was not successful, an Image Import Failed message is shown. Close the Import Image dialog and try uploading the file again.
Click Done.
Click Uploaded to verify the image is in the repository.
Click to return to the LCM dashboard.
The Cumulus Linux Images card now shows the number of images you uploaded.
Download the Cumulus Linux disk images (.bin files) needed for upgrade from the MyMellanox downloads page, selecting the appropriate version, CPU, and ASIC. Place them in an accessible part of your local network.
Upload the images to the LCM repository. This example uses a Cumulus Linux 4.1.0 disk image.
Repeat Step 2 for each image you need to upload to the LCM repository.
For Cumulus NetQ images:
On the NetQ Images card, click the View # missing NetQ images link to see what images you need. This opens the list of missing images.
If you have already specified a default image, you must click Manage and then Missing to see the missing images.
Select one or all of the missing images and make note of the OS version, CPU architecture, and image type. Remember that you need both image types for NetQ to perform the installation or upgrade.
Download the Cumulus NetQ debian packages needed for upgrade from the MyMellanox downloads page, selecting the appropriate version and hypervisor/platform. Place them in an accessible part of your local network.
Back in the UI, click (Add Image) above the table.
Provide the .deb file(s) from an external drive that matches the criteria for the selected image, either by dragging and dropping it onto the dialog or by selecting it from a directory.
Click Import.
On successful completion, you receive confirmation of the upload.
If the upload was not successful, an Image Import Failed message is shown. Close the Import Image dialog and try uploading the file again.
Click Done.
Click Uploaded to verify the images are in the repository.
When all of the missing images have been uploaded, the Missing list will be empty.
Click to return to the LCM dashboard.
The NetQ Images card now shows the number of images you uploaded.
Download the Cumulus NetQ debian packages needed for upgrade from the MyMellanox downloads page, selecting the appropriate version and hypervisor/platform. Place them in an accessible part of your local network.
Upload the images to the LCM repository. This example uploads the two packages (netq-agent and netq-apps) needed for NetQ version 3.2.0 for a NetQ appliance or VM running Ubuntu 18.04 with an x86 architecture.
To upload the Cumulus Linux or Cumulus NetQ images that you want to use for upgrade:
First download the Cumulus Linux disk images (.bin files) and Cumulus NetQ debian packages needed for upgrade from the MyMellanox downloads. Place them in an accessible part of your local network.
If you are upgrading Cumulus Linux on switches with different ASIC vendors or CPU architectures, you will need more than one image. For NetQ, you need both the netq-apps and netq-agent packages for each variant.
Then continue with the instructions here based on whether you want to use the NetQ UI or CLI.
Click Add Image on the Cumulus Linux Images or NetQ Images card.
Provide one or more images from an external drive, either by dragging and dropping onto the dialog or by selecting from a directory.
Click Import.
Monitor the progress until it completes. Click Done.
Click to return to the LCM dashboard.
The NetQ Images card is updated to show the number of additional images you uploaded.
Use the netq lcm add cl-image <text-image-path> and netq lcm add netq-image <text-image-path> commands to upload the images. Run the relevant command for each image that needs to be uploaded.
Lifecycle management does not have a default Cumulus Linux or Cumulus NetQ upgrade version specified automatically. With the NetQ UI, you can specify the version that is appropriate for your network to ease the upgrade process.
To specify a default Cumulus Linux or Cumulus NetQ version in the NetQ UI:
Click the Click here to set the default CL version link in the middle of the Cumulus Linux Images card, or click the Click here to set the default NetQ version link in the middle of the NetQ Images card.

You can remove the access credentials for switches using the NetQ CLI. Note that without valid credentials, you will not be able to upgrade your switches.
To remove the credentials, run netq lcm del credentials. Verify they are removed by running netq lcm show credentials.
Manage Switch Inventory and Roles
On initial installation, the lifecycle management feature provides an inventory of switches that have been automatically discovered by NetQ 3.x and are available for software installation or upgrade through NetQ. This includes all switches running Cumulus Linux 3.6 or later and Cumulus NetQ Agent 2.4 or later in your network. You assign network roles to switches and select switches for software installation and upgrade from this inventory listing.
View the LCM Switch Inventory
The switch inventory can be viewed from the NetQ UI and the NetQ CLI.
A count of the switches NetQ was able to discover and the Cumulus Linux versions that are running on those switches is available from the LCM dashboard.
To view a list of all switches known to lifecycle management, click Manage on the Switches card.
Review the list:
Sort the list by any column; hover over column title and click to toggle between ascending and descending order
Filter the list: click and enter parameter value of interest
If you have more than one Cumulus Linux version running on your switches, you can click a version segment on the Switches card graph to open a list of switches pre-filtered by that version.
To view a list of all switches known to lifecycle management, run:
netq lcm show switches [version <text-cumulus-linux-version>] [json]
Use the version option to only show switches with a given Cumulus Linux version, X.Y.Z.
This example shows all switches known by lifecycle management.
This listing is the starting point for Cumulus Linux upgrades or Cumulus NetQ installations and upgrades. If the switches you want to upgrade are not present in the list, you can:
Work with the list you have and add them later
Verify the missing switches are reachable using ping
Verify the NetQ Agent is fresh and version 2.4.0 or later for switches that already have the agent installed (click , then click Agents or run netq show agents)
Install NetQ on the switch (refer to Install NetQ)
Upgrade any NetQ Agents if needed. Refer to Upgrade NetQ Agents for instructions.
Role Management
Four pre-defined switch roles are available based on the Clos architecture: Superspine, Spine, Leaf, and Exit. With this release, you cannot create your own roles.
Switch roles are used to:
Identify switch dependencies and determine the order in which switches are upgraded
Determine when to stop the process if a failure is encountered
When roles are assigned, the upgrade process begins with switches having the superspine role, then continues with the spine switches, leaf switches, exit switches, and finally switches with no role assigned. All switches with a given role must be successfully upgraded before the switches with the closest dependent role can be upgraded.
For example, a group of seven switches are selected for upgrade. Three are spine switches and four are leaf switches. After all of the spine switches are successfully upgraded, then the leaf switches are upgraded. If one of the spine switches were to fail the upgrade, the other two spine switches are upgraded, but the upgrade process stops after that, leaving the leaf switches untouched, and the upgrade job fails.
When only some of the selected switches have roles assigned in an upgrade job, the switches with roles are upgraded first and then all the switches with no roles assigned are upgraded.
While role assignment is optional, using roles can prevent switches from becoming unreachable due to dependencies between switches or single attachments. And when MLAG pairs are deployed, switch roles avoid upgrade conflicts. For these reasons, Cumulus Networks highly recommends assigning roles to all of your switches.
Assign Switch Roles
Roles can be assigned to one or more switches using the NetQ UI or the NetQ CLI.
Open the LCM dashboard.
On the Switches card, click Manage.
Select one switch or multiple switches that should be assigned to the same role.
Click .
Select the role that applies to the selected switch(es).
Click Assign.
Note that the Role column is updated with the role assigned to the selected switch(es).
Continue selecting switches and assigning roles until most or all switches have roles assigned.
A bonus of assigning roles to switches is that you can then filter the list of switches by their roles by clicking the appropriate tab.
For multiple switches to be assigned the same role, separate the hostnames with commas (no spaces). This example configures leaf01 through leaf04 switches with the leaf role:
netq lcm add role leaf switches leaf01,leaf02,leaf03,leaf04
View Switch Roles
You can view the roles assigned to the switches in the LCM inventory at any time.
Open the LCM dashboard.
On the Switches card, click Manage.
The assigned role is displayed in the Role column of the listing.
To view all switch roles, run:
netq lcm show switches [version <text-cumulus-linux-version>] [json]
Use the version option to only show switches with a given Cumulus Linux version, X.Y.Z.
This example shows the role of all switches in the Role column of the listing.
If you accidentally assign an incorrect role to a switch, it can easily be changed to the correct role.
To change a switch role:
Open the LCM dashboard.
On the Switches card, click Manage.
Select the switches with the incorrect role from the list.
Click .

Manage Switch Configurations
You can use the NetQ UI to configure switches using one or more switch configurations. To enable consistent application of configurations, switch configurations can contain network templates for SNMP, NTP, and user accounts, and configuration profiles for Cumulus NetQ Agents.
If you intend to use network templates or configuration profiles, the recommended workflow is as follows:
Manage Network Templates
Network templates provide administrators the option to create switch configuration profiles that can be applied to multiple switches. They can help reduce inconsistencies with switch configuration and speed the process of initial configuration and upgrades. No default templates are provided.
View Network Templates
You can view existing templates using the Network Templates card.
Open the lifecycle management (Manage Switch Assets) dashboard.
Locate the Network Templates card.
Click Manage to view the list of existing switch templates.
Create Network Templates
No default templates are provided on installation of NetQ. This enables you to create configurations that match your specifications.
To create a network template:
Open the lifecycle management (Manage Switch Assets) dashboard.
Click Add on the Network Templates card.
Click Create New.
Decide which aspects of configuration you want included in this template: SNMP, NTP, and/or User accounts.
You can specify your template in any order, but to complete the configuration, you must open the User form to click Save and Finish.
Configure the template using the following instructions.
SNMP provides a way to query, monitor, and manage your devices in addition to NetQ.
To create a network template with SNMP parameters included:
Provide a name for the template. This field is required and can be a maximum of 22 characters, including spaces.
All other parameters are optional. Configure those as desired, and described here.
Enter a comma-separated list of IP addresses of the SNMP Agents on the switches and hosts in your network.

Above the switches (right), management tools to help find the switches you want to assign with this configuration, including select all, clear, filter, and search.
Select the switches to be assigned this configuration.
In this example, we searched for all leaf switches, then clicked select all.
Click Save and Finish.
To run the job to apply the configuration, you first have the option to change the hostnames of the selected switches.
Either change the hostnames and then click Continue or just click Continue without changing the hostnames.
Enter a name for the job (maximum of 22 characters including spaces), then click Continue.
This opens the monitoring page for the assignment jobs, similar to the upgrade jobs. The job title bar indicates the name of the switch configuration being applied and the number of switches that to be assigned with the configuration. (After you have mulitple switch configurations created, you might have more than one configuration being applied in a single job.) Each switch element indicates its hostname, IP address, installed Cumulus Linux and NetQ versions, a note indicating this is a new assignment, the switch configuration being applied, and a menu that provides the detailed steps being executed. The last is useful when the assignment fails as any errors are included in this popup.
Click to return to the switch configuration page where you can either create another configuration and apply it. If you are finished assigning switch configurations to switches, click to return to the lifecycle management dashboard.
When you return the dashboard, your Switch Configurations card shows the new configurations and the Config Assignment History card appears that shows a summary status of all configuration assignment jobs attempted.
Click View on the Config Assignment History card to open the details of all assignment jobs. Refer to Manage Switch Configurations for more detail about this card.
Edit a Switch Configuration
You can edit a switch configuration at any time. After you have made changes to the configuration, you can apply it to the same set of switches or modify the switches using the configuration as part of the editing process.
To edit a switch configuration:
Locate the Switch Configurations card on the lifecycle management dashboard.
Click Manage.
Locate the configuration you want to edit. Scroll down or filter the listing to help find the configuration when there are multiple configurations.

Upgrade Cumulus NetQ Agent Using LCM
The lifecycle management (LCM) feature enables you to upgrade to Cumulus NetQ 3.2.0 on switches with an existing NetQ Agent 2.4.x, 3.0.0, or 3.1.0 release using the NetQ UI. You can upgrade only the NetQ Agent or upgrade both the NetQ Agent and the NetQ CLI at the same time. Up to five jobs can be run simultaneously; however, a given switch can only be contained in one running job at a time.
The upgrade workflow includes the following steps:
Upgrades can be performed from NetQ Agents of 2.4.x, 3.0.0, and 3.1.0 releases to the NetQ 3.2.0 release. Lifecycle management does not support upgrades from NetQ 2.3.1 or earlier releases; you must perform a new installation in these cases. Refer to Install NetQ Agents.
Prepare for a Cumulus NetQ Agent Upgrade

Upgrade Cumulus Linux Using LCM
LCM provides the ability to upgrade Cumulus Linux on one or more switches in your network through the NetQ UI or the NetQ CLI. Up to five upgrade jobs can be run simultaneously; however, a given switch can only be contained in one running job at a time.
Upgrades can be performed between Cumulus Linux 3.x releases, and between Cumulus Linux 4.x releases. Lifecycle management does not support upgrades from Cumulus Linux 3.x to 4.x releases.
Workflows for Cumulus Linux Upgrades Using LCM
There are three methods available through LCM for upgrading Cumulus Linux on your switches based on whether the NetQ Agent is already installed on the switch or not, and whether you want to use the NetQ UI or the NetQ CLI:
Use NetQ UI or NetQ CLI for switches with NetQ 2.4.x or later Agent already installed
Use NetQ UI for switches without NetQ Agent installed
The workflows vary slightly with each approach:
Using the NetQ UI for switches with NetQ Agent installed, the workflow is:
Using the NetQ CLI for switches with NetQ Agent installed, the workflow is:
Using the NetQ UI for switches without NetQ Agent installed, the workflow is:
Upgrade Cumulus Linux on Switches with NetQ Agent Installed
You can upgrade Cumulus Linux on switches that already have a NetQ Agent (version 2.4.x or later) installed using either the NetQ UI or NetQ CLI.
Prepare for Upgrade
Click (Switches) in any workbench header, then click Manage switches.
Assign a role to each switch (optional, but recommended).
Perform a Cumulus Linux Upgrade
Upgrade Cumulus Linux on switches through either the NetQ UI or NetQ CLI:
Click (Switches) in any workbench header, then select Manage switches.
Click Manage on the Switches card.
Select the individual switches (or click to select all switches) that you want to upgrade. If needed, use the filter to the narrow the listing and find the relevant switches.
Click (Upgrade CL) above the table.
From this point forward, the software walks you through the upgrade process, beginning with a review of the switches that you selected for upgrade.
Give the upgrade job a name. This is required, but can be no more than 22 characters, including spaces and special characters.
Verify that the switches you selected are included, and that they have the correct IP address and roles assigned.
If you accidentally included a switch that you do NOT want to upgrade, hover over the switch information card and click to remove it from the upgrade job.
If the role is incorrect or missing, click , then select a role for that switch from the dropdown. Click to discard a role change.
When you are satisfied that the list of switches is accurate for the job, click Next.
Verify that you want to use the default Cumulus Linux or NetQ version for this upgrade job. If not, click Custom and select an alternate image from the list.
Default CL Version Selected
Custom CL Version Selected
Note that the switch access authentication method, Using global access credentials, indicates you have chosen either basic authentication with a username and password or SSH key-based authentication for all of your switches. Authentication on a per switch basis is not currently available.
Click Next.
Verify the upgrade job options.
By default, NetQ takes a network snapshot before the upgrade and then one after the upgrade is complete. It also performs a roll back to the original Cumulus Linux version on any server which fails to upgrade.
You can exclude selected services and protocols from the snapshots. By default, node and services are included, but you can deselect any of the other items. Click on one to remove it; click again to include it. This is helpful when you are not running a particular protocol or you have concerns about the amount of time it will take to run the snapshot. Note that removing services or protocols from the job may produce non-equivalent results compared with prior snapshots.
While these options provide a smoother upgrade process and are highly recommended, you have the option to disable these options by clicking No next to one or both options.
Click Next.
After the pre-checks have completed successfully, click Preview. If there are failures, refer to Precheck Failures.
These checks verify the following:
Selected switches are not currently scheduled for, or in the middle of, a Cumulus Linux or NetQ Agent upgrade
Selected versions of Cumulus Linux and NetQ Agent are valid upgrade paths
All mandatory parameters have valid values, including MLAG configurations
All switches are reachable
The order to upgrade the switches, based on roles and configurations
Review the job preview.
When all of your switches have roles assigned, this view displays the chosen job options (top center), the pre-checks status (top right and left in Pre-Upgrade Tasks), the order in which the switches are planned for upgrade (center; upgrade starts from the left), and the post-upgrade tasks status (right).
Roles assigned
When none of your switches have roles assigned or they are all of the same role, this view displays the chosen job options (top center), the pre-checks status (top right and left in Pre-Upgrade Tasks), a list of switches planned for upgrade (center), and the post-upgrade tasks status (right).
All roles the same
When some of your switches have roles assigned, any switches without roles are upgraded last and are grouped under the label *Stage1*.
Some roles assigned
When you are happy with the job specifications, click Start Upgrade.
Click Yes to confirm that you want to continue with the upgrade, or click Cancel to discard the upgrade job.
Perform the upgrade using the netq lcm upgrade command, providing a name for the upgrade job, the Cumulus Linux and NetQ version, and the hostname(s) to be upgraded:
Optionally, you can apply some job options, including creation of network snapshots and previous version restoration if a failure occurs.
Network Snapshot Creation
You can also generate a Network Snapshot before and after the upgrade by adding the run-before-after option to the command:
cumulus@switch:~$ netq lcm upgrade name upgrade-3712 cl-version 3.7.12 netq-version 3.1.0 hostnames spine01,spine02,leaf01,leaf02 order spine,leaf run-before-after
Restore on an Upgrade Failure
You can have LCM restore the previous version of Cumulus Linux if the upgrade job fails by adding the run-restore-on-failure option to the command. This is highly recommended.
cumulus@switch:~$ netq lcm upgrade name upgrade-3712 cl-version 3.7.12 netq-version 3.1.0 hostnames spine01,spine02,leaf01,leaf02 order spine,leaf run-restore-on-failure
Precheck Failures
If one or more of the pre-checks fail, resolve the related issue and start the upgrade again. In the NetQ UI these failures appear on the Upgrade Preview page. In the NetQ CLI, it appears in the form of error messages in the netq lcm show upgrade-jobs command output.
Expand the following dropdown to view common failures, their causes and corrective actions.

Reasons for Upgrade Job Failure
Upgrades can fail at any of the stages of the process, including when backing up data, upgrading the Cumulus Linux software, and restoring the data. Failures can occur when attempting to connect to a switch or perform a particular task on the switch.
Some of the common reasons for upgrade failures and the errors they present:

Upgrade Cumulus Linux on Switches Without NetQ Agent Installed
When you want to update Cumulus Linux on switches without NetQ installed, NetQ provides the LCM switch discovery feature. The feature browses your network to find all Cumulus Linux Switches, with and without NetQ currently installed and determines the versions of Cumulus Linux and NetQ installed. The results of switch discovery are then used to install or upgrade Cumulus Linux and Cumulus NetQ on all discovered switches in a single procedure rather than in two steps. Up to five jobs can be run simultaneously; however, a given switch can only be contained in one running job at a time.
If all of your Cumulus Linux switches already have NetQ 2.4.x or later installed, you can upgrade them directly. Refer to Upgrade Cumulus Linux.
To discover switches running Cumulus Linux and upgrade Cumulus Linux and NetQ on them:
Click (Main Menu) and select Upgrade Switches, or click (Switches) in the workbench header, then click Manage switches.
On the Switches card, click Discover.
Enter a name for the scan.
Choose whether you want to look for switches by entering IP address ranges OR import switches using a comma-separated values (CSV) file.
If you do not have a switch listing, then you can manually add the address ranges where your switches are located in the network. This has the advantage of catching switches that may have been missed in a file.
A maximum of 50 addresses can be included in an address range. If necessary, break the range into smaller ranges.
To discover switches using address ranges:
Enter an IP address range in the IP Range field.
Ranges can be contiguous, for example 192.168.0.24-64, or non-contiguous, for example 192.168.0.24-64,128-190,235, but they must be contained within a single subnet.
Optionally, enter another IP address range (in a different subnet) by clicking .
For example, 198.51.100.0-128 or 198.51.100.0-128,190,200-253.
Add additional ranges as needed. Click to remove a range if needed.
If you decide to use a CSV file instead, the ranges you entered will remain if you return to using IP ranges again.
If you have a file of switches that you want to import, then it can be easier to use that, than to enter the IP address ranges manually.
To import switches through a CSV file:
Click Browse.
Select the CSV file containing the list of switches.
The CSV file must include a header containing hostname, ip, and port. They can be in any order you like, but the data must match that order. For example, a CSV file that represents the Cumulus reference topology could look like this:
or this:
You must have an IP address in your file, but the hostname is optional and if the port is blank, NetQ uses switch port 22 by default.
Click Remove if you decide to use a different file or want to use IP address ranges instead. If you had entered ranges prior to selecting the CSV file option, they will have remained.
Note that the switch access credentials defined in Manage Switch Credentials are used to access these switches. If you have issues accessing the switches, you may need to update your credentials.
Click Next.
When the network discovery is complete, NetQ presents the number of Cumulus Linux switches it has found. They are displayed in categories:
Discovered without NetQ: Switches found without NetQ installed
Discovered with NetQ: Switches found with some version of NetQ installed
Discovered but Rotten: Switches found that are unreachable
Incorrect Credentials: Switches found that cannot be reached because the provided access credentials do not match those for the switches
OS not Supported: Switches found that are running Cumulus Linux version not supported by the LCM upgrade feature
Not Discovered: IP addresses which did not have an associated Cumulus Linux switch
If no switches are found for a particular category, that category is not displayed.
Select which switches you want to upgrade from each category by clicking the checkbox on each switch card.
Click Next.
Verify the number of switches identified for upgrade and the configuration profile to be applied is correct.
Accept the default NetQ version or click Custom and select an alternate version.
By default, the NetQ Agent and CLI are upgraded on the selected switches. If you do not want to upgrade the NetQ CLI, click Advanced and change the selection to No.
Click Next.
Several checks are performed to eliminate preventable problems during the install process.
These checks verify the following:
Selected switches are not currently scheduled for, or in the middle of, a Cumulus Linux or NetQ Agent upgrade
Selected versions of Cumulus Linux and NetQ Agent are valid upgrade paths
All mandatory parameters have valid values, including MLAG configurations
All switches are reachable
The order to upgrade the switches, based on roles and configurations
If any of the pre-checks fail, review the error messages and take appropriate action.
If all of the pre-checks pass, click Install to initiate the job.
Monitor the job progress.
After starting the upgrade you can monitor the progress from the preview page or the Upgrade History page.
From the preview page, a green circle with rotating arrows is shown on each switch as it is working. Alternately, you can close the detail of the job and see a summary of all current and past upgrade jobs on the NetQ Install and Upgrade History page. The job started most recently is shown at the top, and the data is refreshed periodically.
If you are disconnected while the job is in progress, it may appear as if nothing is happening. Try closing (click ) and reopening your view (click ), or refreshing the page.
Several viewing options are available for monitoring the upgrade job.
Monitor the job with full details open:
Monitor the job with only summary information in the NetQ Install and Upgrade History page. Open this view by clicking in the full details view; useful when you have multiple jobs running simultaneously
Monitor the job through the NetQ Install and Upgrade History card on the LCM dashboard. Click twice to return to the LCM dashboard.
Investigate any failures and create new jobs to reattempt the upgrade.
Manage Network Snapshots
Creating and comparing network snapshots can be useful to validate that the network state has not changed. Snapshots are typically created when you upgrade or change the configuration of your switches in some way. This section describes the Snapshot card and content, as well as how to create and compare network snapshots at any time. Snapshots can be automatically created during the upgrade process for Cumulus Linux. Refer to Perform a Cumulus Linux Upgrade.
Create a Network Snapshot
It is simple to capture the state of your network currently or for a time in the past using the snapshot feature.
To create a snapshot:
From any workbench in the NetQ UI, click in the workbench header.
Click Create Snapshot.
Enter a name for the snapshot.
Choose the time for the snapshot:
For the current network state, click Now.
For the network state at a previous date and time, click Past, then click in Start Time field to use the calendar to step through selection of the date and time. You may need to scroll down to see the entire calendar.
Choose the services to include in the snapshot.
In the Choose options field, click any service name to remove that service from the snapshot. This would be appropriate if you do not support a particular service, or you are concerned that including that service might cause the snapshot to take an excessive amount of time to complete if included. The checkmark next to the service and the service itself is grayed out when the service is removed. Click any service again to re-include the service in the snapshot. The checkmark is highlighted in green next to the service name and is no longer grayed out.
The Node and Services options are mandatory, and cannot be selected or unselected.
If you remove services, be aware that snapshots taken in the past or future may not be equivalent when performing a network state comparison.
This example removes the OSPF and Route services from the snapshot being created.
Optionally, scroll down and click in the Notes field to add descriptive text for the snapshot to remind you of its purpose. For example: “This was taken before adding MLAG pairs,” or “Taken after removing the leaf36 switch.”
Click Finish.
A medium Snapshot card appears on your desktop. Spinning arrows are visible while it works. When it finishes you can see the number of items that have been captured, and if any failed. This example shows a successful result.
If you have already created other snapshots, Compare is active. Otherwise it is inactive (grayed-out).
When you are finished viewing the snapshot, click Dismiss to close the snapshot. The snapshot is not deleted, merely removed from the workbench.
Compare Network Snapshots
You can compare the state of your network before and after an upgrade or other configuration change to validate that the changes have not created an unwanted change in your network state.
To compare network snapshots:
Create a snapshot (as described in previous section) before you make any changes.
Make your changes.
Create a second snapshot.
Compare the results of the two snapshots.
Depending on what, if any, cards are open on your workbench:
Put the cards next to each other to view a high-level comparison. Scroll down to see all of the items.
To view a more detailed comparison, click Compare on one of the cards. Select the other snapshot from the list.
Click Compare on the open card.
Select the other snapshot to compare.
Click .
Click Compare Snapshots.
Click on the two snapshots you want to compare.
Click Finish. Note that two snapshots must be selected before Finish is active.
In the latter two cases, the large Snapshot card opens. The only difference is in the card title. If you opened the comparison card from a snapshot on your workbench, the title includes the name of that card. If you open the comparison card through the Snapshot menu, the title is generic, indicating a comparison only. Functionally, you have reached the same point.
Scroll down to view all element comparisons.
Interpreting the Comparison Data
For each network element that is compared, count values and changes are shown:
In this example, a change was made to the VLAN. The snapshot taken before the change (17Apr2020) had a total count of 765 neighbors. The snapshot taken after the change (20Apr2020) had a total count of 771 neighbors. Between the two totals you can see the number of neighbors added and removed from one time to the next, resulting in six new neighbors after the change.
The red and green coloring indicates only that items were removed (red) or added (green). The coloring does not indicate whether the removal or addition of these items is bad or good.
From this card, you can also change which snapshots to compare. Select an alternate snapshot from one of the two snapshot dropdowns and then click Compare.
View Change Details
You can view additional details about the changes that have occurred between the two snapshots by clicking View Details. This opens the full screen Detailed Snapshot Comparison card.
From this card you can:
View changes for each of the elements that had added and/or removed items, and various information about each; only elements with changes are presented
Filter the added and removed items by clicking
Export all differences in JSON file format by clicking
The following table describes the information provided for each element type when changes are present:

At various points in time, you might want to change which network nodes are being monitored by NetQ or look more closely at a network node for troubleshooting purposes. Adding the NetQ Agent to a switch or host is described in Install NetQ. Viewing the status of an Agent, disabling an Agent, managing NetQ Agent logging, and configuring the events the agent collects are presented here.
View NetQ Agent Status
To view the health of your NetQ Agents, run:

You can view the current configuration of a NetQ Agent to determine what data is being collected and where it is being sent. To view this configuration, run:
netq config show agent [kubernetes-monitor|loglevel|stats|sensors|frr-monitor|wjh|wjh-threshold|cpu-limit] [json]
This example shows a NetQ Agent in an on-premises deployment, talking to an appliance or VM at 127.0.0.1 using the default ports and VRF. No special configuration is included to monitor kubernetes, FRR, interface statistics, sensors, WJH. No limit has been set on the CPU usage or alter the default logging level.

