Cumulus® NetQ is a highly-scalable, modern network operations tool set that utilizes telemetry for deep troubleshooting, visibility, and automated workflows from a single GUI interface, reducing maintenance and network downtimes. It combines the ability to easily upgrade, configure and deploy network elements with a full suite of operations capabilities, such as visibility, troubleshooting, validation, trace and comparative look-back functionality.
This documentation is intended for network administrators who are responsible for deploying, configuring, monitoring and troubleshooting the network in their data center or campus environment. NetQ 3.x offers the ability to easily monitor and manage your network infrastructure and operational health. The documentation provides instructions and information about monitoring individual components of the network, the network as a whole, and the NetQ software applications using the NetQ command line interface (NetQ CLI), NetQ (graphical) user interface (NetQ UI), and NetQ Admin UI.
Cumulus NetQ Deployment Guide
This guide is intended for network administrators who are responsible for installation, setup, and maintenance of Cumulus NetQ in their data center environment. NetQ offers the ability to monitor and manage your data center network infrastructure and operational health with simple tools based on open source Linux. This guide provides instructions and information about installing NetQ core capabilities, configuring optional capabilities, and upgrading an existing NetQ installation. This guide assumes you have already installed Cumulus Linux on your network switches and you are ready to add these NetQ capabilities.
Before you get started, you should review the release notes for this version.
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 network-wide 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 network-wide 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 network-wide 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 network-wide 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 Free Range Routing (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 network-wide and complete software
stack basis. For example, you can perform a network-wide 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

Important File Locations
The primary configuration file for all Cumulus NetQ tools, netq.yml,
resides in /etc/netq by default.
Log files are stored in /var/logs/ by default.
Refer to Investigate NetQ Issues
for a complete listing of configuration files and logs for use in issue resolution.
Install NetQ
The complete Cumulus NetQ solution 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).
Install NetQ System Platform
This topic walks you through the NetQ System Platform 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 3.0.x, you must first decide whether you want to install the NetQ Platform 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.

KVM Example Configuration
This example shows the VM setup process for a system with Libvirt and KVM/QEMU installed.
Confirm that the SHA256 checksum matches the one posted on the NVIDIA Application Hub to ensure the image download has not been corrupted.
Copy the QCOW2 image to a directory where you want to run it.
Tip: Copy, instead of moving, the original QCOW2 image that was downloaded to avoid re-downloading it again later should you need to perform this process again.
Replace the disk path value with the location where the QCOW2 image is to reside. Replace network model value (eth0 in the above example) with the name of the interface where the VM is connected to the external network.
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
Verify the platform is ready for installation. Fix any errors indicated before installing the NetQ software.
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.

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.

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: CumulusLinux!
Change the password using the passwd command:
cumulus@hostname:~$ passwd
Changing password for cumulus.
(current) UNIX password: CumulusLinux!
Enter new UNIX password:
Retype new UNIX password:
passwd: password updated successfully
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:

cumulus@hostname:~$ sudo opta-check
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.

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:
# This file describes the network interfaces available on your system
# For more information, see netplan(5).
network:
version: 2
renderer: networkd
ethernets:
eno1:
dhcp4: no
addresses: [192.168.1.222/24]
gateway4: 192.168.1.1
nameservers:
addresses: [8.8.8.8,8.8.4.4]
Apply the settings.
cumulus@hostname:~$ sudo netplan apply
Repeat these steps for each of the worker node appliances.
Verify NetQ Software and Appliance Readiness
Now that the appliances are up and running, verify that the software is available and each appliance is ready for installation.
On the master NetQ Cloud Appliance, verify that the needed packages are present and of the correct release, version 3.0.0 and update 27 or later.
cumulus@hostname:~$ dpkg -l | grep netq
ii netq-agent 3.0.0-ub18.04u27~1588242914.9fb5b87_amd64 Cumulus NetQ Telemetry Agent for Ubuntu
ii netq-apps 3.0.0-ub18.04u27~1588242914.9fb5b87_amd64 Cumulus NetQ Fabric Validation Application for Ubuntu
Verify the installation images are present and of the correct release, version 3.0.0.
cumulus@hostname:~$ cd /mnt/installables/
cumulus@hostname:/mnt/installables$ ls
NetQ-3.0.0-opta.tgz netq-bootstrap-3.0.0.tgz
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.
On one of your worker NetQ Cloud Appliances, verify that the needed packages are present and of the correct release, version 3.0.0 and update 27 or later.
cumulus@hostname:~$ dpkg -l | grep netq
ii netq-agent 3.0.0-ub18.04u27~1588242914.9fb5b87_amd64 Cumulus NetQ Telemetry Agent for Ubuntu
ii netq-apps 3.0.0-ub18.04u27~1588242914.9fb5b87_amd64 Cumulus NetQ Fabric Validation Application for Ubuntu
Prepare Your Existing NetQ Appliances for a NetQ 3.0 Deployment
This topic describes how to prepare a NetQ 2.4.x or earlier NetQ Appliance before installing NetQ 3.0.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 3.0.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.
# This file describes the network interfaces available on your system
# For more information, see netplan(5).
network:
version: 2
renderer: networkd
ethernets:
eno1:
dhcp4: yes
Apply the settings.
$ sudo netplan apply
Create and/or edit the /etc/netplan/01-ethernet.yaml Netplan configuration file.
In this example the interface, eno1, is given a static IP address of 192.168.1.222 with a gateway at 192.168.1.1 and DNS server at 8.8.8.8 and 8.8.4.4.
# This file describes the network interfaces available on your system
# For more information, see netplan(5).
network:
version: 2
renderer: networkd
ethernets:
eno1:
dhcp4: no
addresses: [192.168.1.222/24]
gateway4: 192.168.1.1
nameservers:
addresses: [8.8.8.8,8.8.4.4]
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 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-2.2 - use that instead.
Select 3.0 from the Version list, and then select 3.0.0 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-3.0.0.tgz and either NetQ-3.0.0.tgz (on-premises) or NetQ-3.0.0-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-3.0.0-opta.tgz instead of NetQ-3.0.0.tgz.
cumulus@<hostname>:~$ dpkg -l | grep netq
ii netq-agent 3.0.0-ub18.04u27~1588242914.9fb5b87_amd64 Cumulus NetQ Telemetry Agent for Ubuntu
ii netq-apps 3.0.0-ub18.04u27~1588242914.9fb5b87_amd64 Cumulus NetQ Fabric Validation Application for Ubuntu
cumulus@<hostname>:~$ cd /mnt/installables/
cumulus@<hostname>:/mnt/installables$ ls
NetQ-3.0.0.tgz netq-bootstrap-3.0.0.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 NetQ System Platform for a new appliance.
You can now install the NetQ software using the Admin UI.
This is the final set of steps for installing NetQ. If you have not already performed the installation preparation steps, go to Install NetQ System Platform before continuing here.
To install NetQ:
Log in to your NetQ On-premises Appliance, NetQ Cloud Appliance, the master node of your cluster, or VM.
In your browser address field, enter https://<hostname-or-ipaddr>:8443.
This opens the Admin UI.
Step through the UI.
Having made your installation choices during the preparation steps, you can quickly select the correct path through the UI.
Select your deployment type.
Choose which type of deployment model you want to use. Both options provide secure access to data and features useful for monitoring and troubleshooting your network.
Select your install method.
Choose between restoring data from a previous version of NetQ or performing a fresh installation.
Fresh Install: Continue with Step c.
Maintain Existing Data (on-premises only): If you have created a backup of your NetQ data, choose this option.
If you are moving from a standalone to a server cluster arrangement, you can only restore your data one time. After the data has been converted to the cluster schema, it cannot be returned to the single server format.
Select your server arrangement.
Select whether you want to deploy your infrastructure as a single stand-alone server or as a cluster of servers. One master and two worker nodes are supported for the cluster deployment.
Select arrangement
If you select a server cluster, use the private IP addresses that you used when setting up the worker nodes to add those nodes.
Add worker nodes to a server cluster
Install NetQ software.
You install the NetQ software using the installation files (NetQ-3.0.0.tgz for on-premises deployments or NetQ-3.0.0-opta.tgz for cloud deployments) that you downloaded and stored previously.
Enter the appropriate filename in the field provided.
Activate NetQ.
This final step activates the software and enables you to view the health of your NetQ system. For cloud deployments, you must enter your configuration key.
On-premises activation
Cloud activation
View the system health.
When the installation and activation is complete, the NetQ System Health dashboard is visible for tracking the status of key components in the system. Single server deployments display two cards, one for the server, and one for Kubernetes pods. Server cluster deployments display additional cards, including one each for the Cassandra database, Kafka, and Zookeeper services.
On-premises deployment
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 NetQ System Platform 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-3.0.0.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 3.0.0 software, you should install the corresponding NetQ 3.0.0 Agent on each switch and server you want to monitor. There are important features and fixes included in the NetQ Agent with each release.
Use the instructions in the following sections based on the OS installed on the switch or server.
Install and Configure the NetQ Agent on Cumulus Linux Switches
After installing your Cumulus NetQ software, you should install the NetQ 3.0.0 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-3.0
...
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-3.0
...
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 3.0.0 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
The following packages, while not required for installation of the NetQ Agent, must be installed and running for proper operation of the NetQ Agent on an Ubuntu server:
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.
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.
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.

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
If the CLI is configured, you can use it to configure the NetQ Agent to send telemetry data to the NetQ Server or Appliance. If it is not configured, refer to Configure the NetQ CLI on an Ubuntu Server and then return here.
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:

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 on RHEL and CentOS Servers
After installing your Cumulus NetQ software, you should install the NetQ 3.0.0 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
The following packages, while not required for installation of the NetQ Agent, must be installed and running for proper operation of the NetQ Agent on a Red Hat or CentOS server:
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 3.0.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 3.0.0 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-3.0
...
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-3.0
...
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.
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.
cumulus@switch:~$ sudo netq config add cli server api.netq.cumulusnetworks.com access-key 123452d9bc2850a1726f55534279dd3c8b3ec55e8b25144d4739dfddabe8149e secret-key /vAGywae2E4xVZg8F+HtS6h6yHliZbBP6HXU3J98765= premises datacenterwest

cumulus@switch:~$ netq config restart cli
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 3.0.0 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-2.4 - use that instead.
Install NetQ CLI on an Ubuntu Server
A simple process installs the NetQ CLI on an Ubuntu server.
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.

