NetQ Overview
This section describes NetQ components and deployment models. It also outlines how to get started with the NetQ user interface and command line.
NetQ Basics
This section provides an overview of the NetQ hardware, software, and deployment models.
NetQ Components
NetQ contains the following applications and key components:
Telemetry data collection and aggregation via
NetQ switch agents
NetQ host agents
Database
Data streaming
Network services
User interfaces
While these functions apply to both the on-premises and cloud solutions, they are configured differently, as shown in the following diagrams.
NetQ Agents
NetQ Agents are installed via software and run 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 or SONiC switches gather the following network data via Netlink:
Interfaces
IP addresses (v4 and v6)
IP routes (v4 and v6)
IP nexthops (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
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.
NetQ Core
The NetQ core performs the data collection, storage, and processing for delivery to various user interfaces. It consists of a collection of scalable components running entirely within a single server. The NetQ software queries this server, rather than individual devices, enabling greater system scalability.
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, sending notifications about events 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
NetQ uses two types of data stores. 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 raw-data processing.
Real-time Streaming
The streaming component processes the incoming raw data from the aggregation server in real time. It reads the metrics and stores them as a time series, and triggers alarms based on anomaly detection, thresholds, and events.
Network Services
The network services component monitors protocols and services operation individually and on a networkwide basis and stores status details.
User Interfaces
NetQ data is available through several interfaces:
NetQ CLI (command-line interface)
NetQ GUI (graphical user interface)
NetQ RESTful API (representational state transfer application programming interface)
The CLI and UI query the RESTful API to present data. NetQ can integrate with event notification applications and third-party analytics tools.
Data Center Network Deployments
This section describes three common data center deployment types for network management:
Out-of-band management (recommended)
In-band management
Server cluster with high availability
NetQ operates over layer 3, and can operate in both layer-2 bridged and layer-3 routed environments. NVIDIA recommends a layer-3 routed environment whenever possible.
Out-of-band Management Deployment
NVIDIA recommends deploying NetQ on an out-of-band (OOB) management network to separate network management traffic from standard network data traffic.
The physical network hardware includes:
Spine switches: aggregate and distribute data; 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: host applications and data served to the user through the network
Exit switch: where connections to outside the data center occur, also known as a border leaf or service leaf
Edge server (optional): where the firewall is the demarcation point, peering can occur through the exit switch layer to Internet (PE) devices
Internet device: where provider edge (PE) equipment communicates at layer 3 with the network fabric
The following figure shows an example of a Clos network fabric design for a data center using an OOB management network overlaid on top, where NetQ resides. The physical connections are displayed as gray lines, connecting Spine01 to four leaf and two exit devices; Spine02 is connected to the same leaf and exit devices. Leaf01 and Leaf02 connect to each other over a peerlink and act as an MLAG pair for Server01 and Server02, as do Leaf03 and Leaf04 for Server03 and Server04. The edge connects to both exit devices, and the Internet node connects to Exit01.
The physical management hardware includes:
OOB management switch: aggregation switch that connects to all network devices through communications with the NetQ Agent on each node
NetQ Platform: hosts the telemetry software, database, and user interfaces
These switches connect to each physical network device through a virtual network overlay, as shown below.
In-band Management Deployment
While not recommended, you can 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. Certain features—such as lifecycle management—require additional configurations for in-band deployments.
Server Cluster Deployments
NetQ supports a server cluster deployment for users who prefer a solution with increased scalability and availability; the data collected by NetQ remains available through additional servers should one fail. In this configuration, three NetQ servers are deployed—one master and two workers (or replicas). NetQ Agents send data to all three servers so that if the master server fails, one of the replicas automatically becomes the master and continues to store the telemetry data. Both on-premises and cloud (OPTA) cluster deployments support high availability through a virtual IP address that is allocated in the same subnet as the master and worker nodes. This allows for UI access in the case of a master node failure.
The following example is based on an OOB-management configuration, and modified to support higher scalability for NetQ.
NetQ Operation
In either in-band or out-of-band deployments, NetQ offers networkwide configuration and device management, proactive monitoring capabilities, and network performance diagnostics.
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 network switch is similar to the following diagram:
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 Linux supports BGP and OSPF routing protocols as well as static addressing through FRRouting (FRR). Cumulus Linux also supports LLDP and MSTP among other protocols, and a variety of services such as systemd and sensors. SONiC supports BGP and LLDP.
For hosts, the NetQ Agent also polls for performance of containers managed with Kubernetes. This information is used to calculate the network’s health and check if the network is configured and operating correctly.
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 sends notifications about these changes so that network operators and administrators can respond quickly when changes are not expected or favorable.
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. The agent measures operational states and temperatures, along with cabling information to allow for proactive maintenance.
The NetQ Platform
After the collected data is sent to and stored in the NetQ database, you can:
Validate configurations and identify misconfigurations in your current network or in a previous deployment.
Monitor communication paths throughout the network.
Notify users of network issues.
Anticipate the impact of connectivity changes.
Validate Configurations
You can monitor and validate your network’s health in the UI or through two sets of commands: netq check and netq show. They extract the information from the network service component and event service. The network service component is continually validating the connectivity and configuration of the devices and protocols running on the network. Using the netq check and netq show commands displays the status of the various components and services on a networkwide and complete software stack basis. See the command line reference for an exhaustive list of netq check and netq show commands.
Monitor Communication Paths
The trace engine validates 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. For more information about trace requests, refer to Verify Network Connectivity.
View Historical State and Configuration Info
You can run all check, show, and trace commands for current and past statuses. To investigate past issues, use the netq check command and look for configuration or operational issues around the time that NetQ timestamped event messages. Then use the netq show commands to view information about device configurations. You can also use the netq trace command to see what the connectivity looked like between any problematic nodes at a particular time.
For example, the following diagram shows issues on spine01, leaf04, and server03:
An administrator can run the following commands from any switch in the network to determine the cause of a BGP error on spine01:

Manage Network Events
The NetQ notifier lets you capture and filter events for devices, components, protocols, and services. 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. You can improve resolution time significantly by creating filters that focus on topics appropriate for a particular group of users. You can create filters for events related to BGP and MLAG session states, interfaces, links, NTP and other services, fans, power supplies, and physical sensor measurements.
The following 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:
Every event or entry in the NetQ database is stored with a timestamp that reports when the NetQ Agent captured an event 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.
Interface state, IP addresses, routes, ARP/ND table (IP neighbor) entries and MAC table entries carry a timestamp that represents the time an event occurred (such as when a route is deleted or an interface comes up).
Data that is captured and saved based on polling has a timestamp according to 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.
Restarting a NetQ Agent on a device does not update the timestamps for existing objects to reflect this new restart time. NetQ preserves their timestamps relative to the original start time of the Agent. A rare exception is if you reboot the device between the time it takes the Agent to stop and restart; in this case, the time is still relative to the start time of the Agent.
Exporting NetQ Data
You can export data from the NetQ Platform in the CLI or UI:
In the CLI, use the json option to output command results to JSON format for parsing in other applications
In the UI, expand the cards to a full-screen, tabular view and select Export.