Modify the Configuration of the NetQ Agent on a Node
The agent configuration commands enable you to do the following:
Add, Disable, and Remove a NetQ Agent
Start and Stop a NetQ Agent
Configure a NetQ Agent to Collect Selected Data (CPU usage limit, FRR, Kubernetes, sensors, WJH)
Configure a NetQ Agent to Send Data to a Server Cluster
Troubleshoot the NetQ Agent
Commands apply to one agent at a time, and are run from the switch or host where the NetQ Agent resides.
Add and Remove a NetQ Agent
Adding or removing a NetQ Agent is to add or remove the IP address (and port and VRF when specified) from NetQ configuration file (at /etc/netq/netq.yml). This adds or removes the information about the appliance or VM where the agent sends the data it collects.
To use the NetQ CLI to add or remove a NetQ Agent on a switch or host, run:
netq config add agent server <text-opta-ip> [port <text-opta-port>] [vrf <text-vrf-name>]
netq config del agent server
If you want to use a specific port on the appliance or VM, use the port option. If you want the data sent over a particular virtual route interface, use the vrf option.
This example shows how to add a NetQ Agent and tell it to send the data it collects to the NetQ Appliance or VM at the IPv4 address of 10.0.0.23 using the default port (on-premises = 31980; cloud = 443) and vrf (default).
You can temporarily disable NetQ Agent on a node. Disabling the NetQ Agent maintains the data already collected in the NetQ database, but stops the NetQ Agent from collecting new data until it is reenabled.
To disable a NetQ Agent, run:
cumulus@switch:~$ netq config stop agent
To reenable a NetQ Agent, run:
cumulus@switch:~$ netq config restart agent
Configure a NetQ Agent to Limit Switch CPU Usage
While not typically an issue, you can restrict the NetQ Agent from using more than a configurable amount of the CPU resources. This setting requires Cumulus Linux versions 3.6 or later or 4.1.0 or later to be running on the switch.
Configure a NetQ Agent to Send Data to a Server Cluster
If you have a server cluster arrangement for NetQ, you will want to configure the NetQ Agent to send the data it collects to all of the servers in the cluster.
To configure the agent to send data to the servers in your cluster, run:
The list of IP addresses must be separated by commas, but no spaces. You can optionally specify a port or VRF.
This example configures the NetQ Agent on a switch to send the data to three servers located at 10.0.0.21, 10.0.0.22, and 10.0.0.23 using the rocket VRF.
To stop a NetQ Agent from sending data to a server cluster, run:
cumulus@switch:~$ netq config del agent cluster-servers
Configure Logging to Troubleshoot a NetQ Agent
The logging level used for a NetQ Agent determines what types of events
are logged about the NetQ Agent on the switch or host.
First, you need to decide what level of logging you want to configure. You can configure the logging level to be the same for every NetQ Agent, or selectively increase or decrease the logging level for a NetQ Agent on a problematic node.
Logging Level
Description
debug
Sends notifications for all debugging-related, informational, warning, and error messages.
info
Sends notifications for informational, warning, and error messages (default).
warning
Sends notifications for warning and error messages.
error
Sends notifications for errors messages.
You can view the NetQ Agent log directly. Messages have the following structure:
If you have set the logging level to debug for troubleshooting, it is recommended that you either change the logging level to a less heavy mode or completely disable agent logging altogether when you are finished troubleshooting.
To change the logging level from debug to another level, run:
The NetQ Agent contains a pre-configured set of modular commands that run periodically and send event and resource data to the NetQ appliance or VM. You can fine tune which events the agent can poll and vary frequency of polling using the NetQ CLI.
For example, if your network is not running OSPF, you can disable the command that polls for OSPF events. Or you can decrease the polling interval for LLDP from the default of 60 seconds to 120 seconds. By not polling for selected data or polling less frequently, you can reduce switch CPU usage by the NetQ Agent.
Depending on the switch platform, some supported protocol commands may not be executed by the NetQ Agent. For example, if a switch has no VXLAN capability, then all VXLAN-related commands get skipped by agent.
You cannot create new commands in this release.
Supported Commands
To see the list of supported modular commands, run:
The NetQ predefined commands are described as follows:
agent_stats: Collects statistics about the NetQ Agent every five (5) minutes.
agent_util_stats: Collects switch CPU and memory utilization by the NetQ Agent every 30 seconds.
cl-support-json: Polls the switch every three (3) minutes to determine if a cl-support file was generated.
config-mon-json: Polls the /etc/network/interfaces, /etc/frr/frr.conf, /etc/lldpd.d/README.conf and /etc/ptm.d/topology.dot files every two (2) minutes to determine if the contents of any of these files has changed. If a change has occurred, the contents of the file and its modification time are transmitted to the NetQ appliance or VM.
ports: Polls for optics plugged into the switch every hour.
proc-net-dev: Polls for network statistics on the switch every 30 seconds.
running-config-mon-json: Polls the clagctl parameters every 30 seconds and sends a diff of any changes to the NetQ appliance or VM.
Modify the Polling Frequency
You can change the polling frequency of a modular command. The frequency is specified in seconds. For example, to change the polling frequency of the lldp-json command to 60 seconds from its default of 120 seconds, run:
You can disable any of these commands if they are not needed on your network. This can help reduce the compute resources the NetQ Agent consumes on the switch. For example, if your network does not run OSPF, you can disable the two OSPF commands:
This topic describes how to configure deployment options that can only be performed after installation or upgrade of NetQ is complete.
Install a Custom Signed Certificate
The NetQ UI version 3.0.x and later ships with a self-signed certificate which is sufficient for non-production environments or cloud deployments. For on-premises deployments, however, you receive a warning from your browser that this default certificate is not trusted when you first log in to the NetQ UI. You can avoid this by installing your own signed certificate.
The following items are needed to perform the certificate installation:
A valid X509 certificate
A private key file for the certificate
A DNS record name configured to access the NetQ UI
The FQDN should match the common name of the certificate. If you use a wild card in the common name — for example, if the common name of the certificate is *.example.com — then the NetQ telemetry server should reside on a subdomain of that domain, accessible via a URL like netq.example.com.
Cumulus NetQ must be installed and running
You can verify this by running the netq show opta-health command.
You can install a certificate using the Admin UI or the NetQ CLI.
Enter https://<hostname-or-ipaddr-of-netq-appliance-or-vm>:8443 in your broswer address bar to open the Admin UI.
From the Health page, click Settings.
Click Edit.
Enter the hostname, certificate and certificate key in the relevant fields.
Click Lock.
Log in to the NetQ On-premises Appliance or VM via SSH and copy your certificate and key file there.
Generate a Kubernetes secret called netq-gui-ingress-tls.
cumulus@netq-ts:~$ kubectl create secret tls netq-gui-ingress-tls \
--namespace default \
--key <name of your key file>.key \
--cert <name of your cert file>.crt
Verify that the secret is created.
cumulus@netq-ts:~$ kubectl get secret
NAME TYPE DATA AGE
netq-gui-ingress-tls kubernetes.io/tls 2 5s
Update the ingress rule file to install self-signed certificates.
A message like the one here is shown if your ingress rule is successfully configured.
Your custom certificate should now be working. Verify this by opening the NetQ UI at https://<your-hostname-or-ipaddr> in your browser.
Update Your Cloud Activation Key
The cloud activation key is the one used to access the Cloud services, not the authorization keys used for configuring the CLI. It is provided by Cumulus Networks when your premises is set up. It is called the config-key.
There are occasions where you might want to update your cloud service activation key. For example, if you mistyped the key during installation and now your existing key does not work, or you received a new key for your premises from Cumulus Networks.
Update the activation key using the Admin UI or NetQ CLI:
Open the Admin UI by entering https://<master-hostname-or-ipaddress>:8443 in your browser address field.
Click Settings.
Click Activation.
Click Edit.
Enter your new configuration key in the designated text box.
Click Apply.
Run the following command on your standalone or master NetQ Cloud Appliance or VM replacing text-opta-key with your new key.
Installation of NetQ with a server cluster sets up the master and two worker nodes. To expand your cluster to include up to a total of nine worker nodes, use the Admin UI.
Adding additional worker nodes increases availability, but does not increase scalability at this time. A maximum of 1000 nodes is supported regardless of the number of worker nodes in your cluster.
To add more worker nodes:
Prepare the nodes. Refer to the relevant server cluster instructions in Install the NetQ System.
Open the Admin UI by entering https://<master-hostname-or-ipaddress>:8443 in your browser address field.
This opens the Health dashboard for NetQ.
Click Cluster to view your current configuration.
On-premises deployment
This opens the Cluster dashboard, with the details about each node in the cluster.
Click Add Worker Node.
Enter the private IP address of the node you want to add.
Click Add.
Monitor the progress of the three jobs by clicking next to the jobs.
On completion, a card for the new node is added to the Cluster dashboard.
If the addition fails for any reason, download the log file by clicking , run netq bootstrap reset on this new worker node, and then try again.
Repeat this process to add more worker nodes as needed.
Manage Inventory
This topic describes how to use the Cumulus NetQ UI and CLI to monitor your inventory from networkwide and device-specific perspectives.
You can monitor all of the hardware and software components installed and running on the switches and hosts across the entire network. This is extremely useful for understanding the dependence on various vendors and versions, when planning upgrades or the scope of any other required changes.
From a networkwide view, you can monitor all of the switches and hosts at once, or you can monitor all of the switches at once. You cannot currently monitor all hosts at once separate from switches.
Monitor Networkwide Inventory
With the NetQ UI and CLI, a user can monitor the inventory on a networkwide basis for all switches and hosts, or all switches. Inventory includes such items as the number of each device and what operating systems are installed. Additional details are available about the hardware and software components on individual switches, such as the motherboard, ASIC, microprocessor, disk, memory, fan and power supply information. This is extremely useful for understanding the dependence on various vendors and versions when planning upgrades or evaluating the scope of any other required changes.
The commands and cards available to obtain this type of information help you to answer questions such as:
What switches are being monitored in the network?
What is the distribution of ASICs, CPUs, Agents, and so forth across my network?
The Cumulus NetQ UI provides the Inventory|Devices card for monitoring networkwide inventory information for all switches and hosts. The Inventory|Switches card provides a more detailed view of inventory information for all switches (no hosts) on a networkwide basis.
Access these card from the Cumulus Workbench, or add them to your own workbench by clicking (Add card) > Inventory > Inventory|Devices card or Inventory|Switches card > Open Cards.
The NetQ CLI provides detailed network inventory information through its netq show inventory command.
View Networkwide Inventory Summary
All of the devices in your network can be viewed from either the NetQ UI or NetQ CLI.
View the Number of Each Device Type in Your Network
You can view the number of switches and hosts deployed in your network. As you grow your network this can be useful for validating that devices have been added as scheduled.
To view the quantity of devices in your network, locate or open the small or medium Inventory|Devices card. The medium-sized card provide operating system distribution across the network in addition to the device count.

View the Supported Cumulus Linux Packages
When you are troubleshooting an issue with a switch, you might want to know what versions of the Cumulus Linux operating system are supported on that switch and on a switch that is not having the same issue.
To view package information for your switches, run:
netq show cl-manifest [json]
This example shows the OS packages supported for all switches.
If you are having an issue with several switches, you may want to verify what software packages are installed on them and compare that to the recommended packages for a given Cumulus Linux release.
To view installed package information for your switches, run:
netq show cl-pkg-info [<text-package-name>] [around <text-time>] [json]
Use the text-package-name option to narrow the results to a particular package or the around option to narrow the output to a particular time range.
This example shows all installed software packages for all devices.

View Recommended Software Packages
You can determine whether any of your switches are using a software package other than the default package associated with the Cumulus Linux release that is running on the switches. Use this list to determine which packages to install/upgrade on all devices. Additionally, you can determine if a software package is missing.
To view recommended package information for your switches, run:
netq show recommended-pkg-version [release-id <text-release-id>] [package-name <text-package-name>] [json]
The output may be rather lengthy if this command is run for all releases and packages. If desired, run the command using the release-id and/or package-name options to shorten the output.
This example looks for switches running Cumulus Linux 3.7.1 and switchd. The result is a single switch, leaf12, that has older software and is recommended for update.

Monitor Switch Inventory
With the NetQ UI and NetQ CLI, you can monitor your inventory of switches across the network or individually. A user can monitor such items as operating system, motherboard, ASIC, microprocessor, disk, memory, fan and power supply information. Being able to monitor this inventory aids in upgrades, compliance, and other planning tasks.
The commands and cards available to obtain this type of information help you to answer questions such as:
What hardware is installed on my switch?
How many transmit and receive packets have been dropped?
The Cumulus NetQ UI provides the Inventory | Switches card for monitoring the hardware and software component inventory on switches running NetQ in your network. Access this card from the Cumulus Workbench, or add it to your own workbench by clicking (Add card) > Inventory > Inventory|Switches card > Open Cards.
The CLI provides detailed switch inventory information through its netq <hostname> show inventory command.

Component information for all of the switches in your network can be viewed from both the NetQ UI and NetQ CLI.
Inventory|Switches card:
Small: view count of switches and distribution of switch status
Medium: view count of OS, license, ASIC, platform, CPU model, Disk, and memory types or versions across all switches
netq show inventory command:
-View ASIC, CPU, disk, OS, and ports on all switches
View the Number of Types of Any Component Deployed
For each of the components monitored on a switch, NetQ displays the variety of those component by way of a count. For example, if you have three operating systems running on your switches, say Cumulus Linux, Ubuntu and RHEL, NetQ indicates a total unique count of three OSs. If you only use Cumulus Linux, then the count shows as one.
To view this count for all of the components on the switch:
Open the medium Switch Inventory card.
Note the number in the Unique column for each component.
In the above example, there are four different disk sizes deployed, four different OSs running, four different ASIC vendors and models deployed, and so forth.
Scroll down to see additional components.
By default, the data is shown for switches with a fresh communication status. You can choose to look at the data for switches in the rotten state instead. For example, if you wanted to see if there was any correlation to a version of OS to the switch having a rotten status, you could select Rotten Switches from the dropdown at the top of the card and see if they all use the same OS (count would be 1). It may not be the cause of the lack of communication, but you get the idea.
View the Distribution of Any Component Deployed
NetQ monitors a number of switch components. For each component you can view the distribution of versions or models or vendors deployed across your network for that component.
To view the distribution:
Locate the Inventory|Switches card on your workbench.
From the medium or large card, view the distribution of hardware and software components across the network.
Hover over any of the segments in the distribution chart to highlight a specific component. Scroll down to view additional components.
When you hover, a tooltip appears displaying:
Name or value of the component type, such as the version number or status
Total number of switches with that type of component deployed compared to the total number of switches
Percentage of this type with respect to all component types
On the large Switch Inventory card, hovering also highlights the related components for the selected component. This is shown in blue here.
Choose Rotten Switches from the dropdown to see which, if any, switches are currently not communicating with NetQ.
Return to your fresh switches, then hover over the card header and change to the small size card using the size picker.
Here you can see the total switch count and the distribution of those that are communicating well with the NetQ appliance or VM and those that are not. In this example, there are a total of 13 switches and they are all fresh (communicating well).
To view the hardware and software components for a switch, run:

View Recommended Software Packages
If you have a software manifest, you can determine what software packages and versions are recommended based on the Cumulus Linux release. You can then compare that to what is installed on your switch(es) to determine if it differs from the manifest. Such a difference might occur if one or more packages have been upgraded separately from the Cumulus Linux software itself.
To view recommended package information for a switch, run:
netq <hostname> show recommended-pkg-version [release-id <text-release-id>] [package-name <text-package-name>] [json]

Validate NetQ Agents are Running
You can confirm that NetQ Agents are running on switches and hosts (if installed) using the netq show agents command. Viewing the Status column of the output indicates whether the agent is up and current, labelled Fresh, or down and stale, labelled Rotten. Additional information is provided about the agent status, including whether it is time synchronized, how long it has been up, and the last time its state changed.
This example shows NetQ Agent state on all devices.
View the state of the NetQ Agent on a given device using the
hostname keyword.
View only the NetQ Agents that are fresh or rotten using the fresh or rotten keyword.
View the state of NetQ Agents at an earlier time using the around
keyword.
Monitor Software Services
Cumulus Linux and NetQ run a number of services to deliver the various features of these products. You can monitor their status using the netq show services command. The services related to system-level operation are described here. Monitoring of other services, such as those related to routing, are described with those topics. NetQ automatically monitors the following services:
bgpd: BGP (Border Gateway Protocol) daemon
clagd: MLAG (Multi-chassis Link Aggregation) daemon
mstpd: MSTP (Multiple Spanning Tree Protocol) daemon
neighmgrd: Neighbor Manager daemon for BGP and OSPF
netq-agent: NetQ Agent service
netqd: NetQ application daemon
ntp: NTP service
ntpd: NTP daemon
ptmd: PTM (Prescriptive Topology Manager) daemon
pwmd: PWM (Password Manager)
daemon
rsyslog: Rocket-fast system event logging processing service
smond: System monitor daemon
ssh: Secure Shell service for switches and servers
status: License validation service
syslog: System event logging service
vrf: VRF (Virtual Route Forwarding) service
zebra: GNU Zebra routing daemon
The CLI syntax for viewing the status of services is:
netq [<hostname>] show services [<service-name>] [vrf <vrf>] [active|monitored] [around <text-time>] [json]
netq [<hostname>] show services [<service-name>] [vrf <vrf>] status (ok|warning|error|fail) [around <text-time>] [json]
netq [<hostname>] show events [level info | level error | level warning | level critical | level debug] type services [between <text-time> and <text-endtime>] [json]
View All Services on All Devices
This example shows all of the available services on each device and whether each is enabled, active, and monitored, along with how long the service has been running and the last time it was changed.
It is useful to have colored output for this show command. To configure colored output, run the netq config add color command.
cumulus@switch:~$ netq show services

You can also view services information in JSON format:
If you want to view the service information for a given device, simply use the hostname option when running the command.
View Information about a Given Service on All Devices
You can view the status of a given service at the current time, at a prior point in time, or view the changes that have occurred for the service during a specified timeframe.
This example shows how to view the status of the NTP service across the network. In this case, VRF is configured so the NTP service runs on both the default and management interface. You can perform the same command with the other services, such as bgpd, lldpd, and clagd.

Monitor System Inventory
In addition to network and switch inventory, the Cumulus NetQ UI provides a view into the current status and configuration of the software network constructs in a tabular, networkwide view. These are helpful when you want to see all data for all of a particular element in your network for troubleshooting, or you want to export a list view.
Some of these views provide data that is also available through the card workflows, but these views are not treated like cards. They only provide the current status; you cannot change the time period of the views, or graph the data within the UI.
Access these tables through the Main Menu (), under the Network heading.
Tables can be manipulated using the settings above the tables, shown here and described in Table Settings.
Pagination options are shown when there are more than 25 results.

Monitor Container Environments Using Kubernetes API Server
The NetQ Agent monitors many aspects of containers on your network by integrating with the Kubernetes API server. In particular, the NetQ Agent tracks:
Identity: Every container’s IP and MAC address, name, image, and more. NetQ can locate containers across the fabric based on a container’s name, image, IP or MAC address, and protocol and port pair.
Port mapping on a network: Protocol and ports exposed by a container. NetQ can identify containers exposing a specific protocol and port pair on a network.
Connectivity: Information about network connectivity for a container, including adjacency, and can identify containers that can be affected by a top of rack switch.
This topic assumes a reasonable familiarity with Kubernetes terminology and architecture.
Use NetQ with Kubernetes Clusters
The NetQ Agent interfaces with the Kubernetes API server and listens to Kubernetes events. The NetQ Agent monitors network identity and physical network connectivity of Kubernetes resources like Pods, Daemon sets, Service, and so forth. NetQ works with any container network interface (CNI), such as Calico or Flannel.
The NetQ Kubernetes integration enables network administrators to:
Identify and locate pods, deployment, replica-set and services deployed within the network using IP, name, label, and so forth.
Track network connectivity of all pods of a service, deployment and replica set.
Locate what pods have been deployed adjacent to a top of rack (ToR) switch.
Check what pod, services, replica set or deployment can be impacted by a specific ToR switch.
NetQ also helps network administrators identify changes within a Kubernetes cluster and determine if such changes had an adverse effect on the network performance (caused by a noisy neighbor for example). Additionally, NetQ helps the infrastructure administrator determine how Kubernetes workloads are distributed within a network.
Requirements
The NetQ Agent supports Kubernetes version 1.9.2 or later.
Command Summary
There is a large set of commands available to monitor Kubernetes configurations, including the ability to monitor clusters, nodes, daemon-set, deployment, pods, replication, and services. Run netq show kubernetes help to see all the possible commands.
After waiting for a minute, run the show command to view the cluster.
cumulus@host:~$netq show kubernetes cluster
Next, you must enable the NetQ Agent on all of the worker nodes for complete insight into your container network. Repeat steps 2 and 3 on each worker node.
View Status of Kubernetes Clusters
Run the netq show kubernetes cluster command to view the status of all Kubernetes clusters in the fabric. In this example, we see there are two clusters; one with server11 as the master server and the other with server12 as the master server. Both are healthy and their associated worker nodes are listed.
cumulus@host:~$ netq show kubernetes cluster
Matching kube_cluster records:
Master Cluster Name Controller Status Scheduler Status Nodes

er12 server23 server
24
server12:3.0.0.69 default Healthy Healthy server12 server21 se
rver23 server13 serv
er14 server21 server
22
For deployments with multiple clusters, you can use the hostname option to filter the output. This example shows filtering of the list by server11:
cumulus@host:~$ netq server11 show kubernetes cluster
Matching kube_cluster records:
Master Cluster Name Controller Status Scheduler Status Nodes
------------------------ ---------------- -------------------- ---------------- --------------------

rver22 server11 serv
er12 server23 server
24
Optionally, use the json option to present the results in JSON format.
If data collection from the NetQ Agents is not occurring as it once was, you can verify that no changes have been made to the Kubernetes cluster configuration using the around option. Be sure to include the unit of measure with the around value. Valid units include:
w: week(s)
d: day(s)
h: hour(s)
m: minute(s)
s: second(s)
now
This example shows changes that have been made to the cluster in the last hour. In this example we see the addition of the two master nodes and the various worker nodes for each cluster.

View Kubernetes Pod Information
You can show configuration and status of the pods in a cluster, including the names, labels, addresses, associated cluster and containers, and whether the pod is running. This example shows pods for FRR, nginx, Calico, and various Kubernetes components sorted by master node.
You can view detailed information about a node, including their role in the cluster, pod CIDR and kubelet status. This example shows all of the nodes in the cluster with server11 as the master. Note that server11 acts as a worker node along with the other nodes in the cluster, server12, server13, server22, server23, and server24.
To display the kubelet or Docker version, use the components option with the show command. This example lists the kublet version, a proxy address if used, and the status of the container for server11 master and worker nodes.
To view only the details for a selected node, the name option with the hostname of that node following the components option:

View Status of the Replication Controller on a Node
When replicas have been created, you are then able to view information about the replication controller:
cumulus@host:~$ netq server11 show kubernetes replication-controller
No matching kube_replica records found
View Kubernetes Deployment Information
For each depolyment, you can view the number of replicas associated with an application. This example shows information for a deployment of the nginx application:
cumulus@host:~$ netq server11 show kubernetes deployment name nginx

Search Using Labels
You can search for information about your Kubernetes clusters using labels. A label search is similar to a “contains” regular expression search. In the following example, we are looking for all nodes that contain kube in the replication set name or label:
You can view the connectivity graph of a Kubernetes pod, seeing its replica set, deployment or service level. The connectivity graph starts with the server where the pod is deployed, and shows the peer for each server interface. This data is displayed in a similar manner as the netq trace command, showing the interface name, the outbound port on that interface, and the inbound port on the peer.
In this example shows connectivity at the deployment level, where the nginx-8586cf59-wjwgp replica is in a pod on the server22 node. It has four possible commumication paths, through interfaces swp1-4 out varying ports to peer interfaces swp7 and swp20 on torc-21, torc-22, edge01 and edge02 nodes. Similarly, the connections are shown for two additional nginx replicas.
You can show details about the Kubernetes services in a cluster, including service name, labels associated with the service, type of service, associated IP address, an external address if a public service, and ports used. This example show the services available in the Kubernetes cluster:
You can filter the list to view details about a particular Kubernetes service using the name option, as shown here:
cumulus@host:~$ netq show kubernetes service name calico-etcd

To see the connectivity of a given Kubernetes service, include the connectivity option. This example shows the connectivity of the calico-etcd service:
View the Impact of Connectivity Loss for a Service
You can preview the impact on the service availabilty based on the loss of particular node using the impact option. The output is color coded (not shown in the example below) so you can clearly see the impact: green shows no impact, yellow shows partial impact, and red shows full impact.
cumulus@host:~$ netq server11 show impact kubernetes service name calico-etcd

View Kubernetes Cluster Configuration in the Past
You can use the around option to go back in time to check the network status and identify any changes that occurred on the network.
This example shows the current state of the network. Notice there is a node named server23. server23 is there because the node server22 went down and Kubernetes spun up a third replica on a different host to satisfy the deployment requirement.
View the Impact of Connectivity Loss for a Deployment
You can determine the impact on the Kubernetes deployment in the event a host or switch goes down. The output is color coded (not shown in the example below) so you can clearly see the impact: green shows no impact, yellow shows partial impact, and red shows full impact.
Events provide information about how the network and its devices are operating. NetQ allows you to view current events and compare that with events at an earlier time. Event notifications are available through Slack, PagerDuty, syslog, and Email channels and aid troubleshooting and resolution of problems in the network before they become critical.
Three types of events are available in NetQ:
System: wide range of events generated by the system about network protocols and services operation, hardware and software status, and system services
Threshold-based (TCA): selected set of system-related events generated based on user-configured threshold values
What Just Happened (WJH): network hardware events generated when WJH feature is enabled on Mellanox switches
The NetQ UI provides two event workflows and and two summary tables:
Alarms card workflow: tracks critical severity system and TCA events for a given timeframe
Info card workflow: tracks all warning, info, and debug severity system and TCA events for a given timeframe
All Events table: lists all system events in the last 24 hours
What Just Happened table: lists the 1000 most recent WJH events in the last 24 hours
The NetQ CLI provides the netq show events command to view system and TCA events for a given timeframe. The netq show wjh-drop command lists all WJH events or those with a selected drop type.
To take advantage of these events, use the instructions contained in this topic to configure one or more notification channels for system and threshold-based events and setup WJH for selected switches.
Configure Notifications
To take advantage of the numerous event messages generated and processed by NetQ, you must integrate with third-party event notification applications. You can integrate NetQ with Syslog, PagerDuty, Slack, and Email. You may integrate with one or more of these applications simultaneously.
In an on-premises deployment, the NetQ On-premises Appliance or VM receives the raw data stream from the NetQ Agents, processes the data, stores, and delivers events to the Notification function. Notification then filters and sends messages to any configured notification applications. In a cloud deployment, the NetQ Cloud Appliance or VM passes the raw data stream on to the NetQ Cloud service for processing and delivery.
You may choose to implement a proxy server (that sits between the NetQ Appliance or VM and the integration channels) that receives, processes and distributes the notifications rather than having them sent directly to the integration channel. If you use such a proxy, you must configure NetQ with the proxy information.
Notifications are generated for the following types of events:

Text description of event
For example:
You can integrate notification channels using the NetQ UI or the NetQ CLI.
Channels card: specify channels
Threshold Crossing Rules card: specify rules and filters, assign existing channels
-netq notification (channel|rule|filter) command: specify channels, rules, and filters
To set up the integrations, you must configure NetQ with at least one channel, one rule, and one filter. To refine what messages you want to view and where to send them, you can add additional rules and filters and set thresholds on supported event types. You can also configure a proxy server to receive, process, and forward the messages. This is accomplished using the NetQ UI and NetQ CLI in the following order:
Configure Basic NetQ Event Notifications
The simplest configuration you can create is one that sends all events generated by all interfaces to a single notification application. This is described here. For more granular configurations and examples, refer to Configure Advanced NetQ Event Notifications.
A notification configuration must contain one channel, one rule, and one filter. Creation of the configuration follows this same path:
Add a channel.
Add a rule that accepts a selected set events.
Add a filter that associates this rule with the newly created channel.
Create a Channel
The first step is to create a PagerDuty, Slack, syslog, or Email channel to receive the notifications.
You can use the NetQ UI or the NetQ CLI to create a Slack channel.
Click , and then click Channels in the Notifications column.
The Slack tab is displayed by default.
Add a channel.
When no channels have been specified, click Add Slack Channel.
When at least one channel has been specified, click above the table.
Provide a unique name for the channel. Note that spaces are not allowed. Use dashes or camelCase instead.
Create an incoming webhook as described in the documentation for your version of Slack. Then copy and paste it here.
Click Add.
To verify the channel configuration, click Test.
Otherwise, click Close.
To return to your workbench, click in the top right corner of the card.
To create and verify the specification of a Slack channel, run:
cumulus@switch:~$ netq show notification channel

You can use the NetQ UI or the NetQ CLI to create an Email channel.
Click , and then click Channels in the Notifications column.
Click Email.
Add a channel.
When no channels have been specified, click Add Email Channel.
When at least one channel has been specified, click above the table.
Provide a unique name for the channel. Note that spaces are not allowed. Use dashes or camelCase instead.
Enter a list of emails for the persons who you want to receive the notifications from this channel.
Enter the emails separated by commas, and no spaces. For example: user1@domain.com,user2@domain.com,user3@domain.com.
The first time you configure an Email channel, you must also specify the SMTP server information:
Host: hostname or IP address of the SMTP server
Port: port of the SMTP server; typically 587
User ID/Password: your administrative credentials
From: email address that indicates who sent the event messages
After the first time, any additional email channels you create can use this configuration, by clicking Existing.
Click Add.
To verify the channel configuration, click Test.
Otherwise, click Close.
To return to your workbench, click in the top right corner of the card.
To create and verify the specification of an Email channel, run:
netq add notification channel email <text-channel-name> to <text-email-toids> [smtpserver <text-email-hostname>] [smtpport <text-email-port>] [login <text-email-id>] [password <text-email-password>] [severity info | severity warning | severity error | severity debug]
netq add notification channel email <text-channel-name> to <text-email-toids>
netq show notification channel [json]
The configuration is different depending on whether you are using the on-premises or cloud version of NetQ. No SMTP configuration is required for cloud deployments as the NetQ cloud service uses the NetQ SMTP server to push email notifications.
For an on-premises deployment:
Set up an SMTP server. The server can be internal or public.
Create a user account (login and password) on the SMTP server. Notifications are sent to this address.
Create the notification channel using this form of the CLI command:
This example creates a rule named all-interfaces, using the key ifname and the value ALL to indicate that all events from all interfaces should be sent to any channel with this rule.
cumulus@switch:~$ netq add notification rule all-interfaces key ifname value ALL
Successfully added/updated rule all-ifs
cumulus@switch:~$ netq show notification rule

If you want to create more granular notifications based on such items as selected devices, characteristics of devices, or protocols, or you want to use a proxy server, you need more than the basic notification configuration. Details for creating these more complex notification configurations are included here.
Configure a Proxy Server
To send notification messages through a proxy server instead of directly to a notification channel, you configure NetQ with the hostname and optionally a port of a proxy server. If no port is specified, NetQ defaults to port 80. Only one proxy server is currently supported. To simplify deployment, configure your proxy server before configuring channels, rules, or filters.