Upgrade NetQ
This topic describes how to upgrade from your current NetQ 2.4.x installation to the NetQ 3.0.0 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 3.0.0, 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.x installation to NetQ 3.0.0 is to upgrade either the NetQ Platform software running on your NetQ On-premises Appliance(s) or VM(s), or the NetQ Collector software running on your NetQ Cloud Appliance(s) or VM(s).
Prepare for Upgrade
Two important steps are required to prepare for upgrade of your NetQ software:
Download the necessary software tarballs
Update the Debian packages on Appliance(s) and VM(s)
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 2.4.x data. Refer to Back Up Your NetQ Data.
Select 3.0 from the Version list, and then click 3.0.0 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-3.0.0.tgz file. If you are upgrading NetQ Collector software for a NetQ Cloud Appliance or VM, select Appliance (Cloud) to download the NetQ-3.0.0-opta.tgz file.
Scroll down and click Download on the relevant image card.
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-3.0 as followed
cat /etc/apt/sources.list.d/cumulus-netq.list
deb [arch=amd64] https://apps3.cumulusnetworks.com/repos/deb bionic netq-3.0
Update the NetQ debian packages using the following three commands.
cumulus@<hostname>:~$ sudo dpkg --remove --force-remove-reinstreq cumulus-netq netq-apps netq-agent 2>/dev/null
[sudo] password for cumulus:

Now that you have all of the software components prepared, you can upgrade your NetQ On-premises Appliance or VM, or your NetQ Cloud Appliance or VM, using the NetQ Admin UI, in the next section. Alternately, you can upgrade using the CLI here: Upgrade Using the NetQ CLI.
Upgrade Using the NetQ Admin UI
Upgrading your NetQ On-premises or Cloud Appliance(s) or VMs is simple using the Admin UI.
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 3.0.0, doing so gives you access to new features and important bug fixes. Refer to the release notes for details.
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:
[Fri 26 Jul 2019 02:35:35 PM UTC] - Received Inputs for backup ...
[Fri 26 Jul 2019 02:35:36 PM UTC] - Able to find cassandra pod: cassandra-0

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 in Back Up Your NetQ Data. 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 ...
WARNING: Restore procedure wipes out the existing contents of Database.
Once the Database is restored you loose the old data and cannot be recovered.

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 installation or upgrade of NetQ is complete, there are a few additional configuration tasks that might be required.
Add More Nodes to Your Server Cluster
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.
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.
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.
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 and configure NetQ event notifications with popular notification applications
integrate with your LDAP server to use existing user accounts in NetQ
integrate with Grafana to view interface statistics graphically
integrate with customer applications using the Cumulus NetQ API
Integrate NetQ with Notification Applications
After you have installed the NetQ applications package and the NetQ Agents,
you may want to configure some of the additional capabilities that NetQ
offers. This topic describes how to integrate NetQ with an event notification application.
Integrate NetQ with an Event Notification Application
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 and Slack tools.
You may integrate with one or more of these applications simultaneously.
Each network protocol and service in the NetQ Platform receives the raw
data stream from the NetQ Agents, processes the data and delivers events
to the Notification function. Notification then stores, filters and
sends messages to any configured notification applications. Filters are
based on rules you create. You must have at least one rule per filter. A select set of events can be triggered by a user-configured threshold.
You may choose to implement a proxy server (that sits between the NetQ
Platform 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.
In either case, notifications are generated for the following types of
events:

* This type of event can only be viewed in the CLI with this release.
Refer to the Events Reference for descriptions and examples of these events.
Event Message Format
Messages have the following structure:
<message-type><timestamp><opid><hostname><severity><message>
Identifier of the service or process that generated the event
hostname
Hostname of network device where event occurred
severity
Severity level in which the given event is classified; debug, error, info, warning, or critical
message
Text description of event
For example:
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 CLI in the following order:
Notification Commands Overview
The NetQ Command Line Interface (CLI) is used to filter and send notifications to third-party tools based on severity, service, event-type, and device. You can use TAB completion or the help option to assist when needed.
##Proxy
netq add notification proxy <text-proxy-hostname> [port <text-proxy-port>]
netq show notification proxy
netq del notification proxy
The various command options are described in the following sections where they are used.
Configure Basic NetQ Event Notification
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 (slack, pagerduty, syslog)
Add a rule that accepts all interface events
Add a filter that associates this rule with the newly created channel
Create Your Channel
For Pager Duty:
Configure a channel using the integration key for your Pager Duty setup. Verify the configuration.
cumulus@switch:~$ netq add notification channel pagerduty pd-netq-events integration-key c6d666e210a8425298ef7abde0d1998

NetQ is now configured to send all interface events to your selected channel.
Configure Advanced NetQ Event Notifications
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.To configure the proxy server:
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
Successfully overwrote notifier proxy to null
Create Channels
Create one or more PagerDuty, Slack, or syslog channels to present the
notifications.
Configure a PagerDuty Channel
NetQ sends notifications to PagerDuty as PagerDuty events.
For example:
To configure the NetQ notifier to send notifications to PagerDuty:
Configure the following options using the netq add notification channel command:
Option
Description
CHANNEL_TYPE <text-channel-name>
The third-party notification channel and name; use pagerduty in this case.
integration-key <text-integration-key>
The integration key is also called the service_key or routing_key. The default is an empty string ("").
severity
(Optional) The log level to set, which can be one of info, warning, error, critical or debug. The severity defaults to info.
cumulus@switch:~$ netq show notification channel
Matching config_notify records:
Name Type Severity Channel Info
--------------- ---------------- ---------------- ------------------------
pd-netq-events pagerduty info integration-key: c6d666e
210a8425298ef7abde0d1998
Configure a Slack Channel
NetQ Notifier sends notifications to Slack as incoming webhooks for a
Slack channel you configure. For example:
To configure NetQ to send notifications to Slack:
If needed, create one or more Slack channels on which to receive the
notifications.
Click + next to Channels.
Enter a name for the channel, and click Create Channel.
Navigate to the new channel.
Click + Add an app link below the channel name to open the
application directory.
In the search box, start typing incoming and select **
Incoming WebHooks when it appears.
Click Add Configuration and enter the name of the channel
you created (where you want to post notifications).
Click Add Incoming WebHooks integration.
Save WebHook URL in a text file for use in next step.
Configure the following options in the netq config add notification channel command:
Option
Description
CHANNEL_TYPE <text-channel-name>
The third-party notification channel name; use slack in this case.
WEBHOOK
Copy the WebHook URL from the text file OR in the desired channel, locate the initial message indicating the addition of the webhook, click incoming-webhook link, click Settings.
Example URL: https://hooks.slack.com/services/text/moretext/evenmoretext
severity
The log level to set, which can be one of error, warning, info, or debug. The severity defaults to info.
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.
Verify the channel is configured correctly.

From the Slack Channel:
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 the PagerDuty or
Slack 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 PagerDuty
and/or Slack 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:

Examples of Advanced Notification Configurations
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. Refer to Integrate NetQ with an Event Notification Application for details and instructions for creating channels, rules, and filters.
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.
cumulus@switch:~$ netq add notification channel pagerduty pd-netq-events integration-key 1234567890

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.

Create a Notification for When a Service Goes Down
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 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.
Remove an Event Notification Channel
You can delete an event notification integration using the netq config del notification command. You can verify it has been removed using the
related show command.
For example, to remove a Slack integration and verify it is no longer in
the configuration:
cumulus@switch:~$ netq del notification channel slk-netq-events
cumulus@switch:~$ netq show notification channel

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, and ACL events.
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:
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 (syslog, Slack, or PagerDuty), create them by following the instructions in Create Your 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 using the netq add tca command. Note that the event ID is case sensitive and must be in all caps.
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 add a critical severity to the CPU utilization rule you created earlier:
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.
Suppress a Rule
During troubleshooting or maintenance of switches you may want to suppress a rule to prevent erroneous event messages. 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.
For example, to suppress the disk utilization event for an hour:
Once you have created a bunch of rules, you might to manage them; view a list of the rules, disable a rule, delete a rule, and so forth.
Show Threshold-based Event Rules
You can view all TCA rules or a particular rule using the netq show tca command:

Disable a TCA Rule
Where the suppress option temporarily disables a TCA rule, you can use the is_active option to disable a rule indefinitely. To disable a rule, set the option to false. To reenable it, set the option to true.
If disabling a rule is not sufficient, and you want to remove a rule altogether, you can do so using the netq del tca command.
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

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 the Overview to become familiar with LDAP configuration parameters, or skip to Create an LDAP Configuration if you are already an LDAP expert.
Overview
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.
Example LDAP Configurations
A variety of example configurations are provided here. Scenarios 1-3 are based on using an OpenLDAP or similar authentication service. Scenario 4 is based on using the Active Directory service for authentication.
Scenario 1: Base Configuration
In this scenario, we are configuring the LDAP server with anonymous authentication, a User ID based on an email address, and a search scope of base.

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 Server or Appliance.
NetQ only collects statistics for physical interfaces; it does not collect statistics for virtual (non-physical) interfaces, such as bonds, bridges, and VXLANs. Specifically, the NetQ Agent collects the following interface statistics:
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.
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.
Cumulus in the Cloud (CITC): air.netq.cumulusnetworks.com
Enter your credentials (the ones used to login)
For cloud deployments only, if you have more than one premises configured, you can select the premises you want to view, as follows:
If you leave the Premises field blank, the first premises name is selected by default
If you enter a premises name, that premises is selected for viewing
Note: If multiple premises are configured with the same name, then the first premises of that name is selected for viewing
Click Save & Test
Create Your NetQ Dashboard

Cumulus NetQ API User Guide
The NetQ API provides access to key telemetry and system monitoring data
gathered about the performance and operation of your data center 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, and views of
network-wide inventory and events.
This guide provides an overview of the API framework and some examples
of how to use the API to extract the data you need. Descriptions of each
endpoint and model parameter are contained in the API .json files.
For information regarding new features, improvements, bug fixes, and
known issues present in this release, refer to the
release notes.
Copy the access token for use in making data requests.
API Requests
We will use curl to execute our requests. Each request contains an API
method (GET, POST, etc.), the address and API object to query, a variety
of headers, and sometimes a body. In the log in step you used above:
API method = POST
Address and API object = “https://<netq.domain>:32708/netq/auth/v1/login”
Headers = -H “Content-Type: application/json”
Body = -d ‘{“username”:“admin”,“password”:“admin”}’
We have used the insecure option to work around any certificate issues
with our development configuration. You would likely not use this
option.
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
Success
Request was successfully processed.
Review response
400
Bad Request
Invalid input was detected in request.
Check the syntax of your request and make sure it matches the schema
401
Unauthorized
Authentication has failed or credentials were not provided.
Provide or verify your credentials, or request access from your administrator
403
Forbidden
Request was valid, but user may not have needed permissions.
Verify your credentials or request an account from your administrator
404
Not Found
Requested resource could not be found.
Try the request again after a period of time or verify status of resource
409
Conflict
Request cannot be processed due to conflict in current state of the resource.
Verify status of resource and remove conflict
500
Internal Server Error

Example Requests and Responses
Some command requests and their responses are shown here, but feel free
to run your own requests. To run a request, you will need your
authorization token. We have piped our responses through a python tool
to make the responses more readable. You may chose to do so as well or
not.
To view all of the endpoints and their associated requests and
responses, refer to Cumulus NetQ API User Guide.
Get Network-wide Status of the BGP Service
Make your request to the bgp endpoint to obtain status information
from all nodes running the BGP service, as follows:
Make your request to the interfaces endpoint to view the status of all
interfaces. By specifying the eq-timestamp option and entering a date
and time in epoch format, you indicate the data for that time (versus in
the last hour by default), as follows:
For simplicity, all of the endpoint APIs are combined into a single
json-formatted file. There have been no changes to the file in the NetQ 3.0.0 release.