NetQ Command Line Overview
The NetQ CLI provides access to all network state and event information collected by NetQ Agents. It behaves similarly to typical CLIs, with groups of commands that display related information, and help commands that provide additional information. See the command line reference for a comprehensive list of NetQ commands, including examples, options, and definitions.
The NetQ command line interface only runs on switches and server hosts implemented with Intel x86 or ARM-based architectures.
CLI Access
When you install or upgrade NetQ, you can also install and enable the CLI on your NetQ server or appliance and hosts.
To access the CLI from a switch or server:
Log in to the device. The following 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!
You can now run commands:
cumulus@switch:~$ netq show agents
Command Line Basics
This section describes the core structure and behavior of the NetQ CLI.
Command Line Structure
The NetQ command line has a flat structure as opposed to a modal structure: you can run all commands from the standard command prompt instead of only in a specific mode, at the same level.
Command Syntax
All NetQ CLI commands begin with netq. The commands you use to monitor your network 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.
Command Output
The command output presents results in color for many commands. Results with errors appear in red, and warnings appear in yellow. Results without errors or warnings appear in either black or green. VTEPs appear in blue. A node in the pretty output appears in bold, and angle brackets (< >) wrap around a router interface. 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 have a default timeframe of now to one hour ago, unless you specify an approximate time using the around keyword or a range using the between 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.
When entering a time value, you must include a numeric value and the unit of measure:
w: weeks
d: days
h: hours
m: minutes
s: seconds
now
When using the between option, you can enter the start time (text-time) and end time (text-endtime) values as most recent first and least recent second, or vice versa. The values do not have to have the same unit of measure. Use the around option to view information for a particular time.
Command Prompts
NetQ code examples use the following prompts:
cumulus@switch:~$ indicates the user cumulus is logged in to a switch to run the example command
cumulus@host:~$ indicates the user cumulus is logged in to a host to run the example command
cumulus@netq-appliance:~$ indicates the user cumulus is logged in to either the NetQ Appliance or NetQ Cloud Appliance to run the command
cumulus@hostname:~$ indicates the user cumulus is logged in to a switch, host or appliance to run the example command
To use the NetQ CLI, the switches must be running the Cumulus Linux or SONiC operating system, NetQ Platform or NetQ Collector software, the NetQ Agent, and the NetQ CLI. The hosts must be running CentOS, RHEL, or Ubuntu OS, the NetQ Agent, and the NetQ CLI. Refer to Install NetQ for additional information.
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>>
addresses : IPv4/v6 addresses
agents : Netq agent
bgp : BGP info
cl-version : Cumulus Linux version
evpn : EVPN
interfaces : network interface port
mlag : Multi-chassis LAG (alias of clag)
mtu : Link MTU
ntp : NTP
ospf : OSPF info
roce : RoCE
sensors : Temperature/Fan/PSU sensors
vlan : VLAN
vxlan : VxLAN
cumulus@switch:~$ netq check
Command Help
As you enter commands, you can get help with command syntax by entering help as part of the command. For example, to find out which options are available for an IP addresses check, enter the netq check addresses command followed by help:
To see an exhaustive list of commands and their definitions, run:
cumulus@switch:~$ netq help list
To display NetQ command formatting rules, run:
cumulus@switch:~$ netq help verbose
Command History
The CLI stores commands issued within a session, which lets you review and rerun commands that you already ran. 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. You can also modify the command before you run it.
Command Categories
While the CLI has a flat structure, NetQ commands are conceptually grouped into the following functional categories:
The netq check commands 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. You can perform validation checks for the following:
addresses: IPv4 and IPv6 addresses duplicates across devices
agents: NetQ Agents operation on all switches and hosts
bgp: BGP (Border Gateway Protocol) operation across the network
fabric
clag: Cumulus Linux MLAG (multi-chassis LAG/link aggregation) operation
The netq show commands let you view details about the current or historical configuration and status of various protocols and services.
The commands take the form of netq [<hostname>] show <network-protocol-or-service> [options], where the options vary according to the protocol or service. You can restrict the commands from showing the information for all devices to showing information only for a selected device using the hostname option.

Configuration Commands
Various commands—netq config, netq lcm, netq add, and netq del—allow you to manage NetQ Agent and CLI server configurations, configure lifecycle management, set up container monitoring, and manage notifications.
NetQ Agent Configuration
The agent commands configure individual NetQ Agents.
The agent configuration commands can add and remove agents from switches and hosts, start and stop agent operations, debug the agent, specify default commands, and enable or disable a variety of monitoring features (including sensors, FRR (FRRouting), CPU usage limit, and What Just Happened).
Commands apply to one agent at a time. Run them from the switch or host where the NetQ Agent resides. You must run the netq config commands with sudo privileges.
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.
The netq config cli configures and manages the CLI component. You can add or remove the 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 you run them from the switch or host where you run the CLI.
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
netq config select cli premise
The following example shows how to restart the CLI instance:
cumulus@switch~:$ netq config restart cli
The following example shows how to enable the CLI on a NetQ on-premises appliance or virtual machine:
cumulus@switch~:$ netq config add cli server 10.1.3.101
NetQ System Configuration Commands
Use the following commands to manage the NetQ system itself:
bootstrap: Loads the installation program onto the network switches and hosts in either a single server or server cluster arrangement.
decommission: Decommissions a switch or host.
install: Installs NetQ in standalone or cluster deployments; also used to install patch software.
upgrade bundle: Upgrades NetQ on NetQ on-premises appliances or VMs.
The following example shows how to decommission a switch named leaf01:
For information and examples on installing and upgrading the NetQ system, see Install NetQ and Upgrade NetQ.
Event Notification Commands
The notification configuration commands can add, remove, and show notification via third-party integrations. These commands create the channels, filters, and rules that display event messages. Refer to Configure System Event Notifications for step-by-step instructions and examples.
Threshold-based Event Notification Commands
NetQ supports TCA events, a set of events that are triggered by crossing a user-defined threshold. Configure and manage TCA events using the following commands:
netq add tca
netq del tca tca_id <text-tca-id-anchor>
netq show tca
Lifecycle Management Commands
The lifecycle management commands help you efficiently manage the deployment of NVIDIA product software onto your network devices (servers, appliances, and switches).
LCM commands allow you to:
Manage network OS and NetQ images in a local repository
Configure switch access credentials for installations and upgrades
Manage switch inventory and roles
Install or upgrade NetQ Agents and CLI on switches
Upgrade the network OS on switches with NetQ Agents
View a result history of upgrade attempts
Add or delete NetQ configuration profiles
The following example shows the NetQ configuration profiles:

The following example shows how to add a Cumulus Linux installation image to the NetQ repository on the switch:
The netq trace commands let you view the available paths between two nodes on the network. You can perform a layer 2 or layer 3 trace, and view the output in one of three formats: JSON, pretty, and detail. JSON output provides the output in a JSON file format for ease of importing to other applications or software. Pretty output lines up the paths in a pseudo-graphical manner to help visualize multiple paths. Detail output is useful for traces with higher hop counts where the pretty output wraps lines, making it harder to interpret the results. The detail output displays a table with a row for each path.
This section describes how to install, configure, and upgrade NetQ.
Before you begin, review the release notes for this version.
Before You Install
This overview is designed to help you understand the various NetQ deployment and installation options.
Installation Overview
Consider the following before you install the NetQ system:
Determine whether to deploy fully on-premises or as a remote solution.
Choose whether to install the software on a single server or as a server cluster.
Deployment Type: On-premises or Remote
You can deploy NetQ in one of two ways:
Hosted on-premises: Choose this deployment if you want to host at your location and have the in-house skill set to install, configure, back up, and maintain NetQ. 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, or if you have data-residency requirements like GDPR.
Hosted remotely: Choose this deployment to host a multi-site, on-premises deployment or use NetQ Cloud. In the multi-site deployment, you host multiple small servers at each site and an on-premises appliance at a central location. In the cloud deployment, you host only a small, local server on your premises that connects to the NetQ Cloud service over selected ports or through a proxy server. NetQ Cloud supports local data aggregation and forwarding—the majority of the NetQ applications use a hosted deployment strategy, storing data in the cloud. NVIDIA handles the backups and maintenance of the application and storage. This remote cloud service model is a good choice when you have limited in-house support or if you need the flexibility to scale quickly, while also reducing capital expenses.
In all deployment models, the NetQ Agents reside on the switches and hosts they monitor in your network. Refer to Install the NetQ System for a comprehensive list of deployment types and their respective requirements.
Data Flow
The flow of data differs based on your deployment model.
For the on-premises deployment, the NetQ Agents collect and transmit data from the switches and hosts back to the NetQ on-premises appliance running the NetQ software. The software processes and stores the data, which is then displayed through the user interface.
For the remote, multi-site NetQ implementation, the NetQ Agents at each secondary premises collect and transmit data from the switches and hosts from the secondary premises to the NetQ cloud appliance. The cloud appliance transmits this data to the primary NetQ on-premises appliance for processing and storage. This deployment is a good choice when you want to store all the data from multiple premises on one NetQ on-premises appliance.
For the remote, cloud-service implementation, the NetQ Agents collect and transmit data from the switches and hosts to the NetQ cloud appliance. The NetQ cloud appliance then transmits this data to the NVIDIA cloud-based infrastructure for further processing and storage.
Both single-server and server-cluster deployments provide identical services and features. The biggest difference is the number of servers deployed and 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. Deploying multiple servers is 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. The clustering implementation comprises three servers: one master and two workers. Part of the cluster configuration includes configuring the NetQ Agents to connect to the three servers.
Cluster Deployments and Kubernetes
NetQ supports high availability server-cluster deployments using a virtual IP address. Even if the master node fails, NetQ services remain operational. However, keep in mind that the master hosts the Kubernetes control plane so anything that requires connectivity with the Kubernetes cluster—such as upgrading NetQ or rescheduling pods to other workers if a worker goes down—will not work.
During the installation process, you configure a virtual IP address that enables redundancy for the Kubernetes control plane. In this configuration, the majority of nodes must be operational for NetQ to function. For example, a three-node cluster can tolerate a one-node failure, but not a two-node failure.
Cluster Deployments and Load Balancers
As an alternative to the high availability server-cluster deployment with a virtual IP address, you can use an external load balancer to provide high availability for the NetQ API and the NetQ UI.
However, you need to be mindful of where you install the certificates for the NetQ UI (port 443); otherwise, you cannot access the NetQ UI. If you are using a load balancer in your deployment, NVIDIA recommends that you install the certificates directly on the load balancer for SSL offloading. However, if you install the certificates on the master node, then configure the load balancer to allow for SSL passthrough.
Next Steps
After you’ve decided on your deployment type, you’re ready to install NetQ.
You can install NetQ either on your premises or as a remote, cloud solution. If you are unsure which option is best for your network, refer to Before You Install.
After installing the NetQ software, you should install the NetQ Agents on each switch you want to monitor. You can install NetQ Agents on switches and servers running:
Cumulus Linux 5.0.0 to 5.8.0 (Spectrum switches)
Cumulus Linux 4.3.0, 4.3.1, and 4.3.2 (Broadcom switches)
SONiC 202012
CentOS 7
RHEL 7.1
Ubuntu 20.04
Prepare for NetQ Agent Installation
For switches running Cumulus Linux and SONiC, you need to:
Install and configure NTP or PTP, if needed
Obtain NetQ software packages
For servers running RHEL, CentOS, or Ubuntu, you need to:
Verify you installed the minimum package versions
Verify the server is running lldpd
Install and configure NTP or PTP, 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 NVIDIA networking repository.
Verify NTP Is Installed and Configured
Verify that
NTP is running on the switch as outlined in the steps below. The switch system clock must be synchronized with the NetQ appliance to enable useful statistical analysis. Alternatively, you can configure
PTP for time synchronization.
cumulus@switch:~$ sudo systemctl status ntp
[sudo] password for cumulus:
● ntp.service - LSB: Start NTP daemon