NetQ Notifier sends notifications to Slack as incoming webhooks for a
Slack channel you configure.
For example:
To create and verify the specification of a Slack channel, run:
WebHook URL for the desired channel. For example: https://hooks.slack.com/services/text/moretext/evenmoretext
severity <level>
The log level to set, which can be one of error, warning, info, or debug. The severity defaults to info.
tag <text-slack-tag>
Optional tag appended to the Slack notification to highlight particular channels or people. The tag value must be preceded by the @ sign. For example, @netq-info.
This example shows the creation of a slk-netq-events channel and verifies the configuration.
Create an incoming webhook as described in the documentation for your version of Slack.
This example creates an email channel named onprem-email that uses the smtpserver on port 587 to send messages to those persons with access to the smtphostlogin account.
Set up an SMTP server. The server can be internal or public.
Create a user account (login and password) on the SMTP server. Notifications are sent to this address.

Create Rules
Each rule is comprised of a single key-value pair. The key-value pair indicates what messages to include or drop from event information sent to a notification channel. You can create more than one rule for a single filter. Creating multiple rules for a given filter can provide a very defined filter. For example, you can specify rules around hostnames or interface names, enabling you to filter messages specific to those hosts or interfaces. You should have already defined channels (as described earlier).
There is a fixed set of valid rule keys. Values are entered as regular expressions and vary according to your deployment.

Rule names are case sensitive, and no wildcards are permitted. Rule names may contain spaces, but must be enclosed with single quotes in commands. It is easier to use dashes in place of spaces or mixed case for better readability. For example, use bgpSessionChanges or BGP-session-changes or BGPsessions, instead of 'BGP Session Changes'. Use Tab completion to view the command options syntax.

Create Filters
You can limit or direct event messages using filters. Filters are created based on rules you define; like those in the previous section. Each filter contains one or more rules. When a message matches the rule, it is sent to the indicated destination. Before you can create filters, you need to have already defined the rules and configured channels (as described earlier).
As filters are created, they are added to the bottom of a filter list. By default, filters are processed in the order they appear in this list (from top to bottom) until a match is found. This means that each event message is first evaluated by the first filter listed, and if it matches then it is processed, ignoring all other filters, and the system moves on to the next event message received. If the event does not match the first filter, it is tested against the second filter, and if it matches then it is processed and the system moves on to the next event received. And so forth. Events that do not match any filter are ignored.
You may need to change the order of filters in the list to ensure you capture the events you want and drop the events you do not want. This is possible using the before or after keywords to ensure one rule is processed before or after another.
This diagram shows an example with four defined filters with sample output results.
Filter names may contain spaces, but must be enclosed with single quotes in commands. It is easier to use dashes in place of spaces or mixed case for better readability. For example, use bgpSessionChanges or BGP-session-changes or BGPsessions, instead of 'BGP Session Changes'. Filter names are also case sensitive.
Example Filters
Create a filter for BGP Events on a Particular Device:
Create a Filter to Drop Messages from a Given Interface, and match
against this filter before any other filters. To create a drop style
filter, do not specify a channel. To put the filter first, use the
before option.
Use the netq show notification command to view the filters on your
platform.
cumulus@switch:~$ netq show notification filter

Reorder Filters
When you look at the results of the netq show notification filter command above, you might notice that although you have the drop-based filter first (no point in looking at something you are going to drop anyway, so that is good), but the critical severity events are processed last, per the current definitions. If you wanted to process those before
lesser severity events, you can reorder the list using the before and after options.
For example, to put the two critical severity event filters just below the drop filter:
You do not need to reenter all the severity, channel, and rule information for existing rules if you only want to change their processing order.
Run the netq show notification command again to verify the changes:

Suppress Events
Cumulus NetQ can generate many network events. You can configure whether to suppress any events from appearing in NetQ output. By default, all events are delivered.
You can suppress an event until a certain period of time; otherwise, the event is suppressed for 2 years. Providing an end time eliminates the generation of messages for a short period of time, which is useful when you are testing a new network configuration and the switch may be generating many messages.
You can suppress events for the following types of messages:
agent: NetQ Agent messages
bgp: BGP-related messages
btrfsinfo: Messages related to the BTRFS file system in Cumulus Linux
clag: MLAG-related messages
clsupport: Messages generated when creating the cl-support script
configdiff: Messages related to the difference between two configurations
evpn: EVPN-related messages
link: Messages related to links, including state and interface name
ntp: NTP-related messages
ospf: OSPF-related messages
sensor: Messages related to various sensors
services: Service-related information, including whether a service is active or inactive
ssdutil: Messages related to the storage on the switch
Add an Event Suppression Configuration
When you add a new configuration, you can specify a scope, which limits the suppression in the following order:
Hostname.
Severity.
Message type-specific filters. For example, the target VNI for EVPN messages, or the interface name for a link message.
NetQ has a predefined set of filter conditions. To see these conditions, run netq show events-config show-filter-conditions:
cumulus@switch:~$ netq show events-config show-filter-conditions

For example, to create a configuration called mybtrfs that suppresses OSPF-related events on leaf01 for the next 10 minutes, run:
If you are filtering for a message type, you must include the show-filter-conditions keyword to show the conditions associated with that message type and the hierarchy in which they’re processed.
Putting all of these channel, rule, and filter definitions together you
create a complete notification configuration. The following are example
notification configurations are created using the three-step process
outlined above.
Create a Notification for BGP Events from a Selected Switch
In this example, we created a notification integration with a PagerDuty
channel called pd-netq-events. We then created a rule bgpHostname
and a filter called 4bgpSpine for any notifications from spine-01.
The result is that any info severity event messages from Spine-01 are
filtered to the pd-netq-events channel.

Create a Notification for Warnings on a Given EVPN VNI
In this example, we created a notification integration with a PagerDuty
channel called pd-netq-events. We then created a rule evpnVni and a
filter called 3vni42 for any warnings messages from VNI 42 on the EVPN
overlay network. The result is that any warning severity event messages
from VNI 42 are filtered to the pd-netq-events channel.

Create a Notification for Configuration File Changes
In this example, we created a notification integration with a Slack
channel called slk-netq-events. We then created a rule sysconf and a
filter called configChange for any configuration file update messages.
The result is that any configuration update messages are filtered to the
slk-netq-events channel.

In this example, we created a notification integration with a Slack
channel called slk-netq-events. We then created a rule svcStatus and
a filter called svcDown for any services state messages indicating a
service is no longer operational. The result is that any service down
messages are filtered to the slk-netq-events channel.

Create a Filter to Drop Notifications from a Given Interface
In this example, we created a notification integration with a Slack
channel called slk-netq-events. We then created a rule swp52 and a
filter called swp52Drop that drops all notifications for events from
interface swp52.

Create a Notification for a Given Device that has a Tendency to Overheat (using multiple rules)
In this example, we created a notification when switch leaf04 has
passed over the high temperature threshold. Two rules were needed to
create this notification, one to identify the specific device and one to
identify the temperature trigger. We sent the message to the
pd-netq-events channel.

View Notification Configurations in JSON Format
You can view configured integrations using the netq show notification commands. To view the channels, filters, and rules, run the three flavors of the command. Include the json option to display JSON-formatted output.
You might need to modify event notification configurations at some point in the lifecycle of your deployment. You can add and remove channels, rules, filters, and a proxy at any time.
For integrations with threshold-based event notifications, refer to Configure Notifications.
Remove an Event Notification Channel
If you retire selected channels from a given notification appliacation, you might want to remove them from NetQ as well. You can remove channels using the NetQ UI or the NetQ CLI.
To remove notification channels:
Click , and then click Channels in the Notifications column.
This opens the Channels view.
Click the tab for the type of channel you want to remove (Slack, PagerDuty, Syslog, Email).
Select one or more channels.
Click .
To remove notification channels, run:
netq config del notification channel <text-channel-name-anchor>
This example removes a Slack integration and verifies it is no longer in
the configuration:
cumulus@switch:~$ netq del notification channel slk-netq-events

Delete an Event Notification Proxy
You can remove the proxy server by running the netq del notification proxy command. This changes the NetQ behavior to send events directly to the notification channels.
cumulus@switch:~$ netq del notification proxy

Configure Threshold-based Event Notifications
NetQ supports a set of events that are triggered by crossing a user-defined threshold, called TCA events. These events allow detection and prevention of network failures for selected interface, utilization, sensor, forwarding, ACL and digital optics events.
A notification configuration must contain one rule. Each rule must contain a scope and a threshold. Optionally, you can specify an associated channel. Note: If a rule is not associated with a channel, the event information is only reachable from the database. If you want to deliver events to one or more notification channels (Email, syslog, Slack, or PagerDuty), create them by following the instructions in Create a Channel, and then return here to define your rule.

Create a TCA Rule
Now that you know which events are supported and how to set the scope, you can create a basic rule to deliver one of the TCA events to a notification channel. This can be done using either the NetQ UI or the NetQ CLI.
To create a TCA rule:
Click to open the Main Menu.
Click Threshold Crossing Rules under Notifications.
Click to add a rule.
The Create TCA Rule dialog opens. Four steps create the rule.
You can move forward and backward until you are satisfied with your rule definition.
On the Enter Details step, enter a name for your rule, choose your TCA event type, and assign a severity.
The rule name has a maximum of 20 characters (including spaces).
Click Next.
On the Choose Attribute step, select the attribute to measure against.
The attributes presented depend on the event type chosen in the Enter Details step. This example shows the attributes available when Resource Utilization was selected.
Click Next.
On the Set Threshold step, enter a threshold value.
For Digital Optics, you can choose to use the thresholds defined by the optics vendor (default) or specify your own.
Define the scope of the rule.
If you want to restrict the rule to a particular device, and enter values for one or more of the available parameters.
If you want the rule to apply to all devices, click the scope toggle.
Click Next.
Optionally, select a notification channel where you want the events to be sent.
Only previously created channels are available for selection. If no channel is available or selected, the notifications can only be retrieved from the database. You can add a channel at a later time and then add it to the rule. Refer to Create a Channel and Modify TCA Rules.
Click Finish.
This example shows four rules. The rule on the left triggers an alarm event when the laser bias current exceeds the upper threshold set by the vendor on all interfaces of all leaf switches. The rule second to the left triggers an alarm event when the temperature on the temp1 sensor exceeds 32 °C on the all leaf switch. The rule second to the right triggers an alarm event when any device exceeds the maximum CPU utilization of 93%. The rule on the right triggers an informational event when switch leaf01 exceeds the maximum CPU utilization of 87%. Note that the cards indicate all rules are currently Active.
The simplest configuration you can create is one that sends a TCA event generated by all devices and all interfaces to a single notification application. Use the netq add tca command to configure the event. Its syntax is:
Note that the event ID is case sensitive and must be in all uppercase.
For example, this rule tells NetQ to deliver an event notification to the tca_slack_ifstats pre-configured Slack channel when the CPU utilization exceeds 95% of its capacity on any monitored switch:
This rule tells NetQ to deliver an event notification to the tca_pd_ifstats PagerDuty channel when the number of transmit bytes per second (Bps) on the leaf12 switch exceeds 20,000 Bps on any interface:
This rule tells NetQ to deliver an event notification to the syslog-netq syslog channel when the temperature on sensor temp1 on the leaf12 switch exceeds 32 degrees Celcius:
For a Slack channel, the event messages should be similar to this:
Set the Severity of a Threshold-based Event
In addition to defining a scope for TCA rule, you can also set a severity of either info or critical. To add a severity to a rule, use the severity option.
For example, if you want to add a critical severity to the CPU utilization rule you created earlier:
Digital optics have the additional option of applying user- or vendor-defined thresholds, using the threshold_type and threshold options.
This example shows how to send an alarm event on channel ch1 when the upper threshold for module voltage exceeds the vendor-defined thresholds for interface swp31 on the mlx-2700-04 switch.
This example shows how to send an alarm event on channel ch1 when the upper threshold for module voltage exceeds the user-defined threshold of 3V for interface swp31 on the mlx-2700-04 switch.
Now you have four rules created (the original one, plus these three new ones) all based on the TCA_SENSOR_TEMPERATURE_UPPER event. To identify the various rules, NetQ automatically generates a TCA name for each rule. As each rule is created, an _# is added to the event name. The TCA Name for the first rule created is then TCA_SENSOR_TEMPERATURE_UPPER_1, the second rule created for this event is TCA_SENSOR_TEMPERATURE_UPPER_2, and so forth.
Manage Threshold-based Event Notifications
Once you have created a bunch of rules, you might want to modify them; view a list of the rules, disable a rule, delete a rule, and so forth.
View TCA Rules
You can view all of the threshold-crossing event rules you have created in the NetQ UI or the NetQ CLI.
Click .
Select Threshold Crossing Rules under Notifications.
A card is displayed for every rule.
To view TCA rules, run:
netq show tca [tca_id <text-tca-id-anchor>] [json]
This example displays all TCA rules:
cumulus@switch:~$ netq show tca

Change, Add, or Remove the Channels on a TCA Rule
Click to open the Main Menu.
Click Threshold Crossing Rules under Notifications.
Locate the rule you want to modify and hover over the card.
Click .
Click Channels.
Select one or more channels.
Click a channel to select it. Click again to unselect a channel.
You cannot change the name of a TCA rule using the NetQ CLI because the rules are not named. They are given identifiers (tca_id) automatically. In the NetQ UI, to change a rule name, you must delete the rule and re-create it with the new name. Refer to Delete a TCA Rule and then Create a TCA Rule.
Change the Severity of a TCA Rule
TCA rules have either an informational or critical severity.
In the NetQ UI, the severity cannot be changed by itself, the rule must be deleted and re-created using the new severity. Refer to Delete a TCA Rule and then Create a TCA Rule.
In the NetQ CLI, to change the severity, run:
netq add tca tca_id <text-tca-id-anchor> (severity info | severity critical)
This example changes the severity of the maximum CPU utilization 1 rule from critical to info:
During troubleshooting or maintenance of switches you may want to suppress a rule to prevent erroneous event messages. This can be accomplished using the NetQ UI or the NetQ CLI.
The TCA rules have three possible states iin the NetQ UI:
Active: Rule is operating, delivering events. This would be the normal operating state.
Suppressed: Rule is disabled until a designated date and time. When that time occurs, the rule is automatically reenabled. This state is useful during troubleshooting or maintenance of a switch when you do not want erroneous events being generated.
Disabled: Rule is disabled until a user manually reenables it. This state is useful when you are unclear when you want the rule to be reenabled. This is not the same as deleting the rule.
To suppress a rule for a designated amount of time, you must change the state of the rule.
To suppress a rule:
Click to open the Main Menu.
Click Threshold Crossing Rules under Notifications.
Locate the rule you want to suppress.
Click Disable.
Click in the Date/Time field to set when you want the rule to be automatically reenabled.
Click Disable.
Note the changes in the card:
The state is now marked as Inactive, but remains green
The date and time that the rule will be enabled is noted in the Suppressed field
The Disable option has changed to Disable Forever. Refer to Disable a TCA Rule for information about this change.
Using the suppress_until option allows you to prevent the rule from being applied for a designated amout of time (in seconds). When this time has passed, the rule is automatically reenabled.
Whereas suppression temporarily disables a rule, you can deactivate a rule to disable it indefinitely. You can disable a rule using the NetQ UI or the NetQ CLI.
The TCA rules have three possible states in the NetQ UI:
Active: Rule is operating, delivering events. This would be the normal operating state.
Suppressed: Rule is disabled until a designated date and time. When that time occurs, the rule is automatically reenabled. This state is useful during troubleshooting or maintenance of a switch when you do not want erroneous events being generated.
Disabled: Rule is disabled until a user manually reenables it. This state is useful when you are unclear when you want the rule to be reenabled. This is not the same as deleting the rule.
To disable a rule that is currently active:
Click to open the Main Menu.
Click Threshold Crossing Rules under Notifications.
Locate the rule you want to disable.
Click Disable.
Leave the Date/Time field blank.
Click Disable.
Note the changes in the card:
The state is now marked as Inactive and is red
The rule definition is grayed out
The Disable option has changed to Enable to reactivate the rule when you are ready
To disable a rule that is currently suppressed:
Click to open the Main Menu.
Click Threshold Crossing Rules under Notifications.
Locate the rule you want to disable.
Click Disable Forever.
Note the changes in the card:
The state is now marked as Inactive and is red
The rule definition is grayed out
The Disable option has changed to Enable to reactivate the rule when you are ready
To reenable the rule, set the is_active option to true.
Delete a TCA Rule
You might find that you no longer want to receive event notifications for a particular TCA event. In that case, you can either disable the event if you think you may want to receive them again or delete the rule altogether. Refer to Disable a Rule for the first case. Follow the instructions here to remove the rule using either the NetQ UI or NetQ CLI.
The rule can be in any of the three states, active, suppressed, or disabled.
To delete a rule:
Click to open the Main Menu.
Click Threshold Crossing Rules under Notifications.
Locate the rule you want to remove and hover over the card.
Click .
To remove a rule altogether, run:
netq del tca tca_id <text-tca-id-anchor>
This example deletes the maximum receive bytes rule:
cumulus@switch:~$ netq del tca tca_id TCA_RXBYTES_UPPER_1
Successfully deleted TCA TCA_RXBYTES_UPPER_1
Resolve Scope Conflicts
There may be occasions where the scope defined by the multiple rules for a given TCA event may overlap each other. In such cases, the TCA rule with the most specific scope that is still true is used to generate the event.
To clarify this, consider this example. Three events have occurred:
First event on switch leaf01, interface swp1
Second event on switch leaf01, interface swp3
Third event on switch spine01, interface swp1
NetQ attempts to match the TCA event against hostname and interface name with three TCA rules with different scopes:
Scope 1 send events for the swp1 interface on switch leaf01 (very specific)
Scope 2 send events for all interfaces on switches that start with leaf (moderately specific)
Scope 3 send events for all switches and interfaces (very broad)
The result is:
For the first event, NetQ applies the scope from rule 1 because it matches scope 1 exactly
For the second event, NetQ applies the scope from rule 2 because it does not match scope 1, but does match scope 2
For the third event, NetQ applies the scope from rule 3 because it does not match either scope 1 or scope 2
In summary:

Monitor System and TCA Events
NetQ offers multiple ways to view your event status. The NetQ UI provides a graphical and tabular view and the NetQ CLI provides a tabular view of system and threshold-based (TCA) events. System events include events associated with network protocols and services operation, hardware and software status, and system services. TCA events include events associated with digital optics, ACL and forwarding resources, interface statistics, resource utilization, and sensors. You can view all events across the entire network or all events on a device. For each of these, you can filter your view of events based on event type, severity, and timeframe.
Refer to Configure Notifications for information about configuring and managing these events.
Refer to the NetQ UI Card Reference for details of the cards used with the following procedures.

View Alarm Status Summary
A summary of the critical alarms in the network includes the number of alarms, a trend indicator, a performance indicator, and a distribution of those alarms.
To view the summary, open the small Alarms card.
In this example, there are a small number of alarms (2), the number of alarms is decreasing (down arrow), and there are fewer alarms right now than the average number of alarms during this time period. This would indicate no further investigation is needed. Note that with such a small number of alarms, the rating may be a bit skewed.
View the Distribution of Alarms
It is helpful to know where and when alarms are occurring in your network. The Alarms card workflow enables you to see the distribution of alarms based on its source: network services, interfaces, system services, and threshold-based events.
To view the alarm distribution, open the medium Alarms card. Scroll down to view all of the charts.
Monitor Alarm Details
The Alarms card workflow enables users to easily view and track critical severity alarms occurring anywhere in your network. You can sort alarms based on their occurrence or view devices with the most network services alarms.
To view critical alarms, open the large Alarms card.
From this card, you can view the distribution of alarms for each of the categories over time. The charts are sorted by total alarm count, with the highest number of alarms in a category listed at the top. Scroll down to view any hidden charts. A list of the associated alarms is also displayed. By default, the list of the most recent alarms is displayed when viewing the large card.
View Devices with the Most Alarms
You can filter instead for the devices that have the most alarms.
To view devices with the most alarms, open the large Alarms card, and then select Devices by event count from the dropdown.
You can open the switch card for any of the listed devices by clicking on the device name.
Filter Alarms by Category
You can focus your view to include alarms for one or more selected alarm categories.
To filter for selected categories:
Click the checkbox to the left of one or more charts to remove that set of alarms from the table on the right.
Select the Devices by event count to view the devices with the most alarms for the selected categories.
Switch back to most recent events by selecting Events by most recent.
Click the checkbox again to return a category’s data to the table.
In this example, we removed the Services from the event listing.
Compare Alarms with a Prior Time
You can change the time period for the data to compare with a prior time. If the same devices are consistently indicating the most alarms, you might want to look more carefully at those devices using the Switches card workflow.
To compare two time periods:
Open a second Alarm Events card. Remember it goes to the bottom of the workbench.
Switch to the large size card.
Move the card to be next to the original Alarm Events card. Note that moving large cards can take a few extra seconds since they contain a large amount of data.
Hover over the card and click .
Select a different time period.
Compare the two cards with the Devices by event count filter applied.
In this example, the total alarm count and the devices with the most alarms in each time period have changed for the better overall. You could go back further in time or investigate the current status of the largest offenders.
View All Alarm Events
You can view all events in the network either by clicking the Show All Events link under the table on the large Alarm Events card, or by opening the full screen Alarm Events card.
OR
To return to your workbench, click in the top right corner of the card.
View Info Status Summary
A summary of the informational events occurring in the network can be found on the small, medium, and large Info cards. Additional details are available as you increase the size of the card.
To view the summary with the small Info card, simply open the card. This card gives you a high-level view in a condensed visual, including the number and distribution of the info events along with the alarms that have occurred during the same time period.
To view the summary with the medium Info card, simply open the card. This card gives you the same count and distribution of info and alarm events, but it also provides information about the sources of the info events and enables you to view a small slice of time using the distribution charts.
Use the chart at the top of the card to view the various sources of info events. The four or so types with the most info events are called out separately, with all others collected together into an Other category. Hover over segment of chart to view the count for each type.
To view the summary with the large Info card, open the card. The left side of the card provides the same capabilities as the medium Info card.
Compare Timing of Info and Alarm Events
While you can see the relative relationship between info and alarm events on the small Info card, the medium and large cards provide considerably more information. Open either of these to view individual line charts for the events. Generally, alarms have some corollary info events. For example, when a network service becomes unavailable, a critical alarm is often issued, and when the service becomes available again, an info event of severity warning is generated. For this reason, you might see some level of tracking between the info and alarm counts and distributions. Some other possible scenarios:
When a critical alarm is resolved, you may see a temporary increase in info events as a result.
When you get a burst of info events, you may see a follow-on increase in critical alarms, as the info events may have been warning you of something beginning to go wrong.
You set logging to debug, and a large number of info events of severity debug are seen. You would not expect to see an increase in critical alarms.
View All Info Events Sorted by Time of Occurrence
You can view all info events using the large Info card. Open the large card and confirm the Events By Most Recent option is selected in the filter above the table on the right. When this option is selected, all of the info events are listed with the most recently occurring event at the top. Scrolling down shows you the info events that have occurred at an earlier time within the selected time period for the card.
View Devices with the Most Info Events
You can filter instead for the devices that have the most info events by selecting the Devices by Event Count option from the filter above the table.
You can open the switch card for any of the listed devices by clicking on the device name.
View All Info Events
You can view all events in the network either by clicking the Show All Events link under the table on the large Info Events card, or by opening the full screen Info Events card.
OR
System events
System and TCA events
To return to your workbench, click in the top right corner of the card.

All system and TCA events across the network between midnight and 11:30am
All cards have a default time period for the data shown on the card, typically the last 24 hours. You can change the time period to view the data during a different time range to aid analysis of previous or existing issues. You can also compare the current events with a prior time. If the same devices are consistently indicating the most alarms, you might want to look more carefully at those devices using the Switches card workflow.
To view critical events for a time in the past using the small, medium, or large Events|Alarms card:
Locate or open the Events|Alarms card on your workbench.
Hover over the card, and click in the header.

Configure and Monitor What Just Happened Metrics
The What Just Happened (WJH) feature, available on Mellanox switches, streams detailed and contextual telemetry data for analysis. This provides real-time visibility into problems in the network, such as hardware packet drops due to buffer congestion, incorrect routing, and ACL or layer 1 problems. You must have Cumulus Linux 4.0.0 or later and NetQ 2.4.0 or later to take advantage of this feature.
If your switches are sourced from a vendor other than Mellanox, this view is blank as no data is collected.
When WJH capabilities are combined with Cumulus NetQ, you have the ability to hone in on losses, anywhere in the fabric, from a single management console. You can:
View any current or historic drop information, including the reason for the drop
Identify problematic flows or endpoints, and pin-point exactly where communication is failing in the network
By default, Cumulus Linux 4.0.0 provides the NetQ 2.3.1 Agent and CLI. If you installed Cumulus Linux 4.0.0 on your Mellanox switch, you need to upgrade the NetQ Agent and optionally the CLI to release 2.4.0 or later (preferably the latest release).
WJH is enabled by default on Mellanox switches and no configuration is required in Cumulus Linux 4.0.0; however, you must enable the NetQ Agent to collect the data in NetQ 2.4.0 or later.
To enable WJH in NetQ:
Configure the NetQ Agent on the Mellanox switch.
cumulus@switch:~$ netq config add agent wjh
Restart the NetQ Agent to start collecting the WJH data.
cumulus@switch:~$ netq config restart agent
When you are finished viewing the WJH metrics, you might want to stop the NetQ Agent from collecting WJH data to reduce network traffic. Use netq config del agent wjh followed by netq config restart agent to disable the WJH feature on the given switch.
Using wjh_dump.py on a Mellanox platform that is running Cumulus Linux 4.0 and the NetQ 2.4.0 agent causes the NetQ WJH client to stop receiving packet drop call backs. To prevent this issue, run wjh_dump.py on a different system than the one where the NetQ Agent has WJH enabled, or disable wjh_dump.py and restart the NetQ Agent (run netq config restart agent).
Configure Latency and Congestion Thresholds
WJH latency and congestion metrics depend on threshold settings to trigger the events. Packet latency is measured as the time spent inside a single system (switch). Congestion is measured as a percentage of buffer occupancy on the switch. When WJH triggers events when the high and low thresholds are crossed.
You can view the WJH metrics from the NetQ UI or the NetQ CLI.
Click (main menu).
Click What Just Happened under the Network column.
This view displays events based on conditions detected in the data plane. The most recent 1000 events from the last 24 hours are presented for each drop category.
By default the layer 1 drops are shown. Click one of the other drop categories to view those drops for all devices.
Use the various options to restrict the output accordingly.
This example uses the first form of the command to show drops on switch leaf03 for the past week.