Cumulus NetQ UI User Guide
This guide is intended for network administrators and operators who are
responsible for monitoring and troubleshooting the network in their data
center environment. NetQ 2.x offers the ability to easily monitor and
manage your data center network infrastructure and operational health.
This guide provides instructions and information about monitoring
individual components of the network, the network as a whole, and the
NetQ software itself using the NetQ graphical user interface (GUI). If
you prefer to use a command line interface, refer to the
Cumulus NetQ CLI User Guide.
NetQ User Interface Overview
The NetQ 2.x graphical user interface (UI) enables you to access NetQ capabilities through a web browser as opposed to through a terminal window using the Command Line Interface (CLI). Visual representations of the health of the network, inventory, and system events make it easy to both find faults and misconfigurations, and to fix them.
The UI is accessible in both on-site and in-cloud deployments. It is supported on Google Chrome. Other popular browsers may be used, but have not been tested and may have some presentation issues.
Before you get started, you should refer to the release notes for this version.
Access the NetQ UI
Logging in to the NetQ UI is as easy as opening any web page.
To log in to the UI:
Open a new Internet browser window or tab.
Enter the following URL into the Address bar for the NetQ On-premises Appliance or VM, or the NetQ Cloud Appliance or VM:
NetQ Cloud: Use credentials provided by Cumulus via email titled Welcome to Cumulus NetQ!
Enter your username.
Enter your password.
Enter a new password.
Enter the new password again to confirm it.
Click Update and Accept after reading the Terms of Use.
The default Cumulus Workbench opens, with your username shown in the upper right corner of the application.
Enter your username.
Enter your password.
The user-specified home workbench is displayed. If a home workbench is not specified, then the Cumulus Default workbench is displayed.
Any workbench can be set as the home workbench. Click (User Settings), click Profiles and Preferences, then on the Workbenches card click to the left of the workbench name you want to be your home workbench.
To log out of the UI:
Click at the top right of the application.
Select Log Out.
Application Layout
The NetQ UI contains two main areas:
Application Header (1): Contains the main menu, recent actions history, search capabilities, NetQ version, quick health status chart, local time zone, premises list (cloud-only), and user account information.
Workbench (2): Contains a task bar and content cards (with status and configuration information about your network and its various components).
Main Menu
Found in the application header, click to open the main menu which provides navigation to:
Favorites: contains link to the user-defined favorite workbenches; Home is points to the Cumulus Workbench until reset by a user
NetQ: contains links to all workbenches
Network: contains links to tabular data about various network elements and the What Just Happened feature
Admin: contains links to application management and lifecycle management features (only visible to users with Admin access role)
Notifications: contains link to threshold-based event rules and notification channels
Recent Actions
Found in the header, Recent Actions keeps track of every action you take on your workbench and then saves each action with a timestamp. This enables you to go back to a previous state or repeat an action.
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. 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 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.
Embedded Application Help
The NetQ UI provides guided walk-throughs for selected tasks and links to additional resources.
You must have connection to the Internet to access this feature.
Click Need Help? to open the menu of tasks and resources currently available.
Is the help button covering content that you want to see?
The button can be dragged and dropped to various locations around the edge of the UI, so if you do not like it on the bottom left (default), you can move it to the bottom center, bottom right, right side bottom, etc. A green dashed border appears in the locations where it can be placed. Alternately, enlarge the NetQ UI application window or scroll within the window to view any hidden content.
Within the help menu, topics are grouped by categories:
General: These items describe or walk you through high-level tasks or information about the NetQ UI.
How to…: These items walk you through how to perform common tasks.
Tell me about…: These items describe features of the application.
Where Can I Find…: These items help you find and use features that may be harder to find than others in the application.
User Documentation: This provides a link to the Cumulus NetQ user documentation. It opens in a separate window so you can have it open while working in the application.
You can search for help items by collapsing and expanding categories or by searching. Click a category title to toggle between viewing and hiding the content. To search, begin entering text into the Search field to see suggested content.

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 may
provide 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 application. 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 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
etc.
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: network-wide 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): network-wide validation of network protocols and services
Trace Request (and Results): find available paths between two devices in the network fabric
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.
Look for an “Add: <card name>” item.
If it is still available, click the item.
The card appears on the current workbench, at the bottom.
The card appears on the current workbench, at the bottom.
To access the card workflow by searching for the card:
Click in the Global Search field.
Begin typing the name of the card.
Select it from the list.
The card appears on a current workbench, at the bottom.
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.

Monitor Events
Two event workflows, the Alarms card workflow and the Info card
workflow, provide a view into the events occurring in the network. The
Alarms card workflow tracks critical severity events, whereas the Info
card workflow tracks all warning, info, and debug severity events.
To focus on events from a single device perspective, refer to
Monitor Switches.
Monitor Critical Events
You can easily monitor critical events occurring across your network using the Alarms card. You can determine the number of events for the various system, interface, and network protocols and services components in the network. The content of the cards in the workflow is described first, and then followed by common tasks you would perform using this card workflow.

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 i 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 view.
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 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.
Monitor Informational Events
You can easily monitor warning, info, and debug severity events occurring across your network using the Info card. You can determine the number of events for the various system, interface, and network
protocols and services components in the network. The content of the cards in the workflow is described first, and then followed by common tasks you would perform using this card workflow.

Message: Text describing the alarm or info event that occurred
Type: Name of network protocol and/or service that triggered the given event
Severity: Importance of the event-critical, warning, info, or debug
Table Actions
Select, export, or filter the list. Refer to Table Settings.
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 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
To return to your workbench, click in the top right corner of the card.

Monitor Network Performance
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 network-wide. The topics contained in this section describe monitoring tasks that apply across the entire network. For device-specific monitoring refer to Monitor Devices.
Monitor Network Health
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.

View Network Health Summary
Overall network health is based on successful validation results. The summary includes the percentage of successful results, a trend indicator, and a distribution of the validation results.
To view a summary of your network health, open the small Network Health card.
In this example, the overall health is relatively good, but improving compared to recent status. Refer to the next section for viewing the key health metrics.
View Key Metrics of Network Health
Overall network health is a calculated average of several key health metrics: System, Network Services, and Interface health.
To view these key metrics, open the medium Network Health card. Each metric is shown with percentage of successful validations, a trend indicator, and a distribution of the validation results.
In this example, the health of each of the system and network services are good, but interface health is on the lower side. While it is improving, you might choose to dig further if it does not continue to improve. Refer to the following section for additional details.
View System Health
The system health is a calculated average of the NetQ Agent, Cumulus Linux license, and sensor health metrics. In all cases, validation is performed on the agents and licenses. If you are monitoring platform sensors, the calculation includes these as well. You can view the overall health of the system from the medium Network Health card and information about each component from the System Health tab on the large Network Health card.

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 the full screen Network Health card.
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
With the NetQ UI, you can validate the operation of the network protocols and services running in your network either on demand or on a scheduled basis. There are three card workflows to perform this validation: one for creating the validation request (either on-demand or scheduled) and two validation results (one for on-demand and one for scheduled).
This release supports validation of the following network protocols and services: Agents, BGP, CLAG, EVPN, Interfaces, License, MTU, NTP, OSPF, Sensors, VLAN, and VXLAN.
For a more general understanding of how well your network is operating, refer to the Monitor Network Health topic.

Name: Text identifier of the validation
Type: Name of network protocols and/or services included in the validation
Start Time: Data and time that the validation request was run
Last Modified: Date and time of the most recent change made to the validation request
Cadence (Min): How often, in minutes, the validation is scheduled to run. This is empty for new on-demand requests.
Is Active: Indicates whether the request is currently running according to its schedule (true) or it is not running (false)
Table Actions
Select, export, or filter the list. Refer to Table Settings.
Create On-demand and Scheduled Validation Requests
There are several types of validation requests that a user can make. Each has a slightly different flow through the Validation Request card,
and is therefore described separately. The types are based on the intent of the request:
When you want to validate the operation of one or more network protocols and services right now, you can create and run an on-demand validation
request using the large Validation Request card.
To create and run a request for a single protocol or service:
Open the small, medium or large Validation Request card.
Select the validation from the Validation dropdown list.
To create and run a request for more than one protocol and/or service:
Open the large Validation Request card.
Click the names of the protocols and services you want to validate.
We selected BGP and EVPN in this example.
Click Run Now to start the validation.
The associated on-demand validation result cards (one per protocol or service selected) are opened on your current workbench. Refer to View On-demand Validation Results.
Create a New Scheduled Validation Request
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.
To create and run a new scheduled validation:
Open the large Validation Request card.
Select the protocols and/or 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 (2).
Modify an Existing Scheduled Validation Request
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 large Validation Request card.
Select the validation from the Validation dropdown list.
Edit the schedule or validation types.
Click Update.
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.
View On-demand Validation Results
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. When multiple network protocols or services are included in a validation, a validation result card is opened for each protocol and service.

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.

Monitor Network Inventory
With NetQ, a network administrator can monitor both the switch hardware and its operating system for misconfigurations or misbehaving services. The Devices Inventory card workflow provides a view into the switches and hosts installed in your network and their various hardware and software components. The workflow contains a small card with a count of each device type in your network, a medium card displaying the operating systems running on each set of devices, large cards with component information statistics, and full-screen cards displaying tables with attributes of all switches and all hosts in your network.
The Devices Inventory card workflow helps answer questions such as:
What switches do I have in the network?
What is the distribution of ASICs across my network?
Do all switches have valid licenses?
Are NetQ agents running on all of my switches?
For monitoring inventory and performance on a switch-by-switch basis, refer to Monitor Switches.

View Service Status Summary
A summary of the BGP service is available from the Network Services card workflow, including the number of nodes running the service, the number of BGP-related alarms, and a distribution of those alarms.
To view the summary, open the small BGP Service card.
For more detail, select a different size BGP Service card.
View the Distribution of Sessions and Alarms
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.
To view these distributions, open the medium BGP Service card.
If a visual correlation is apparent, you can dig a little deeper with the large BGP Service card tabs.
View Devices with the Most BGP Sessions
You can view the load from BGP on your switches and hosts using the large Network Services card. This data enables you to see which switches are handling the most BGP 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 BGP sessions:
Open the large BGP Service 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.
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.
To view switches with the most unestablished BGP sessions:
Open the large BGP Service 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 Switches.
Click Show All Sessions to investigate all BGP sessions with events in the full screen card.
View Devices with the Most BGP-related Alarms
Switches or hosts experiencing a large number of BGP alarms may indicate a configuration or performance issue that needs further investigation. You can view the devices sorted by the number of BGP alarms and then use the Switches card workflow or the Alarms card workflow to gather more information about possible causes for the alarms.
To view switches with the most BGP alarms:
Open the large BGP Service 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.

Monitor a Single BGP Session
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 BGP Service, click the All Sessions tab, select the desired session, then click (Open Cards).
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.

A summary of the LLDP service is available from the Network Services card workflow, including the number of nodes running the service, the number of LLDP-related alarms, and a distribution of those alarms.
To view the summary, open the small LLDP Service card.
In this example, there are no LLDP alarms present on the network of 14 devices.
For more detail, select a different size LLDP Network Services card.
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, as it gives you insight into nodes that might be misconfigured or experiencing communication issues. Additionally, if there are a large number of alarms, it is worth investigating either the service or particular devices.
To view the distribution, open the medium LLDP Service 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.
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 LLDP Service 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 missing the neighbor (peer) device.
View Devices with the Most LLDP Sessions
You can view the load from LLDP on your switches using the large LLDP Service card. 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 LLDP Service 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.
View Devices with the Most Unestablished LLDP Sessions
You can identify switches that are experiencing difficulties establishing LLDP sessions; both currently and in the past.
To view switches with the most unestablished LLDP sessions:
Open the large LLDP Service card.

To access the single session cards, you must open the full screen LLDP Service card, click the All Sessions tab, select the desired session, then click (Open Cards).
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.