└─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
Cumulus Linux 4.4 and later includes the netq-agent package by default. To upgrade the NetQ Agent to the latest version:
Add the repository by uncommenting or adding the following line in /etc/apt/sources.list:
cumulus@switch:~$ sudo nano /etc/apt/sources.list
...
deb https://apps3.cumulusnetworks.com/repos/deb CumulusLinux-4 netq-4.9
...
You can specify a NetQ Agent version in the repository configuration. The following example shows the repository configuration to retrieve NetQ Agent 4.3:
deb https://apps3.cumulusnetworks.com/repos/deb CumulusLinux-4 netq-4.3
Add the apps3.cumulusnetworks.com authentication key to Cumulus Linux:
Verify that
NTP is running on the switch as outlined in the steps below. The switch must be synchronized with the NetQ appliance to enable useful statistical analysis. Alternatively, you can configure
PTP for time synchronization.
admin@switch:~$ sudo systemctl status ntp
● ntp.service - Network Time Service

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 NVIDIA networking repository.
Note that NetQ has a separate repository from SONiC.
To obtain the NetQ Agent package:
Install the wget utility so that you can install the GPG keys in step 3.
Before you install the NetQ Agent on a Red Hat or CentOS server, make sure you install and run at least the minimum versions of the following packages:
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; however, the installation requires it.
To install this package, run the following commands:
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-4.9
...
Create the file /etc/apt/sources.list.d/cumulus-host-ubuntu-focal.list and add the following line:
root@ubuntu:~# vi /etc/apt/sources.list.d/cumulus-apps-deb-focal.list
...
deb [arch=amd64] https://apps3.cumulusnetworks.com/repos/deb focal netq-4.9
...
Install NetQ Agent
After completing the preparation steps, install the agent on your switch or host.
Cumulus Linux 4.4 and later includes the netq-agent package by default. To install the NetQ Agent on earlier versions of Cumulus Linux:
Update the local apt repository, then install the NetQ software on the switch.
Configure the NetQ Agent, as described in the next section.
Configure NetQ Agent
After you install the NetQ Agents on the switches you want to monitor, you must configure them to obtain useful and relevant data.
The NetQ Agent is aware of and communicates through the designated VRF. If you do not specify one, it uses the default VRF (named default). 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.
If you configure the NetQ Agent to communicate in a VRF that is not default or mgmt, the following line must be added to /etc/netq/netq.yml in the netq-agent section:
netq-agent:
netq_stream_address: 0.0.0.0
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:
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 server where the agent should send its collected data
vrf: default (or one that you specify)
inband-interface: the interface used to reach your NetQ server and used by lifecycle management to connect to the switch (for deployments where switches are managed through an in-band interface)
If you configured the NetQ CLI, you can use it to configure the NetQ Agent to send telemetry data to the NetQ appliance or VM. To configure the NetQ CLI, refer to Install NetQ CLI.
This example uses a NetQ server IP address of 192.168.1.254, the default port, and the mgmt VRF for a switch managed through an out-of-band connection:
This example uses a NetQ server IP address of 192.168.1.254, the default port, and the default VRF for a switch managed through an in-band connection on interface swp1:
A couple of additional options are available for configuring the NetQ Agent. If you are using VRFs, 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
By default, NetQ uses the default VRF for communication between the NetQ appliance or VM and NetQ Agents. While optional, NVIDIA 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 you configured the management VRF and you want the agent to communicate with the NetQ appliance or VM over it, configure the agent like this:
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.
Configure the Agent to Communicate over a Specific Port
By default, NetQ uses port 31980 for communication between the NetQ server and NetQ Agents for on-premises deployments and port 443 for cloud deployments. If you want the NetQ Agent to communicate with the NetQ sever via a different port, you need to specify the port number when configuring the NetQ Agent, like this:
sudo netq config add agent server 192.168.1.254 port 7379
sudo netq config restart agent
Installing the NetQ CLI on your NetQ VMs, switches, or hosts gives you access to new features and bug fixes, and allows you to manage your network from multiple points in the network.
After installing the NetQ software and agent on each switch you want to monitor, you can also install the NetQ CLI on switches running:
Cumulus Linux 5.0.0 to 5.8.0 (Spectrum switches)
Cumulus Linux 4.3.0, 4.3.1, and 4.3.2 (Broadcom switches)
SONiC 202012
CentOS 7
RHEL 7.1
Ubuntu 20.04
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 NetQ repository.
Prepare for NetQ CLI Installation on a RHEL, CentOS, or Ubuntu Server
For servers running RHEL 7, CentOS or Ubuntu OS, you need to:
Verify you installed the minimum service packages versions
Verify the server is running lldpd
Install and configure NTP or PTP, if needed
Obtain NetQ software packages
These steps are not required for Cumulus Linux or SONiC.

For CentOS and Ubuntu, make sure you are running lldpd, not lldpad. CentOS and Ubuntu do not include lldpd by default, even though the installation requires it. You must also install the Wget utility on CentOS distributions.
To install the packages, run the following commands:
If you are running NTP in your out-of-band management network with VRF, specify the VRF (ntp@<vrf-name> versus just ntp) in the above commands.
Verify NTP is operating correctly. Look for an asterisk (*) or a plus sign (+) that indicates the clock synchronized with NTP.

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-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-4.9

Install NetQ CLI
Follow these steps to install the NetQ CLI on a switch or host.
Cumulus Linux 4.4 and later includes the netq-apps package by default. To upgrade the NetQ CLI to the latest version:
Add the repository by uncommenting or adding the following line in /etc/apt/sources.list:
cumulus@switch:~$ sudo nano /etc/apt/sources.list
...
deb https://apps3.cumulusnetworks.com/repos/deb CumulusLinux-4 netq-4.9
...
You can specify a NetQ CLI version in the repository configuration. The following example shows the repository configuration to retrieve NetQ CLI v4.3:
deb https://apps3.cumulusnetworks.com/repos/deb CumulusLinux-4 netq-4.3
Update the local apt repository and install the software on the switch.
Continue with NetQ CLI configuration in the next section.
To install the NetQ CLI you need to install netq-apps on each switch. This is available from the NVIDIA networking 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 NVIDIA networking repository.
To obtain the NetQ CLI package:
Edit the /etc/apt/sources.list file to add the repository for NetQ.
Continue with NetQ CLI configuration in the next section.
Configure the NetQ CLI
By default, you do not configure the NetQ CLI during the NetQ installation. The configuration resides in the /etc/netq/netq.yml file. Until the CLI is configured on a device, you can only run netq config and netq help commands, and you must use sudo to run them.
At minimum, you need to configure the NetQ CLI and NetQ Agent to communicate with the telemetry server. To do so, configure the NetQ Agent and the NetQ CLI so that they are running in the VRF where the routing tables have connectivity to the telemetry server (typically the management VRF).
To access and configure the CLI for your on-premises NetQ deployment, you must generate AuthKeys. You’ll need your username and password to generate them. These keys provide authorized access (access key) and user authentication (secret key).
To generate AuthKeys:
Enter your on-premises NetQ appliance hostname or IP address into your browser to open the NetQ UI login page.
Enter your username and password.
Expand the Menu, then select Management.
On the User Accounts card, select Manage.
Select your user and click Generate keys above the table.
Copy these keys to a safe place. Select Copy to obtain the CLI configuration command to use on your devices.
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
The following example uses the individual access key, a premises of datacenterwest, and the default Cloud address, port and VRF. Replace the key values with your generated keys if you are using this example on your server.
This example uses an optional keys file. Replace the keys filename and path with the full path and name of your keys file, and the datacenterwest premises name with your premises name if you are using this example on your server.
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.
To access and configure the CLI for your NetQ cloud deployment, you must generate AuthKeys. You’ll need your username and password to generate them. These keys provide authorized access (access key) and user authentication (secret key). Your credentials and NetQ Cloud addresses were obtained during your initial login to the NetQ Cloud and premises activation.
To generate AuthKeys:
Enter netq.nvidia.com into your browser to open the NetQ UI login page.
Enter your username and password.
Expand the Menu, then select Management.
On the User Accounts card, select Manage.
Select your user and click Generate keys above the table.
Copy these keys to a safe place. Select Copy to obtain the CLI configuration command to use on your devices.
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:

name the file whatever you like, for example credentials.yml, creds.yml, or keys.yml
The following example uses the individual access key, a premises of datacenterwest, and the default Cloud address, port and VRF. Replace the key values with your generated keys if you are using this example on your server.
sudo netq config add cli server api.netq.cumulusnetworks.com access-key 123452d9bc2850a1726f55534279dd3c8b3ec55e8b25144d4739dfddabe8149e secret-key /vAGywae2E4xVZg8F+HtS6h6yHliZbBP6HXU3J98765= premises datacenterwest

Updated cli server api.netq.cumulusnetworks.com vrf default port 443. Please restart netqd (netq config restart cli)
sudo netq config restart cli
Restarting NetQ CLI... Success!
The following example uses an optional keys file. Replace the keys filename and path with the full path and name of your keys file, and the datacenterwest premises name with your premises name if you are using this example on your server.
sudo netq config add cli server api.netq.cumulusnetworks.com cli-keys-file /home/netq/nq-cld-creds.yml premises datacenterwest
Successfully logged into NetQ cloud at api.netq.cumulusnetworks.com:443
Updated cli server api.netq.cumulusnetworks.com vrf default port 443. Please restart netqd (netq config restart cli)
sudo 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.

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 install CLI on the appliance. This example uses interface eth0. Replace this with your updated IP address, hostname or interface using the interface or ip-addr option.
cumulus@hostname:~$ netq install standalone full interface eth0 bundle /mnt/installables/NetQ-4.9.0.tgz
If this step fails for any reason, you can run netq bootstrap reset and then try again.

Add the same NEW_HOSTNAME value to /etc/hosts on your VM for the localhost entry. Example:
127.0.0.1 localhost NEW_HOSTNAME
Install and activate the NetQ software using the CLI:
Run the following command on your NetQ cloud appliance with the config-key obtained from the email you received from NVIDIA titled NetQ Access Link. You can also obtain the configuration key through the NetQ UI.
You can specify the IP address instead of the interface name here: use ip-addr <IP address> in place of interface <ifname> above.
If you have changed the IP address or hostname of the NetQ OPTA 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 install CLI on the appliance. This example uses interface eth0. Replace this with your updated IP address, hostname or interface using the interface or ip-addr option.
If this step fails for any reason, you can run netq bootstrap reset and then try again.
Consider the following for container environments, and make adjustments as needed.
Calico Networking
NetQ overrides the Calico default address range and changes it to 10.244.0.0/16. To modify this range, use the netq install opta command, specifying the default address range with the pod-ip-range option. For example:
The default Docker bridge interface is disabled in NetQ. If you need to reenable the interface, contact support.

cumulus@ubuntu:~$
Verify the master node is ready for installation. Fix any errors indicated before installing the NetQ software.
cumulus@hostname:~$ sudo opta-check-cloud
Change the hostname for the VM from the default value.
The default hostname for the NetQ Virtual Machines is ubuntu. Change the hostname to fit your naming conventions while meeting Internet and Kubernetes naming standards.
Kubernetes requires that hostnames are composed of a sequence of labels concatenated with dots. For example, “en.wikipedia.org” is a hostname. Each label must be from 1 to 63 characters long. The entire hostname, including the delimiting dots, has a maximum of 253 ASCII characters.
The Internet standards (RFCs) for protocols specify that labels may contain only the ASCII letters a through z (in lower case), the digits 0 through 9, and the hyphen-minus character ('-').
Add the same NEW_HOSTNAME value to /etc/hosts on your VM for the localhost entry. Example:
127.0.0.1 localhost NEW_HOSTNAME
Verify that your first worker node meets the VM requirements, as described in step 1.
Confirm that the required ports are open for communications, as described in step 2.
Open your hypervisor and set up the VM in the same manner as the master node.
Make a note of the private IP address you assign to the worker node. You will need it at a later point in the installation process.
Verify the worker node is ready for installation. Fix any errors indicated before installing the NetQ software.
cumulus@hostname:~$ sudo opta-check-cloud
Repeat steps 8 through 11 for each additional worker node in your cluster.
Install and activate the NetQ software using the CLI:
Run the following command on your master node to initialize the cluster. Copy the output of the command to use on your worker nodes:
cumulus@<hostname>:~$ netq install cluster master-init
Please run the following command on all worker nodes:
netq install cluster worker-init c3NoLXJzYSBBQUFBQjNOemFDMXljMkVBQUFBREFRQUJBQUFCQVFDM2NjTTZPdVVUWWJ5c2Q3NlJ4SHdseHBsOHQ4N2VMRWVGR05LSWFWVnVNcy94OEE4RFNMQVhKOHVKRjVLUXBnVjdKM2lnMGJpL2hDMVhmSVVjU3l3ZmhvVDVZM3dQN1oySVZVT29ZTi8vR1lOek5nVlNocWZQMDNDRW0xNnNmSzVvUWRQTzQzRFhxQ3NjbndIT3dwZmhRYy9MWTU1a
Run the netq install cluster worker-init <ssh-key> on each of your worker nodes.
Run the following command on your NetQ cloud appliance with the config-key obtained from the email you received from NVIDIA titled NetQ Access Link. You can also obtain the configuration key through the NetQ UI. Use the IP addresses of your worker nodes and the HA cluster virtual IP address (VIP).
The HA cluster virtual IP must be allocated from the same subnet used for your master and worker nodes.
You can specify the IP address instead of the interface name here: use ip-addr <IP address> in place of interface <ifname> above.
If you have changed the IP address or hostname of the NetQ OPTA 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 install CLI on the appliance. This example uses interface eth0. Replace this with your updated IP address, hostname or interface using the interface or ip-addr option.
If this step fails for any reason, you can run netq bootstrap reset and then try again.
Consider the following for container environments, and make adjustments as needed.
Calico Networking
NetQ overrides the Calico default address range and changes it to 10.244.0.0/16. To modify this range, use the netq install opta command, specifying the default address range with the pod-ip-range option. For example:
The default Docker bridge interface is disabled in NetQ. If you need to reenable the interface, contact support.

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.

cumulus@ubuntu:~$
Verify the master node 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 ('-').
Add the same NEW_HOSTNAME value to /etc/hosts on your VM for the localhost entry. Example:
127.0.0.1 localhost NEW_HOSTNAME
Verify that your first worker node meets the VM requirements, as described in step 1.
Confirm that the required ports are open for communications, as described in step 2.
Open your hypervisor and set up the VM in the same manner as for the master node.
Make a note of the private IP address you assign to the worker node. You need it for later installation steps.
Verify the worker node is ready for installation. Fix any errors indicated before installing the NetQ software.
cumulus@hostname:~$ sudo opta-check
Repeat steps 8 through 11 for each additional worker node in your cluster.
Install and activate the NetQ software using the CLI:
Run the following command on your master node to initialize the cluster. Copy the output of the command to use on your worker nodes:
cumulus@<hostname>:~$ netq install cluster master-init
Please run the following command on all worker nodes:
netq install cluster worker-init c3NoLXJzYSBBQUFBQjNOemFDMXljMkVBQUFBREFRQUJBQUFCQVFDM2NjTTZPdVVUWWJ5c2Q3NlJ4SHdseHBsOHQ4N2VMRWVGR05LSWFWVnVNcy94OEE4RFNMQVhKOHVKRjVLUXBnVjdKM2lnMGJpL2hDMVhmSVVjU3l3ZmhvVDVZM3dQN1oySVZVT29ZTi8vR1lOek5nVlNocWZQMDNDRW0xNnNmSzVvUWRQTzQzRFhxQ3NjbndIT3dwZmhRYy9MWTU1a
Run the netq install cluster worker-init <ssh-key> on each of your worker nodes.
Run the following commands on your master node, using the IP addresses of your worker nodes and the HA cluster virtual IP address (VIP):
The HA cluster virtual IP must be allocated from the same subnet used for your master and worker nodes.
Re-run the install CLI on the appliance. This example uses interface eth0. Replace this with your updated IP address, hostname or interface using the interface or ip-addr option.
If this step fails for any reason, you can run netq bootstrap reset and then try again.
Verify Installation Status
To view the status of the installation, use the netq show status [verbose] command. The following example shows a successful on-premises installation:

Verify the master node is ready for installation. Fix any errors indicated before installing the NetQ software.
cumulus@hostname:~$ sudo opta-check-cloud
Change the hostname for the VM from the default value.
The default hostname for the NetQ Virtual Machines is ubuntu. Change the hostname to fit your naming conventions while meeting Internet and Kubernetes naming standards.
Kubernetes requires that hostnames are composed of a sequence of labels concatenated with dots. For example, “en.wikipedia.org” is a hostname. Each label must be from 1 to 63 characters long. The entire hostname, including the delimiting dots, has a maximum of 253 ASCII characters.
The Internet standards (RFCs) for protocols specify that labels may contain only the ASCII letters a through z (in lower case), the digits 0 through 9, and the hyphen-minus character ('-').
Add the same NEW_HOSTNAME value to /etc/hosts on your VM for the localhost entry. Example:
127.0.0.1 localhost NEW_HOSTNAME
Verify that your first worker node meets the VM requirements, as described in step 1.
Confirm that the required ports are open for communications, as described in step 2.
Open your hypervisor and set up the VM in the same manner as for the master node.
Make a note of the private IP address you assign to the worker node. You need it for later installation steps.
Verify the worker node is ready for installation. Fix any errors indicated before installing the NetQ software.
cumulus@hostname:~$ sudo opta-check-cloud
Repeat steps 8 through 11 for each additional worker node in your cluster.
Install and activate the NetQ software using the CLI:
Run the following command on your master node to initialize the cluster. Copy the output of the command to use on your worker nodes:
cumulus@<hostname>:~$ netq install cluster master-init
Please run the following command on all worker nodes:
netq install cluster worker-init c3NoLXJzYSBBQUFBQjNOemFDMXljMkVBQUFBREFRQUJBQUFCQVFDM2NjTTZPdVVUWWJ5c2Q3NlJ4SHdseHBsOHQ4N2VMRWVGR05LSWFWVnVNcy94OEE4RFNMQVhKOHVKRjVLUXBnVjdKM2lnMGJpL2hDMVhmSVVjU3l3ZmhvVDVZM3dQN1oySVZVT29ZTi8vR1lOek5nVlNocWZQMDNDRW0xNnNmSzVvUWRQTzQzRFhxQ3NjbndIT3dwZmhRYy9MWTU1a
Run the netq install cluster worker-init <ssh-key> on each of your worker nodes.
Run the following command on your NetQ cloud appliance with the config-key obtained from the email you received from NVIDIA titled NetQ Access Link. You can also obtain the configuration key through the NetQ UI. Use the IP addresses of your worker nodes and the HA cluster virtual IP address (VIP).
The HA cluster virtual IP must be allocated from the same subnet used for your master and worker nodes.
You can specify the IP address instead of the interface name here: use ip-addr <IP address> in place of interface <ifname> above.
If you have changed the IP address or hostname of the NetQ OPTA 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 install CLI on the appliance. This example uses interface eth0. Replace this with your updated IP address, hostname or interface using the interface or ip-addr option.
If this step fails for any reason, you can run netq bootstrap reset and then try again.
Consider the following for container environments, and make adjustments as needed.
Calico Networking
NetQ overrides the Calico default address range and changes it to 10.244.0.0/16. To modify this range, use the netq install opta command, specifying the default address range with the pod-ip-range option. For example:
The default Docker bridge interface is disabled in NetQ. If you need to reenable the interface, contact support.