Monitor Operations
After the network has been deployed, the day-to-day tasks of monitoring the devices, protocols and services begin. The topics in this section provide instructions for monitoring:
Switches and hosts
Physical, data link, network, and application layer protocols and services
Overlay network protocols
Additionally, this section provides instructions for monitoring devices and the network using a topology view.
With the NetQ UI and CLI, a user can monitor the network inventory of switches and hosts, including such items as the number of each and what operating systems are installed. Additional details are available about the hardware and software components on individual switches, such as the motherboard, ASIC, microprocessor, disk, memory, fan and power supply information. The commands and cards available to obtain this type of information help you to answer questions such as:
What switches do I have in the network?
Do all switches have valid licenses?
Are NetQ agents running on all of my switches?
How many transmit and receive packets have been dropped?
How healthy are the fans and power supply?
What software is installed on my switches?
What is the ACL and forwarding resources usage?
Monitor Switch Performance
With the NetQ UI and NetQ CLI, you can monitor the health of individual switches, including interface performance and resource utilization.
Three categories of performance metrics are available for switches:
System configuration: alarms, interfaces, IP and MAC addresses, VLANs, IP routes, IP neighbors, and installed software packages
Utilization statistics: CPU, memory, disk, ACL and forwarding resources, SSD, and BTRFS
Physical sensing: digital optics and chassis sensors
For information about the health of network services and protocols (BGP, EVPN, NTP, and so forth) running on switches, refer to the relevant layer monitoring topic.
For switch inventory information for all switches (ASIC, platform, CPU, memory, disk, and OS), refer to Monitor Switch Inventory.
View Overall Health
The NetQ UI provides several views that enable users to easily track the overall health of switch, some high-level metrics, and attributes of the switch.
View Overall Health of a Switch
When you want to view an overview of the current or past health of a particular switch, open the NetQ UI small Switch card. It is unlikely that you would have this card open for every switch in your network at the same time, but it is useful for tracking selected switches that may have been problematic in the recent past or that you have recently installed. The card shows you alarm status, a summary health score, and health trend.
To view the summary:
Click (Switches), then click Open a switch card.
Begin typing the hostname of the switch you are interested in. Select it from the suggested matches when it appears.
Select Small from the card size dropdown.
Click Add.
This example shows the leaf01 switch has had very few alarms overall, but the number is trending upward, with a total count of 24 alarms currently.
View High-Level Health Metrics
When you are monitoring switches that have been problematic or are newly installed, you might want to view more than a summary. Instead, seeing key performance metrics can help you determine where issues might be occurring or how new devices are functioning in the network.
To view the key metrics, use the NetQ UI to open the medium Switch card. The card shows you the overall switch health score and the scores for the key metrics that comprise that score. The key metric scores are based on the number of alarms attributed to the following activities on the switch:
Network services, such as BGP, EVPN, MLAG, NTP, and so forth
Interface performance
System performance
Locate or open the relevant Switch card:
Click (Switches), then click Open a switch card.
Begin typing the hostname of the device you are interested in. Select it from the suggested matches when it appears.
Click Add.
Also included on the card is the total alarm count for all of these metrics. You can view the key performance metrics as numerical scores or as line charts over time, by clicking Alarms or Charts at the top of the card.
View Switch Attributes
For a quick look at the key attributes of a particular switch, open the large Switch card.
Locate or open the relevant Switch card:
Hover over the card, then change to the large card using the card size picker.
OR
Click (Switches), then click Open a switch card.
Begin typing the hostname of the device you are interested in. Select it from the suggested matches when it appears.
Select Large from the card size dropdown.
Click Add.
Attributes are displayed as the default tab on the large Switch card. You can view the static information about the switch, including its hostname, addresses, server and ASIC vendors and models, OS and NetQ software information. You can also view the state of the interfaces, NetQ Agent, and license on the switch.
From a performance perspective, this example shows that five interfaces are down, the NetQ Agent is communicating with the NetQ appliance or VM, and it is missing the Cumulus Linux license. It is important the license is valid, so you would want to fix this first (refer to Install the Cumulus Linux License. Secondly, you would want to look more closely at the interfaces (refer to interface statistics).
System Configuration
At some point in the lifecycle of a switch, you are likely to want more detail about how the switch is configured and what software is running on it. The NetQ UI and the NetQ CLI can provide this information.
View All Switch Alarms
You can focus on all critical alarms for a given switch using the NetQ UI or NetQ CLI.
To view all alarms:
Open the full-screen Switch card and click Alarms.
Use the filter to sort by message type.
Use the filter to look at alarms during a different time range.
Return to your workbench by clicking in the top right corner.
To view all critical alarms on the switch, run:
netq <hostname> show events level critical [between <text-time> and <text-endtime>] [json]
This example shows the critical alarms on spine01 in the last two months.
cumulus@switch:~$ netq spine01 show events level critical between now and 60d
Matching events records:

spine01 agent critical Netq-agent rebooted at (Mon Aug 10 Mon Aug 10 19:55:19 2020
19:55:07 UTC 2020)
View Status of All Interfaces
You can view all of the configured interfaces on a switch in one place making it easier to see inconsistencies in the configuration, quickly see when changes were made, and the operational status.
To view all interfaces:
Open the full-screen Switch card and click All Interfaces.
Look for interfaces that are down, shown in the State column.
Look for recent changes to the interfaces, shown in the Last Changed column.
View details about each interface, shown in the Details column.
Verify they are of the correct kind for their intended function, shown in the Type column.
Verify the correct VRF interface is assigned to an interface, shown in the VRF column.
To return to the workbench, click in the top right corner.
You can view all interfaces or filter by the interface type.
You can view all MAC address currently used by a switch using the NetQ UI or the NetQ CLI.
Open the full-screen switch card for the switch of interest.
Review the addresses.
Optionally, click to filter by MAC address, VLAN, origin, or alternate time range.
You can view all MAC addresses on a switch, or filter the list to view a particular address, only the addresses on the egress port, a particular VLAN, or those that are owned by the switch. You can also view the number addresses.
Use the following commands to obtain this MAC address information:
This example shows all of the MAC addresses on the leaf01 switch:
cumulus@switch:~$ netq leaf01 show macs
Matching mac records:

Utilization Statistics
Utilization statistics provide a view into the operation of a switch. They indicate whether resources are becoming dangerously close to their maximum capacity or a user-defined threshold. Depending on the function of the switch, the acceptable thresholds can vary. You can use the NetQ UI or the NetQ CLI to access the utilization statistics.
View Compute Resources Utilization
You can view the current utilization of CPU, memory, and disk resources to determine whether a switch is reaching its maximum load and compare its performance with other switches.
To view the compute resources utilization:
Open the large Switch card.
Hover over the card and click .
The card is divided into two sections, displaying hardware-related performance through a series of charts.
Look at the hardware performance charts.
Are there any that are reaching critical usage levels? Is usage high at a particular time of day?
Change the time period. Is the performance about the same? Better? Worse? The results can guide your decisions about upgrade options.
Open the large Switch card for a comparable switch. Is the performance similar?
You can quickly determine how many compute resources — CPU, disk and memory — are being consumed by the switches on your network.
To obtain this information, run the relevant command:
netq <hostname> show resource-util [cpu | memory] [around <text-time>] [json]
netq <hostname> show resource-util disk [<text-diskname>] [around <text-time>] [json]
When no options are included the output shows the percentage of CPU and memory being consumed as well as the amount and percentage of disk space being consumed. You can use the around option to view the information for a particular time.
This example shows the CPU, memory, and disk utilization for the leaf01 switch.

View Interface Statistics and Utilization
NetQ Agents collect performance statistics every 30 seconds for the physical interfaces on switches in your network. The NetQ Agent does not collect statistics for non-physical interfaces, such as bonds, bridges, and VXLANs. The NetQ Agent collects the following statistics:
You can view these statistics and utilization data using the NetQ UI or the NetQ CLI.
Locate the switch card of interest on your workbench and change to the large size card if needed. Otherwise, open the relevant switch card:
Click (Switches), and then select Open a switch card.
Begin typing the name of the switch of interest, and select when it appears in the suggestions list.
Select the Large card size.
Click Add.
Hover over the card and click to open the Interface Stats tab.
Select an interface from the list, scrolling down until you find it. By default the interfaces are sorted by Name, but you may find it easier to sort by the highest transmit or receive utilization using the filter above the list.
The charts update according to your selection. Scroll up and down to view the individual statistics. Look for high usage, a large number of drops or errors.
What you view next depends on what you see, but a couple of possibilities include:
Open the full screen card to view details about all of the interfaces on the switch.
Open another switch card to compare performance on a similar interface.
To view the interface statistics and utilization, run:
netq <hostname> show interface-stats [errors | all] [<physical-port>] [around <text-time>] [json]
netq <hostname> show interface-utilization [<text-port>] [tx|rx] [around <text-time>] [json]
Where the various options are:

You can monitor the incoming and outgoing access control lists (ACLs) configured on a switch. This ACL resource information is available from the NetQ UI and NetQ CLI.
Both the Switch card and netq show cl-resource acl command display the ingress/egress IPv4/IPv6 filter/mangle, ingress 802.1x filter, ingress mirror, ingress/egress PBR IPv4/IPv6 filter/mangle, ACL Regions, 18B/32B/54B Rules Key, and L4 port range checker.
To view ACL resource utilization on a switch:
Open the Switch card for a switch by searching in the Global Search field.
Hover over the card and change to the full-screen card using the size picker.
Click ACL Resources.
To return to your workbench, click in the top right corner of the card.
To view ACL resource utilization on a switch, run:
For NetQ Appliances that have 3ME3 solid state drives (SSDs) installed (primarily in on-premises deployments), you can view the utilization of the drive on-demand. An alarm is generated for drives that drop below 10% health, or have more than a two percent loss of health in 24 hours, indicating the need to rebalance the drive. Tracking SSD utilization over time enables you to see any downward trend or instability of the drive before you receive an alarm.
To view SSD utilization:
Open the full screen Switch card and click SSD Utilization.
View the average PE Cycles value for a given drive. Is it higher than usual?
View the Health value for a given drive. Is it lower than usual? Less than 10%?
Consider adding the switch cards that are suspect to a workbench for easy tracking.
To view SDD utilization, run:
netq <hostname> show cl-ssd-util [around <text-time>] [json]
This example shows the utilization for spine02 which has this type of SSD.
cumulus@switch:~$ netq spine02 show cl-ssd-util
Hostname Remaining PE Cycle (%) Current PE Cycles executed Total PE Cycles supported SSD Model Last Changed
spine02 80 576 2880 M.2 (S42) 3ME3 Thu Oct 31 00:15:06 2019
This output indicates that this drive is in a good state overall with 80% of its PE cycles remaining. Use the around option to view this information around a particular time in the past.
View Disk Storage After BTRFS Allocation
Customers running Cumulus Linux 3.x which uses the BTRFS (b-tree file system) might experience issues with disk space management. This is a known problem of BTRFS because it does not perform periodic garbage collection, or rebalancing. If left unattended, these errors can make it impossible to rebalance the partitions on the disk. To avoid this issue, Cumulus Networks recommends rebalancing the BTRFS partitions in a preemptive manner, but only when absolutely needed to avoid reduction in the lifetime of the disk. By tracking the state of the disk space usage, users can determine when rebalancing should be performed.
Open the full-screen Switch card for a switch of interest:
Type the switch name in the Global Search box, then use the card size picker to open the full-screen card, or
Click (Switches), select Open a switch card, enter the switch name and select the full-screen card size.
Click BTRFS Utilization.
Look for the Rebalance Recommended column.
If the value in that column says Yes, then you are strongly encouraged to rebalance the BTRFS partitions. If it says No, then you can review the other values in the table to determine if you are getting close to needing a rebalance, and come back to view this table at a later time.
To view the disk utilization and whether a rebalance is recommended, run:
netq show cl-btrfs-util [around <text-time>] [json]
This example shows the utilization on the leaf01 switch:

Running NetQ on Linux hosts provides unprecedented network visibility, giving the network operator a complete view of the entire infrastructure’s network connectivity instead of just from the network devices.
The NetQ Agent is supported on the following Linux hosts:
Using NetQ on a Linux host is the same as using it on a Cumulus Linux switch. For example, if you want to check LLDP neighbor information about a given host, run:
With NetQ, a network administrator can monitor OSI Layer 1 physical
components on network devices, including interfaces, ports, links, and
peers. Keeping track of the various physical layer components in your switches
and servers ensures you have a fully functioning network and provides
inventory management and audit capabilities. You can monitor ports,
transceivers, and cabling deployed on a per port (interface), per
vendor, per part number and so forth. NetQ enables you to view the
current status and the status an earlier point in time. From this
information, you can, among other things:
Determine which ports are empty versus which ones have cables
plugged in and thereby validate expected connectivity
Audit transceiver and cable components used by vendor, giving you
insights for estimated replacement costs, repair costs, overall
costs, and so forth to improve your maintenance and purchasing
processes
Identify mismatched links
Identify changes in your physical layer, and when they occurred, indicating such items as bonds and links going down or flapping
NetQ uses LLDP (Link Layer Discovery Protocol) to collect port information. NetQ can also identify peer ports connected to DACs (Direct Attached Cables) and AOCs (Active Optical Cables) without using LLDP, even if the link is not UP.
View Component Information
You can view performance and status information about cables, transceiver modules, and interfaces using the netq show interfaces physical command. Its syntax is:
When entering a time value, you must include a numeric value and the unit of measure:
d: day(s)
w: week(s)
h: hour(s)
m: minute(s)
s: second(s)
now
For the between option, the start (text-time) and end time (text-endtime) values can be entered as most recent first and least recent second, or vice versa. The values do not have to have the same unit of measure.
View Detailed Cable Information for All Devices
You can view what cables are connected to each interface port for all devices, including the module type, vendor, part number and performance characteristics. You can also view the cable information for a given device by adding a hostname to the show command.

View Ports with Cables Connected for a Given Device
In a similar manner as checking for empty ports, you can check for ports that have cables connected, enabling you to compare expected versus actual deployment. You can also view the cable information for a given device by adding a hostname to the show command. If you add the around keyword, you can view which interface ports had cables connected at a previous time.
This example shows the ports of leaf01 switch that have attached cables.

View All Devices Using a Given Component
You can view all of the devices with ports using a particular component. This could be helpful when you need to change out a particular component for possible failure issues, upgrades, or cost reasons.
This example first determines which models (part numbers) exist on all of the devices
and then those devices with a part number of QSFP-H40G-CU1M installed.

View Changes to Physical Components
Because components are often changed, NetQ enables you to determine what, if any, changes have been made to the physical components on your devices. This can be helpful during deployments or upgrades.
You can select how far back in time you want to go, or select a time range using the between keyword. Note that time values must include units to be valid. If no changes are found, a “No matching cable records found” message is displayed.
This example illustrates each of these scenarios for all devices in the network.

View Utilization Statistics Networkwide
Utilization statistics provide a view into the operation of the devices in your network. They indicate whether resources are becoming dangerously close to their maximum capacity or a user-defined threshold. Depending on the function of the switch, the acceptable thresholds can vary.
View Compute Resources Utilization
You can quickly determine how many compute resources — CPU, disk and memory — are being consumed by the switches on your network.
To obtain this information, run the relevant command:
netq <hostname> show resource-util [cpu | memory] [around <text-time>] [json]
netq <hostname> show resource-util disk [<text-diskname>] [around <text-time>] [json]
When no options are included the output shows the percentage of CPU and memory being consumed as well as the amount and percentage of disk space being consumed. You can use the around option to view the information for a particular time.
This example shows the CPU, memory, and disk utilization for all devices.

View Port Statistics
The ethtool command provides a wealth of statistics about network interfaces. It returns statistics about a given node and interface, including frame errors, ACL drops, buffer drops and more. The syntax is:
netq [<hostname>] show ethtool-stats port <physical-port> (rx | tx) [extended] [around <text-time>] [json]
You can use the around option to view the information for a particular time. If no changes are found, a “No matching ethtool_stats records found” message is displayed.
This example shows the transmit statistics for switch port swp50 on a the leaf01 switch in the network.
NetQ Agents collect performance statistics every 30 seconds for the physical interfaces on switches in your network. The NetQ Agent does not collect statistics for non-physical interfaces, such as bonds, bridges, and VXLANs. The NetQ Agent collects the following statistics:
For NetQ Appliances that have 3ME3 solid state drives (SSDs) installed (primarily in on-premises deployments), you can view the utilization of the drive on-demand. An alarm is generated for drives that drop below 10% health, or have more than a two percent loss of health in 24 hours, indicating the need to rebalance the drive. Tracking SSD utilization over time enables you to see any downward trend or instability of the drive before you receive an alarm.
To view SDD utilization, run:
netq show cl-ssd-util [around <text-time>] [json]
This example shows the utilization for all devices which have this type of SSD.
cumulus@switch:~$ netq show cl-ssd-util

This output indicates that the one drive found of this type, on the spine02 switch, is in a good state overall with 80% of its PE cycles remaining. Use the around option to view this information around a particular time in the past.
View Disk Storage After BTRFS Allocation Networkwide
Customers running Cumulus Linux 3.x which uses the BTRFS (b-tree file system) might experience issues with disk space management. This is a known problem of BTRFS because it does not perform periodic garbage collection, or rebalancing. If left unattended, these errors can make it impossible to rebalance the partitions on the disk. To avoid this issue, Cumulus Networks recommends rebalancing the BTRFS partitions in a preemptive manner, but only when absolutely needed to avoid reduction in the lifetime of the disk. By tracking the state of the disk space usage, users can determine when rebalancing should be performed.
To view the disk utilization and whether a rebalance is recommended, run:
netq show cl-btrfs-util [around <text-time>] [json]
This example shows the utilization on all devices:
cumulus@switch:~$ netq show cl-btrfs-info
Matching btrfs_info records:

leaf01 37.79 % 3.58 GB 588.5 MB 771.91 MB yes Wed Sep 16 21:25:17 2020
Look for the Rebalance Recommended column. If the value in that column says Yes, then you are strongly encouraged to rebalance the BTRFS partitions. If it says No, then you can review the other values in the output to determine if you are getting close to needing a rebalance, and come back to view this data at a later time.
Optionally, use the around option to view the information for a particular time in the past.
Monitor Data Link Layer Protocols and Services
With NetQ, a user can monitor OSI Layer 2 devices and protocols, including switches, bridges, link control, and physical media access. Keeping track of the various data link layer devices in your network ensures consistent and error-free communications between devices.
It helps answer questions such as:
Is a VLAN misconfigured?
Is MLAG configured correctly?
Is LLDP running on all of my devices?
Is there an STP loop?
What is the status of interfaces on a device?
Where has a given MAC address lived in my network?
Monitor Interfaces
Interface (link) health can be monitored using the netq show interfaces command. You can view status of the links, whether they are operating over a VRF interface, the MTU of the link, and so forth. Using the hostname option enables you to view only the interfaces for a given device. View changes to interfaces using the netq show events command.
Viewing the status of all interfaces at once can be helpful when you are trying to compare configuration or status of a set of links, or generally when changes have been made.
This example shows all interfaces networkwide.
cumulus@switch:~$ netq show interfaces

View the Total Number of Interfaces
For a quick view of the amount of interfaces currently operating on a device, use the hostname and count options together.
This example shows the count of interfaces on the leaf03 switch.
cumulus@switch:~$ netq leaf03 show interfaces count
Count of matching link records: 28
View the Total Number of a Given Interface Type
It can be useful to see how many interfaces of a particular type you have on a device.
This example shows the count of swp interfaces are on the leaf03 switch.
cumulus@switch:~$ netq leaf03 show interfaces type swp count
Count of matching link records: 11
View Changes to Interfaces
If you suspect that an interface is not working as expected, seeing a drop in performance or a large number of dropped messages for example, you can view changes that have been made to interfaces networkwide.
This example shows info level events for all interfaces in your network.
cumulus@switch:~$ netq show events level info type interfaces between now and 30d

Check for MTU Inconsistencies
The maximum transmission unit (MTU) determines the largest size packet or frame that can be transmitted across a given communication link. When the MTU is not configured to the same value on both ends of the link, communication problems can occur. With NetQ, you can verify that the MTU is correctly specified for each link using the netq check mtu command.
This example shows that four switches have inconsistently specified link MTUs. Now the network administrator or operator can reconfigure the switches and eliminate the communication issues associated with this misconfiguration.
cumulus@switch:~$ netq check mtu
Checked Nodes: 15, Checked Links: 215, Failed Nodes: 4, Failed Links: 7

Monitor the LLDP Service
LLDP is used by network devices for advertising their identity, capabilities, and neighbors on a LAN. You can view this information for one or more devices. You can also view the information at an earlier point in time or view changes that have occurred to the information during a specified time period. For an overview and how to configure LLDP in your network, refer to Link Layer Discovery Protocol.
NetQ enables operators to view the overall health of the LLDP service on a networkwide and a per session basis, giving greater insight into all aspects of the service. This is accomplished in the NetQ UI through two card workflows, one for the service and one for the session and in the NetQ CLI with the netq show lldp command.
Monitor the LLDP Service Networkwide
With NetQ, you can monitor LLDP performance across the network:
Network Services|All LLDP Sessions
Small: view number of nodes running LLDP service and number of alarms
Medium: view number of nodes running LLDP service, number of sessions, and number of alarms
Large: view number of nodes running LLDP service, number of sessions and alarms, number of sessions without neighbors, switches with the most established/unestablished sessions
Full-screen: view all switches, all sessions, and all alarms
netq show lldp command: view associated host interface, peer hostname and interface, and last time a change was made for each session running LLDP
When entering a time value in the netq show lldp command, you must include a numeric value and the unit of measure:
w: week(s)
d: day(s)
h: hour(s)
m: minute(s)
s: second(s)
now
When using the between option, the start time (text-time) and end time (text-endtime) values can be entered as most recent first and least recent second, or vice versa. The values do not have to have the same unit of measure.
View Service Status Summary
You can view a summary of the LLDP service from the NetQ UI or the NetQ CLI.
Open the small Network Services|All LLDP Sessions card. In this example, the number of devices running the LLDP service is 14 and no alarms are present.
To view LLDP service status, run netq show lldp.
This example shows the Cumulus reference topology, where LLDP runs on all border, firewall, leaf, and spine switches, all servers, and the out-of-band management server. You can view the host interface, peer hostname and interface, and last time a change was made for each session.

View the Distribution of Nodes, Alarms, and Sessions
It is useful to know the number of network nodes running the LLDP protocol over a period of time and how many sessions are established on a given node, as it gives you insight into the amount of traffic associated with and breadth of use of the protocol. Additionally, if there are a large number of alarms, it is worth investigating either the service or particular devices.
Nodes which have a large number of unestablished sessions might be misconfigured or experiencing communication issues. This is visible with the NetQ UI.
To view the distribution, open the medium Network Services|All LLDP Sessions card.
In this example, we see that 13 nodes are running the LLDP protocol, that there are 52 sessions established, and that no LLDP-related alarms have occurred in the last 24 hours. If there was a visual correlation between the alarms and sessions, you could dig a little deeper with the large Network Services|All LLDP Sessions card.
To view the number of switches running the LLDP service, run:
netq show lldp
Count the switches in the output.
This example shows two border, two firewall, four leaf switches, four spine, and one out-of-band management switches, plus eight host servers are all running the LLDP service, for a total of 23 devices.

View the Distribution of Missing Neighbors
You can view the number of missing neighbors in any given time period and how that number has changed over time. This is a good indicator of link communication issues.
To view the distribution, open the large Network Services|ALL LLDP Sessions card and view the bottom chart on the left, Total Sessions with No Nbr.
In this example, we see that 16 of the 52 sessions are consistently missing the neighbor (peer) device over the last 24 hours.
View Devices with the Most LLDP Sessions
You can view the load from LLDP on your switches using the large Network Services|All LLDP Sessions card or the NetQ CLI. This data enables you to see which switches are handling the most LLDP traffic currently, validate that is what is expected based on your network design, and compare that with data from an earlier time to look for any differences.
To view switches and hosts with the most LLDP sessions:
Open the large Network Services|All LLDP Sessions card.
Select Switches with Most Sessions from the filter above the table.
The table content is sorted by this characteristic, listing nodes running the most LLDP sessions at the top. Scroll down to view those with the fewest sessions.
To compare this data with the same data at a previous time:
Open another large LLDP Service card.
Move the new card next to the original card if needed.
Change the time period for the data on the new card by hovering over the card and clicking .
Select the time period that you want to compare with the current time. You can now see whether there are significant differences between this time period and the previous time period.
In this case, notice that their are fewer nodes running the protocol, but the total number of sessions running has nearly doubled. If the changes are unexpected, you can investigate further by looking at another timeframe, determining if more nodes are now running LLDP than previously, looking for changes in the topology, and so forth.
To determine the devices with the most sessions, run netq show lldp. Then count the sessions on each device.
In this example, border01-02 each have eight sessions, fw1-2 each have two sessions, leaf01-04 each have 10 sessions, spine01-04 switches each have four sessions, server01-06 each have three sessions, and server07-08 and oob-mgmt-server each have one session. Therefore the leaf switches have the most sessions.

View Devices with the Most Unestablished LLDP Sessions
You can identify switches and hosts that are experiencing difficulties establishing LLDP sessions; both currently and in the past, using the NetQ UI.
To view switches with the most unestablished LLDP sessions:
Open the large Network Services|All LLDP Sessions card.
Select Switches with Most Unestablished Sessions from the filter above the table.
The table content is sorted by this characteristic, listing nodes with the most unestablished LLDP sessions at the top. Scroll down to view those with the fewest unestablished sessions.
Where to go next depends on what data you see, but a few options include:
Change the time period for the data to compare with a prior time. If the same switches are consistently indicating the most unestablished sessions, you might want to look more carefully at those switches using the Switches card workflow to determine probable causes. Refer to Monitor Switch Performance.
Click Show All Sessions to investigate all LLDP sessions with events in the full screen card.
View LLDP Configuration Information for a Given Device
You can view the LLDP configuration information for a given device from the NetQ UI or the NetQ CLI.
Open the full-screen Network Services|All LLDP Sessions card.
Click to filter by hostname.
Click Apply.
Run the netq show lldp command with the hostname option.
This example shows the LLDP configuration information for the leaf01 switch. The switch has a session between its swp1 interface and host server01 in the mac:44:38:39:00:00:32 interface. It also has a session between its swp2 interface and host server02 on mac:44:38:39:00:00:34 interface. And so on.

View Switches with the Most LLDP-related Alarms
Switches or hosts experiencing a large number of LLDP alarms may indicate a configuration or performance issue that needs further investigation. You can view this information using the NetQ UI or NetQ CLI.
With the NetQ UI, you can view the switches sorted by the number of LLDP alarms and then use the Switches card workflow or the Events|Alarms card workflow to gather more information about possible causes for the alarms.
To view switches with most LLDP alarms:
Open the large Network Services|All LLDP Sessions card.
Hover over the header and click .
Select Events by Most Active Device from the filter above the table.
The table content is sorted by this characteristic, listing nodes with the most LLDP alarms at the top. Scroll down to view those with the fewest alarms.
Where to go next depends on what data you see, but a few options include:
Change the time period for the data to compare with a prior time. If the same switches are consistently indicating the most alarms, you might want to look more carefully at those switches using the Switches card workflow.
Click Show All Sessions to investigate all switches running LLDP sessions in the full-screen card.
To view the switches and hosts with the most LLDP alarms and informational events, run the netq show events command with the type option set to lldp, and optionally the between option set to display the events within a given time range. Count the events associated with each switch.
This example shows that no LLDP events have occurred in the last 24 hours.

Monitor a Single LLDP Session
With NetQ, you can monitor the number of nodes running the LLDP service, view neighbor state changes, and compare with events occurring at the same time, as well as monitor the running LLDP configuration and changes to the configuration file. For an overview and how to configure LLDP in your data center network, refer to Link Layer Discovery Protocol.
To access the single session cards, you must open the full-screen Network Services|All LLDP Sessions card, click the All Sessions tab, select the desired session, then click (Open Card).
Granularity of Data Shown Based on Time Period
On the medium and large single LLDP session cards, the status of the neighboring peers is represented in heat maps stacked vertically; one for peers that are reachable (neighbor detected), and one for peers that are unreachable (neighbor not detected). Depending on the time period of data on the card, the number of smaller time blocks used to indicate the status varies. A vertical stack of time blocks, one from each map, includes the results from all checks during that time. The results are shown by how saturated the color is for each block. If all peers during that time period were detected for the entire time block, then the top block is 100% saturated (white) and the neighbor not detected block is zero percent saturated (gray). As peers become reachable, the neighbor detected block increases in saturation, the peers that are unreachable (neighbor not detected) block is proportionally reduced in saturation. An example heat map for a time period of 24 hours is shown here with the most common time periods in the table showing the resulting time blocks.