Optionally, open the small LLDP Session card.
View LLDP Session Neighbor State Changes
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 full screen LLDP Service card.
Double-click on a session. The full screen card closes automatically.
Locate the medium 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 name, and the peer name and interface name.
To view the neighbor availability for a given LLDP session on the large LLDP Session card, open that card.
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. This can be useful when you are troubleshooting potential causes for alarms or sessions losing their connections.
To view the configuration file changes:

To view the summary, open the small MLAG Service card.
For more detail, select a different size MLAG Service card.
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 a MLAG session.
To view these distributions, open the medium MLAG Service card.
If a visual correlation is apparent, you can dig a little deeper with the large MLAG Service card tabs.
View Devices with the Most CLAG Sessions
You can view the load from MLAG on your switches using the large MLAG Service 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 MLAG Service 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 access the single session cards, you must open the full screen MLAG Service, click the All Sessions tab, select the desired session, then click (Open Cards).
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 from the MLAG Session card workflow, showing the node and its peer and current status.
To view the summary:
Open the full screen MLAG Service card.
Select a session from the listing to view.
Close the full screen card to view the medium 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. In the right example, we see that the leaf03 switch plays the primary role in this session with leaf04.
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:
Open the full screen MLAG Service card.
Select a session from the listing to view.
Close the full screen card to view the medium MLAG Session card.
In this example, the peer switch has been alive for the entire 24-hour period.

Monitor the OSPF Service
The Cumulus NetQ UI enables operators to view the health of the OSPF service on a network-wide 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. They are described separately here.
Monitor the OSPF Service (All Sessions)
With NetQ, you can monitor the number of nodes running the OSPF service, view switches with the most full and unestablished OSPF sessions, and view alarms triggered by the OSPF service. For an overview 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.

To view the summary, open the small OSPF Service card.
For more detail, select a different size OSPF Service card.
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 OSPF Service card.
You can dig a little deeper with the large OSPF Service card tabs.
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 OSPF Service 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.
View Devices with the Most Unestablished OSPF Sessions
You can identify switches and hosts that are experiencing difficulties establishing OSPF sessions; both currently and in the past.
To view switches with the most unestablished OSPF sessions:

For an overview 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.
To access the single session cards, you must open the full screen OSPF Service, click the All Sessions tab, select the desired session, then click (Open Cards).
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.

To view the state transitions for a given OSPF session on the large OSPF Session card, follow the same steps to open the medium OSPF Session card and then switch to the large card.
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. This can be useful when you are troubleshooting potential causes for alarms or sessions losing their connections.
To view the configuration file changes:
Open the large OSPF Session card.
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 a change to highlight, so it shows the same file on both sides.
View All OSPF Session Details
You can view all stored attributes of all of the OSPF sessions associated with the two devices on this card.
To view all session details, open the full screen OSPF Session card, and click the All OSPF Sessions tab.

Monitor 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 adhoc fashion and by defining connectivity checks to occur on a scheduled basis. There are three card workflows which enable you to view connectivity, the Trace Request, On-demand Trace Results, and Scheduled Trace Results.
Create a Trace Request
Two types of connectivity checks can be run-an immediate (on-demand) trace and a scheduled trace. The Trace Request card workflow is used to configure and run both of these trace types.

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. It you cannot find a path through a layer 3 path, you might also try checking connectivity through a layer 2 path.
To create a layer 3 trace request:
Open the medium Trace Request card.
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 server02 and ending it at 10.1.3.103.
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.
Click Run Now. A corresponding Trace Results card is opened on your workbench. Refer to View Layer 3 Trace Results for details.
Create a Layer 3 Trace Through a Given VRF
If you want to guide a trace through a particular VRF interface, you can do so using the large New Trace Request card.
To create the trace request:
Open the large Trace Request card.
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 interface you want to use.
In this example, we are starting our trace at leaf01 and ending it at 10.1.3.103 using VRF vrf1.
Click Run Now. A corresponding Trace Results card is opened on your workbench. Refer to View Layer 3 Trace Results for details.
Create a Layer 2 Trace

In this example, we are starting our trace at leaf01 and ending it at 00:03:00:33:33:01 using VLAN 13.
Click Run Now. A corresponding Trace Results card is opened on your workbench. Refer to View Layer 2 Trace Results for details.
Create a Trace to Run on a Regular Basis (Scheduled Trace)
There may be paths through your network that you consider critical to your everyday or particularly important operations. In that case, 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. Scheduling a trace request can be performed from the large Trace Request card.
To schedule a trace:
Open the large Trace Request card.
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 (layer 2) or IP address (layer 3) of the device where you want to end the trace.
Optionally, enter a VLAN ID (layer 2) or VRF interface (layer 3).
Select a timeframe under Schedule to specify how often you want to run the trace.

View Layer 2 Trace Results
When you start the trace, 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 the job is completed, the results are displayed.
In this example, we see that the trace was successful. Four paths were found between the devices, each with four hops and with an overall MTU of 1500. If there was a difference between the minimum and maximum number of hops or other failures, viewing the results on the large card would provide additional information.
In our example, we can verify that every path option had four hops since the distribution chart only shows one hop count and the table indicates each path had a value of four hops. Similarly, you can view the MTU data. If there had been any warnings, the count would have been visible in the table.
View Layer 3 Trace Results
When you start the trace, 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. Six paths were found between the devices, each with five hops and with an overall MTU of 1500. If there was a difference between the minimum and maximum number of hops or other failures, viewing the results on the large card would provide additional information.
In our example, 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. If there had been any warnings, the count would have been visible in the table.

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 full screen Trace Request card to view all scheduled traces that have been run.
Select the scheduled trace you want to view results for by clicking in the first column of the result and clicking the check box.
On the Edit Menu that appears at the bottom of the window, click (Open Cards). 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.
Monitor Devices
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 network-wide. The topics contained in this section describe monitoring tasks that apply to particular device types. For network-wide monitoring refer to Monitor Network Performance.
Monitor Switches
With the NetQ UI, you can monitor individual switches separately from the network. You are able to view the status of services they are running, health of its various components, and connectivity performance. Being able to monitor switch component inventory aids in upgrade, compliance, and other planning tasks. Viewing individual switch health helps isolate performance issues.
Viewing detail about a particular switch is essential when troubleshooting performance issues. With NetQ you can view the overall performance and drill down to view attributes of the switch, interface performance and the events associated with a switch. This is accomplished through the Switches card.

View the Overall Health of a Switch
When you want to monitor the health of a particular switch, open the 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 and summary performance score and trend.
To view the summary:
Click , and select Device|Switches. A dialog box opens.
Begin typing the hostname of the device you are interested in. Select it from the suggested matches when it appears.
Select small to open the small size card.
Click Add, or Cancel to exit the process.
In this example, we see that the leaf01 switch has had very few alarms overall, but the number is trending upward, with a total count of 24 alarms currently.
View Health Performance 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, 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
scheduled traces
interface performance
platform performance
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 Charts or Alarms at the top of the card.
View Attributes of a Switch
For a quick look at the key attributes of a particular switch, open the large Switch card. Attributes are displayed as the default tab.
In this example, the items of interest might be the five interfaces that are down and what version of OS and NetQ Agent the switch is running.
View Current Resource Utilization for a Switch
The NetQ GUI enables you to easily view the performance of various hardware components and the network tables. This enables you to determine whether a switch is reaching its maximum load and compare its performance with other switches.
To view the resource utilization on a particular switch:
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 a different Switch card for a comparable switch. Is the performance similar?
View Interface Statistics for a Switch
If you suspect that a particular switch is having performance problems, you might want to view the status of its interfaces. The statistics can also provide insight into interfaces that are more heavily loaded than others.
To view interface statistics:
Click .
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.
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 IP addresses, MAC addresses, and interfaces on the switch.
Open another switch card to compare performance on a similar interface.
View All Addresses for a Switch
It can be useful to view all of the configured addresses that this switch is using. You can view all IP addresses or all MAC addresses using the full screen Switch card.
To view all IP addresses:
Open the full screen Switch card. Click IP addresses.
By default All IP addresses are selected. Click IPv6 or IPv4 above the table to view only those IP addresses.
Review the addresses for any anomalies, to obtain prefix information, determine if it is an IPv4 or IPv6 address, and so forth.
To return to the workbench, click in the top right corner.
To view all MAC addresses:
Open the full screen Switch card and click MAC Addresses.
Review the addresses for any anomalies, to see the associated egress port, associated VLANs, and so forth.
To return to the workbench, click in the top right corner.
View All Interfaces on a Switch
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.
View All Software Packages on a Switch
You can view all of the software installed on a given switch to quickly validate versions and total software installed.
To view all software packages:
Open the full-screen Switch card and click Installed Packages.
Look for packages of interest and their version and status. Sort by a particular parameter by clicking .
Optionally, export the list by selecting all or specific packages, then clicking .
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. For details about when a rebalance is recommended, refer to When to Rebalance BTRFS Partitions.
To view the disk state:
Open the full-screen Switch card for a switch of interest:
Type the switch name in the Search box, then use the card size picker to open the full-screen card, or
Click (Switches) and 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.
View SSD Utilization
For NetQ servers and 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 utiilization 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.

Opens full screen card displaying all components for all switches
The full screen Switch Inventory card provides tabs for all components, ASIC, platform, CPU, memory, disk, and OS components.
There are a multitude of ways to view and analyze the available data within this workflow. A few examples are provided here.
View a Summary of Communication Status for All Switches
A communication status summary for all of your switches across the network is available from the small Switch Inventory card.
In this example, we see all 13 switches have been heard from recently (they are fresh).
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:
Open the medium or large Switch Inventory card. Each component has a chart showing the distribution.
OR
Hover over a segment of the chart to view the name, version, model or vendor and the number of switches that have been deployed. You can also see the percentage of all switches this total represents. On the large Switch Inventory card, hovering also highlights the related components for the selected component. This is shown in blue here.
Point to additional segments on that component or other components to view their detail.
Scroll down to view additional components.
View the Number of Switches with Invalid or Missing Licenses
It is important to know when you have switches that have invalid or missing Cumulus Linux licenses, as not all of the features are operational without a valid license. Simply open the medium or large Switch Inventory card, and hover over the License chart to see the count.
To view which vendors and platforms have bad or missing licenses, open the large Switch Inventory card, and click to open the Platform tab. Hover over the License State bar chart to highlight the vendor and platforms with the various states.
To view which switches have invalid or missing licenses, either:
Hover over the large Switch Inventory card and click to open the Platform tab. Above the Licenses State or the Vendor chart, click Show All.
Open the full screen Switch Inventory card. Then sort the All Switches tab data table by the License State column to locate the switches with bad or missing licenses.
View the Most Commonly Deployed ASIC
It can be useful to know the quantity and ratio of many components deployed in your network to determine the scope of upgrade tasks, balance vendor reliance, or for detailed troubleshooting. You can view the most commonly deployed components in generally the same way. Some components have additional details contained in large card tabs.
To view the most commonly deployed ASIC, for example:
Open the medium or large Switch Inventory card.
Hover over the largest segment in the ASIC chart. The tooltip that appears shows you the number of switches with the given ASIC and the percentage of your entire switch population with this ASIC.
Click on any other component in a similar fashion to see the most common type of that component.
If you opened the medium Switch Inventory card, switch to the large card.
Hover over the card, and click to open the ASIC tab. Here you can more easily view the various vendors and platforms based on the ASIC deployed.
Hover over the Vendor pie chart to highlight which platforms are supported by the vendor and vice versa; hover over the Model pie chart to see which vendor supports that platform. Moving your cursor off of the charts removes the highlight.
Click on a segment of the Vendor pie chart to drill down and see only that Vendor and its supported models. A filter tag is placed at the top of the charts.
To return to the complete view of vendors and platforms, click on the filter tag.
View the Number of Switches with a Particular NetQ Agent
It is recommended that when you upgrade NetQ that you also upgrade the NetQ Agents. You can determine if you have covered all of your agents using the medium or large Switch Inventory card. To view the NetQ Agent distribution by version:
Open the medium Switch Inventory card.
View the number in the Unique column next to Agent.
If the number is greater than one, you have multiple NetQ Agent versions deployed.
If you have multiple versions, hover over the Agent chart to view the count of switches using each version.
For more detail, switch to the large Switch Inventory card.
Hover over the card and click to open the Software tab.
Hover over the chart on the right to view the number of switches using the various versions of the NetQ Agent.
Hover over the Operating System chart to see which NetQ Agent versions are being run on each OS.
Click either chart to focus on a particular OS or agent version.
To return to the full view, click in the filter tag.
Filter the data on the card by switches that are having trouble communicating, by selecting Rotten Switches from the dropdown above the charts.
View a List of All Data for a Specific Component
When the small, medium and large Switch Inventory cards do not provide either enough information or are not organized in a fashion that provides the information you need, open the full screen Switch Inventory card. Select the component tab of interest and filter and sort as desired. Export the data to a third-party tool, by clicking .
Monitor Network Elements
In addition to network performance monitoring, the Cumulus NetQ UI provides a view into the current status and configuration of the network elements in a tabular, network-wide 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.