After NetQ is installed, you can log in to NetQ from your browser.
Install On-switch OPTA
Configure the On-switch OPTA
Instead of installing a dedicated OPTA VM, you can enable the OPTA service on one or more switches in your environment to send data to the NetQ Cloud.
On-switch OPTA (on-premises telemetry aggregator) is intended for use in small NetQ Cloud deployments where a dedicated OPTA VM might not be necessary. If you need help assessing the correct OPTA configuration for your deployment, contact your NVIDIA sales team.
To configure a switch for OPTA functionality, install the netq-opta package. To obtain the package, add or uncomment the NetQ repository in /etc/apt/sources.list as needed:
cumulus@switch:~$ sudo nano /etc/apt/sources.list
...
deb https://apps3.cumulusnetworks.com/repos/deb CumulusLinux-4 netq-4.9
...
You can use the deb https://apps3.cumulusnetworks.com/repos/deb CumulusLinux-4 netq-latest repository if you want to always retrieve the latest posted version of NetQ.
After adding the repository, install the netq-opta package with the following commands:
After the netq-opta package is installed, add your OPTA configuration key. Run the following command with the config-key obtained from the email you received from NVIDIA titled NetQ Access Link. You can also obtain the configuration key through the NetQ UI in the premises management configuration.
After adding the config-key, restart the OPTA service:
sudo netq config restart opta
Connect NetQ Agents to the OPTA Service
The final step is configuring NetQ Agents to connect to the OPTA service. To configure the agent on a switch to connect locally to the OPTA service running on that switch, configure the agent to connect to localhost with the following command:
To configure the agent on a switch to connect to the OPTA service on another switch in your network, configure the agent to connect to the IP address of the switch running the OPTA service:
You cannot enable the LCM executor on more than one switch running the OPTA service.
You cannot decommission a switch from the NetQ UI while it is running the OPTA service. To decommission a switch running the OPTA service, stop services with the sudo netq config stop opta and sudo netq config stop lcm-executor commands. Then reconfigure any NetQ Agents to connect to a different OPTA before decommissioning the switch.
You cannot upgrade a switch using NetQ LCM if it is the only switch in your network running the OPTA service with the LCM executor enabled. To upgrade the switch, reconfigure OPTA and the LCM executor on a different switch and redirect NetQ Agents to the new OPTA before upgrading the original switch.
Disable the LCM Executor
Disable the LCM executor by stopping it, then restarting the OPTA service:
Installing NetQ telemetry agents on your hosts with NVIDIA ConnectX adapters and NVIDIA BlueField data processing units (DPUs) allows you to track inventory data and statistics across devices. The DOCA Telemetry Service (DTS) is the agent that runs on hosts and DPUs to collect data.
Install DTS on ConnectX Hosts
To install and configure the DOCA Telemetry Service container on a host with ConnectX adapters, perform the following steps:
Obtain the DTS container image path from the NGC catalog. Select Get Container, then View all tags. Copy the 1.16.1-doca2.6.0-host image path.
Initialize the DTS container with Docker on the host. Use the image path obtained in the previous step for the DTS_IMAGE variable and configure the IP address of your NetQ server for the -i option:
The Prometheus adapter pod in NetQ collects statistics from ConnectX adapters in your network. The default scrape interval is every minute. If you want to change the frequency of the scrape interval, make your adjustments, then restart the netq-prom-adapter pod to begin collecting data with the updated parameters:
Log in to your NetQ VM via SSH.
Edit the Prometheus ConfigMap with the kubectl edit cm prometheus-config command.
Edit the scrape_interval parameter.
Retrieve the current pod name with the kubectl get pods | grep netq-prom command:
kubectl delete pod netq-prom-adapter-ffd9b874d-hxhbz
Install DTS on DPUs
To install and configure the DOCA Telemetry Service (DTS) container on a DPU, perform the following steps:
Obtain the DTS container image path from the NGC catalog. Select Get Container, then View all tags. Copy the 1.15.5-doca2.5.0 image path.
Retrieve the container yaml configuration file onto the host. Use the path specified in the Adjusting the .yaml Configuration section in the NGC instructions. Copy it to /etc/kubelet.d/doca_telemetry_standalone.yaml:
Edit the image in both the containers and initContainers sections of the /etc/kubelet.d/doca_telemetry_standalone.yaml file to set the container image path retrieved in step 1.
Edit the command in the initContainers section of the /etc/kubelet.d/doca_telemetry_standalone.yaml file to set the DTS_CONFIG_DIR parameter to inventory_netq. Configure the fluent forwarding -i option to your NetQ server IP address and the -p option to 30001:
When you first log in to the NetQ UI as part of an on-premises deployment, your browser will display a warning indicating that the default certificate is not trusted. You can avoid this warning by installing your own, custom-signed certificate using the steps outlined on this page. The self-signed certificate is sufficient for non-production environments or cloud deployments.
If you already have a certificate installed and want to change or update it, run the kubectl delete secret netq-gui-ingress-tls [name] --namespace default command before following the steps outlined in this section. After making your updates, restart nginx with the kubectl delete pod -l app.kubernetes.io/name=ingress-nginx --namespace ingress-nginx command.
You need the following items to perform the certificate installation:
A valid X509 certificate, containing a Subject Alternative Name (SAN) attribute.
A private key file for the certificate.
A DNS record name configured to access the NetQ UI.
The FQDN should match the common name of the certificate. If you use a wild card in the common name — for example, if the common name of the certificate is *.example.com — then the NetQ telemetry server should reside on a subdomain of that domain, accessible via a URL like netq.example.com.
A functioning and healthy NetQ instance.
You can verify this by running the netq show opta-health command.
Install a Certificate using the NetQ CLI
Log in to the NetQ VM via SSH and copy your certificate and key file there.
Generate a Kubernetes secret called netq-gui-ingress-tls:
cumulus@netq-ts:~$ kubectl create secret tls netq-gui-ingress-tls \
--namespace default \
--key <name of your key file>.key \
--cert <name of your cert file>.crt
Verify that you created the secret successfully:
cumulus@netq-ts:~$ kubectl get secret
NAME TYPE DATA AGE
netq-gui-ingress-tls kubernetes.io/tls 2 5s
Update the ingress rule file to install self-signed certificates.
Your custom certificate should now be working. Verify this by opening the NetQ UI at https://<your-hostname-or-ipaddr> in your browser.
Update Cloud Activation Key
NVIDIA provides a cloud activation key when you set up your premises. You use the cloud activation key (called the config-key) to access the cloud services. Note that these authorization keys are different from the ones you use to configure the CLI.
On occasion, 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 NVIDIA.
Update the activation key using the NetQ CLI:
Run the following command on your master NetQ VM replacing text-opta-key with your new key.
This section describes how to upgrade from your current installation to NetQ 4.9. Refer to the release notes before you upgrade.
You must upgrade your NetQ on-premises or cloud virtual machines. Upgrading NetQ Agents is optional, but 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.
Follow these steps to upgrade your on-premises or cloud deployment. Note that these steps are sequential; you must upgrade your NetQ virtual machine before you upgrade the NetQ Agents.
This page describes how to upgrade your NetQ virtual machines. Note that the upgrade instructions vary depending on NetQ version you’re currently running.
For deployments running:
4.8.0, 4.7.0, 4.6.0, or 4.5.0: upgrade directly to NetQ 4.9.0 by following the steps on this page
If the output of this command displays errors or returns an empty response, you will not be able to upgrade NetQ. Try waiting and then re-run the command. If after several attempts the command continues to fail, reset the NetQ server with netq bootstrap reset keep-db and perform a fresh installation of the tarball with the appropriate netq install command for your deployment type.
Back up your NetQ data. This is an optional step for on-premises deployments. NVIDIA automatically creates backups for NetQ cloud deployments.
Update NetQ Debian Packages
Update /etc/apt/sources.list.d/cumulus-netq.list to netq-4.9:
cat /etc/apt/sources.list.d/cumulus-netq.list
deb [arch=amd64] https://apps3.cumulusnetworks.com/repos/deb focal netq-4.9
Update the NetQ debian packages. In cluster deployments, update the packages on the master and all worker nodes.
Select the relevant software for your hypervisor: If you are upgrading NetQ Platform software for a NetQ on-premises VM, select NetQ SW 4.9 Appliance to download the NetQ-4.9.0.tgz file. If you are upgrading NetQ software for a NetQ cloud VM, select NetQ SW 4.9 Appliance Cloud to download the NetQ-4.9.0-opta.tgz file.
If prompted, read the license agreement and proceed with the download.
For enterprise customers, if you do not see a link to the NVIDIA Licensing Portal on the NVIDIA Application Hub, contact NVIDIA support.
Copy the tarball to the /mnt/installables/ directory on your NetQ VM.
Run the Upgrade
Perform the following steps using the cumulus user account.
Pre-installation Checks
Verify the following items before upgrading NetQ.
Confirm your VM is configured with 16 vCPUs. If your VM is configured with fewer than 16 vCPUs, power off your VM, reconfigure your hypervisor to allocate 16 vCPUs, then power the VM on before proceeding. For cluster deployments, verify these requirements on each node in the cluster.
Check if there is sufficient disk space:
cumulus@<hostname>:~$ df -h /
Filesystem Size Used Avail Use% Mounted on
/dev/sda1 248G 70G 179G 28% /
cumulus@netq-appliance:~$
NVIDIA recommends proceeding with the installation only if the Use% is less than 70%. You can delete previous software tarballs in the /mnt/installables/ directory to regain some space. If you cannot decrease disk usage to under 70%, contact the NVIDIA support team.
Confirm that the NetQ CLI is properly configured. The netq show agents command should complete successfully and display agent status.
If you are upgrading a cluster deployment to NetQ 4.9.0, you must open TCP port 36443 for Kubernetes control plane operations.
Run the following command to ensure that the NetQ version is consistent between the netq-agent package, the netq-apps package, and the tarball you downloaded in the previous section:
cumulus@<hostname>:~$ dpkg -l | grep netq
ii netq-agent 4.9.0-ub20.04u45~1710409093.ea9740d7c amd64 Cumulus NetQ Telemetry Agent for Ubuntu
ii netq-apps 4.9.0-ub20.04u45~1710409093.ea9740d7c amd64 Cumulus NetQ Fabric Validation Application for Ubuntu
Upgrade Using the NetQ CLI
Run the appropriate commands for your deployment type:
If this step fails for any reason, run the netq bootstrap reset keep-db command and perform a fresh installation of the tarball with the netq install standalone full command.
Run the netq upgrade command, specifying the current version’s tarball and your cluster’s virtual IP address. The virtual IP address must be allocated from the same subnet used for your master and worker nodes.
If you are upgrading from a NetQ 4.8 high availability, on-premises cluster with a virtual IP address, you do not need to include the cluster-vip option in the upgrade command. Specifying a virtual IP address that is different from the virtual IP address used during the installation process will cause the upgrade to fail.
If this step fails for any reason, run the netq bootstrap reset keep-db command and perform a fresh installation of the tarball with the netq install cluster full command.
If this step fails for any reason, run the netq bootstrap reset keep-db command and perform a fresh installation of the tarball with the netq install opta standalone full command.
Run the netq upgrade command, specifying the current version’s tarball and your cluster’s virtual IP address. The virtual IP address must be allocated from the same subnet used for your master and worker nodes.
If this step fails for any reason, run the netq bootstrap reset keep-db command and perform a fresh installation of the tarball with the netq install opta cluster full command.
NetQ accounts are assigned one of two roles: admin or user. Accounts with admin privileges can perform the same actions as user accounts. Additionally, admins can access a management dashboard in the UI by expanding the Menu on the NetQ dashboard, then selecting Management.
From this dashboard, admins can:
Create, edit, and delete NetQ accounts
Manage login policies, including SSO and LDAP authentication
Review account activity
Create, edit, and delete system events, channels, and notifications
Manage premises
Schedule network traces and validations
Manage switches' lifecycles
The following image displays the management dashboard. Accounts with user privileges cannot perform the functions described above and do not have access to the management dashboard.
Sign in to NetQ as an admin to view and manage accounts. If you want to change individual preferences, visit Set User Preferences.
Navigate to the NetQ management dashboard to complete the tasks outlined in this section. To get there, expand the Menu on the NetQ dashboard and select Management.
Add an Account
This section outlines the steps to add a local user account. To add an LDAP account, refer to LDAP Authentication.
To create a new account:
On the User Accounts card, select Manage to open a table listing all accounts.
Above the table, select Add to add an account.
Enter the fields and select Save.
Be especially careful entering the email address; 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.
Edit an Account
As an admin, you can:
Edit the first or last name associated with an account
Reset an account’s password
Change an account’s role (user or admin)
You cannot edit the email address associated with an account, because this is the identifier the system uses for authentication. If you need to change an email address, delete the account and create a new one.
To edit an account:
On the User Accounts card, select Manage to open a table listing all accounts.
Select the account you’d like to edit. Above the table, click Edit to edit the account’s information.
Reset an Admin Password
If your account is assigned an admin role, reset your password by restoring the default password, then changing the password:
Run the following command on your on-premises server’s CLI:
Click Forgot Password? and enter an email address. Look for a message with the subject NetQ Password Reset Link from netq-sre@cumulusnetworks.com.
Select the link in the email and follow the instructions to create a new password.
Delete an Account
To delete one or more accounts:
On the User Accounts card, select Manage to open a table listing all accounts.
Select one or more accounts. Above the table, click Delete to delete the selected account(s).
View Account Activity
Administrators can view account activity in the activity log. To get there, expand the Menu and select Activity log. Use the controls above the table to filter or export the data.
Manage Login Policies
Administrators can configure a session expiration time and the number of times users can refresh before requiring them to log in again to NetQ.
To configure these login policies:
On the Login Management card, select Manage.
Select how long an account can be logged in before requiring a user to log in again:
Click Update to save the changes.
The Login Management card reflects the updated configuration.
Configure Premises
The NetQ management dashboard lets you configure a single NetQ UI and CLI for monitoring data from multiple premises. This means you do not need to log in to each premises individually to view the data.
Configure Multiple Premises
There are two ways to implement a multi-site, on-premises deployment: (1) as a full deployment at the primary premises and each of the external premises or (2) as a full deployment at the primary premises with smaller deployments at the secondary premises.
The primary premises is called OPID0 by default in the UI.
Full NetQ Deployment at Each Premises
In this implementation, there is a NetQ appliance or VM running the NetQ software with a database. Each premises operates independently as an external premises, with its own NetQ UI and CLI. The NetQ appliance or VM at one of the deployments acts as the primary premises. A list of external premises is stored with the primary deployment.
To configure a single UI to monitor multiple premises:
From the UI of the primary premises (OPID0), select the Premises dropdown in the top-right corner of the screen.
Select Manage premises, then select the External premises tab.
Select Add external premises.
Enter the IP address for the external server, your username, and password. The username and password are the same credentials used to log in to the UI for the external server. Select Next
Select the premises you want to connect, then click Finish.
You can also reduce the number of premises that can be displayed in the UI by hovering over a deployment and selecting Delete.
To view the premises you just added, return to the home workbench and select the Premises dropdown in the top-right corner of the screen. Alternately, run the netq config show cli premises command.
Full NetQ Deployment at Primary Premises and Smaller Deployments at Secondary Premises
In this implementation, there is a NetQ appliance or VM at one of the deployments acting as the primary premises for the other deployments. The primary premises runs the NetQ software (including the NetQ UI and CLI) and houses the database. All other deployments are secondary premises; they run the NetQ cloud software and send their data to the primary premises for storage and processing. A list of these secondary premises is stored with the primary deployment.
After the multiple premises are configured, you can view this list of premises in the NetQ UI at the primary premises, change the name of premises on the list, and delete premises from the list.
In this deployment model, the data is stored and can be viewed only from the NetQ UI at the primary premises.
The primary NetQ premises must be installed and operational before the secondary premises can be added.
To create and add secondary premises:
In the workbench header, select the Premises dropdown.
Click Manage premises. Your primary premises (OPID0) is shown by default.
Click Add premises.
Enter the name of a secondary premises you’d like to add, then click Done.
From the confirmation dialog, select View config key.
Click the copy icon, then save the key to a safe place, or click e-mail to send it to yourself or others. Then click Confirm activation.
To view the premises you just added, return to the home workbench and select the Premises dropdown at the top-right corner of the screen. Alternately, run the netq config show cli premises command.
Rename a Premises
To rename an existing premises:
In the workbench header, select the Premises dropdown, then Manage premises.
Select a premises to rename, then click Edit.
Enter the new name for the premises, then click Done.
(Optional) Reconfigure the NetQ CLI by generating new AuthKeys. You must complete this step after renaming a premises for the CLI to be functional.
The following sections describe how to back up and restore your NetQ data and VMs for on-premises deployments. Cloud deployments are backed up automatically.
You must run backup and restore scripts with sudo privileges.
In the directory you copied the vm-backuprestore.sh script, run:
cumulus@netq-appliance:~$ sudo ./vm-backuprestore.sh --backup
[sudo] password for cumulus:

Restore Your NetQ Data
Restore NetQ data with the backup file you created in the steps above. 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.
Run the restore script, referencing the directory where the backup file resides.
If you restore NetQ data to a server with an IP address that is different from the one used to back up the data, you must reconfigure the agents on each switch as a final step.
cumulus@netq-appliance:~$ sudo vm-backuprestore.sh --restore --backupfile /home/cumulus/backup-netq-standalone-onprem-4.4.0-2023-02-06_12_37_29_UTC.tar

Post-installation Configurations
This section describes the various integrations you can configure after installing NetQ.
As an administrator, you can 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. With the RBAC integration, LDAP handles account authentication and your directory service (such as Microsoft Active Directory, Kerberos, OpenLDAP, and Red Hat Directory Service). A copy of each account from LDAP is stored in the local NetQ database.
Integrating with an LDAP server does not prevent you from configuring local accounts (stored and managed in the NetQ database) as well.
Get Started
LDAP integration requires information about how to connect to your LDAP server, the type of authentication you plan to use, bind credentials, and, optionally, search attributes.
Provide Your LDAP Server Information
To connect to your LDAP server, you need the URI and bind credentials. The URI identifies the location of the LDAP server. It comprises 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 you use port 389 for connection over TCP or UDP. In production environments, you deploy a secure connection with SSL. 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
There are two types of user authentication: 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. You define the distinguished name (DN) 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 get sent as clear text. Only users with these credentials can 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
You need the following two attributes 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, you can use the user ID (UID) or email address with OpenLDAP, whereas you might use the sAMAccountName 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. You specify the data to search for 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 could be {userIdAttribute}={userId}.
Create an LDAP Configuration
You can configure one LDAP server per bind DN (distinguished name). After you configure LDAP, you can verify the connectivity and save the configuration.
To create an LDAP configuration:
Expand the Menu and select Management.
Locate the LDAP Server Info card, and click Configure LDAP.
Fill out the LDAP server configuration form according to your particular configuration.
Click Save to complete the configuration, or click Cancel to discard the configuration.
The LDAP configuration cannot be changed after it is 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
This section lists a variety of example configurations. 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.

Add LDAP Users to NetQ
Click Menu and select Management.
Locate the User Accounts card, and click Manage.
From the User accounts tab, select Add user above the table.
Select LDAP User, then enter the user’s ID.
Enter your administrator password, then select Search.
If the user is found, the email address, first, and last name fields are automatically populated. 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 need to edit the mapping file.
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.
Expand the Menu and select Management.
Locate the User Accounts card, and click Manage.
Select the user(s) you want to remove, then select Delete.
If you delete an LDAP user in LDAP it is not automatically deleted from NetQ; however, the login credentials for these LDAP users stop working immediately.
Integrate NetQ with Grafana
Switches collect statistics about the performance of their interfaces. The NetQ Agent on each switch collects these statistics every 15 seconds and then sends them to your NetQ appliance or virtual machine.
NetQ collects statistics for physical interfaces; it does not collect statistics for virtual interfaces, such as bonds, bridges, and VXLANs.
NetQ displays:
Transmit with tx_ prefix: bytes, carrier, colls, drop, errs, packets
Receive with rx_ prefix: bytes, drop, errs, frame, multicast, packets
You can use Grafana, 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.
The Grafana plugin comes unsigned. Before you can install it, you need to update the grafana.ini file then restart the Grafana service:
Edit the /etc/grafana/grafana.ini file and add allow_loading_unsigned_plugins = netq-dashboard under plugins:
Cumulus in the Cloud (CITC): plugin.air.netq.nvidia.com
From the Module dropdown, select procdevstats.
Enter your credentials (the ones used to log in).
For NetQ 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.
If multiple premises are configured with the same name, then the first listed premises is displayed.
Select Save & Test.
Create Your NetQ Dashboard
After you configure the data source, you can create a customizable dashboard with transmit and receive statistics.
Create a Dashboard
Click to open a blank dashboard.
Click (Dashboard Settings) at the top of the dashboard.
Add Variables
Click Variables.
In the Name field, enter hostname.