View Session Status Summary
You can view information about a given LLDP session using the NetQ UI or NetQ CLI.
A summary of the LLDP session is available from the Network Services|LLDP Session card workflow, showing the node and its peer and current status.
To view the summary:
Open the or add the Network Services|All LLDP Sessions card.
Change to the full-screen card using the card size picker.
Click the All Sessions tab.
Select the session of interest, then click (Open Card).
Locate the medium Network Services|LLDP Session card.
Optionally, open the small Network Services|LLDP Session card to keep track of the session health.
Run the netq show lldp command with the hostname and remote-physical-interface options.
This example show the session information for the leaf02 switch on swp49 interface of the leaf01 peer.
You can view the neighbor state for a given LLDP session from the medium and large LLDP Session cards. For a given time period, you can determine the stability of the LLDP session between two devices. If you experienced connectivity issues at a particular time, you can use these cards to help verify the state of the neighbor. If the neighbor was not alive more than it was alive, you can then investigate further into possible causes.
To view the neighbor availability for a given LLDP session on the medium card:
Open the or add the Network Services|All LLDP Sessions card.
Change to the full-screen card using the card size picker.
Click the All Sessions tab.
Select the session of interest, then click (Open Card).
Locate the medium Network Services|LLDP Session card.
In this example, the heat map tells us that this LLDP session has been able to detect a neighbor for the entire time period.
From this card, you can also view the host name and interface, and the peer name and interface.
To view the neighbor availability for a given LLDP session on the large LLDP Session card:
Open a Network Services|LLDP Session card.
Hover over the card, and change to the large card using the card size picker.
From this card, you can also view the alarm and info event counts, host interface name, peer hostname, and peer interface identifying the session in more detail.
View Changes to the LLDP Service Configuration File
Each time a change is made to the configuration file for the LLDP service, NetQ logs the change and enables you to compare it with the last version using the NetQ UI. This can be useful when you are troubleshooting potential causes for alarms or sessions losing their connections.
To view the configuration file changes:
Open or add the Network Services|All LLDP Sessions card.
Switch to the full-screen card using the card size picker.
Click the All Sessions tab.
Select the session of interest, then click (Open Card).
Locate the medium Network Services|LLDP Session card.
Hover over the card, and change to the large card using the card size picker.
Hover over the card and click to open the LLDP Configuration File Evolution tab.
Select the time of interest on the left; when a change may have impacted the performance. Scroll down if needed.
Choose between the File view and the Diff view (selected option is dark; File by default).
The File view displays the content of the file for you to review.
The Diff view displays the changes between this version (on left) and the most recent version (on right) side by side. The changes are highlighted in red and green. In this example, we don’t have any changes to the file, so the same file is shown on both sides, and thus no highlighted lines.
View All LLDP Session Details
You can view attributes of all of the LLDP sessions for the devices participating in a given session with the NetQ UI and the NetQ CLI.
To view all session details:
Open or add the Network Services|All LLDP Sessions card.
Switch to the full-screen card using the card size picker.
Click the All Sessions tab.
Select the session of interest, then click (Open Card).
Locate the medium Network Services|LLDP Session card.
Hover over the card, and change to the full-screen card using the card size picker. The All LLDP Sessions tab is displayed by default.
To return to your workbench, click in the top right of the card.
Run the netq show lldp command.
This example shows all LLDP sessions in the last 24 hours.

Monitor Spanning Tree Protocol
The Spanning Tree Protocol (STP) is used in Ethernet-based networks to prevent communication loops when you have redundant paths on a bridge or switch. Loops cause excessive broadcast messages greatly impacting the network performance.
With NetQ, you can view the STP topology on a bridge or switch to ensure no loops have been created using the netq show stp topology command. You can also view the topology information for a prior point in time to see if any changes were made around then.
The syntax for the show command is:
netq <hostname> show stp topology [around <text-time>] [json]
This example shows the STP topology as viewed from the spine1 switch.
If you do not have a bridge in your configuration, the output indicates such.
Monitor Virtual LANs
A VLAN (Virtual Local Area Network) enables devices on one or more LANs to communicate as if they were on the same network, without being physically connected. The VLAN enables network administrators to partition a network for functional or security requirements without changing physical infrastructure. For an overview and how to configure VLANs in your network, refer to Ethernet Bridging - VLANs.
With the NetQ CLI, you can view the operation of VLANs for one or all devices. You can also view the information at an earlier point in time or view changes that have occurred to the information during a specified timeframe. NetQ enables you to view basic VLAN information for your devices using the netq show vlan command. Additional show commands provide information about VLAN interfaces, MAC addresses associated with VLANs, and events.
The syntax for these commands is:
netq [<hostname>] show vlan [<1-4096>] [around <text-time>] [json]
netq show interfaces type vlan [state <remote-interface-state>] [around <text-time>] [json]
netq <hostname> show interfaces type vlan [state <remote-interface-state>] [around <text-time>] [count] [json]
netq show macs [<mac>] [vlan <1-4096>] [origin] [around <text-time>] [json]
netq <hostname> show macs [<mac>] [vlan <1-4096>] [origin | count] [around <text-time>] [json]
netq <hostname> show macs egress-port <egress-port> [<mac>] [vlan <1-4096>] [origin] [around <text-time>] [json]
netq [<hostname>] show events [level info | level error | level warning | level critical | level debug] type vlan [between <text-time> and <text-endtime>] [json]
When entering a time value, you must include a numeric value and the unit of measure:
w: week(s)
d: day(s)
h: hour(s)
m: minute(s)
s: second(s)
now
When using the between option, the start time (text-time) and end time (text-endtime) values can be entered as most recent first and least recent second, or vice versa. The values do not have to have the same unit of measure.
View VLAN Information for All Devices
You can view the configuration information for all VLANs in your network by running the netq show vlan command. It lists VLANs by device, and indicates any switch virtual interfaces (SVIs) configured and the last time this configuration was changed.
This example shows the VLANs configured across a network based on the Cumulus Networks reference architecture.

View the Number of VLAN Interfaces Configured
You can view the number of VLAN interfaces configured for a given device using the netq show vlan command with the hostname and count options.
This example shows the count of VLAN interfaces on the leaf02 switch in the last 24 hours.
cumulus@switch:~$ netq leaf02 show interfaces type vlan count
Count of matching link records: 6
View MAC Addresses Associated with a VLAN
You can determine the MAC addresses associated with a given VLAN using
the netq show macs vlan command. The command also provides the
hostnames of the devices, the egress port for the interface, whether the
MAC address originated from the given device, whether it learns the MAC
address from the peer (remote=yes), and the last time the configuration
was changed.
This example shows the MAC addresses associated with VLAN 10.
cumulus@switch:~$ netq show macs vlan 10

Monitor MAC Addresses
A MAC (media access control) address is a layer 2 construct that uses 48 bits to uniquely identify a network interface controller (NIC) for communication within a network.
With NetQ, you can:
View MAC address across the network and for a given device, VLAN, egress port on a VLAN, and VRR
View a count of MAC addresses on a given device
View where MAC addresses have lived in the network (MAC history)
View commentary on changes to MAC addresses (MAC commentary)
View events related to MAC addresses
The NetQ UI provides a listing of current MAC Addresses that can be filtered by hostname, timestamp, MAC address, VLAN, and origin. The list can be sorted by these parameters and also remote, static, and next hop.
The NetQ CLI provides the following commands:
netq show macs [<mac>] [vlan <1-4096>] [origin] [around <text-time>] [json]
netq <hostname> show macs [<mac>] [vlan <1-4096>] [origin | count] [around <text-time>] [json]
netq <hostname> show macs egress-port <egress-port> [<mac>] [vlan <1-4096>] [origin] [around <text-time>] [json]
netq [<hostname>] show mac-history <mac> [vlan <1-4096>] [diff] [between <text-time> and <text-endtime>] [listby <text-list-by>] [json]
netq [<hostname>] show mac-commentary <mac> vlan <1-4096> [between <text-time> and <text-endtime>] [json]
netq [<hostname>] show events [level info | level error | level warning | level critical | level debug] type macs [between <text-time> and <text-endtime>] [json]
When entering a time value, you must include a numeric value and the unit of measure:
w: week(s)
d: day(s)
h: hour(s)
m: minute(s)
s: second(s)
now
When using the between option, the start time (text-time) and end time (text-endtime) values can be entered as most recent first and least recent second, or vice versa. The values do not have to have the same unit of measure.
View MAC Addresses Networkwide
You can view all MAC addresses across your network with the NetQ UI or the NetQ CLI.
Use the netq show macs command to view all MAC addresses.
This example shows all MAC addresses in the Cumulus Networks reference topology.
cumulus@switch:~$ netq show macs

View MAC Addresses Associated with an Egress Port
You can the MAC addresses that use a particular egress port with the NetQ UI and the NetQ CLI.
Click (main menu).
Click MACs under the Network heading.
Toggle between A-Z or Z-A order of the egress port used by a MAC address by clicking the Egress Port header.
This example shows the MAC addresses sorted in A-Z order.
Optionally, click and enter a hostname to view the MAC addresses on a particular device.
This filters the list down to only the MAC addresses for a given device. Then, toggle between A-Z or Z-A order of the egress port used by a MAC address by clicking the Egress Port header.
Use the netq <hostname> show macs egress-port <egress-port> command to view the MAC addresses on a given device that use a given egress port. Note that you cannot view this information across all devices.
This example shows MAC addresses associated with the leaf03 switch that use the bridge port for egress.
cumulus@switch:~$ netq leaf03 show macs egress-port bridge

View the History of a MAC Address
It is useful when debugging to be able to see when a MAC address is learned, when and where it moved in the network after that, if there was a duplicate at any time, and so forth. The netq show mac-history command makes this information available. It enables you to see:
each change that was made chronologically
changes made between two points in time, using the between option
only the differences in the changes between two points in time using the diff option
the output ordered by selected output fields using the listby option
each change that was made for the MAC address on a particular VLAN, using the vlan option
The default time range used is now to one hour ago. You can view the output in JSON format as well.
View MAC Address Changes in Chronological Order
View the full listing of changes for a MAC address for the last hour in chronological order using the netq show mac-history command.
This example shows how to view a full chronology of changes for a MAC address of 44:38:39:00:00:5d. When shown, the caret (^) notation indicates no change in this value from the row above.

Monitor the MLAG Service
Multi-Chassis Link Aggregation (MLAG) is used to enable a server or switch with a two-port bond (such as a link aggregation group/LAG, EtherChannel, port group or trunk) to connect those ports to different switches and operate as if they are connected to a single, logical switch. This provides greater redundancy and greater system throughput. Dual-connected devices can create LACP bonds that contain links to each physical switch. Therefore, active-active links from the dual-connected devices are supported even though they are connected to two different physical switches. For an overview and how to configure MLAG in your network, refer to Multi-Chassis Link Aggregation - MLAG.
MLAG or CLAG?
The Cumulus Linux implementation of MLAG is referred to by other vendors as MLAG, MC-LAG or VPC. The Cumulus NetQ UI uses the MLAG terminology predominantly. However, the management daemon, named clagd, and other options in the code, such as clag-id, remain for historical purposes.
NetQ enables operators to view the health of the MLAG service on a networkwide and a per session basis, giving greater insight into all aspects of the service. This is accomplished in the NetQ UI through two card workflows, one for the service and one for the session and in the NetQ CLI with the netq show mlag command.
If you have prior scripts or automation that use the older netq show clag command, they will still work as the command has not been removed yet.
Monitor the MLAG Service Networkwide
With NetQ, you can monitor MLAG performance across the network:
Network Services|All MLAG Sessions
Small: view number of nodes running MLAG service and number and distribution of alarms
Medium: view number of nodes running MLAG service, number and distribution of sessions and alarms, number of sessions with inactive backup IPs, and number of bonds with single connections
Large: view number of nodes running MLAG service, number of sessions and alarms, number of sessions with inactive backup IPs, switches with the most established/unestablished sessions, devices with the most alarms
Full-screen: view all switches, all sessions, and all alarms
netq show mlag command: view host, peer, system MAC address, state, information about the bonds, and last time a change was made for each session running MLAG
When entering a time value in the netq show mlag command, you must include a numeric value and the unit of measure:
w: week(s)
d: day(s)
h: hour(s)
m: minute(s)
s: second(s)
now
When using the between option, the start time (text-time) and end time (text-endtime) values can be entered as most recent first and least recent second, or vice versa. The values do not have to have the same unit of measure.
View Service Status Summary
You can view a summary of the MLAG service from the NetQ UI or the NetQ CLI.
To view the summary, open the small Network Services|All MLAG Sessions card. In this example, the number of devices running the MLAG service is 4 and no alarms are present.
To view MLAG service status, run netq show mlag.
This example shows the Cumulus reference topology, where MLAG is configured on the border and leaf switches. You can view host, peer, system MAC address, state, information about the bonds, and last time a change was made for each MLAG session.
cumulus@switch~$ netq show mlag

View the Distribution of Sessions and Alarms
It is useful to know the number of network nodes running the MLAG protocol over a period of time, as it gives you insight into the amount of traffic associated with and breadth of use of the protocol. It is also useful to compare the number of nodes running MLAG with the alarms present at the same time to determine if there is any correlation between the issues and the ability to establish an MLAG session.
Nodes which have a large number of unestablished sessions might be misconfigured or experiencing communication issues. This is visible with the NetQ UI.
To view the distribution, open the medium Network Services|All MLAG Sessions card.
This example shows the following for the last 24 hours:
Four nodes have been running the MLAG protocol with no changes in that number
Four sessions were established and remained so
No MLAG-related alarms have occurred
If there was a visual correlation between the alarms and sessions, you could dig a little deeper with the large Network Services|All MLAG Sessions card.
To view the number of switches running the MLAG service, run:
netq show mlag
Count the switches in the output.
This example shows two border and four leaf switches, for a total of six switches running the protocol. The device in each session acting in the primary role is marked with (P).

View Bonds with Only a Single Link
You can determine whether there are any bonds in your MLAG configuration with only a single link, instead of the usual two, using the NetQ UI or the NetQ CLI.
Open the medium Network Services|All MLAG Sessions card.
This example shows that four bonds have single links.
Hover over the card and change to the full-screen card using the card size picker.
Click the All Sessions tab.
Browse the sessions looking for either a blank value in the Dual Bonds column, or with one or more bonds listed in the Single Bonds column, to determine whether or not the devices participating in these sessions are incorrectly configured.
Optionally, change the time period of the data on either size card to determine when the configuration may have changed from a dual to a single bond.
Run the netq show mlag command to view bonds with single links in the last 24 hours. Use the around option to view bonds with single links for a time in the past.
This example shows that no bonds have single links, because the #Bonds value equals the #Dual value for all sessions.

View Sessions with Conflicted Bonds
You can view sessions with conflicted bonds (bonds that conflict with existing bond relationships) in the NetQ UI.
To view these sessions:
Open the Network Services|All MLAG Sessions card.
Hover over the card and change to the full-screen card using the card size picker.
Click the All Sessions tab.
Scroll to the right to view the Conflicted Bonds column. Based on the value/s in that field, reconfigure MLAG accordingly, using the net add bond NCLU command or edit the /etc/network/interfaces file. Refer to Basic Configuration in the Cumulus Linux MLAG topic.
View Devices with the Most MLAG Sessions
You can view the load from MLAG on your switches using the large Network Services|All MLAG Sessions card. This data enables you to see which switches are handling the most MLAG traffic currently, validate that is what is expected based on your network design, and compare that with data from an earlier time to look for any differences.
To view switches and hosts with the most MLAG sessions:
Open the large Network Services|All MLAG Sessions card.
Select Switches with Most Sessions from the filter above the table.
The table content is sorted by this characteristic, listing nodes running the most MLAG sessions at the top. Scroll down to view those with the fewest sessions.
To compare this data with the same data at a previous time:
Open another large Network Services|All MLAG Sessions card.
Move the new card next to the original card if needed.
Change the time period for the data on the new card by hovering over the card and clicking .
Select the time period that you want to compare with the current time. You can now see whether there are significant differences between this time period and the previous time period.
If the changes are unexpected, you can investigate further by looking at another timeframe, determining if more nodes are now running MLAG than previously, looking for changes in the topology, and so forth.
To determine the devices with the most sessions, run netq show mlag. Then count the sessions on each device.
In this example, there are two sessions between border01 and border02, two sessions between leaf01 and leaf02, and two session between leaf03 and leaf04. Therefore, no devices has more sessions that any other.

With NetQ, you can monitor the number of nodes running the MLAG service, view switches with the most peers alive and not alive, and view alarms triggered by the MLAG service. For an overview and how to configure MLAG in your data center network, refer to Multi-Chassis Link Aggregation - MLAG.
To access the single session cards, you must open the full-screen Network Services|All MLAG Sessions card, click the All Sessions tab, select the desired session, then click (Open Card).
Granularity of Data Shown Based on Time Period
On the medium and large single MLAG session cards, the status of the peers is represented in heat maps stacked vertically; one for peers that are reachable (alive), and one for peers that are unreachable (not alive). Depending on the time period of data on the card, the number of smaller time blocks used to indicate the status varies. A vertical stack of time blocks, one from each map, includes the results from all checks during that time. The results are shown by how saturated the color is for each block. If all peers during that time period were alive for the entire time block, then the top block is 100% saturated (white) and the not alive block is zero percent saturated (gray). As peers that are not alive increase in saturation, the peers that are alive block is proportionally reduced in saturation. An example heat map for a time period of 24 hours is shown here with the most common time periods in the table showing the resulting time blocks.

View Session Status Summary
A summary of the MLAG session is available about a given MLAG session using the NetQ UI or NetQ CLI.
A summary of the MLAG session is available from the Network Services|MLAG Session card workflow, showing the host and peer devices participating in the session, node role, peer role and state, the associated system MAC address, and the distribution of the MLAG session state.
To view the summary:
Open or add the Network Services|All MLAG Sessions card.
Change to the full-screen card using the card size picker.
Click the All Sessions tab.
Select the session of interest, then click (Open Card).
Locate the medium Network Services|MLAG Session card.
In the left example, we see that the tor1 switch plays the secondary role in this session with the switch at 44:38:39:ff:01:01 and that there is an issue with this session. In the right example, we see that the leaf03 switch plays the primary role in this session with leaf04 and this session is in good health.
Optionally, open the small Network Services|MLAG Session card to keep track of the session health.
Run the netq show mlag command with the hostname option.
This example shows the session information when the leaf01 switch is acting as the primary role in the session.
cumulus@switch:~$ netq leaf01 show mlag

View MLAG Session Peering State Changes
You can view the peering state for a given MLAG session from the medium and large MLAG Session cards. For a given time period, you can determine the stability of the MLAG session between two devices. If you experienced connectivity issues at a particular time, you can use these cards to help verify the state of the peer. If the peer was not alive more than it was alive, you can then investigate further into possible causes.
To view the state transitions for a given MLAG session on the medium card:
Open the or add the Network Services|All MLAG Sessions card.
Change to the full-screen card using the card size picker.
Click the All Sessions tab.
Select the session of interest, then click (Open Card).
Locate the medium Network Services|MLAG Session card.
In this example, the heat map tells us that the peer switch has been alive for the entire 24-hour period.
From this card, you can also view the node role, peer role and state, and MLAG system MAC address which identify the session in more detail.
To view the peering state transitions for a given MLAG session on the large Network Services|MLAG Session card:
Open a Network Services|MLAG Session card.
Hover over the card, and change to the large card using the card size picker.
From this card, you can also view the alarm and info event counts, node role, peer role, state, and interface, MLAG system MAC address, active backup IP address, single, dual, conflicted, and protocol down bonds, and the VXLAN anycast address identifying the session in more detail.
View Changes to the MLAG Service Configuration File
Each time a change is made to the configuration file for the MLAG service, NetQ logs the change and enables you to compare it with the last version using the NetQ UI. This can be useful when you are troubleshooting potential causes for alarms or sessions losing their connections.
To view the configuration file changes:
Open or add the Network Services|All MLAG Sessions card.
Switch to the full-screen card using the card size picker.
Click the All Sessions tab.
Select the session of interest, then click (Open Card).
Locate the medium Network Services|MLAG Session card.
Hover over the card, and change to the large card using the card size picker.
Hover over the card and click to open the Configuration File Evolution tab.
Select the time of interest on the left; when a change may have impacted the performance. Scroll down if needed.
Choose between the File view and the Diff view (selected option is dark; File by default).
The File view displays the content of the file for you to review.
The Diff view displays the changes between this version (on left) and the most recent version (on right) side by side. The changes are highlighted in red and green. In this example, we don’t have any changes after this first creation, so the same file is shown on both sides and no highlighting is present.
All MLAG Session Details
You can view attributes of all of the MLAG sessions for the devices participating in a given session with the NetQ UI and the NetQ CLI.
To view all session details:
Open or add the Network Services|All MLAG Sessions card.
Switch to the full-screen card using the card size picker.
Click the All Sessions tab.
Select the session of interest, then click (Open Card).
Locate the medium Network Services|MLAG Session card.
Hover over the card, and change to the full-screen card using the card size picker. The All MLAG Sessions tab is displayed by default.
Where to go next depends on what data you see, but a few options include:
Open the All Events tabs to look more closely at the alarm and info events fin the network.
Sort on other parameters:
By Single Bonds to determine which interface sets are only connected to one of the switches.
By Backup IP and Backup IP Active to determine if the correct backup IP address is specified for the service.
Export the data to a file by clicking .
Return to your workbench by clicking in the top right corner.
Run the netq show mlag command.
This example shows all MLAG sessions in the last 24 hours.
cumulus@switch:~$ netq show mlag

Monitor Network Layer Protocols and Services
The core capabilities of Cumulus NetQ enable you to monitor your network by viewing performance and configuration data about your individual network devices and the entire fabric networkwide. The topics contained in this section describe monitoring tasks that apply across the entire network. For device-specific monitoring refer to Monitor Devices.
Monitor Internet Protocol Service
With NetQ, a user can monitor IP (Internet Protocol) addresses, neighbors, and routes, including viewing the current status and the status an earlier point in time.
It helps answer questions such as:
Who are the IP neighbors for each switch?
How many IPv4 and IPv6 addresses am I using in total and on which interface?
Which routes are owned by which switches?
When did changes occur to my IP configuration?
The netq show ip command is used to obtain the address, neighbor, and
route information from the devices. Its syntax is:
netq <hostname> show ip addresses [<remote-interface>] [<ipv4>|<ipv4/prefixlen>] [vrf <vrf>] [around <text-time>] [count] [json]
netq [<hostname>] show ip addresses [<remote-interface>] [<ipv4>|<ipv4/prefixlen>] [vrf <vrf>] [around <text-time>] [json]
netq show ip addresses [<remote-interface>] [<ipv4>|<ipv4/prefixlen>] [vrf <vrf>] [subnet|supernet|gateway] [around <text-time>] [json]
netq <hostname> show ip neighbors [<remote-interface>] [<ipv4>|<ipv4> vrf <vrf>|vrf <vrf>] [<mac>] [around <text-time>] [json]
netq [<hostname>] show ip neighbors [<remote-interface>] [<ipv4>|<ipv4> vrf <vrf>|vrf <vrf>] [<mac>] [around <text-time>] [count] [json]
netq <hostname> show ip routes [<ipv4>|<ipv4/prefixlen>] [vrf <vrf>] [origin] [around <text-time>] [count] [json]
netq [<hostname>] show ip routes [<ipv4>|<ipv4/prefixlen>] [vrf <vrf>] [origin] [around <text-time>] [json]
netq <hostname> show ipv6 addresses [<remote-interface>] [<ipv6>|<ipv6/prefixlen>] [vrf <vrf>] [around <text-time>] [count] [json]
netq [<hostname>] show ipv6 addresses [<remote-interface>] [<ipv6>|<ipv6/prefixlen>] [vrf <vrf>] [around <text-time>] [json]
netq show ipv6 addresses [<remote-interface>] [<ipv6>|<ipv6/prefixlen>] [vrf <vrf>] [subnet|supernet|gateway] [around <text-time>] [json]
netq <hostname> show ipv6 neighbors [<remote-interface>] [<ipv6>|<ipv6> vrf <vrf>|vrf <vrf>] [<mac>] [around <text-time>] [count] [json]
netq [<hostname>] show ipv6 neighbors [<remote-interface>] [<ipv6>|<ipv6> vrf <vrf>|vrf <vrf>] [<mac>] [around <text-time>] [json]
netq <hostname> show ipv6 routes [<ipv6>|<ipv6/prefixlen>] [vrf <vrf>] [origin] [around <text-time>] [count] [json]
netq [<hostname>] show ipv6 routes [<ipv6>|<ipv6/prefixlen>] [vrf <vrf>] [origin] [around <text-time>] [json]
When entering a time value, you must include a numeric value and the unit of measure:
w: week(s)
d: day(s)
h: hour(s)
m: minute(s)
s: second(s)
now
For the between option, the start (text-time) and end time (text-endtime) values can be entered as most recent first and least recent second, or vice versa. The values do not have to have the same unit of measure.
View IP Address Information
You can view the IPv4 and IPv6 address information for all of your devices, including the interface and VRF for each device. Additionally, you can:
View the information at an earlier point in time
Filter against a particular device, interface or VRF assignment
Obtain a count of all of the addresses
Each of these provides information for troubleshooting potential configuration and communication issues at the layer 3 level.
View IPv4 Address Information for All Devices
To view only IPv4 addresses, run netq show ip addresses. This example shows all IPv4 addresses in the reference topology.
cumulus@switch:~$ netq show ip addresses

Obtain a Count of IP Addresses Used on a Device
If you are concerned that a particular device an overload of addresses in use, you can quickly view the address count using the count option.
This example shows the number of IPv4 and IPv6 addresses on the leaf01 switch.
cumulus@switch:~$ netq leaf01 show ip addresses count
Count of matching address records: 9
cumulus@switch:~$ netq leaf01 show ipv6 addresses count
Count of matching address records: 17
View IP Neighbor Information
You can view the IPv4 and IPv6 neighbor information for all of your devices, including the interface port, MAC address, VRF assignment, and whether it learns the MAC address from the peer (remote=yes).
Additionally, you can:
View the information at an earlier point in time
Filter against a particular device, interface, address or VRF assignment
Obtain a count of all of the addresses
Each of these provides information for troubleshooting potential configuration and communication issues at the layer 3 level.
View IP Neighbor Information for All Devices
You can view neighbor information for all devices running IPv4 or IPv6 using the netq show ip/ipv6 neighbors command.
This example shows all neighbors for devices running IPv4.
cumulus@switch:~$ netq show ip neighbors

View IP Routes Information
You can view the IPv4 and IPv6 routes for all of your devices, including the IP address (with or without mask), the destination (by hostname) of the route, next hops available, VRF assignment, and whether a host is the owner of the route or MAC address. Additionally, you can:
View the information at an earlier point in time
Filter against a particular address or VRF assignment
Obtain a count of all of the routes
Each of these provides information for troubleshooting potential configuration and communication issues at the layer 3 level.

View the History of an IP Address
It is useful when debugging to be able to see when the IP address configuration changed for an interface. The netq show address-history command makes this information available. It enables you to see:
each change that was made chronologically
changes made between two points in time, using the between option
only the difference between to points in time using the diff option
to order the output by selected output fields using the listby option
each change that was made for the IP address on a particular interface, using the ifname option
And as with many NetQ commands, the default time range used is now to one hour ago. You can view the output in JSON format as well.
The syntax of the command is:
netq [<hostname>] show address-history <text-prefix> [ifname <text-ifname>] [vrf <text-vrf>] [diff] [between <text-time> and <text-endtime>] [listby <text-list-by>] [json]
When entering a time value, you must include a numeric value and the unit of measure:
w: week(s)
d: day(s)
h: hour(s)
m: minute(s)
s: second(s)
now
For the between option, the start (text-time) and end time (text-endtime) values can be entered as most recent first and least recent second, or vice versa. The values do not have to have the same unit of measure.
This example shows how to view a full chronology of changes for an IP address. If a caret (^) notation appeared, it would indicate that there was no change in this value from the row above.