View What Just Happened
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.
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 disable the NetQ Agent 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).
View What Just Happened Metrics
The What Just Happened 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.

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 network-wide. 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.
This guide is intended for network administrators who are responsible
for monitoring and troubleshooting the network in their data center
environment. NetQ 2.x offers the ability to easily monitor and manage
your data center network infrastructure and operational health. This
guide provides instructions and information about monitoring individual
components of the network, the network as a whole, and the NetQ software
itself using the NetQ command line interface (CLI). If you prefer to use
a graphical interface, refer to the Cumulus NetQ UI User Guide.
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
The switches must be running the Cumulus Linux operating system (OS), NetQ Platform software, and the NetQ Agent. The hosts must be running CentOS, RHEL, or Ubuntu OS and the NetQ Agent. 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
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 two optional parameters, vrf and around, that can be used with a BGP check.
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.
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:
agents: NetQ Agents status on switches and hosts
bgp: BGP status across the network fabric
cl-btrfs-info: BTRFS file system data for monitored Cumulus Linux switches
cl-manifest: Information about the versions of Cumulus Linux available on monitored switches
cl-pkg-info: Information about software packages installed on monitored switches
cl-resource: ACL and forwarding information
cl-ssd-util: SSD utilization information
clag: CLAG/MLAG status
ethtool-stats: Interface statistics
events: Display changes over time
evpn: EVPN status
interface-stats: Interface statistics
interface-utilization: Interface statistics plus utilization
interfaces: network interface port status
inventory: hardware component information
ip: IPv4 status
ipv6: IPv6 status
job-status: status of jobs running on the OPTA
kubernetes: Kubernetes cluster, daemon, pod, node, service and replication status
lldp: LLDP status
mac-history: Historical information for a MAC address
macs: MAC table or address information
mlag: MLAG status (an alias for CLAG)
notification: Slack or PagerDuty notification configurations
ntp: NTP status
opta-health: Display health of apps on the OPTA
opta-platform: NetQ Appliance version information and uptime
ospf: OSPF status
recommended-pkg-version: Current host information to be considered
resource-util: Display usage of memory, CPU and disk resources
sensors: Temperature/Fan/PSU sensor status
services: System services status
tca: Threshold crossing alerts
trace: Control plane trace path across fabric
unit-tests: Show list of unit tests for netq check
validation: Schedule a validation check
vlan: VLAN status
vxlan: VXLAN data path status
wjh-drop: drop information from Mellanox What Just Happened
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, add and remove Kubernetes container monitoring, add or remove sensors, debug the agent, and add or remove FRR (FRRouting).
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 Platform or NetQ
Appliance.
cumulus@switch~:$ netq config add cli server 10.1.3.101
This example shows how to enable the CLI on a NetQ Cloud Appliance with a single premise.
netq config add cli server api.netq.cumulusnetworks.com access-key <user-access-key> secret-key <user-secret-key> 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:
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.
A number of commands have changed in this release to accommodate the addition of new options or to simplify their syntax. Additionally, new commands have been added and others have been removed. A summary of those changes is provided here.
New Commands
The following table summarizes the new commands available with this release. They include lifecycle management (LCM) and modular agent commands.

Configure Lifecycle Management
This topic for network administrators only.
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 introduces Lifecycle Management (LCM) to the NetQ CLI, which supports Cumulus Linux image, switch, and credential management.
Switch access credentials are needed for upgrading Cumulus Linux on the switches. You can choose between basic authentication (username and password) and SSH key-based authentication. These credentials apply to all switches.
To configure basic authentication for the cumulus user with the password CumulusLinux!, run:
To configure authentication using a public SSH key, run:
netq lcm add credentials ssh-key PUBLIC_SSH_KEY
View Credentials
A switch can have just one set of credentials. To see the credentials, run netq lcm show credentials.
If an SSH key is used for the credentials, the public key is displayed in the command output:
cumulus@switch:~$ netq lcm show credentials
Type SSH Key Username Password Last Changed
---------------- -------------- ---------------- ---------------- -------------------------
SSH MY-SSH-KEY Tue Apr 28 19:08:52 2020
If a username and passord is used for the credentials, the username is displayed in the command output but the password is masked:
cumulus@leaf01:mgmt-vrf:~$ netq lcm show credentials
Type SSH Key Username Password Last Changed
---------------- -------------- ---------------- ---------------- -------------------------
BASIC cumulus ************** Tue Apr 28 19:10:27 2020
Remove Credentials
To remove the credentials, run netq lcm del credentials.
Configure Switch Roles
Four pre-defined switch roles are available. Their names are based on Clos architecture:
Superspine
Spine
Leaf
Exit
Switch roles are used to:
Identify switch dependencies and determine the order in which switches are upgraded.
Determine when to stop if an upgrade fails.
For more information about managing switch roles, see Role Management.
To configure one or more switches for a given role, run netq lcm add role command. For example, to configure leaf01 through leaf04 in the leaf role, run:
netq lcm add role leaf switches leaf01,leaf02,leaf03,leaf04
Show Switch Roles
To see the roles of the switches in the fabric, run netq lcm show switches. You can filter the list by a particular version by running netq lcm show switches version X.Y.Z.
After installing NetQ 3.0, there are no Cumulus Linux images in the LCM repository. You can upload Cumulus Linux binary images to a local LCM repository for use with installation and upgrade of your switches.
For more information about Cumulus Linux images and LCM, read Image Management.
Download the version of Cumulus Linux you plan to use to upgrade the switches from the MyMellanox downloads page.
Upload the image onto an accessible part of your network. The following example uses the Cumulus Linux 3.7.12 disk image, named cumulus-linux-3.7.12-bcm-amd64.bin.
LCM provides the ability to upgrade Cumulus Linux on switches on your network through NetQ. Once the image is uploaded and the switch credentials are configured, you can upgrade the operating system. To do you, you need:
A Cumulus Linux license file accessible over the network.
A Cumulus Linux install image accessible over the network.
The ID for the Cumulus Linux image.
The names of the switches you plan to upgrade.
To upgrade one or more switches:
Get the Cumulus Linux install image ID. Determine the image ID intended to upgrade the switches and copy it.
cumulus@switch:~$ netq lcm show images

Perform the upgrade:
cumulus@switch:~$ netq lcm upgrade name upgrade-3712 image-id cl_image_69ce56d15b7958de5bb8371e9c4bf2fc9131da9a57b13853e2a60ca109238b22 license LICENSE hostnames spine01,spine02 order spine
You can assign an order for which switches to upgrade based on the switch roles defined above. For example, to upgrade the spines before the leafs, add the order ROLE1,ROLE2 option to the command:
cumulus@switch:~$ netq lcm upgrade name upgrade-3712 image-id cl_image_69ce56d15b7958de5bb8371e9c4bf2fc9131da9a57b13853e2a60ca109238b22 license LICENSE hostnames spine01,spine02,leaf01,leaf02 order spine,leaf
If the switches have not been assigned a role, then do not use the order option. So in this example, if switches spine01 and spine02 have not been assigned the spine role, then do not specify the order spine option.
You can also decide to run LCM before and after the upgrade by adding the run-before-after option to the command:
cumulus@switch:~$ netq lcm upgrade name upgrade-3712 image-id cl_image_69ce56d15b7958de5bb8371e9c4bf2fc9131da9a57b13853e2a60ca109238b22 license LICENSE hostnames spine01,spine02,leaf01,leaf02 order spine,leaf run-before-after
Running an Upgrade Job Again
Every upgrade job requires a unique name. If the upgrade job fails, you need to provide a new name for the job in order to run the upgrade job again. You can get the history of all previous upgrade jobs to ensure that the new upgrade job does not have a duplicate name.
To see a history of previous upgrades that have been run, run netq lcm show upgrade-jobs:
cumulus@switch:~$ netq lcm show upgrade-jobs

Monitor Overall Network Health
NetQ provides the information you need to monitor the health of your network fabric, devices, and interfaces. You are able to easily validate the operation and view the configuration across the entire network from switches to hosts to containers. For example, you can monitor the operation of routing protocols and virtual network configurations, the status of NetQ Agents and hardware components, and the operation and efficiency of interfaces. 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.
Validate Network Health
NetQ check commands 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 and display the results for your assessment. They can be run from any node in the network.
Validate the Network Fabric
You can validate the following network fabric elements:
cumulus@switch:~$ netq check
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
Validation Commands
The validation commands have been changed in this release:
You can view more detail about the validation tests that are run with each command
You can filter these tests to run only those tests of interest
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.
Each of the check commands provides a starting point for troubleshooting configuration and connectivity issues within your network in real time.
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.
You can view only the summary of the validation results by running the netq check commands with summary option; for example, netq check agents summary or netq check evpn summary. This summary displays such data as the total number of nodes checked, how many failed a test, total number of sessions checked, how many of these that failed, and so forth.
You can view more information about the individual tests that are run as part of the validation, including individual tests for agents.
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.
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. By default, all tests are run. The value of <protocol-number-range-list> 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.
Output from the netq check commands are color-coded; green for successful results and red for failures, warnings, and errors. Use the netq config add color command to enable the use of color.
What the NetQ Validation System Checks
Each of the netq check commands perform a set of validation tests appropriate to the protocol or element being validated.
To view the list of tests run for a given protocol or service, use either netq show unit-tests <protocol/service> or perform a tab completion on netq check <protocol/service> [include|exclude].
This section describes these tests.
NetQ Agent Validation Tests
The netq check agents command looks for an agent status of Rotten for each node in the network. A Fresh status indicates the Agent is running as expected.

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.