Monitor the BGP Service
BGP is the routing protocol that runs the Internet. It is an increasingly popular protocol for use in the data center as it lends itself well to the rich interconnections in a Clos topology. Specifically, BGP:
Does not require the routing state to be periodically refreshed, unlike OSPF.
Is less chatty than its link-state siblings. For example, a link or node transition can result in a bestpath change, causing BGP to send updates.
Is multi-protocol and extensible.
Has many robust vendor implementations.
Is very mature as a protocol and comes with many years of operational experience.
RFC 7938 provides further details of the use of BGP within the data center. For an overview and how to configure BGP to run in your data center network, refer to Border Gateway Protocol - BGP.
NetQ enables operators to view the health of the BGP service on a networkwide or per session basis, giving greater insight into all aspects of the service. This is accomplished in the NetQ UI through two card workflows, one for the service and one for the session and in the NetQ CLI with the netq show bgp command.
Monitor the BGP Service Networkwide
With NetQ, you can monitor BGP performance across the network:
Network Services|All BGP Sessions
Small: view number of nodes running BGP service and distribution and number of alarms
Medium: view number and distribution of nodes running BGP service, alarms, and with unestablished sessions
Large: view number and distribution of nodes running BGP service and those with unestablished sessions, and view nodes with the most established and unestablished BGP sessions
Full-screen: view all switches, all sessions, and all alarms
netq show bgp command: view associated neighbors, ASN (autonomous system number), peer ASN, receive IP or EVPN address prefixes, and VRF assignment for each node
When entering a time value in the netq show bgp command, you must include a numeric value and the unit of measure:
w: week(s)
d: day(s)
h: hour(s)
m: minute(s)
s: second(s)
now
When using the between option, the start time (text-time) and end time (text-endtime) values can be entered as most recent first and least recent second, or vice versa. The values do not have to have the same unit of measure.
View Service Status Summary
You can view a summary of BGP service with the NetQ UI or the NetQ CLI.
To view the summary, open the small Network Services|All BGP Sessions card.
To view the summary, run netq show bgp.
This example shows each node, their neighbor, VRF, ASN, Peer ASN, Address Prefix, and last time this was changed.
It is useful to know the number of network nodes running the BGP protocol over a period of time, as it gives you insight into the amount of traffic associated with and breadth of use of the protocol.
It is also useful to compare the number of nodes running BGP with unestablished sessions with the alarms present at the same time to determine if there is any correlation between the issues and the ability to establish a BGP session. This is visible with the NetQ UI.
To view these distributions, open the medium Network Services|All BGP Sessions card.
In this example, we see that 10 nodes are running the BGP protocol, there are no nodes with unestablished sessions, and that 54 LLDP-related alarms have occurred in the last 24 hours. If a visual correlation between the alarms and unestablished sessions is apparent, you can dig a little deeper with the large Network Services|All BGP Sessions card.
To view the number of switches running the BGP service, run:
netq show bgp
Count the switches in the output.
This example shows two border switches, four leaf switches, and four spine switches are running the BGP service, for a total of 10.
You can view the load from BGP on your switches and hosts using the large Network Services|All BGP Sessions card or the NetQ CLI. This data enables you to see which switches are handling the most BGP sessions currently, validate that is what is expected based on your network design, and compare that with data from an earlier time to look for any differences.
To view switches and hosts with the most BGP sessions:
Open the large Network Services|ALL BGP Sessions card.
Select Switches With Most Sessions from the filter above the table.
The table content is sorted by this characteristic, listing nodes running the most BGP sessions at the top. Scroll down to view those with the fewest sessions.
To compare this data with the same data at a previous time:
Open another large BGP Service card.
Move the new card next to the original card if needed.
Change the time period for the data on the new card by hovering over the card and clicking .
Select the time period that you want to compare with the original time. We chose Past Week for this example.
You can now see whether there are significant differences between this time and the original time. If the changes are unexpected, you can investigate further by looking at another timeframe, determining if more nodes are now running BGP than previously, looking for changes in the topology, and so forth.
To determine the devices with the most sessions, run netq show bgp. Then count the sessions on each device.
In this example, border01-02 and leaf01-04 each have four sessions. The spine01-04 switches each have five sessions. Therefore the spine switches have the most sessions.
View Devices with the Most Unestablished BGP Sessions
You can identify switches and hosts that are experiencing difficulties establishing BGP sessions; both currently and in the past, using the NetQ UI.
To view switches with the most unestablished BGP sessions:
Open the large Network Services|All BGP Sessions card.
Select Switches with Most Unestablished Sessions from the filter above the table.
The table content is sorted by this characteristic, listing nodes with the most unestablished BGP sessions at the top. Scroll down to view those with the fewest unestablished sessions.
Where to go next depends on what data you see, but a couple of options
include:
Change the time period for the data to compare with a prior time.
If the same switches are consistently indicating the most unestablished sessions, you might want to look more carefully at those switches using the Switches card workflow to determine probable causes. Refer to Monitor Switch Performance.
Click Show All Sessions to investigate all BGP sessions with events in the full screen card.
View BGP Configuration Information for a Given Device
You can view the BGP configuration information for a given device from the NetQ UI or the NetQ CLI.
Open the full-screen Network Services|All BGP Sessions card.
Click to filter by hostname.
Click Apply.
Run the netq show bgp command with the hostname option.
This example shows the BGP configuration information for the spine02
switch. The switch is peered with swp1 on leaf01, swp2 on leaf02, and so
on. Spine02 has an ASN of 65199 and each of the peers have unique ASNs.
View BGP Configuration Information for a Given ASN
You can view the BGP configuration information for a given ASN from the NetQ UI or the NetQ CLI.
Open the full-screen Network Services|All BGP Sessions card.
Locate the ASN column.
You may want to pause the auto-refresh feature during this process to avoid the page update while you are browsing the data.
Click the header to sort on that column.
Scroll down as needed to find the devices using the ASN of interest.
Run the netq show bgp command with the asn <number-asn> option.
This example shows the BGP configuration information for ASN of
65102. This ASN is associated with leaf02-leaf04 and so the results show
the BGP neighbors for those switches.
Switches or hosts experiencing a large number of BGP alarms may indicate a configuration or performance issue that needs further investigation. You can view this information using the NetQ UI or NetQ CLI.
With the NetQ UI, you can view the devices sorted by the number of BGP alarms and then use the Switches card workflow or the Events|Alarms card workflow to gather more information about possible causes for the alarms.
To view switches with the most BGP alarms:
Open the large Network Services|All BGP Sessions card.
Hover over the header and click .
Select Switches with Most Alarms from the filter above the table.
The table content is sorted by this characteristic, listing nodes with the most BGP alarms at the top. Scroll down to view those with the fewest alarms.
Where to go next depends on what data you see, but a few options include:
Change the time period for the data to compare with a prior time. If the same switches are consistently indicating the most alarms, you might want to look more carefully at those switches using the Switches card workflow.
Click Show All Sessions to investigate all BGP sessions with events in the full-screen card.
To view the switches and hosts with the most BGP alarms and informational events, run the netq show events command with the type option set to bgp, and optionally the between option set to display the events within a given time range. Count the events associated with each switch.
This example shows all BGP events between now and five days ago.
cumulus@switch:~$ netq show events type bgp between now and 5d

View Details for All Devices Running BGP
You can view all stored attributes of all switches and hosts running BGP in your network in the full-screen Network Services|All BGP Sessions card in the NetQ UI.
To view all device details, open the full-screen Network Services|All BGP Sessions card and click the All Switches tab.
To return to your workbench, click in the top right corner.
View Details for All BGP Sessions
You can view attributes of all BGP sessions in your network with the NetQ UI or NetQ CLI.
To view all session details, open the full-screen Network Services|All BGP Sessions card and click the All Sessions tab.
Use the icons above the table to select/deselect, filter, and export items in the list. Refer to Table Settings for more detail.
To return to your workbench, click in the top right corner.
To view session details, run netq show bgp.
This example shows all current sessions (one per row) and the attributes associated with them.
With NetQ, you can monitor a single session of the BGP service, view session state changes, and compare with alarms occurring at the same time, as well as monitor the running BGP configuration and changes to the configuration file. For an overview and how to configure BGP to run in your data center network, refer to Border Gateway Protocol - BGP.
To access the single session cards, you must open the full-screen Network Services|All BGP Sessions card, click the All Sessions tab, select the desired session, then click (Open Card).
Granularity of Data Shown Based on Time Period
On the medium and large single BGP session cards, the status of the sessions is represented in heat maps stacked vertically; one for established sessions, and one for unestablished sessions. Depending on the time period of data on the card, the number of smaller time blocks used to indicate the status varies. A vertical stack of time blocks, one from each map, includes the results from all checks during that time. The results are shown by how saturated the color is for each block. If all sessions during that time period were established for the entire time block, then the top block is 100% saturated (white) and the not established block is zero percent saturated (gray). As sessions that are not established increase in saturation, the sessions that are established block is proportionally reduced in saturation. An example heat map for a time period of 24 hours is shown here with the most common time periods in the table showing the resulting time blocks.

View BGP Session State Changes
You can view the state of a given BGP session from the medium and large Network Service|All BGP Sessions card in the NetQ UI. For a given time period, you can determine the stability of the BGP session between two devices. If you experienced connectivity issues at a particular time, you can use these cards to help verify the state of the session. If it was not established more than it was established, you can then investigate further into possible causes.
To view the state transitions for a given BGP session, on the medium BGP Session card:
Open or add the Network Services|All BGP Sessions card.
Switch to the full-screen card using the card size picker.
Click the All Sessions tab.
Select the session of interest, then click (Open Card).

Monitor the OSPF Service
OSPF maintains the view of the network topology conceptually as a directed graph. Each router represents a vertex in the graph. Each link between neighboring routers represents a unidirectional edge and has an associated weight (called cost) that is either automatically derived from its bandwidth or administratively assigned. Using the weighted topology graph, each router computes a shortest path tree (SPT) with itself as the root, and applies the results to build its forwarding table. For more information about OSPF operation and how to configure OSPF to run in your data center network, refer to Open Shortest Path First - OSPF or Open Shortest Path First v3 - OSPFv3.
If you have OSPF running on your switches and hosts, NetQ enables you to view the health of the OSPF service on a networkwide and a per session basis, giving greater insight into all aspects of the service. For each device, you can view its associated interfaces, areas, peers, state, and type of OSPF running (numbered or unnumbered). Additionally, you can view the information at an earlier point in time and filter against a particular device, interface, or area.
This is accomplished in the NetQ UI through two card workflows, one for the service and one for the session, and in the NetQ CLI with the netq show ospf command.
Monitor the OSPF Service Networkwide
With NetQ, you can monitor OSPF performance across the network:
Network Services|All OSPF Sessions
Small: view number of nodes running OSPF service and number and distribution of alarms
Medium: view number and distribution of nodes running OSPF service, total sessions, unestablished sessions, and alarms
Large: view number and distribution of nodes running OSPF service, total sessions, unestablished sessions, and alarms, switches with the most established sessions/alarms
Full-screen: view and filter configuration and status for all switches, all sessions, and all alarms
netq show ospf command: view configuration and status for all devices, including interface, area, type, state, peer hostname and interface, and last time a change was made for each device
When entering a time value, you must include a numeric value and the unit of measure:
w: week(s)
d: day(s)
h: hour(s)
m: minute(s)
s: second(s)
now
For the between option, the start (text-time) and end time (text-endtime) values can be entered as most recent first and least recent second, or vice versa. The values do not have to have the same unit of measure.
View Service Status Summary
You can view a summary of the OSPF service from the NetQ UI or the NetQ CLI.
To view the summary, open the Network Services|All OSPF Sessions card. In this example, the number of devices running the OSPF service is nine (9) and the number and distribution of related critical severity alarms is zero (0).
To view OSPF service status, run:
netq show ospf
This example shows all devices included in OSPF unnumbered routing, the assigned areas, state, peer and interface, and the last time this information was changed.
cumulus@switch:~$ netq show ospf

View the Distribution of Sessions
It is useful to know the number of network nodes running the OSPF protocol over a period of time, as it gives you insight into the amount of traffic associated with and breadth of use of the protocol. It is also useful to view the health of the sessions.
To view these distributions, open the medium Network Services|All OSPF Sessions card. In this example, there are nine nodes running the service with a total of 40 sessions. This has not changed over the past 24 hours.
To view the number of switches running the OSPF service, run:
netq show ospf
Count the switches in the output.
This example shows four leaf switches and two spine switches are running the OSPF service, for a total of six switches.

To compare this count with the count at another time, run the netq show ospf command with the around option. Count the devices running OSPF at that time. Repeat with another time to collect a picture of changes over time.
View Devices with the Most OSPF Sessions
You can view the load from OSPF on your switches and hosts using the large Network Services card. This data enables you to see which switches are handling the most OSPF traffic currently, validate that is what is expected based on your network design, and compare that with data from an earlier time to look for any differences.
To view switches and hosts with the most OSPF sessions:
Open the large Network Services|All OSPF Sessions card.
Select Switches with Most Sessions from the filter above the table.
The table content is sorted by this characteristic, listing nodes running the most OSPF sessions at the top. Scroll down to view those with the fewest sessions.
To compare this data with the same data at a previous time:
Open another large OSPF Service card.
Move the new card next to the original card if needed.
Change the time period for the data on the new card by hovering over the card and clicking .
Select the time period that you want to compare with the original time. We chose Past Week for this example.
You can now see whether there are significant differences between this time and the original time. If the changes are unexpected, you can investigate further by looking at another timeframe, determining if more nodes are now running OSPF than previously, looking for changes in the topology, and so forth.
To determine the devices with the most sessions, run netq show ospf. Then count the sessions on each device.
In this example, the leaf01-04 switches each have two sessions and the spine01-02 switches have four session each. Therefore the spine switches have the most sessions.

Monitor a Single OSPF Session
With NetQ, you can monitor the performance of a single OSPF session using the NetQ UI or the NetQ CLI.
Network Services|OSPF Session
Small: view devices participating in the session and summary status
Medium: view devices participating in the session, summary status, session state changes, and key identifiers of the session
Large: view devices participating in the session, summary status, session state changes, event distribution and counts, attributes of the session, and the running OSPF configuration and changes to the configuration file
Full-screen: view all session attributes and all events
netq <hostname> show ospf command: view configuration and status for session by hostname, including interface, area, type, state, peer hostname, peer interface, and the last time this information changed
To access the single session cards, you must open the full screen Network Services|All OSPF Sessions card, click the All Sessions tab, select the desired session, then click (Open Card).
Granularity of Data Shown Based on Time Period
On the medium and large single OSPF session cards, the status of the sessions is represented in heat maps stacked vertically; one for established sessions, and one for unestablished sessions. Depending on the time period of data on the card, the number of smaller time blocks used to indicate the status varies. A vertical stack of time blocks, one from each map, includes the results from all checks during that time. The results are shown by how saturated the color is for each block. If all sessions during that time period were established for the entire time block, then the top block is 100% saturated (white) and the not established block is zero percent saturated (gray). As sessions that are not established increase in saturation, the sessions that are established block is proportionally reduced in saturation. An example heat map for a time period of 24 hours is shown here with the most common time periods in the table showing the resulting time blocks.

View OSPF Session State Changes
You can view the state of a given OSPF session from the medium and large Network Service|All OSPF Sessions card. For a given time period, you can determine the stability of the OSPF session between two devices. If you experienced connectivity issues at a particular time, you can use these cards to help verify the state of the session. If it was not established more than it was established, you can then investigate further into possible causes.
To view the state transitions for a given OSPF session, on the medium OSPF Session card:
Open the Network Services|All OSPF Sessions card.
Switch to the full-screen card using the card size picker.
Click the All Sessions tab.
Select the session of interest. The full-screen card closes automatically.
The heat map indicates the status of the session over the designated time period. In this example, the session has been established for the entire time period.
From this card, you can also view the interface name, peer address, and peer id identifying the session in more detail.
To view the state transitions for a given OSPF session on the large OSPF Session card:
Open a Network Services|OSPF Session card.
Hover over the card, and change to the large card using the card size picker.
From this card, you can view the alarm and info event counts, interface name, peer address and peer id, state, and several other parameters identifying the session in more detail.
View Changes to the OSPF Service Configuration File
Each time a change is made to the configuration file for the OSPF service, NetQ logs the change and enables you to compare it with the last version using the NetQ UI. This can be useful when you are troubleshooting potential causes for alarms or sessions losing their connections.
To view the configuration file changes:
Open or add the Network Services|All OSPF Sessions card.
Switch to the full-screen card.
Click the All Sessions tab.
Select the session of interest. The full-screen card closes automatically.
Hover over the card, and change to the large card using the card size picker.

Monitor Virtual Network Overlays
Cumulus Linux supports network virtualization with EVPN and VXLANs. For more detail about what and how network virtualization is supported, refer to the Cumulus Linux topic. For information about monitoring EVPN and VXLANs with NetQ, continue with the topics here.
Monitor the EVPN Service
EVPN (Ethernet Virtual Private Network) enables network administrators in the data center to deploy a virtual layer 2 bridge overlay on top of layer 3 IP networks creating access, or tunnel, between two locations. This connects devices in different layer 2 domains or sites running VXLANs and their associated underlays. For an overview and how to configure EVPN in your data center network, refer to Ethernet Virtual Private Network-EVPN.
Cumulus NetQ enables operators to view the health of the EVPN service on a networkwide and a per session basis, giving greater insight into all aspects of the service. This is accomplished through two card workflows, one for the service and one for the session and in the NetQ CLI with the netq show evpn command.
Monitor the EVPN Service Networkwide
With NetQ, you can monitor EVPN performance across the network:
Network Services|All EVPN Sessions
Small: view number of nodes running EVPN service and number of alarms
Medium: view number of nodes running EVPN service, number of sessions, and number of alarms
Large: view number of nodes running EVPN service, number of sessions, number of VNIs, switches with the most sessions, and alarms
Full-screen: view all switches, all sessions, and all alarms
netq show evpn command: view configuration and status for all devices, including associated VNI, VTEP address, import and export route (showing BGP ASN and VNI path), and last time a change was made for each device running EVPN
When entering a time value in the netq show lldp command, you must include a numeric value and the unit of measure:
w: week(s)
d: day(s)
h: hour(s)
m: minute(s)
s: second(s)
now
When using the between option, the start time (text-time) and end time (text-endtime) values can be entered as most recent first and least recent second, or vice versa. The values do not have to have the same unit of measure.
View Service Status Summary
You can view a summary of the EVPN service from the NetQ UI or the NetQ CLI.
Open the small Network Services|All EVPN Sessions card. In this example, the number of devices running the EVPN service is six (6) and the number and distribution of related critical severity alarms is zero (0).
To view EVPN service status, run:
netq show evpn
This example shows the Cumulus reference topology, where EVPN runs on all border and leaf switches. Each session is represented by a single row.
cumulus@switch:~$ netq show evpn

View the Distribution of Sessions and Alarms
It is useful to know the number of network nodes running the EVPN protocol over a period of time, as it gives you insight into the amount of traffic associated with and breadth of use of the protocol.
It is also useful to compare the number of nodes running EVPN with the alarms present at the same time to determine if there is any correlation between the issues and the ability to establish an EVPN session. This is visible with the NetQ UI.
Open the medium Network Services|All EVPN Sessions card. In this example there are no alarms, but there are three (3) VNIs.
If a visual correlation is apparent, you can dig a little deeper with the large card tabs.
To view the number of switches running the EVPN service, run:
netq show evpn
Count the switches in the output.
This example shows two border switches and four leaf switches are running the EVPN service, for a total of six (6).

To compare this count with the count at another time, run the netq show evpn command with the around option. Count the devices running EVPN at that time. Repeat with another time to collect a picture of changes over time.
View the Distribution of Layer 3 VNIs
It is useful to know the number sessions between devices and VNIs that are occurring over layer 3, as it gives you insight into the complexity of the VXLAN.
To view this distribution, open the large Network Services|All EVPN Services card and view the bottom chart on the left. In this example, there are 12 layer 3 EVPN sessions running on the three VNIs.
To view the distribution of switches running layer 3 VNIs, run:
netq show evpn
Count the switches using layer 3 VNIs (shown in the VNI and Type columns). Compare that to the total number of VNIs (count these from the VNI column) to determine the ratio of layer 3 versus the total VNIs.
This example shows two (2) layer 3 VNIs (4001 and 4002) and a total of five (5) VNIs (4001, 4002, 10, 20, 30). This then gives a distribution of 2/5 of the total, or 40%.

View Devices with the Most EVPN Sessions
You can view the load from EVPN on your switches and hosts using the large Network Services|All EVPN Sessions card or the NetQ CLI. This data enables you to see which switches are handling the most EVPN traffic currently, validate that is what is expected based on your network design, and compare that with data from an earlier time to look for any differences.
To view switches and hosts with the most EVPN sessions:
Open the large Network Services|All EVPN Sessions card.
Select Top Switches with Most Sessions from the filter above the table.
The table content is sorted by this characteristic, listing nodes running the most EVPN sessions at the top. Scroll down to view those with the fewest sessions.
To compare this data with the same data at a previous time:
Open another large Network Services|All EVPN Sessions card.
Move the new card next to the original card if needed.
Change the time period for the data on the new card by hovering over the card and clicking .
Select the time period that you want to compare with the current time.
You can now see whether there are significant differences between this time period and the previous time period.
You can now see whether there are significant differences between this time and the original time. If the changes are unexpected, you can investigate further by looking at another timeframe, determining if more nodes are now running EVPN than previously, looking for changes in the topology, and so forth.
To determine the devices with the most sessions, run netq show evpn. Then count the sessions on each device.
In this example, border01 and border02 each have 2 sessions. The leaf01-04 switches each have 5 sessions. Therefore the leaf switches have the most sessions.
cumulus@switch:~$ netq show evpn

View Devices with the Most EVPN-related Alarms
Switches experiencing a large number of EVPN alarms may indicate a configuration or performance issue that needs further investigation. You can view the switches sorted by the number of EVPN alarms and then use the Switches card workflow or the Events|Alarms card workflow to gather more information about possible causes for the alarms.
You can view the switches sorted by the number of EVPN alarms and then use the Switches card workflow or the Events|Alarms card workflow to gather more information about possible causes for the alarms.
To view switches with the most EVPN alarms:
Open the large Network Services|All EVPN Sessions card.
Hover over the header and click .
Select Events by Most Active Device from the filter above the table.
The table content is sorted by this characteristic, listing nodes with the most EVPN alarms at the top. Scroll down to view those with the fewest alarms.
Where to go next depends on what data you see, but a few options include:
Hover over the Total Alarms chart to focus on the switches exhibiting alarms during that smaller time slice. The table content changes to match the hovered content. Click on the chart to persist the table changes.
Change the time period for the data to compare with a prior time. If the same switches are consistently indicating the most alarms, you might want to look more carefully at those switches using the Switches card workflow.
Click Show All Sessions to investigate all EVPN sessions networkwide in the full screen card.
To view the switches with the most EVPN alarms and informational events, run the netq show events command with the type option set to evpn, and optionally the between option set to display the events within a given time range. Count the events associated with each switch.
In this example, all EVPN events in the last 24 hours are displayed:
cumulus@switch:~$ netq show events type evpn
No matching event records found
This example shows all EVPN events between now and 30 days ago.
cumulus@switch:~$ netq show events type evpn between now and 30d
No matching event records found

Monitor Virtual Extensible LANs
With NetQ, a network administrator can monitor virtual network components in the data center, including VXLAN and EVPN software constructs. NetQ provides the ability to:
Manage virtual constructs: view the performance and status of VXLANs and EVPN
Validate overlay communication paths
It helps answer questions such as:
Is my overlay configured and operating correctly?
Is my control plane configured correctly?
Can device A reach device B?
Monitor VXLANs
Virtual Extensible LANs (VXLANs) provide a way to create a virtual
network on top of layer 2 and layer 3 technologies. It is intended for
organizations, such as data centers, that require larger scale without
additional infrastructure and more flexibility than is available with
existing infrastructure equipment. With NetQ, you can monitor the
current and historical configuration and status of your VXLANs using the
following command:
netq [<hostname>] show vxlan [vni <text-vni>] [around <text-time>] [json]
netq show interfaces type vxlan [state <remote-interface-state>] [around <text-time>] [json]
netq <hostname> show interfaces type vxlan [state <remote-interface-state>] [around <text-time>] [count] [json]
netq [<hostname>] show events [level info|level error|level warning|level critical|level debug] type vxlan [between <text-time> and <text-endtime>] [json]
When entering a time value, you must include a numeric value and the unit of measure:
w: week(s)
d: day(s)
h: hour(s)
m: minute(s)
s: second(s)
now
For the between option, the start (<text-time>) and end time (text-endtime>) values can be entered as most recent first and least recent second, or vice versa. The values do not have to have the same unit of measure.
View All VXLANs in Your Network
You can view a list of configured VXLANs for all devices, including the
VNI (VXLAN network identifier), protocol, address of associated VTEPs
(VXLAN tunnel endpoint), replication list, and the last time it was
changed. You can also view VXLAN information for a given device by
adding a hostname to the show command. You can filter the results by
VNI.
This example shows all configured VXLANs across the network. In this
network, there are three VNIs (13, 24, and 104001) associated with three
VLANs (13, 24, 4001), EVPN is the virtual protocol deployed, and the
configuration was last changed around 23 hours ago.

Monitor EVPN
EVPN (Ethernet Virtual Private Network) enables network administrators
in the data center to deploy a virtual layer 2 bridge overlay on top of
layer 3 IP networks creating access, or tunnel, between two locations.
This connects devices in different layer 2 domains or sites running
VXLANs and their associated underlays. With NetQ, you can monitor the
configuration and status of the EVPN setup using the netq show evpn
command. You can filter the EVPN information by a VNI (VXLAN network
identifier), and view the current information or for a time in the past.
The command also enables visibility into changes that have occurred in
the configuration during a specific timeframe. The syntax for the
command is:
netq [<hostname>] show evpn [vni <text-vni>] [mac-consistency] [around <text-time>] [json]
netq [<hostname>] show events [level info|level error|level warning|level critical|level debug] type evpn [between <text-time> and <text-endtime>] [json]
When entering a time value, you must include a numeric value and the unit of measure:
w: week(s)
d: day(s)
h: hour(s)
m: minute(s)
s: second(s)
now
For the between option, the start (<text-time>) and end time (text-endtime>) values can be entered as most recent first and least recent second, or vice versa. The values do not have to have the same unit of measure.
For more information about and configuration of EVPN in your data center, refer to the Cumulus Linux EVPN topic.
View the Status of EVPN
You can view the configuration and status of your EVPN overlay across
your network or for a particular device. This example shows the
configuration and status for all devices, including the associated VNI,
VTEP address, the import and export route (showing the BGP ASN and VNI
path), and the last time a change was made for each device running EVPN.
Use the hostname option to view the configuration and status for a

Monitor Application Layer Protocols
The only application layer protocol monitored by NetQ is NTP, the Network Time Protocol.
It is important that the switches and hosts remain in time synchronization with the NetQ appliance or Virtual Machine to ensure collected data is properly captured and processed. You can use the netq show ntp command to view the time synchronization status for all devices or filter for devices that are either in synchronization or out of synchronization, currently or at a time in the past.
The syntax for the show commands is:
netq [<hostname>] show ntp [out-of-sync|in-sync] [around <text-time>] [json]
netq [<hostname>] show events [level info|level error|level warning|level critical|level debug] type ntp [between <text-time> and <text-endtime>] [json]
View Current Time Synchronization Status
You can view the current status of all devices with respect to their time synchronization with a given NTP server, stratum, and application.
This example shows the time synchronization status for all devices in the Cumulus Networks reference architecture. You can see that all border, leaf, and spine switches rely on the out-of-band management server running ntpq to provide their time and that they are all in time synchronization. The out-of-band management server uses the titan.crash-ove server running ntpq to obtain and maintain time synchronization. And the NetQ server uses the eterna.binary.net server running chronyc to obtain and maintain time synchronization. The firewall switches are not time synchronized, which is appropriate. The Stratum value indicates the number of hierarchical levels the switch or host is from reference clock.
When a device is out of time synchronization with the NetQ server, the collected data may be improperly processed. For example, the wrong timestamp could be applied to a piece of data, or that data might be included in an aggregated metric when is should have been included in the next bucket of the aggregated metric. This would make the presented data be slightly off or give an incorrect impression.
This example shows all devices in the network that are out of time synchronization, and consequently need to be investigated.
cumulus@switch:~$ netq show ntp out-of-sync
Matching ntp records:
Hostname NTP Sync Current Server Stratum NTP App
----------------- -------- ----------------- ------- ---------------------
internet no - 16 ntpq
View Time Synchronization for a Given Device
You may only be concerned with the behavior of a particular device. Checking for time synchronization is a common troubleshooting step to take.
This example shows the time synchronization status for the leaf01 switch.
cumulus@switch:~$ netq leaf01 show ntp
Matching ntp records:
Hostname NTP Sync Current Server Stratum NTP App
----------------- -------- ----------------- ------- ---------------------
leaf01 yes kilimanjaro 2 ntpq
View NTP Status for a Time in the Past
If you find a device that is out of time synchronization, you can use the around option to get an idea when the synchronization was broken.
This example shows the time synchronization status for all devices one week ago. Note that there are no errant devices in this example. You might try looking at the data for a few days ago. If there was an errant device a week ago, you might try looking farther back in time.
If a device has difficulty remaining in time synchronization, you might want to look to see if there are any related events.
This example shows there have been no events in the last 24 hours.
cumulus@switch:~$ netq show events type ntp
No matching event records found
This example shows there have been no critical NTP events in the last seven days.
cumulus@switch:~$ netq show events type ntp between now and 7d
No matching event records found
Validate Operations
When you discover operational anomalies, you can validate that the devices, hosts, network protocols and services are operating as expected. You can also compare the current operation with past operation. With NetQ, you can view the overall health of your network at a glance and then delve deeper for periodic checks or as conditions arise that require attention. When issues are present, NetQ makes it easy to identify and resolve them. You can also see when changes have occurred to the network, devices, and interfaces by viewing their operation, configuration, and status at an earlier point in time.
NetQ enables you to validate the:
Overall health of the network
Operation of the network protocols and services running in your network (either on demand or on a scheduled basis)
Configuration of physical layer protocols and services
Validation support is available in the NetQ UI and the NetQ CLI as shown here.