Total nodes : 6
Rotten nodes : 0
Failed nodes : 0
Warning nodes : 0
Vlan Consistency Test : passed,
BUM replication Test : passed,
Both asymmetric and symmetric VXLAN configurations are validated with this command.
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>:

Monitor Switch Hardware
With NetQ, a network administrator can monitor the key components of switch an NetQ Appliance hardware, including the motherboard, ASIC, microprocessor,
disk, memory, fan and power supply information. You can also monitor temperature and SSD utilization information. With this data, NetQ helps you answer questions such as:
What switches do I have in the network?
What hardware is installed on my switches?
How many transmit and receive packets have been dropped?
How healthy are the fans and power supply?
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.
The NetQ CLI provides a number of netq show commands to monitor switches. The syntax of these commands is:
netq [<hostname>] show inventory brief [opta] [json]
netq [<hostname>] show inventory asic [vendor <asic-vendor>|model <asic-model>|model-id <asic-model-id>] [opta] [json]
netq [<hostname>] show inventory board [vendor <board-vendor>|model <board-model>] [opta] [json]
netq [<hostname>] show inventory cpu [arch <cpu-arch>] [opta] [json]

netq [<hostname>] show interface-utilization [<text-port>] [tx|rx] [around <text-time>] [json]
netq [<hostname>] show resource-util [cpu | memory] [around <text-time>] [json]
netq [<hostname>] show resource-util disk [<text-diskname>] [around <text-time>] [json]
netq [<hostname>] show cl-ssd-util [around <text-time>] [json]
netq [<hostname>] show cl-btrfs-info [around <text-time>] [json]
netq [<hostname>] show events [level info|level error|level warning|level critical|level debug] [type interfaces-physical|type sensors|type btrfsinfo] [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.
The keyword values for the vendor, model, model-id, arch,
name, transport, type, version, psu, temp, and fan
keywords are specific to your deployment. For example, if you have
devices with CPU architectures of only one type, say Intel x86, then
that is the only option available for the cpu-arch keyword value. If
you have multiple CPU architectures, say you also have ARMv7, then that
would also be an option for you.
View a Summary of Your Network Inventory
While the detail can be very helpful, sometimes a simple overview of the
hardware inventory is better. This example shows the basic hardware
information for all devices.
You can view the vendor, model, model identifier, core bandwidth
capability, and ports of the ASIC installed on your switch motherboard.
This example shows all of these for all devices.

View SSD Utilization
For NetQ servers and 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.
Use the netq show cl-ssd-util command to view the SSD information.
This example shows the utilization for spine02 which has this type of SSD.
cumulus@switch:~$ netq spine02 show cl-ssd-util

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. View this information for all devices with this type of SSD by removing the hostname option, or add the around option to view this information around a particular time.
View Disk Storage Utilization 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. Refer to When to Rebalance BTRFS Partitions for details about the rules used to recommend a rebalance operation.
To view the disk utilization and whether a rebalance is recommended, use the netq show cl-btrfs-util command as follows:
cumulus@switch:~$ netq show cl-btrfs-info

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 hostname option to view the information for a given device, or use the around option to view the information for a particular time.
Monitor Switch Software
With NetQ, a network administrator can monitor the switch software components for misconfigurations. NetQ helps answer questions such as:
What software is installed on my switches?
Are all switches licensed correctly?
What is the ACL and forwarding resources usage?
Do all switches have NetQ Agents running?
The NetQ CLI provides the netq show inventory, netq show cl-<software-item>, and netq show events commands to monitor switches.
The syntax for these commands is:
netq [<hostname>] show agents
netq [<hostname>] show inventory brief [json]
netq [<hostname>] show inventory license [cumulus] [status ok|status missing] [around <text-time>] [json]
netq [<hostname>] show inventory os [version <os-version>|name <os-name>] [json]
netq [<hostname>] show cl-manifest [json]
netq [<hostname>] show cl-pkg-info [<text-package-name>] [around <text-time>] [json]
netq [<hostname>] show recommended-pkg-version [release-id <text-release-id>] [package-name <text-package-name>] [json]
netq [<hostname>] show cl-resource acl [ingress | egress] [around <text-time>] [json]
netq [<hostname>] show cl-resource forwarding [around <text-time>] [json]
netq [<hostname>] show events [level info|level error|level warning|level critical|level debug] [type license|type os] [between <text-time> and <text-endtime>] [json]
The values for the name option are specific to your
deployment. For example, if you have devices with only one type of OS,
say Cumulus Linux, then that is the only option available for the
os-name option value. If you have multiple OSs running, say you also
have Ubuntu, then that would also be an option for you.
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 OS Information for a Switch
You can view the name and version of the OS on a switch, and when it was
last modified. This example shows the OS information for all devices.
You can filter the results of the command to view only devices with a
particular operating system or version. This can be especially helpful
when you suspect that a particular device has not been upgraded as
expected. This example shows all devices with the Cumulus Linux version
3.7.5 installed.
This example shows changes that have been made to the OS on all devices
between 16 and 21 days ago. Remember to use measurement units on the
time values.

View Summary of Operating System on a Switch
As with the hardware information, you can view a summary of the software
information using the brief keyword. Specify a hostname to view the
summary for a specific device.
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.
This example shows the Cumulus Linux OS versions supported for the leaf01 switch, using the vx ASIC vendor (virtual, so simulated) and x86_64 CPU architecture.
If you are having an issue with a particular switch, you may want to verify what software is installed and whether it needs updating. Use the netq show cl-pkg-info command to view the current package information.
This example shows all installed software packages for spine01.

Remove the hostname option to view the information for all switches. 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.
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. Additionally, you can determine if a software package is missing. Use the netq show recommended-pkg-version command to display a list of recommended packages to install/upgrade on one or all devices.
This example shows that the leaf12 switch which is running Cumulus Linux 3.7.1 needs to update the switchd software.

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

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.

Monitor Physical Layer Components
With NetQ, a network administrator can monitor OSI Layer 1 physical
components on network devices, including interfaces, ports, links, and
peers. NetQ provides the ability to:
Manage physical inventory: view the performance and status of various components of a switch or host server
Validate configurations: verify the configuration of network peers and ports
It helps answer questions such as:
Are any individual or bonded links down?
Are any links flapping?
Is there a link mismatch anywhere in my network?
Which interface ports are empty?
Which transceivers are installed?
What is the peer for a given port?
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.
Monitor Physical Layer Inventory
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 changes in your physical layer, and when they occurred
The netq show interfaces physical command is used to obtain the
information from the devices. Its syntax is:
netq [<hostname>] show interfaces physical [<physical-port>] [empty|plugged] [peer] [vendor <module-vendor>|model <module-model>|module] [around <text-time>] [json]
netq [<hostname>] show events [level info|level error|level warning|level critical|level debug] type interfaces-physical [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 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. This example shows
cable information and status for all interface ports on all devices.

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

View Interface Statistics
The ethtool command provides a wealth of statistics about network interfaces. The netq show ethtool-stats command returns statistics about a given node and interface, including frame errors, ACL drops, buffer drops and more.
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 illustrates the statistics for switch port swp1 on a specific switch in the network.
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.

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.
Example: 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.
You can also determine whether a link is flapping using the netq check interfaces command. If a link is flapping, NetQ indicates this in a
message:
cumulus@switch:~$ netq check interfaces
Checked Nodes: 18, Failed Nodes: 8
Checked Ports: 741, Failed Ports: 1, Unverified Ports: 414

Monitor Data Link Layer Devices and Protocols
With NetQ, a network administrator 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. NetQ provides the ability to:
Monitor and validate device and protocol configurations
View available communication paths between devices
It helps answer questions such as:
Is a VLAN misconfigured?
Is there an MTU mismatch in my network?
Is MLAG configured correctly?
Is there an STP loop?
Can device A reach device B using MAC addresses?
Monitor LLDP Operation
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 timeframe. NetQ enables
you to view LLDP information for your devices using the netq show lldp
command. The syntax for this command is:
netq [<hostname>] show lldp [<remote-physical-interface>] [around <text-time>] [json]
netq [<hostname>] show events [level info|level error|level warning|level critical|level debug] type lldp [between <text-time> and <text-endtime>] [json]
View LLDP Information for All Devices
This example shows the interface and peer information that is advertised for each device.

Monitor Interface Health
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 network-wide.

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 network-wide.
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 VLAN Configurations
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. With NetQ, 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 enable you to view VLAN information associated
with interfaces and MAC addresses. The syntax for these commands is:
netq [<hostname>] 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 [<hostname>] show events [level info | level error | level warning | level critical | level debug] type vlan [between <text-time> and <text-endtime>] [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 vlan [<1-4096>] [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 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 VLAN13.

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 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 MAC address on a particular VLAN, using the vlan 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 mac-history <mac> [vlan <1-4096>] [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 a MAC Address. The caret (^) notation indicates no change in this value from the row above.

Monitor MLAG Configurations
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.
MLAG or CLAG?
The Cumulus Linux implementation of MLAG is referred to by other vendors
as CLAG, MC-LAG or VPC. You will even see references to CLAG in Cumulus
Linux and Cumulus NetQ, including the management daemon, named clagd, and other options
in the code, such as clag-id, which exist for historical purposes. The
Cumulus Linux implementation is truly a multi-chassis link aggregation
protocol, so we call it MLAG.
For instructions on configuring MLAG, refer to the MLAG topic in the Cumulus Linux User Guide.
With NetQ, you can view the configuration and operation of devices using
MLAG using the netq show clag command. You can view the current
configuration and the configuration at a prior point in time, as well as
view any changes that have been made within a timeframe. The syntax for
the show command is:
netq [<hostname>] show clag [around <text-time>] [json]
netq [<hostname>] show events [level info|level error|level warning|level critical|level debug] type clag [between <text-time> and <text-endtime>] [json]
View MLAG Configuration and Status for all Devices
This example shows the configuration and status of MLAG for all devices.
In this case, three MLAG pairs are seen between leaf11 and leaf12 (which
happens to be down), edge01(P) and edge02, and leaf21(P) and leaf22.

You can go back in time to see when this first MLAG pair went down.
These results indicate that the pair became disconnected some time in
the last five minutes.

This example shows that leaf22 is up and MLAG properly configured with a
peer connection to leaf21 through 8 bonds, all of which are dual bonded.

When you’re directly on the switch, you can run clagctl to get the
state:
It is important that the switches and hosts remain in time
synchronization with the NetQ Platform 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 command 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]
This example shows the time synchronization status for all devices in
the network.
This example shows all devices in the network that are out of time
synchronization, and consequently might need to be investigated.

Monitor Spanning Tree Protocol Configuration
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 have VLANs configured, you can view the available paths between two devices on the VLAN currently and at a time in the past using their MAC addresses . You can 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.
To view the paths:
Identify the MAC address and VLAN ID for the destination device
Identify the IP address or hostname for the source device
Use the netq trace command to see the available paths between
those devices.
The syntax requires the destination device address first, mac, and
then the source device address or hostname. Additionally, the vlan
keyword-value pair is required for layer 2 traces even though the syntax
indicates it is optional.
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.
View Paths between Two Switches with Pretty Output
This example shows the available paths between a top of rack switch,
tor-1, and a server, server11. The request is to go through VLAN
1001 from the VRF vrf1. The results include a summary of the trace,
including the total number of paths available, those with errors and
warnings, and the MTU of the paths. In this case, the results are
displayed in pseudo-graphical output.
View Paths between Two Switches with Drops Detected
If you have a Mellanox switch, the What Just Happened feature detects various drop statistics. These are visible in the results of trace requests. This example shows the available paths between a switch with IP address 6.0.2.66 and a switch with IP address 6.0.2.70, where drops have been detected on path 1.