Validation with the NetQ UI
The NetQ UI uses the following cards to create validations and view results for these protocols and services:
Network Health
Validation Request
On-demand and Scheduled Validation Results
For a general understanding of how well your network is operating, the Network Health card workflow is the best place to start as it contains the highest-level view and performance roll-ups. Refer to the NetQ UI Card Reference for details about the components on these cards.
Validation with the NetQ CLI
The NetQ CLI uses the netq check commands to validate the various elements of your network fabric, looking for inconsistencies in configuration across your fabric, connectivity faults, missing configuration, and so forth, and then display the results for your assessment. They can be run from any node in the network.
The NetQ CLI has a number of additional validation features and considerations.
Set a Time Period
You can run validations for a time in the past and output the results in JSON format if desired. The around option enables users to view the network state at an earlier time. The around option value requires an integer plus a unit of measure (UOM), with no space between them. The following are valid UOMs:
UOM
Command Value
Example
day(s)
<#>d
3d
hour(s)
<#>h
6h
minute(s)
<#>m
30m
second(s)
<#>s
20s
If you want to go back in time by months or years, use the equivalent number of days.
Improve Output Readability
You can the readability of the validation outputs using color. Green output indicates successful results and red output indicates results with failures, warnings, and errors. Use the netq config add color command to enable the use of color.
View Default Validation Tests
To view the list of tests run for a given protocol or service by default, use either netq show unit-tests <protocol/service> or perform a tab completion on netq check <protocol/service> [include|exclude]. Refer to Validation Checks for a description of the individual tests.
Select the Tests to Run
You can include or exclude one or more of the various tests performed during the validation. Each test is assigned a number, which is used to identify which tests to run. Refer to Validation Checks for a description of the individual tests. By default, all tests are run. The <protocol-number-range-list> value is used with the include and exclude options to indicate which tests to include. It is a number list separated by commas, or a range using a dash, or a combination of these. Do not use spaces after commas. For example:
include 1,3,5
include 1-5
include 1,3-5
exclude 6,7
exclude 6-7
exclude 3,4-7,9
The output indicates whether a given test passed, failed, or was skipped.
Validation Check Result Filtering
You can create filters to suppress false alarms or uninteresting errors and warnings that can be a nuisance in CI workflows. For example, certain configurations permit a singly-connected CLAG bond and the standard error that is generated is not useful.
Filtered errors and warnings related to validation checks do NOT generate notifications and are not counted in the alarm and info event totals. They are counted as part of suppressed notifications instead.
The filters are defined in the check-filter.yml file in the /etc/netq/ directory. You can create a rule for individual check commands or you can create a global rule that applies to all tests run by the check command. Additionally, you can create a rule specific to a particular test run by the check command.
Each rule must contain at least one match criteria and an action response. The only action currently available is filter. The match can be comprised of multiple criteria, one per line, creating a logical AND. Matches can be made against any column in the validation check output. The match criteria values must match the case and spacing of the column names in the corresponding netq check output and are parsed as regular expressions.
This example shows a global rule for the BGP checks that indicates any events generated by the DataVrf virtual route forwarding interface coming from swp3 or swp7. are to be suppressed. It also shows a test-specific rule to filter all Address Families events from devices with hostnames starting with exit-1 or firewall.
You can configure filters to change validation errors to warnings that would normally occur due to the default expectations of the netq check commands. This applies to all protocols and services, except for Agents. For example, if you have provisioned BGP with configurations where a BGP peer is not expected or desired, you will get errors that a BGP peer is missing. By creating a filter, you can remove the error in favor of a warning.
To create a validation filter:
Navigate to the /etc/netq directory.
Create or open the check_filter.yml file using your text editor of choice.
This file contains the syntax to follow to create one or more rules for one or more protocols or services. Create your own rules, and/or edit and un-comment any example rules you would like to use.
# Netq check result filter rule definition file. This is for filtering
# results based on regex match on one or more columns of each test result.
# Currently, only action 'filter' is supported. Each test can have one or
# more rules, and each rule can match on one or more columns. In addition,
# rules can also be optionally defined under the 'global' section and will
# apply to all tests of a check.
#
# syntax:
#
# <check name>:
# tests:
# <test name, as shown in test list when using the include/exclude and tab>:
# - rule:
# match:
# <column name>: regex
# <more columns and regex.., result is AND>
# action:
# filter
# - <more rules..>
# global:
# - rule:
# . . .
# - rule:
# . . .
#
# <another check name>:
# . . .
#
# e.g.
#
# bgp:
# tests:
# Address Families:
# - rule:
# match:
# Hostname: (^exit*|^firewall)
# VRF: DataVrf1080
# Reason: AFI/SAFI evpn not activated on peer
# action:
# filter
# - rule:
# match:
# Hostname: exit-2
# Reason: SAFI evpn not activated on peer
# action:
# filter

# Hostname: exit-2
# action:
# filter
#
# evpn:
# tests:
# EVPN Type 2:
# - rule:
# match:
# Hostname: exit-1
# action:
# filter
#
Use Validation Commands in Scripts
If you are running scripts based on the older version of the netq check commands and want to stay with the old output, edit the netq.yml file to include old-check: true in the netq-cli section of the file. For example:
Then run netq config restart cli to apply the change.
If you update your scripts to work with the new version of the commands, simply change the old-check value to false or remove it. Then restart the CLI.
Use netq check mlag in place of netq check clag from NetQ 2.4 onward. netq check clag remains available for automation scripts, but you should begin migrating to netq check mlag to maintain compatibility with future NetQ releases.
NetQ provides the information you need to validate the health of your network fabric, devices, and interfaces. Whether you use the NetQ UI or the NetQ CLI to create and run validations, the underlying checks are the same. The number of checks and the type of checks are tailored to the particular protocol or element being validated.

You can focus the data in the table on the right, by unselecting one or more services. Click the checkbox next to the interface item you want to remove from the data. In this example, we have unchecked MTU.
This removes the checkbox next to the associated chart and grays out the title of the chart, temporarily removing the data related to that service from the table. Add it back by hovering over the chart and clicking the checkbox that appears.
View Details of a Particular Interface Service
From the Interface Health tab on the large Network Health card you can click on a chart to take you to the full-screen card pre-focused on that service data.
View All Network Protocol and Service Validation Results
The Network Health card workflow enables you to view all of the results
of all validations run on the network protocols and services during the
designated time period.
To view all the validation results:
Open or locate the Network Health card on your workbench.
Change to the large card using the card size picker.
Click <network protocol or service name> tab in the navigation panel.
Look for patterns in the data. For example, when did nodes, sessions, links, ports, or devices start failing validation? Was it at a specific time? Was it when you starting running the service on more nodes? Did sessions fail, but nodes were fine?
Where to go next depends on what data you see, but a few options include:
Look for matching event information for the failure points in a given protocol or service.
When you find failures in one protocol, compare with higher level protocols to see if they fail at a similar time (or vice versa with supporting services).
Export the data for use in another analytics tool, by clicking and providing a name for the data file.
Validate Network Protocol and Service Operations
NetQ lets you validate the operation of the network protocols and services running in your network either on demand or on a scheduled basis. NetQ provides three NetQ UI card workflows and several NetQ CLI validation commands to accomplish these checks on protocol and service operations:
Validation Request card
Create a new on-demand or scheduled validation request or run a scheduled validation on demand
View a preview of all scheduled validations
On-demand Validation Result card
View the number of devices and sessions tested and their status
View job configuration
Scheduled Validation Result card
View the number and status of runs, filter by failures, paths, and warnings
View job configuration
netq check command
Create and run an on-demand validation
View summary results, individual test status, and protocol or service specific info in the terminal window
netq add validation command
Create an on-demand or scheduled validation
View results on On-demand and Scheduled Validation Result cards
When you want to validate the operation of one or more network protocols and services right now, you can create and run on-demand validations using the NetQ UI or the NetQ CLI.
Create an On-demand Validation for a Single Protocol or Service
You can create on-demand validations that contain checks for a single protocol or service if you suspect that service may have issues.
To create and run a request containing checks on a single protocol or service all within the NetQ UI:
Open the Validation Request card.
Click . Click Validation. Click on card. Click Open Cards.
On the right side of the card, select the protocol or service you want to validate by clicking on its name.
When selected it becomes highlighted and Run Now and Save as New become active. Click the name again to remove it to select a different protocol or service.
This example shows the creation of an on-demand BGP validation.
cumulus@switch:~$ netq add validation type bgp
Running job 7958faef-29e0-432f-8d1e-08a0bb270c91 type bgp
The associated Validation Result card is accessible from the full-screen Validation Request card. Refer to View On-demand Validation Results.
Create an On-demand Validation for Multiple Protocols or Services
You can create on-demand validations that contain checks for more than on protocol or service at the same time using the NetQ UI. This is handy when the protocols are strongly related with respect to a possible issue or if you only want to create one validation request.
To create and run a request containing checks for more than one protocol and/or service:
Open the Validation Request card.
Click . Click Validation. Click on card. Click Open Cards.
On the right side of the card, select the protocols and services you want to validate by clicking on their names.
This example shows the selection of BGP and EVPN.
Click Run Now to start the validation.
The associated on-demand validation result cards (one per protocol and service selected) are accessible from the full-screen Validation Request card. Refer to View On-demand Validation Results.
Create an On-demand Validation with Selected Tests
Using the include <bgp-number-range-list> and exclude <bgp-number-range-list> options of the netq check command, you can include or exclude one or more of the various checks performed during the validation.
First determine the number of the tests you want to include or exclude. Refer to BGP Validation Tests for a description of these tests. Then run the check command.
This example shows a BGP validation that includes only the session establishment and router ID tests. Note that you can obtain the same results using either of the include or exclude options and that the test that is not run is marked as skipped.
cumulus@switch:~$ netq show unit-tests bgp
0 : Session Establishment - check if BGP session is in established state
1 : Address Families - check if tx and rx address family advertisement is consistent between peers of a BGP session
2 : Router ID - check for BGP router id conflict in the network

Refer to Vaildation Examples for similar examples with other protocols and services.
Run an Existing Scheduled Validation On Demand
You may find that although you have a validation scheduled to run at a later time, you would like to run it now.
To run a scheduled validation now:
Open the Validation Request card.
Click . Click Validation. Click on card. Click Open Cards.
Optionally, change to the small or medium card using the card size picker.
Select the validation from the Validation dropdown list.
After you have started an on-demand trace, the results are displayed based on how you created the validation request.
The On-demand Validation Result card workflow enables you to view the results of on-demand validation requests. When a request has started processing, the associated medium Validation Result card is displayed on your workbench with an indicator that it is running. When multiple network protocols or services are included in a validation, a validation result card is opened for each protocol and service. After an on-demand validation request has completed, the results are available in the same Validation Result card/s.
It may take a few minutes for all results to be presented if the load on the NetQ system is heavy at the time of the run.
To view the results:
Locate the medium On-demand Validation Result card on your workbench for the protocol or service that was run.
You can identify it by the on-demand result icon, , protocol or service name, and the date and time that it was run.
Note: You may have more than one card open for a given protocol or service, so be sure to use the date and time on the card to ensure you are viewing the correct card.
Note the total number and distribution of results for the tested devices and sessions (when appropriate). Are there many failures?
Hover over the charts to view the total number of warnings or failures and what percentage of the total results that represents for both devices and sessions.
Switch to the large on-demand Validation Result card using the card size picker.
If there are a large number of device warnings or failures, view the devices with the most issues in the table on the right. By default, this table displays the Most Active devices. Click on a device name to open its switch card on your workbench.
To view the most recent issues, select Most Recent from the filter above the table.
If there are a large number of devices or sessions with warnings or failures, the protocol or service may be experiencing issues. View the health of the protocol or service as a whole by clicking Open <network service> Card when available.
To view all data available for all on-demand validation results for a given protocol, switch to the full screen card.
Double-click in a given result row to open details about the validation.
From this view you can:
See a summary of the validation results by clicking in the banner under the title. Toggle the arrow to close the summary.
See detailed results of each test run to validate the protocol or service. When errors or warnings are present, the nodes and relevant detail is provided.
Export the data by clicking Export.
Return to the validation jobs list by clicking .
You may find that comparing various results gives you a clue as to why certain devices are experiencing more warnings or failures. For example, more failures occurred between certain times or on a particular device.
The results of the netq check command are displayed in the terminal window where you ran the command. Refer to Create On-demand Validations.
After you have run the netq add validation command, you are able to view the results in the NetQ UI.
Open the NetQ UI and log in.
Open the xxxx workbench where the associated On-demand Trace Result card has been placed.
To view more details for this and other traces, refer to Detailed On-demand Trace Results.

Sensors Validation
Perform a Sensors Validation
Hardware platforms have a number sensors to provide environmental data about the switches. Knowing these are all within range is a good check point for maintenance.
For example, if you had a temporary HVAC failure and you are concerned that some of your nodes are beginning to overheat, you can run this validation to determine if any switches have already reached the maximum temperature threshold.

Create Scheduled Validations
When you want to see validation results on a regular basis, it is useful to configure a scheduled validation request to avoid re-creating the request each time. You can create up to 15 scheduled validations for a given NetQ system.
By default a scheduled validation for each protocol and service is run every hour. You do not need to create a scheduled validation for these unless you want it to run at a different interval. Default validations cannot be removed, but are not counted as part of the 15-validation limit.
You can create scheduled validations using the NetQ UI and the NetQ CLI.
Create a Scheduled Validation for a Single Protocol or Service
You might want to create a scheduled validation that runs more often than the default validation if you are investigating an issue with a protocol or service. You might also want to create a scheduled validation that runs less often than the default validation if you are interested in a longer term performance trend. Use the following instructions based on how you want to create the validation.
Open the Validation Request card.
Click . Click Validation. Click on card. Click Open Cards.
On the right side of the card, select the protocol or service you want to validate by clicking on its name.
When selected it becomes highlighted and Run Now and Save as New become active. Click the name again to remove it to select a different protocol or service.
This example shows the selection of BGP.
Enter the schedule frequency (30 min, 1 hour, 3 hours, 6 hours, 12 hours, or 1 day) by selecting it from the Run every list. Default is hourly.
Select the time to start the validation runs, by clicking in the Starting field. Select a day and click Next, then select the starting time and click OK.
Verify the selections were made correctly.
This example shows a scheduled validation for BGP to run avery 12 hours beginning November 12th at 12:15 p.m.
Click Save As New.
Enter a name for the validation.
Spaces and special characters are not allowed in validation request names.
Click Save.
The validation can now be selected from the Validation listing (on the small, medium or large size card) and run immediately using Run Now, or you can wait for it to run the first time according to the schedule you specified. Refer to View Scheduled Validation Results. Note that the number of scheduled validations is now two (15 allowed minus 13 remaining = 2).
To create a scheduled request containing checks on a single protocol or service in the NetQ CLI and view results in the NetQ UI, run:
Create a Scheduled Validation for Multiple Protocols or Services
Sometimes it is useful to run validations on more than one protocol simultaneously. This gives a view into any potential relationship between the protocols or services status. For example, you might want to compare NTP with Agent validations if NetQ Agents are losing connectivity or the data appears to be collected at the wrong time. It would help determine if loss of time synchronization is causing the issue.
You can create simultaneous validations using the NetQ UI. You can come close using the NetQ CLI.
Open the Validation Request card.
Click . Click Validation. Click on card. Click Open Cards.
On the right side of the card, select the protocols and services you want to include in the validation. In this example we have chosen the Agents and NTP services.
Enter the schedule frequency (30 min, 1 hour, 3 hours, 6 hours, 12 hours, or 1 day) by selecting it from the Run every list. Default is hourly.
Select the time to start the validation runs, by clicking in the Starting field. Select a day and click Next, then select the starting time and click OK.
Verify the selections were made correctly.
Click Save As New.
Enter a name for the validation.
Spaces and special characters are not allowed in validation request names.
Click Save.
The validation can now be selected from the Validation listing (on the small, medium or large size card) and run immediately using Run Now, or you can wait for it to run the first time according to the schedule you specified. Refer to View Scheduled Validation Results. Note that the number of scheduled validations is now two (15 allowed minus 13 remaining = 2).
To create simultaneous validations for multiple protocols and services with the NetQ CLI, you create each of the desired validations as quickly as possible so they start as close to the same time. To schedule multiple protocol and service validations, run:
This example creates scheduled validations for Agents and NTP:
cumulus@switch:~$ netq add validation name Agents30m type agents interval 30m
Successfully added Agents30m running every 30m
cumulus@switch:~$ netq add validation name Ntp30m type ntp interval 30m
Successfully added Ntp30m running every 30m
The associated Validation Result cards are accessible from the full-screen Scheduled Validation Result card. Refer to View Scheduled Validation Results.
View Scheduled Validation Results
After creating scheduled validations with either the NetQ UI or the NetQ CLI, the results are shown in the Scheduled Validation Result card. When a request has completed processing, you can access the Validation Result card from the full-screen Validation Request card. Each protocol and service has its own validation result card, but the content is similar on each.
Granularity of Data Shown Based on Time Period
On the medium and large Validation Result cards, the status of the runs is represented in heat maps stacked vertically; one for passing runs, one for runs with warnings, and one for runs with failures. Depending on the time period of data on the card, the number of smaller time blocks used to indicate the status varies. A vertical stack of time blocks, one from each map, includes the results from all checks during that time. The results are shown by how saturated the color is for each block. If all validations during that time period pass, then the middle block is 100% saturated (white) and the warning and failure blocks are zero % saturated (gray). As warnings and errors increase in saturation, the passing block is proportionally reduced in saturation. An example heat map for a time period of 24 hours is shown here with the most common time periods in the table showing the resulting time blocks and regions.

Access and Analyze the Scheduled Validation Results
Once a scheduled validation request has completed, the results are available in the corresponding Validation Result card.
To access the results:
Open the Validation Request card.
Click . Click Validation. Click on card. Click Open Cards.
Change to the full-screen card using the card size picker to view all scheduled validations.
Select the validation results you want to view.
Click (Open Card). This opens the medium Scheduled Validation Result card/s for the selected items.
To analyze the results:
Note the distribution of results. Are there many failures? Are they concentrated together in time? Has the protocol or service recovered after the failures?
Hover over the heat maps to view the status numbers and what percentage of the total results that represents for a given region. The tooltip also shows the number of devices included in the validation and the number with warnings and/or failures. This is useful when you see the failures occurring on a small set of devices, as it might point to an issue with the devices rather than the network service.
Optionally, click Open <network service> Card link to open the medium individual Network Services card. Your current card is not closed.
Switch to the large Scheduled Validation card using the card size picker.
Click to expand the chart.
Collapse the heat map by clicking .
If there are a large number of warnings or failures, view the devices with the most issues by clicking Most Active in the filter above the table. This might help narrow the failures down to a particular device or small set of devices that you can investigate further.
Select the Most Recent filter above the table to see the events that have occurred in the near past at the top of the list.
Optionally, view the health of the protocol or service as a whole by clicking Open <network service> Card (when available).
You can view the configuration of the request that produced the results shown on this card workflow, by hovering over the card and clicking . If you want to change the configuration, click Edit Config to open the large Validation Request card, pre-populated with the current configuration. Follow the instructions in Modify a Scheduled Validation to make your changes.
To view all data available for all scheduled validation results for the given protocol or service, click Show All Results or switch to the full screen card.
Look for changes and patterns in the results. Scroll to the right. Are there more failed sessions or nodes during one or more validations?
Double-click in a given result row to open details about the validation.
From this view you can:
See a summary of the validation results by clicking in the banner under the title. Toggle the arrow to close the summary.
See detailed results of each test run to validate the protocol or service. When errors or warnings are present, the nodes and relevant detail is provided.
Export the data by clicking Export.
Return to the validation jobs list by clicking .
You may find that comparing various results gives you a clue as to why certain devices are experiencing more warnings or failures. For example, more failures occurred between certain times or on a particular device.
Manage Scheduled Validations
You can modify any scheduled validation that you created or remove it altogether at any time. Default validations cannot be removed, modified, or disabled.
Modify a Scheduled Validation
At some point you might want to change the schedule or validation types that are specified in a scheduled validation request.
When you update a scheduled request, the results for all future runs of the validation will be different than the results of previous runs of the validation.
To modify a scheduled validation:
Open the Validation Request card.
Click . Click Validation. Click on card. Click Open Cards.
Select the validation from the Validation dropdown list.
Edit the schedule or validation types.
This example adds EVPN to the validation.
Click Update.
Click Yes to complete the changes, or change the name of the previous version of this scheduled validation.
Click the change name link.
Edit the name.
Click Update.
Click Yes to complete the changes, or repeat these steps until you have the name you want.
The validation can now be selected from the Validation listing (on the small, medium or large size card) and run immediately using Run Now, or you can wait for it to run the first time according to the schedule you specified. Refer to View Scheduled Validation Results.
Delete a Scheduled Validation
You can remove a user-defined scheduled validation at any time using the NetQ UI or the NetQ CLI. Default validations cannot be removed.
Open the Validation Request card.
Click . Click Validation. Click on card. Click Open Cards.
Change to the full-screen card using the card size picker.
Select one or more validations to remove.
Click .
Determine the name of the scheduled validation you want to remove. Run:
This example removes the scheduled validation named Bgp15m.
cumulus@switch:~$ netq del validation Bgp15m
Successfully deleted validation Bgp15m
Repeat these steps for additional scheduled validations you want to remove.
Verify Network Connectivity
It is helpful to verify that communications are freely flowing between the various devices in your network. You can verify the connectivity between two devices in both an ad-hoc fashion and by defining connectivity checks to occur on a scheduled basis. NetQ provides three NetQ UI card workflows and several NetQ CLI trace commands to view connectivity:
Trace Request card
Run a scheduled trace on demand or create new on-demand or scheduled trace request
View a preview of all scheduled traces
On-demand Trace Results card
View source and destination devices, status, paths found, and number/distribution of MTU and hops
View job configuration
Scheduled Trace Results card
View source and destination devices, status, distribution of paths, bad nodes, MTU and hops
View job configuration
netq trace command
Create and run a trace on demand
View source and destination devices, status, paths found, MTU, and hops in terminal window
netq add trace command
Create an on-demand or scheduled trace
View results on On-demand and Scheduled Trace Results cards
Specifying Source and Destination Values
When specifying traces, the following options are available for the source and destination values.
Trace Type
Source
Destination
Layer 2
Hostname
MAC address plus VLAN
Layer 2
IPv4/IPv6 address plus VRF (if not default)
MAC address plus VLAN
Layer 2

MAC address plus VLAN
Layer 3
Hostname
IPv4/IPv6 address
Layer 3
IPv4/IPv6 address plus VRF (if not default)
IPv4/IPv6 address
If you use an IPv6 address, you must enter the complete, non-truncated address.
Additional NetQ CLI Considerations
When creating and running traces using the NetQ CLI, consider the following items.
Time Values
When entering a time value, you must include a numeric value and the unit of measure:
w: week(s)
d: day(s)
h: hour(s)
m: minute(s)
s: second(s)
now
When using the between option, the start time (text-time) and end time (text-endtime) values can be entered as most recent first and least recent second, or vice versa. The values do not have to have the same unit of measure.
Result Display Options
Three output formats are available for the on-demand trace with results in a terminal window.
JSON: Results are listed in a .json file, good for exporting to other applications or software.
Pretty: Results are lined up by paths in a pseudo-graphical manner to help visualize the multiple paths.
Detail: Results are displayed in a tabular format with a row per hop and a set of rows per path, useful for traces with higher hop counts where the pretty output wraps lines,
making it harder to interpret the results. This is the default output when not specified.
You can improve the readability of the output using color as well. Run netq config add color to turn color on. Run netq config del color to turn color off.
Known Addresses
The tracing function only knows about addresses that have already been learned. If you find that a path is invalid or incomplete, you may need to ping the identified device so that its address becomes known.
Create On-demand Traces
You can view the current connectivity between two devices in your network by creating an on-demand trace. These can be performed at layer 2 or layer 3 using the NetQ UI or the NetQ CLI.
Create a Layer 3 On-demand Trace Request
It is helpful to verify the connectivity between two devices when you suspect an issue is preventing proper communication between them. If you cannot find a layer 3 path, you might also try checking connectivity through a layer 2 path.
Determine the IP addresses of the two devices to be traced.
Click (main menu), then IP Addresses under the Network section.
Click and enter a hostname.
Make note of the relevant address.
Filter the list again for the other hostname, and make note of its address.
Open the Trace Request card.
On new workbench: Click in the Global Search box. Type trace. Click on card name.
On current workbench: Click . Click Trace. Click on card. Click Open Cards.
In the Source field, enter the hostname or IP address of the device where you want to start the trace.
In the Destination field, enter the IP address of the device where you want to end the trace.
In this example, we are starting our trace at *leaf01* which has an IPv4 address of 10.10.10.1 and ending it at border01 which has an IPv4 address of *10.10.10.63*. You could have used *leaf01* as the source instead of its IP address.
If you mistype an address, you must double-click it, or backspace over the error, and retype the address. You cannot select the address by dragging over it as this action attempts to move the card to another location.
Use the netq trace command to view the results in the terminal window. Use the netq add trace command to view the results in the NetQ UI.
To create a layer 3 on-demand trace and see the results in the terminal window, run:
netq trace <ip> from (<src-hostname>|<ip-src>) [json|detail|pretty]
Note the syntax requires the destination device address first and then the source device address or hostname.
This example shows a trace from 10.10.10.1 (source, leaf01) to 10.10.10.63 (destination, border01) on the underlay in pretty output. You could have used leaf01 as the source instead of its IP address. The example first identifies the addresses for the source and destination devices using netq show ip addresses then runs the trace.
cumulus@switch:~$ netq border01 show ip addresses
Matching address records:

leaf01 swp52 -- swp1 spine02 swp5 -- swp52 border01 lo
leaf01 swp51 -- swp1 spine01 swp5 -- swp51 border01 lo
Each row of the pretty output shows one of the 12 available paths. Each path is described by hops using the following format:
source hostname and source egress port – ingress port of first hop and device hostname and egress port – n*(ingress port of next hop and device hostname and egress port) – ingress port of destination device hostname
In this example, eight of 12 paths use four hops to get to the destination and four use three hops. The overall MTU for all paths is 9216. No errors or warnings are present on any of the paths.
Alternately, you can choose to view the same results in detail (default output) or JSON format. This example shows the default detail output.
Create a Layer 3 On-demand Trace Through a Given VRF
You can guide a layer 3 trace through a particular VRF interface using the NetQ UI or the NetQ CLI.
To create the trace request:
Determine the IP addresses of the two devices to be traced.
Click (main menu), then IP Addresses under the Network section.
Click and enter a hostname.
Make note of the relevant address and VRF.
Filter the list again for the other hostname, and make note of its address.
Open the Trace Request card.
On new workbench: Click in the Global Search box. Type trace. Click on card name.
On current workbench: Click . Click Trace. Click on card. Click Open Cards.
In the Source field, enter the hostname or IP address of the device where you want to start the trace.
In the Destination field, enter the IP address of the device where you want to end the trace.
In the VRF field, enter the identifier for the VRF associated with these devices.
In this example, we are starting our trace at server01 using its IPv4 address 10.1.10.101 and ending it at server04 whose IPv4 address is 10.1.10.104. Because this trace is between two servers, a VRF is needed, in this case the RED VRF.
Use the netq trace command to view the results in the terminal window. Use the netq add trace command to view the results in the NetQ UI.
To create a layer 3 on-demand trace through a given VRF and see the results in the terminal window, run:
netq trace <ip> from (<src-hostname>|<ip-src>) vrf <vrf> [json|detail|pretty]
Note the syntax requires the destination device address first and then the source device address or hostname.
This example shows a trace from 10.1.10.101 (source, server01) to 10.1.10.104 (destination, server04) through VRF RED in detail output. It first identifies the addresses for the source and destination devices and a VRF between them using netq show ip addresses then runs the trace. Note that the VRF name is case sensitive. The trace job may take a bit to compile all of the available paths, especially if there are a large number of them.
It is helpful to verify the connectivity between two devices when you suspect an issue is preventing proper communication between them. If you cannot find a path through a layer 2 path, you might also try checking connectivity through a layer 3 path.
To create a layer 2 trace request:
Determine the IP or MAC address of the source device and the MAC address of the destination device.
Click (main menu), then IP Neighbors under the Network section.
Click and enter destination hostname.
Make note of the MAC address and VLAN ID.
Filter the list again for the source hostname, and make note of its IP address.
Open the Trace Request card.
On new workbench: Click in the Global Search box. Type trace. Click on card name.
On current workbench: Click . Click Trace. Click on card. Click Open Cards.
In the Source field, enter the hostname or IP address of the device where you want to start the trace.
In the Destination field, enter the MAC address for where you want to end the trace.
In the VLAN ID field, enter the identifier for the VLAN associated with the destination.
In this example, we are starting our trace at server01 with IPv4 address of 10.1.10.101 and ending it at 44:38:39:00:00:3e (server04) using VLAN 10 and VRF RED. Note: If you do not have VRFs beyond the default, you do not need to enter a VRF.
Use the netq trace command to view on-demand trace results in the terminal window.
To create a layer 2 on-demand trace and see the results in the terminal window, run:
netq trace (<mac> vlan <1-4096>) from <mac-src> [json|detail|pretty]
Note the syntax requires the destination device address first and then the source device address or hostname.
This example shows a trace from 44:38:39:00:00:32 (source, server01) to 44:38:39:00:00:3e (destination, server04) through VLAN 10 in detail output. It first identifies the MAC addresses for the two devices using netq show ip neighbors. Then it determines the VLAN using netq show macs. Then it runs the trace.
After you have started an on-demand trace, the results are displayed either in the NetQ UI On-demand Trace Result card or by running the netq show trace results command.
View Layer 3 On-demand Trace Results
View the results for a layer 3 trace based on how you created the request.
After you click Run Now, the corresponding results card is opened on your workbench. While it is working on the trace, a notice is shown on the card indicating it is running.
Once results are obtained, it displays them. Using our example from earlier, the following results are shown:
In this example, we see that the trace was successful. 12 paths were found between the devices, some with three hops and some four hops and with an overall MTU of 9216. Because there is a difference between the minimum and maximum number of hops (as seen in this example) or if the trace failed, you could view the large results card for additional information.
In our example, we can see that paths 9-12 had three hops by scrolling through the path listing in the table. To view the hop details, refer to the next section. If there were errors or warnings, that caused the trace failure, a count would be visible in this table. To view more details for this and other traces, refer to Detailed On-demand Trace Results.
The results of the netq trace command are displayed in the terminal window where you ran the command. Refer to Create On-demand Traces.
After you have run the netq add trace command, you are able to view the results in the NetQ UI.
Open the NetQ UI and log in.
Open the workbench where the associated On-demand Trace Result card has been placed.
View the results for a layer 2 trace based on how you created the request.
After clicking Run Now on the Trace Request card, the corresponding On-demand Trace Result card is opened on your workbench. While it is working on the trace, a notice is shown on the card indicating it is running.
Once the job is completed, the results are displayed.
In the example on the left, we see that the trace was successful. 16 paths were found between the devices, each with five hops and with an overall MTU of 9,000. In the example on the right, we see that the trace failed. Two of the available paths were unsuccessful and a single device may be the problem.
If there was a difference between the minimum and maximum number of hops or other failures, viewing the results on the large card might provide additional information.
In the example on top, we can verify that every path option had five hops since the distribution chart only shows one hop count and the table indicates each path had a value of five hops. Similarly, you can view the MTU data. In the example on the bottom, is an error (scroll to the right in the table to see the count). To view more details for this and other traces, refer to Detailed On-demand Trace Results.
The results of the netq trace command are displayed in the terminal window where you ran the command. Refer to Create On-demand Traces.
After you have run the netq add trace command, you are able to view the results in the NetQ UI.
Open the NetQ UI and log in.
Open the workbench where the associated On-demand Trace Result card has been placed.
You can dig deeper into the results of a trace in the NetQ UI, viewing the interfaces, ports, tunnels, VLANs, etc. for each available path.
To view the more detail:
Locate the On-demand Trace Results card for the trace of interest.
Change to the full-screen card using the card size picker.
Double-click on the trace of interest to open the detail view.
This view provides:
Configuration details for the trace: click the trace above the table
Errors and warnings for all paths: click Errors or Warnings above the table
If the trace was run on a Mellanox switch and drops were detected by the What Just Happened feature, they are also included here.
Path details: walk through the path, host by host, viewing the interfaces, ports, tunnels, VLANs, and so forth used to traverse the network from the source to the destination. Scroll down to view all paths.
If you have a large number of paths, click Load More at the bottom of the details page to view additional path data.
Note that in our example, paths 9-12 have only three hops because they do not traverse through the border02 switch, but go directly from spine04 to border01. Routing would likely choose these paths over the four-hop paths.
Create Scheduled Traces
There may be paths through your network that you consider critical or particularly important to your everyday operations. In these cases, it might be useful to create one or more traces to periodically confirm that at least one path is available between the relevant two devices. You can create scheduled traces at layer 2 or layer 3 in your network, from the NetQ UI and the NetQ CLI.

netq add trace name <text-new-trace-name> <mac> vlan <1-4096> from (<src-hostname> | <ip-src>) [vrf <vrf>] interval <text-time-min>
This example shows the creation of a scheduled trace between server01 (source, 10.1.10.101) and server04 (destination, 44:38:39:00:00:3e) on VLAN 10 with a name of Svr01toSvr04x3Hrs that is run every three hours. The interval option value must be a number of minutes with the units indicator (m).
cumulus@switch:~$ netq add trace name Svr01toSvr04x3Hrs 44:38:39:00:00:3e vlan 10 from 10.1.10.101 interval 180m
Successfully added/updated Svr01toSvr04x3Hrs running every 180m
You may find that, although you have a schedule for a particular trace, you want to have visibility into the connectivity data now. You can run a scheduled trace on demand from the small, medium and large Trace Request cards.
To run a scheduled trace now:
Open the small or medium or large Trace Request card.
Select the scheduled trace from the Select Trace or New Trace Request list. Note: In the medium and large cards, the trace details are filled in on selection of the scheduled trace.
Click Go or Run Now. A corresponding Trace Results card is opened on your workbench.
View Scheduled Trace Results
You can view the results of scheduled traces at any time. Results can be displayed in the NetQ UI or in the NetQ CLI.
The results of scheduled traces are displayed on the Scheduled Trace Result card.
Granularity of Data Shown Based on Time Period
On the medium and large Trace Result cards, the status of the runs is represented in heat maps stacked vertically; one for runs with warnings and one for runs with failures. Depending on the time period of data on the card, the number of smaller time blocks used to indicate the status varies. A vertical stack of time blocks, one from each map, includes the results from all checks during that time. The results are shown by how saturated the color is for each block. If all traces run during that time period pass, then both blocks are 100% gray. If there are only failures, the associated lower blocks are 100% saturated white and the warning blocks are 100% saturated gray. As warnings and failures increase, the blocks increase their white saturation. As warnings or failures decrease, the blocks increase their gray saturation. An example heat map for a time period of 24 hours is shown here with the most common time periods in the table showing the resulting time blocks.

View Detailed Scheduled Trace Results
Once a scheduled trace request has completed, the results are available in the corresponding Trace Result card.
To view the results:
Open the Trace Request card.
Click . Click Trace. Click on card. Click Open Cards.
Change to the full-screen card using the card size picker to view all scheduled traces.
Select the scheduled trace results you want to view.
Click (Open Card). This opens the medium Scheduled Trace Results card(s) for the selected items.
Note the distribution of results. Are there many failures? Are they concentrated together in time? Has the trace begun passing again?
Hover over the heat maps to view the status numbers and what percentage of the total results that represents for a given region.
Switch to the large Scheduled Trace Result card.
If there are a large number of warnings or failures, view the associated messages by selecting Failures or Warning in the filter above the table. This might help narrow the failures down to a particular device or small set of devices that you can investigate further.
Look for a consistent number of paths, MTU, hops in the small charts under the heat map. Changes over time here might correlate with the messages and give you a clue to any specific issues. Note if the number of bad nodes changes over time. Devices that become unreachable are often the cause of trace failures.
View the available paths for each run, by selecting Paths in the filter above the table.
You can view the configuration of the request that produced the results shown on this card workflow, by hovering over the card and clicking . If you want to change the configuration, click Edit to open the large Trace Request card, pre-populated with the current configuration. Follow the instructions in Create a Scheduled Trace Request to make your changes in the same way you created a new scheduled trace.
To view a summary of all scheduled trace results, switch to the full screen card.
Look for changes and patterns in the results for additional clues to isolate root causes of trace failures. Select and view related traces using the Edit menu.
View the details of any specific trace result by clicking on the trace. A new window opens similar to the following:
Scroll to the right to view the information for a given hop. Scroll down to view additional paths. This display shows each of the hosts and detailed steps the trace takes to validate a given path between two devices. Using Path 1 as an example, each path can be interpreted as follows:
Hop 1 is from the source device, server02 in this case.
It exits this device at switch port bond0 with an MTU of 9000 and over the default VRF to get to leaf02.
The trace goes in to swp2 with an MTU of 9216 over the vrf1 interface.
It exits leaf02 through switch port 52 and so on.
Export this data by clicking Export or click to return to the results list to view another trace in detail.
View a Summary of All Scheduled Traces
You can view a summary of all scheduled traces using the netq show trace summary command. The summary displays the name of the trace, a job ID, status, and timestamps for when was run and when it completed.
This example shows all scheduled traces run in the last 24 hours.
cumulus@switch:~$ netq show trace summary

cumulus@switch:~$ netq show trace results f501f9b0-cca3-4fa1-a60d-fb6f495b7a0e
Manage Scheduled Traces
You can modify and remove scheduled traces at any time as described here. An administrator can also manage scheduled traces through the NetQ Management dashboard. Refer to Delete a Scheduled Trace for details.
Modify a Scheduled Trace
After reviewing the results of a scheduled trace for a period of time, you might want to modify how often it is run or the VRF or VLAN used. You can do this using the NetQ UI.
Be aware that changing the configuration of a trace can cause the results to be inconsistent with prior runs of the trace. If this is an unacceptable result, create a new scheduled trace. Optionally you can remove the original trace.
To modify a scheduled trace:
Open the Trace Request card.
Click . Click Trace. Click on card. Click Open Cards.
Select the trace from the New Trace Request dropdown.
Edit the schedule, VLAN or VRF as needed.
Click Update.
Click Yes to complete the changes, or change the name of the previous version of this scheduled trace.
Click the change name link.
Edit the name.
Click Update.
Click Yes to complete the changes, or repeat these steps until you have the name you want.
The validation can now be selected from the New Trace listing (on the small, medium or large size card) and run immediately using Go or Run Now, or you can wait for it to run the first time according to the schedule you specified. Refer to View Scheduled Trace Results.
Remove Scheduled Traces
If you have reached the maximum of 15 scheduled traces for your premises, you might need to remove one trace in favor of another. You can remove a scheduled trace at any time using the NetQ UI or NetQ CLI.
Both a standard user and an administrative user can remove scheduled traces. No notification is generated on removal. Be sure to communicate with other users before removing a scheduled trace to avoid confusion and support issues.
Open the Trace Request card.
Click . Click Trace. Click on card. Click Open Cards.
Change to the full-screen card using the card size picker.
Select one or more traces to remove.
Click .
Determine the name of the scheduled trace you want to remove. Run:
netq show trace summary [name <text-trace-name>] [around <text-time-hr>] [json]
This example shows all scheduled traces in JSON format. Alternately, drop the json option and obtain the name for the standard output.
cumulus@switch:~$ netq del trace leaf01toborder01
Successfully deleted schedule trace leaf01toborder01
Repeat these steps for additional traces you want to remove.
Monitor Using Topology View
The core capabilities of Cumulus NetQ enable you to monitor your network by viewing performance and configuration data about your individual network devices and the entire fabric networkwide. The topics contained in this section describe monitoring tasks that can be performed from a topology view rather than through the NetQ UI card workflows or the NetQ CLI.
Access the Topology View
To open the topology view, click in any workbench header.
This opens the full screen view of your network topology.
This document uses the Cumulus Networks reference topology for all examples.
To close the view, click in the top right corner.
Topology Overview
The topology view provides a visual representation of your Linux network, showing the connections and device information for all monitored nodes, for an alternate monitoring and troubleshooting perspective. The topology view uses a number of icons and elements to represent the nodes and their connections as follows:
Symbol
Usage
Switch running Cumulus Linux OS
Switch running RedHat, Ubuntu, or CentOS
Host with unknown operating system
Host running Ubuntu
Red
Alarm (critical) event is present on the node
Yellow
Info event is present
Lines
Physical links or connections
Interact with the Topology
There are a number of ways in which you can interact with the topology.
Move the Topology Focus
You can move the focus on the topology closer to view a smaller number of nodes, or further out to view a larger number of nodes. As with mapping applications, the node labels appear and disappear as you move in and out on the diagram for better readability. To zoom, you can use:
The zoom controls, , in the bottom right corner of the screen; the ‘+’ zooms you in closer, the ‘-’ moves you further out, and the ‘o’ resets to the default size.
A scrolling motion on your mouse.
Your trackpad.
You can also click anywhere on the topology, and drag it left, right, up, or down to view a different portion of the network diagram. This is especially helpful with larger topologies.
View Data About the Network
You can hover over the various elements to view data about them. Hovering over a node highlights its connections to other nodes, temporarily de-emphasizing all other connections.
Hovering over a line highlights the connection and displays the interface ports used on each end of the connection. All other connections are temporarily de-emphasized.
You can also click on the nodes and links to open the Configuration Panel with additional data about them.
From the Configuration Panel, you can view the following data about nodes and links:
Node Data
Description
ASIC
Name of the ASIC used in the switch. A value of Cumulus Networks VX indicates a virtual machine.
License State
Status of the Cumulus Linux license for the switch; OK, BAD (missing or invalid), or N/A (for hosts).
NetQ Agent Status
Operational status of the NetQ Agent on the switch; Fresh, Rotten.
NetQ Agent Version
Version ID of the NetQ Agent on the switch.
OS Name
Operating system running on the switch.
Platform
Vendor and name of the switch hardware.
Open Card/s
Opens the Event
Number of alarm events present on the switch.
Number of info events present on the switch.
Link Data
Description
Source
Switch where the connection originates
Source Interface
Port on the source switch used by the connection
Target
Switch where the connection ends
Target Interface
Port on the destination switch used by the connection
After reviewing the provided information, click to close the panel, or to view data for another node or link without closing the panel, simply click on that element. The panel is hidden by default.
When no devices or links are selected, you can view the unique count of items in the network by clicking on the on the upper left to open the count summary. Click to close the panel.
You can change the time period for the data as well. This enables you to view the state of the network in the past and compare it with the current state. Click in the timestamp box in the topology header to select an alternate time period.
Hide Events on Topology Diagram
You can hide the event symbols on the topology diagram. Simple move the Events toggle in the header to the left. Move the toggle to the right to show them again.
Export Your NetQ Topology Data
The topology view provides the option to export your topology information as a JSON file. Click Export in the header.
When you discover that devices, hosts, protocols, and services are not operating correctly and validation shows errors, then troubleshooting the issues is the next step. The sections in this topic provide instructions for resolving common issues found when operating Cumulus Linux and NetQ in your network.
Investigate NetQ Issues
Monitoring of systems inevitably leads to the need to troubleshoot and resolve the issues found. In fact network management follows a common pattern as shown in this diagram.
This topic describes some of the tools and commands you can use to troubleshoot issues with the network and NetQ itself. Some example scenarios are included here:
Try looking at the specific protocol or service, or particular devices as well. If none of these produce a resolution, you can capture a log to use in discussion with the Cumulus Networks support team.
Browse Configuration and Log Files
To aid in troubleshooting issues with NetQ, there are the following configuration and log files that can provide insight into the root cause of the issue:
File
Description
/etc/netq/netq.yml
The NetQ configuration file. This file appears only if you installed either the netq-apps package or the NetQ Agent on the system.
/var/log/netqd.log
The NetQ daemon log file for the NetQ CLI. This log file appears only if you installed the netq-apps package on the system.
/var/log/netq-agent.log
The NetQ Agent log file. This log file appears only if you installed the NetQ Agent on the system.
Check NetQ Agent Health
Checking the health of the NetQ Agents is a good way to start troubleshooting NetQ on your network. If any agents are rotten, meaning three heartbeats in a row were not sent, then you can investigate the rotten node. Different views are offered with the NetQ UI and NetQ CLI.
Open the Validation Request card.
Select Default Validation AGENTS from the Validation dropdown.
Click Run Now.
The On-demand Validation Result card for NetQ Agents is placed on your workbench.
In the example below, no NetQ Agents are rotten. If there were nodes with indications of failures, warnings, rotten state, you could use the netq show agents command to view more detail about the individual NetQ Agents:
cumulus@switch:$ netq check agents
agent check result summary:
Total nodes : 21
Checked nodes : 21
Failed nodes : 0
Rotten nodes : 0
Warning nodes : 0
Agent Health Test : passed
cumulus@switch:~$ netq show agents

NetQ provides users with the ability to go back in time to replay the network state, see fabric-wide event change logs and root cause state deviations. The NetQ Telemetry Server maintains data collected by NetQ
agents in a time-series database, making fabric-wide events available for analysis. This enables you to replay and analyze networkwide events for better visibility and to correlate patterns. This allows for root-cause analysis and optimization of network configs for the future.
NetQ provides a number of commands and cards for diagnosing past events.
NetQ records network events and stores them in its database. You can:
View the events through a third-party notification application (Syslog, PagerDuty, Slack, or email)
View the events using the Events|Alarms and Events|Info cards in the NetQ UI, then use the Trace Request card to track the connection between nodes
Use netq show events command to look for any changes made to the runtime configuration that may have triggered the alert, then use netq trace to track the connection between the nodes
The netq trace command traces the route of an IP or MAC address from one endpoint to another. It works across bridged, routed and VXLAN connections, computing the path using available data instead of sending real traffic — this way, it can be run from anywhere. It performs MTU and VLAN consistency checks for every link along the path.
With the NetQ UI or NetQ CLI, you can travel back to a specific point in time or a range of times to help you isolate errors and issues.
All cards have a default time period for the data shown on the card, typically the last 24 hours. You can change the time period to view the data during a different time range to aid analysis of previous or existing issues.
To change the time period for a card:
Hover over any card.
Click in the header.
Select a time period from the dropdown list.
If you think you had an issue with your sensors last night, you can check the sensors on all your nodes around the time you think the issue occurred:
cumulus@switch:~$ netq check sensors around 12h
sensors check result summary:
Total nodes : 13
Checked nodes : 13
Failed nodes : 0
Rotten nodes : 0
Warning nodes : 0
Additional summary:
Checked Sensors : 102
Failed Sensors : 0
PSU sensors Test : passed
Fan sensors Test : passed
Temperature sensors Test : passed
You can travel back in time five minutes and run a trace from spine02 to
exit01, which has the IP address 27.0.0.1:
cumulus@leaf01:~$ netq trace 27.0.0.1 from spine02 around 5m pretty

Trace Paths in a VRF
Use the NetQ UI Trace Request card or the netq trace command to run a trace through a specified VRF as well:
cumulus@leaf01:~$ netq trace 10.1.20.252 from spine01 vrf default around 5m pretty
spine01 -- spine01:swp1 -- leaf01:vlan20
-- spine01:swp2 -- leaf02:vlan20
The opta-support command generates an archive of useful information for troubleshooting issues with NetQ. It is an extension of the cl-support command in Cumulus Linux. It provides information about the NetQ Platform configuration and runtime statistics as well as output from the docker ps command. The Cumulus Networks support team may request the output of this command when assisting with any issues that you could not solve with your own troubleshooting. Run the following command:
cumulus@switch:~$ opta-support
Resolve MLAG Issues
This topic outlines a few scenarios that illustrate how you use NetQ to troubleshoot MLAG on Cumulus Linux switches. Each starts with a log message that indicates the current MLAG state.
NetQ can monitor many aspects of an MLAG configuration, including:
Verifying the current state of all nodes
Verifying the dual connectivity state
Checking that the peer link is part of the bridge
Verifying whether MLAG bonds are not bridge members
Verifying whether the VXLAN interface is not a bridge member
Checking for remote-side service failures caused by systemctl
Checking for VLAN-VNI mapping mismatches
Checking for layer 3 MTU mismatches on peerlink subinterfaces
Checking for VXLAN active-active address inconsistencies
Verifying that STP priorities are the same across both peers
Scenario 1: All Nodes Are Up
When the MLAG configuration is running smoothly, NetQ sends out a message that all nodes are up:
2017-05-22T23:13:09.683429+00:00 noc-pr netq-notifier[5501]: INFO: CLAG: All nodes are up
Running netq show mlag confirms this:
cumulus@switch:~$ netq show mlag

The clag keyword has been deprecated and replaced by the mlag keyword. The
clag keyword continues to work for now, but you should start using the mlag
keyword instead. Keep in mind you should also update any scripts that use the clag
keyword.
When you are logged directly into a switch, you can run clagctl to get
the state:
After you fix the issue, you can show the MLAG state to see if all the nodes are up. The notifications from NetQ indicate all nodes are UP, and the netq check flag also indicates there are no failures.

Network Health Card
As with any network, one of the challenges is keeping track of all of the moving parts. With the NetQ GUI, you can view the overall health of your network at a glance and then delve deeper for periodic checks or as conditions arise that require attention. For a general understanding of how well your network is operating, the Network Health card workflow is the best place to start as it contains the highest view and performance roll-ups.
The Network Health card is located on the default Cumulus workbench. It can also be added to user-created workbenches.

Integrate NetQ API with Your Applications
The NetQ API provides access to key telemetry and system monitoring data gathered about the performance and operation of your network and devices so that you can view that data in your internal or third-party analytic tools. The API gives you access to the health of individual switches, network protocols and services, trace and validation results, and views of networkwide inventory and events.
This guide provides an overview of the NetQ API framework, the basics of using Swagger UI 2.0 or bash plus curl to view and test the APIs. Descriptions of each endpoint and model parameter are contained in individual API .JSON files.
For information regarding new features, improvements, bug fixes, and known issues present in this NetQ release, refer to the release notes.
Inventory and Devices: Address, Inventory, MAC Address tables, Node, Sensors
Events: Events
Each endpoint has its own API. You can make requests for all data and all devices or you can filter the request by a given hostname. Each API returns a predetermined set of data as defined in the API models.
The Swagger interface displays both public and internal APIs. Public APIs do not have internal in their name. Internal APIs are not supported for public use and subject to change without notice.
Get Started
You can access the API gateway and execute requests from the Swagger UI or a terminal interface.
The API is embedded in the NetQ software, making it easy to access from the Swagger UI application.
Select auth from the Select a definition dropdown at the top right of the window. This opens the authorization API.
Open a terminal window.
Continue to Log In instructions.
Log In
While you can view the API endpoints without authorization, you can only execute the API endpoints if you have been authorized.
You must first obtain an access key and then use that key to authorize your access to the API.
Click POST/login.
Click Try it out.
Enter the username and password you used to install NetQ. For this release, the default is username admin and password admin. Do not change the access-key value.
Click Execute.
Scroll down to view the Responses. In the Server response section, in the Response body of the 200 code response, copy the access token in the top line.
Click Authorize.
Paste the access key into the Value field, and click Authorize.
Click Close.
To log in and obtain authorization:
Open a terminal window.
Login to obtain the access token. You will need the following information:
Hostname or IP address, and port (443 for Cloud deployments, 32708 for on-premises deployments) of your API gateway
Your login credentials that were provided as part of the NetQ installation process. For this release, the default is username admin and password admin.
This example uses an IP address of 192.168.0.10, port of 443, and the default credentials:
The output provides the access token as the first parameter.

Copy the access token to a text file for use in making API data requests.
You are now able to create and execute API requests against the endpoints.
By default, authorization is valid for 24 hours, after which users must sign in again and reauthorize their account.
API Requests
You can use either the Swagger UI or a terminal window with bash and curl commands to create and execute API requests.
API requests are easy to execute in the Swagger UI. Simply select the endpoint of interest and try it out.
Select the endpoint from the definition dropdown at the top right of the application.
This example shows the BGP endpoint selected:
Select the endpoint object.
This example shows the results of selecting the GET bgp object:
A description is provided for each object and the various parameters that can be specified. In the Responses section, you can see the data that is returned when the request is successful.
Click Try it out.
Enter values for the required parameters.
Click Execute.
In a terminal window, use bash plus curl to execute requests. Each request contains an API method (GET, POST, etc.), the address and API endpoint object to query, a variety of headers, and sometimes a body. For example, in the log in step above:
API method = POST
Address and API object = “https://<netq.domain>:443/netq/auth/v1/login”
Headers = -H “accept: application/json” and -H “Content-Type: application/json”
Body = -d “{ "username": "admin", "password": "admin", "access_key": "string"}”
API Responses
A NetQ API response is comprised of a status code, any relevant error codes (if unsuccessful), and the collected data (if successful).
The following HTTP status codes might be presented in the API responses:
Code
Name
Description
Action
200

Validate Physical Layer Configuration
Beyond knowing what physical components are deployed, it is valuable to know that they are configured and operating correctly. NetQ enables you to confirm that peer connections are present, discover any misconfigured
ports, peers, or unsupported modules, and monitor for link flaps.
NetQ checks peer connections using LLDP. For DACs and AOCs, NetQ determines the peers using their serial numbers in the port EEPROMs, even if the link is not UP.
Confirm Peer Connections
You can validate peer connections for all devices in your network or for a specific device or port. This example shows the peer hosts and their status for leaf03 switch.
cumulus@switch:~$ netq leaf03 show interfaces physical peer
Matching cables records:
Hostname Interface Peer Hostname Peer Interface State Message
----------------- ------------------------- ----------------- ------------------------- ---------- -----------------------------------
leaf03 swp1 oob-mgmt-switch swp7 up
leaf03 swp2 down Peer port unknown
leaf03 swp47 leaf04 swp47 up
leaf03 swp48 leaf04 swp48 up
leaf03 swp49 leaf04 swp49 up
leaf03 swp50 leaf04 swp50 up
leaf03 swp51 exit01 swp51 up
leaf03 swp52 down Port cage empty
This example shows the peer data for a specific interface port.
cumulus@switch:~$ netq leaf01 show interfaces physical swp47
Matching cables records:
Hostname Interface Peer Hostname Peer Interface State Message
----------------- ------------------------- ----------------- ------------------------- ---------- -----------------------------------
leaf01 swp47 leaf02 swp47 up
Discover Misconfigurations
You can verify that the following configurations are the same on both sides of a peer interface:
Admin state
Operational state
Link speed
Auto-negotiation setting
The netq check interfaces command is used to determine if any of the interfaces have any continuity errors. This command only checks the physical interfaces; it does not check bridges, bonds or other software
constructs. You can check all interfaces at once. It enables you to compare the current status of the interfaces, as well as their status at an earlier point in time. The command syntax is:
netq check interfaces [around <text-time>] [json]
If NetQ cannot determine a peer for a given device, the port is marked as unverified.
If you find a misconfiguration, use the netq show interfaces physical command for clues about the cause.
Find Mismatched Operational States
In this example, we check all of the interfaces for misconfigurations and we find that one interface port has an error. We look for clues about the cause and see that the Operational states do not match on the
connection between leaf 03 and leaf04: leaf03 is up, but leaf04 is down. If the misconfiguration was due to a mismatch in the administrative state, the message would have been Admin state mismatch (up, down) or Admin state mismatch (down, up).
This example uses the and keyword to check the connections between two peers. An error is seen, so we check the physical peer information and discover that the incorrect peer has been specified. After fixing it, we run the check again, and see that there are no longer any interface errors.
This example checks for for configuration mismatches and finds a link speed mismatch on server03. The link speed on swp49 is 40G and the peer port swp50 is unspecified.
This example checks for configuration mismatches and finds auto-negotation setting mismatches between the servers and leafs. Auto-negotiation is off on the leafs, but on on the servers.