Monitor Layer 2 Drops on Mellanox Switches
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.
When WJH capabilities are combined with Cumulus Linux 4.0.0 and NetQ 2.4.0, giving you 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.
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.
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 disable the NetQ Agent 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).

Monitor Network Layer Protocols
With NetQ, a network administrator can monitor OSI Layer 3 network
protocols running on Linux-based hosts, including IP (Internet
Protocol), BGP (Border Gateway Protocol) and OSPF (Open Shortest Path
First). NetQ provides the ability to:
Validate protocol configurations.
Validate layer 3 communication paths.
It helps answer questions such as:
Who are the IP neighbors for a switch?
How many IPv4 and IPv6 addresses am I using?
When did changes occur to my IP configuration?
Is BGP working as expected?
Is OSPF working as expected?
Can device A reach device B using IP addresses?
Monitor IP Configuration
NetQ enables you to view the current status and the status an earlier
point in time. From this information, you can:
Determine IP addresses of one or more interfaces.
Determine IP neighbors for one or more devices.
Determine IP routes owned by a device.
Identify changes to the 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]

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.

Monitor BGP Configuration
If you have BGP running on your switches and hosts, you can monitor its
operation using the NetQ CLI. For each device, you can view its
associated neighbors, ASN (autonomous system number), peer ASN, receive
IP or EVPN address prefixes, and VRF assignment. Additionally, you can:
View the information at an earlier point in time.
Filter against a particular device, ASN, or VRF assignment.
Validate it is operating correctly across the network.
The netq show bgp command is used to obtain the BGP configuration
information from the devices. The netq check bgp command is used to
validate the configuration. The syntax of these commands is:
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 BGP Configuration Information
NetQ enables you to view the BGP configuration of a single device or
across all of your devices at once. You can filter the results based on
an ASN, BGP session (IP address or interface name), or VRF assignment.
You can view the configuration in the past and view changes made to the
configuration within a given timeframe.
Example: View BGP Configuration Information Across Network
This example shows the BGP configuration across all of your switches. In
this scenario, BGP routing is configured between two spines and four
leafs. Each leaf switch has a unique ASN and the spine switches share an
ASN. The PfxRx column indicates that these devices have IPv4 address
prefixes. The second and third values in this column indicate IPv6 and
EVPN address prefixes when configured. This configuration was changed
just over one day ago.
Example: View BGP Configuration Information for a Given Device
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 65020 and each of the leafs have unique ASNs.
Example: View BGP Configuration Information for a Given ASN
This example shows the BGP configuration information for ASN of
655557. This ASN is associated with spine02 and so the results show
the BGP neighbors for that switch.
This example shows that BGP configuration changes were made about five
days ago on this network.

Validate BGP Operation
A single command enables you to validate that all configured route
peering is established across the network. The command checks for
duplicate router IDs and sessions that are in an unestablished state.
Either of these conditions trigger a configuration check failure. When a
failure is found, the reason is identified in the output along with the
time the issue occurred.
This example shows a check on the BGP operations that found no failed
sessions.
cumulus@switch:~$ netq check bgp
Total Nodes: 15, Failed Nodes: 0, Total Sessions: 16, Failed Sessions: 0
This example shows 24 failed BGP sessions with a variety of reasons.
cumulus@switch:~$ netq check bgp

Monitor OSPF Configuration
If you have OSPF running on your switches and hosts, you can monitor its
operation using the NetQ CLI. 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.
Filter against a particular device, interface, or area.
Validate it is operating correctly across the network.
The netq show ospf command is used to obtain the OSPF configuration information from the devices. The netq check ospf command is used to validate the configuration. The syntax of these commands is:
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 OSPF Configuration Information
NetQ enables you to view the OSPF configuration of a single device or
across all of your devices at once. You can filter the results based on
a device, interface, or area. You can view the configuration in the past
and view changes made to the configuration within a given timeframe.
Example: View OSPF Configuration Information Across the Network
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.

Validate OSPF Operation
A single command, netq check ospf, enables you to validate that all
configured route peering is established across the network. The command
checks for:
Router ID conflicts, such as duplicate IDs.
Links that are down, or have mismatched MTUs.
Mismatched session parameters (hello timer, dead timer, area IDs and network type).
When peer information is not available, the command verifies whether
OSPF is configured on the peer and if so, whether the service is
disabled, shutdown, or not functioning.
All of these conditions trigger a configuration check failure. When a
failure is found, the reason is identified in the output along with the
time the issue occurred.
This example shows a check on the OSPF operations that found no failed sessions.
cumulus@switch:~$ netq check ospf
Total Sessions: 16, Failed Sessions: 0
This example shows a check on the OSPF operations that found two failed
sessions. The results indicate the reason for the failure is a
mismatched MTU for two links.

View Paths between Devices
You can view the available paths between two devices on the network
currently and at a time in the past using their IPv4 or IPv6 addresses.
You can 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 the default when not specified, and 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 per hop and a set of rows per path.
To view the paths, first identify the addresses for the source and
destination devices using the netq show ip addresses command (see
syntax above), and then use the netq trace command to see the
available paths between those devices. The trace command syntax is:
The syntax requires the destination device address first, <ip>, and
then the source device address or hostname.
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.
View Paths between Two Switches with Pretty Output
This example first determines the IP addresses of the leaf01 and leaf03
switches, then shows the available paths between them. The results
include a summary of the trace, including the total number of paths
available, those with errors and warnings, and the MTU of the paths. In
this case, the results are displayed in pseudo-graphical output.

Monitor Virtual Network Overlays
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 Virtual Extensible LANs
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.

Consequently, if you looked for the VXLAN configuration and status for
last week, you would find either another configuration or no
configuration. This example shows that no VXLAN configuration was
present.
cumulus@switch:~$ netq show vxlan around 7d

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
single device.
You can filter the full device view to focus on a single VNI. This
example only shows the EVPN configuration and status for VNI 42.

Monitor Linux Hosts
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:
cumulus@switch:~$ netq server01 show lldp

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
------------------------ ---------------- -------------------- ---------------- --------------------

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.

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:

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.

View Kubernetes Cluster Configuration in the Past
You can use the "time machine" features of NetQ on a Kubernetes cluster, using 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.
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, and managing NetQ Agent logging are presented.
View NetQ Agent Status
To view the health of your NetQ Agents, use the netq show agents command:
netq [<hostname>] show agents [fresh | dead | rotten | opta] [around <text-time>] [json]
You can view the status for a given switch, host or NetQ server. You can also filter by the status as well as view the status at a time in the past.
This example shows how to prevent the agent from consuming no more than 40% of
CPU resources on a Cumulus Linux switch. This setting requires Cumulus Linux
versions 3.7.12 or later and 4.1.0 or later to be running on the switch.
netq config add agent cpu-limit 40
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.
Disable the NetQ Agent on a Node
You can temporarily disable NetQ Agent on a node. Disabling the agent
maintains the activity history in the NetQ database.
To disable NetQ Agent on a node, run the following command from the
node:
cumulus@switch:~$ netq config stop agent
Remove the NetQ Agent from a Node
You can decommission a NetQ Agent on a given node. You might need to do
this when you:
RMA the switch or host being monitored
Change the hostname of the switch or host being monitored
Move the switch or host being monitored from one data center to
another
Decommissioning the node removes the agent server settings from the
local configuration file.
To decommission a node from the NetQ database:
On the given node, stop and disable the NetQ Agent service.
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, run the
following command and restart the agent service:
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.
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. This way you can reduce agent CPU usage due to less frequent polling.
In addition, depending on the switch platform, some supported protocol commands may not be executed by the 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 the NetQ agent’s statistics every 5 minutes.
agent_util_stats: Collects the NetQ agent’s CPU and memory utilization every 30 seconds.
cl-support-json: Polls the switch every 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 2 minutes looking to see if the contents of any of these files changes. If a change occurs, 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, run:
You can disable any of these commands if they are not needed on your network. This can help reduce the compute resources the agent consumes. For example, if your network does not run OSPF, you can disable the two OSPF commands:
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:

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. In the example below, the NetQ Agent on server01 is rotten,
so you know where to start looking for problems:
cumulus@switch:$ netq check agents
Checked nodes: 12,
Rotten nodes: 1
netq@446c0319c06a:/$ netq show agents

Diagnose an Event after It Occurs
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 network-wide 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 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 like
PagerDuty or Slack or use netq show events 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.
For example, say you get an alert about a BGP session failure. You can
quickly run netq check bgp to determine what sessions failed:
cumulus@switch:~$ netq check bgp
Total Nodes: 25, Failed Nodes: 3, Total Sessions: 220 , Failed Sessions: 24,

You can run a trace from spine01 to leaf02, which has the IP address
10.1.20.252:
cumulus@switch:~$ netq trace 10.1.20.252 from spine01 around 5m
spine01 -- spine01:swp1 -- leaf01:vlan20
-- spine01:swp2 -- leaf02:vlan20
Then you can check what’s changed on the network to help you identify
the problem.
cumulus@switch:~$ netq show events type bgp

Use NetQ as a Time Machine
With NetQ, you can travel back to a specific point in time or a range of
times to help you isolate errors and issues.
For example, 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@leaf01:~$ netq check sensors around 12h
Total Nodes: 25, Failed Nodes: 0, Checked Sensors: 221, Failed Sensors: 0
Or you can specify a range of times using the between option. The
units of time you can specify are second (s), minutes (m), hours
(h) and days (d). Always specify the most recent time first, then
the more distant time. For example, to see the changes made to the
network between the past minute and 5 minutes ago, you’d run:
cumulus@switch:/$ netq show events between now and 48h

You can travel back in time 5 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
Detected Routing Loop. Node exit01 (now via Local Node exit01 and Ports swp6 <==> Remote Node/s spine01 and Ports swp3) visited twice.

spine02 -- spine02:swp3 -- exit01:swp6.4 -- exit01:swp3 -- exit01
-- spine02:swp7 -- spine02
Trace Paths in a VRF
The netq trace command works with VRFs as well:
cumulus@leaf01:~$ netq trace 10.1.20.252 from spine01 vrf default around 5m
spine01 -- spine01:swp1 -- leaf01:vlan20
-- spine01:swp2 -- leaf02:vlan20
Generate a Support File
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: 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

Similarly, checking the MLAG state with NetQ also confirms this:
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.

As an administrator, you must secure, configure, and manage your network hardware and software. Tasks associated with managing your physical hardware (switches) and virtual machines (VMs), Cumulus Linux and Cumulus NetQ software are described in this document. These responsibilities are grouped into two categories:
Application Management: manage access to and various application-wide settings for the Cumulus NetQ UI from a single location
Lifecycle Management: manage deployment and perform operational tasks for Cumulus Linux and Cumulus NetQ products from the NetQ UI or CLI
Application Management
As an administrator, you can manage access to and various application-wide settings for the Cumulus NetQ UI from a single location.
Individual users have the ability to set preferences specific to their
workspaces. This information is covered separately. Refer to
Set User Preferences.
NetQ Management Workbench
The NetQ Management workbench is accessed from the main menu. For the user(s) responsible for maintaining the application, this is a good place to start each day.
To open the workbench, click , and select Management under the Admin column.
From the NetQ Management workbench, you can view the number of users with accounts in the system. As an administrator, you can also add, modify, and delete user accounts using the User Accounts card.
Add New User Account
For each user that monitors at least one aspect of your data center
network, a user account is needed. Adding a local user is described here. Refer to Integrate NetQ with Your LDAP server for instructions for adding LDAP users.
To add a new user account:
Click Manage on the User Accounts card to open the User Accounts tab.
Click Add User.
Enter the user’s email address, along with their first and last name.
Be especially careful entering the email address as you cannot change it once you save the account. If you save a mistyped email address, you must delete the account and create a new one.
Select the user type: Admin or User.
Enter your password in the Admin Password field (only users with administrative permissions can add users).
Create a password for the user.
Enter a password for the user.
Re-enter the user password. If you do not enter a matching password, it will be underlined in red.
Click Save to create the user account, or Cancel to discard the user account.
By default the User Accounts table is sorted by Role.
Repeat these steps to add all of your users.
Edit a User Name
If a user’s first or last name was incorrectly entered, you can fix them easily.
To change a user name:
Click Manage on the User Accounts card to open the User Accounts tab.
Click the checkbox next to the account you want to edit.
Click above the account list.

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:

Manage Monitoring of 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 of VM from the NetQ Management dashboard.
To view the server information:
Click .
Select Management from the Admin column.
Locate the System Server Info card.
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.
What's New
Cumulus NetQ 3.0 adds significant functionality improvements that streamline network operations and eliminate barriers to adoption of open networking for your customers. Included in the updated software are lifecycle Management (LCM) capabilities that enable NetQ to deliver upgrade and configuration management with push button simplicity.
You can upgrade from NetQ 2.4.x to NetQ 3.0.0. Upgrades from NetQ 2.3.x and earlier require a fresh installation.
Cumulus NetQ 3.0.0 includes the following new features and improvements:
Lifecycle Management support for Cumulus Linux upgrade on monitored switches (NetQ UI or CLI)
Simple NetQ UI workflow to prepare, run upgrade jobs, and evaluate results
Option to automatically generate before and after network snapshots for comparison
Option to roll back to previous CL version in the event of upgrade failure
Embedded NetQ UI application help, with step-by-step instructions and link to user documentation
Password change required on first login to NetQ UI

Tune NetQ Agent polling for events and resources, and specify polling frequency using netq config agent command command set
Specify a list of hostnames when running netq check commands
View additional statistics from netq <hostname> show ethtool-status command
Ported Python 2 codebase to Python 3
LNV support has been removed as of this release.
For information regarding bug fixes and known issues present in this release, refer to the release notes.
Lifecycle Management
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 initial lifecycle management (LCM) feature of network Snapshot and Compare to support Cumulus Linux image, switch, and credential management, and a UI workflow for the Cumulus Linux image installation and upgrade, including backup and restoration of the switch configuration files. Each of these features can be managed separately, but the greatest benefits are seen when they are used together in the workflow.
This feature is only available for on-premises deployments.
Access Lifecycle Management Features
To manage the various lifecycle management features, click (Main Menu) and select Upgrade Switches.
The Manage Switch Assets view provides a summary card for switch inventory, uploaded images, and switch access settings.
If you have a workbench open, you can also access this view by clicking (Upgrade) in the workbench header.
Image Management
Cumulus Linux binary images can be uploaded to a local LCM repository for use with installation and upgrade of your switches. You can upload images from an external drive. When NetQ discovers Cumulus Linux switches running NetQ 2.4 or later in your network, it extracts the meta data needed to select the appropriate image for a given switch; including the software version (x.y.z), the CPU architecture (ARM, x86), platform (based on ASIC vendor, Broadcom or Mellanox) and SHA Checksum.
The Cumulus Linux Images card provides a summary of image status in NetQ. It shows the total number of images in the repository, a count of missing images (refer to Missing Images), and the starting points for adding and managing your images.
Default Cumulus Linux Version Assignment
You can assign a specific Cumulus Linux version as the default version to use during installation or upgrade of switches. Choosing the version that is desired for the largest number of your switches is recommended. The default selection can be overridden during upgrade job creation if an alternate version is needed for a set of switches.
Missing Images
You should upload images for each variant of Cumulus Linux currently installed on your switch inventory if you want to support rolling back to a known good version should an installation or upgrade fail. NetQ 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 NetQ would verify 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, NetQ would list the 3.7.11 ARM image as missing.
If you have specified a default Cumulus Linux version, NetQ also verifies that the necessary images are available based on the known switch inventory, and if not, lists those that are missing.
Upload Images
On installation of NetQ 3.0, no images have yet been uploaded to the LCM repository. Begin by adding images that match your current inventory. Then add the image you want to use for upgrading. And finally specify a default image for upgrades, if desired.
Upload Missing Images
To upload missing 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.
Select one of the missing images and make note of the version, ASIC Vendor, and CPU architecture.
Click (Add Image) above the table.
Provide the .bin file 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 tab to verify the image is in the repository.
Repeat Steps 1-7 until all of the missing images are uploaded to 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 Cumulus Linux Images card now shows the number of images you uploaded.
Upload Upgrade Images
To upload the Cumulus Linux images that you want to use for upgrade:
Click Add Image on the Cumulus Linux Images card.
Provide an image from an external drive, either by dragging and dropping it onto the dialog or by selecting it from a directory.
Click Import.
Click Done.
Repeat Steps 1-4 to upload additional images as needed.
For example, if you are upgrading switches with different ASIC vendors or CPU architectures, you will need more than one image.
Specify a Default Image for Upgrade
Lifecycle management does not have a default Cumulus Linux image specified automatically. You must specify the image that is appropriate for your network.
To specify a default Cumulus Linux image:
Click the Click here to set the default CL version link in the middle of the Cumulus Linux Images card.
Select the image you want to use as the default image for switch upgrades.
Click Save. The default version is now displayed on the Cumulus Linux Images card.
After you have specified a default image, you have the option to change it.
To change the default Cumulus Linux image:
Click change next to the currently identified default image on the Cumulus Linux Images card.
Select the image you want to use as the default image for switch upgrades.
Click Save.
Export Images
Once you have images uploaded to the NetQ LCM repository, you are able to export those images.
To export images:
Open the LCM dashboard.
Click Manage on the Cumulus Linux Images card.
Select the images you want to export from the Uploaded tab. Use the filter option above the table to narrow down a large listing of images.
Click above the table.
Choose the export file type and click Export.
Remove Images from Local Repository
Once you have upgraded all of your switches beyond a particular release of Cumulus Linux, you may want to remove any associated images from the NetQ LCM repository to save space on the server.
To remove images:
Open the LCM dashboard.
Click Manage on the Cumulus Linux Images card.
On the Uploaded tab, select the images you want to remove. Use the filter option above the table to narrow down a large listing of images.
Click .
Credential Management
Switch access credentials are needed for performing upgrades. You can choose between basic authentication (SSH password) and SSH (Public/Private key) authentication. These credentials apply to all switches.
Specify Switch Credentials
Switch access credentials are not specified by default. You must add these.
To specify access credentials:
Open the LCM dashboard.
Click the Click here to add switch access link on the Access card.
Select the authentication method you want to use; SSH or Basic Authentication. Basic authentication is selected by default.
Enter a username.
Enter a password.
Click Save.
The Access card now indicates your credential configuration.
You must have sudoer permission to properly configure switches when using the SSH Key method.
Create a pair of SSH private and public keys.
ssh-keygen -t rsa -C "<USER>"
Copy the SSH public key to each switch that you want to upgrade using one of the following methods:
Manually copy SSH public key to the /home/<USER>/.ssh/authorized_keys file on each switches, or
Run ssh-copy-id USER@<switch_ip> on the server where the SSH key pair was generated for each switch
Copy the SSH private key into the text box in the Create Switch Access card.
For security, your private key is stored in an encrypted format, and only provided to internal processes while encrypted.
The Access card now indicates your credential configuration.
Modify Switch Credentials
You can modify your switch access credentials at any time. You can change between authentication methods or change values for either method.
To change your access credentials:
Open the LCM dashboard.
On the Access card, click the Click here to change access mode link in the center of the card.
Select the authentication method you want to use; SSH or Basic Authentication. Basic authentication is selected by default.
This lifecycle management feature provides an inventory of switches that have been automatically discovered by NetQ 3.0.0 and are available for software installation or upgrade through NetQ. This includes all switches running 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.
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, filtering as needed (click ) to determine if the switches you want to upgrade are included.
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.
If the switches you are looking to upgrade are not present in the final list, verify the switches have NetQ 2.4 or later Agents on them.
To verify the NetQ Agent version, click , then click Agents in the Network section. Search for the switches of interest and confirm the applied version in the Version column. Upgrade any NetQ Agents if needed. Refer to Upgrade NetQ Agents for instructions.
After all of the switches you want to upgrade are contained in the list, you can assign roles to them.
Role Management
Four pre-defined switch roles are available based on the CLOS architecture:
Superspine
Spine
Leaf
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
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.
Change the Role of a Switch
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 switch with the incorrect role from the list.
Click .
Select the correct role.
Click Assign.
Export List of Switches
Using the Switch Management feature you can export a listing of all or a selected set of switches.
To export the switch listing:
Open the LCM dashboard.
On the Switches card, click Manage.
Select one or more switches, filtering as needed, or select all switches (click ).
Click .
Choose the export file type and click Export.
Network Snapshot and Compare
Creating and comparing network snapshots can be used at various times; typically when you are upgrading or changing the configuration of your switches in some way. The instructions here describe how to create and compare network snapshots at any time. Refer to Image Installation and Upgrade to see how snapshots are automatically created in that workflow to validate that the network state has not changed after an 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, click in the workbench header.
Click Create Snapshot.
Enter a name for the snapshot.
Accept the time provided or enter a previous date and time.
Optionally, add a descriptive note for the snapshot.
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).
Compare Network Snapshots
You can compare the state of your network before and after an upgrade or other configuration change to validate the changes.
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:
If you have the two desired snapshot cards open:
Simply put them 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.
If you have only one of the cards open:
Click Compare on the open card.
Select the other snapshot to compare.
If no snapshot cards are open (you may have created them some time before):
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:

Cumulus Linux Upgrade
The workflow for installation and upgrade of Cumulus Linux using LCM is to: select switches, choose options, run pre-checks, view job preview, begin job, monitor job, review snapshot comparison and analyze as needed. Up to five jobs can be run simultaneously; however, a given switch can only be contained in one of those jobs.
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.
Prepare
In preparation for switch installation or upgrade, first perform the following steps:
Verify the switches you want to manage are running NetQ Agent 2.4 or later. Refer to Switch Management.
Assign each switch a role (optional, but recommended). Refer to Role Management.
Your LCM dashboard should look similar to this after you have completed these steps:
Perform Install or Upgrade
To install or upgrade switches:
Click (Main Menu) and select Upgrade Switches, or click (Upgrade) in a workbench header.
Click Manage on the Switches card.
Select the switches you want to upgrade. If needed, use the filter to the narrow the listing and find these switches.
Click (Upgrade Switches) 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.
For best presentation, Cumulus Networks recommends keeping the name to a maximum of 22 characters when possible. The name can contain spaces and special characters. If you choose to use longer names, use the distinguishing part of the name at the beginning.
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 to select a role for that switch, then click . Click to discard a role change.
In this example, some of the selected switches do not have roles assigned.
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 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.
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 one or more of the pre-checks fail, resolve the related issue and start the upgrade again. Expand the following dropdown to view common failures, their causes and corrective actions.