Now that the variables are defined, click to return to the new dashboard.
Click Add Query.
From the Query source list, select Net-Q.
Select the interface statistic you want to view from the Metric list.
Click the General icon.
From the Repeat list, select hostname.
Set any other parameters around how to display the data.
Return to the dashboard.
Select one or more hostnames from the hostname list.
Select one or more interface names from the ifname list.
Select one or more metrics to display for these hostnames and interfaces from the metrics list.
The following example shows a dashboard with two hostnames, two interfaces, and one metric selected. The more values you select from the variable options, the more charts appear on your dashboard.
Analyze the Data
After you have configured the dashboard, you can start analyzing the data. You can explore the data by modifying the viewing parameters in one of several ways using the dashboard tool set:
Select a different time period for the data by clicking the forward or back arrows. The default time range is dependent on the width of your browser window.
Zoom in on the dashboard by clicking the magnifying glass.
Manually refresh the dashboard data, or set an automatic refresh rate for the dashboard from the down arrow.
Add additional panels.
Click any chart title to edit or remove it from the dashboard.
Rename the dashboard by clicking the cog wheel and entering the new name.
SSO Authentication
You can integrate your NetQ Cloud deployment with a Microsoft Azure Active Directory (AD) or Google Cloud authentication server to support single sign-on (SSO) to NetQ. NetQ supports integration with SAML (Security Assertion Markup Language), OAuth (Open Authorization), and multi-factor authentication (MFA). Only one SSO configuration can be configured at a time.
You can create local accounts with default access roles by enabling SSO. After enabling SSO, users logging in for the first time can sign up for SSO through the NetQ login screen or with a link provided by an admin.
Add SSO Configuration and Accounts
To integrate your authentication server:
Expand the Menu and select Management.
Locate the SSO Configuration card and select Manage.
Select either SAML or OpenID (which uses OAuth with OpenID Connect).
Specify the parameters:
You need several pieces of data from your Microsoft Azure or Google account and authentication server to complete the integration.
SSO Organization is typically a company’s name or a department. The name entered in this field will appear in the SSO signup URL.
Role (either user or admin) is automatically assigned when the account is initalized via SSO login.
Name is a unique name for the SSO configuration.
Client ID is the identifier for your resource server.
Client Secret is the secret key for your resource server.
Authorization Endpoint is the URL of the authorization application.
Token Endpoint is the URL of the authorization token.
Select Test to verify the configuration and ensure that you can log in. If it is not working, you are logged out. Check your specification and retest the configuration until it is working properly.
Select Close. The card reflects the configuration:
To require users to log in using this SSO configuration, select Change under the “Disabled” status and confirm. The card updates to reflect that SSO is enabled.
After an admin has configured and enabled SSO, users logging in for the first time can sign up for SSO.

dpkg-query: no packages found matching netq-agent
cumulus@switch:~$ dpkg-query -l netq-apps
dpkg-query: no packages found matching netq-apps
Use the yum remove command to remove the NetQ agent or CLI package from a RHEL7 or CentOS host:
Verify the removal of the packages from the switch:
cumulus@switch:~$ dpkg-query -l netq-agent
dpkg-query: no packages found matching netq-agent
cumulus@switch:~$ dpkg-query -l netq-apps
dpkg-query: no packages found matching netq-apps
Delete the virtual machine according to the usual VMware or KVM practice.
Delete a virtual machine from the host computer using one of the following methods:
Right-click the name of the virtual machine in the Favorites list, then select Delete from Disk.
Select the virtual machine and choose VM > Delete from disk.
Delete a virtual machine from the host computer using one of the following methods:
Run virsch undefine <vm-domain> --remove-all-storage
Run virsh undefine <vm-domain> --wipe-storage
Manage Users
As an admin, you can manage users and authentication settings from the NetQ management dashboard.
Lifecycle management displays an inventory of switches that are available for software installation or upgrade through NetQ. From the inventory list, you can assign access profiles and roles to switches, and select switches for software installation and upgrades. You can also decommission switches, which removes them from the NetQ database.
If you manage a switch using an in-band network interface, ensure that you have configured the agent before performing any LCM operations on the switch.
View the LCM Switch Inventory
Expand the Menu, then select Manage switches. From the LCM dashboard, select the Switch management tab. The Switches card displays the number of switches that NetQ discovered and the network OS versions that are running on those switches:
To view a table of all discovered switches and their attributes, select Manage on the Switches card.
If you have more than one network OS version running on your switches, you can click a version segment on the Switches card chart to open a list of switches filtered by that version.
To view a list of all switches discovered by lifecycle management, run:
netq lcm show switches
[cl-version <text-cumulus-linux-version>]
[netq-version <text-netq-version>]
[json]
Use the version options to display switches with a given OS version. For additional details, refer to the command line reference.
The table of switches is the starting point for network OS upgrades or NetQ installations and upgrades. If the switches you want to upgrade are not present in the list, you can:
Verify the missing switches are reachable using ping
Run a switch discovery, which locates all switches running Cumulus Linux in your network’s fabric
Verify the NetQ Agent is fresh and running version 4.1.0 or later for switches that already have the agent installed (click Menu, then click Agents or run netq show agents)
A switch discovery searches your network for all Cumulus Linux switches (with and without NetQ currently installed) and determines the versions of Cumulus Linux and NetQ installed. These results can be used to install or upgrade Cumulus Linux and NetQ on all discovered switches in a single procedure.
If you intend to upgrade your switches, generate AuthKeys using the UI. Copy the access key and secret key to an accessible location. You will enter the AuthKeys later on in this process.
To discover switches running Cumulus Linux:
Click Devices in the workbench header, then click Manage switches.
On the Switches card, click Discover.
Enter a name for the scan.
Choose whether you want to look for switches by entering IP address ranges or import switches using a comma-separated values (CSV) file.
If you do not have a switch listing, then you can manually add the address ranges where your switches are located in the network. This has the advantage of catching switches that might have been missed in a file.
A maximum of 50 addresses can be included in an address range. If necessary, break the range into smaller ranges.
To discover switches using address ranges:
Enter an IP address range in the IP Range field.
Ranges can be contiguous, for example 192.168.0.24-64, or non-contiguous, for example 192.168.0.24-64,128-190,235, but they must be contained within a single subnet.
Optionally, enter another IP address range (in a different subnet) by clicking .
For example, 198.51.100.0-128 or 198.51.100.0-128,190,200-253.
Add additional ranges as needed. Click to remove a range.
If you decide to use a CSV file instead, the ranges you entered will remain if you return to using IP ranges again.
To import switches through a CSV file:
Click Browse.
Select the CSV file containing the list of switches.
The CSV file must include a header containing hostname, ip, and port. They can be in any order you like, but the data must match that order. For example, a CSV file that represents the Cumulus reference topology could look like this:
or this:
You must have an IP address in your file, but the hostname is optional. If the port is blank, NetQ uses switch port 22 by default.
Click Remove if you decide to use a different file or want to use IP address ranges instead. If you entered ranges before selecting the CSV file option, they remain.
Select an access profile from the dropdown menu. If you use Netq-Default you will see a message requesting that you create or update your credentials.
Click Next.
When the network discovery is complete, NetQ presents the number of Cumulus Linux switches it found. Each switch can be in one of the following categories:
Discovered without NetQ: Switches found without NetQ installed
Discovered with NetQ: Switches found with some version of NetQ installed
Discovered but rotten: Switches found that are unreachable
Incorrect credentials: Switches found that are unreachable because the provided access credentials do not match those for the switches
OS not supported: Switches found that are running a Cumulus Linux version not supported by LCM upgrades
Not discovered: IP addresses which did not have an associated Cumulus Linux switch
If the discovery process does not find any switches for a particular category, then it does not display that category.
After performing a switch discovery, you can install or upgrade Cumulus Linux and NetQ.
Use the netq lcm discover command, specifying a single IP address, a range of IP addresses where your switches are located in the network, or a CSV file containing the IP address.
You must also specify the access profile ID, which you can obtain with the netq lcm show credentials command.
cumulus@switch:~$ netq lcm discover ip-range 192.168.0.15 profile_id credential_profile_d9e875bd2e6784617b304c20090ce28ff2bb46a4b9bf23cda98f1bdf911285c9
NetQ Discovery Started with job id: job_scan_9ea69d30-e86e-11ee-b32d-71890ec96f40
When the network discovery is complete, run netq lcm show discovery-job and include the job ID which you obtained from the previous command. If you do not specify a job ID, the output includes a list of all job IDs from all discovery jobs.
cumulus@switch:~$ netq lcm show discovery-job job_scan_9ea69d30-e86e-11ee-b32d-71890ec96f40

NetQ presents the number of Cumulus Linux switches it has found. The output displays their discovery status, which can be one of the following:
Discovered without NetQ: Switches found without NetQ installed
Discovered with NetQ: Switches found with some version of NetQ installed
Discovered but Rotten: Switches found that are unreachable
Incorrect Credentials: Switches found that are unreachable because the provided access credentials do not match those for the switches
OS not Supported: Switches found that are running Cumulus Linux version not supported by the LCM upgrade feature
Not Discovered: IP addresses which did not have an associated Cumulus Linux switch
After performing a switch discovery, you can install or upgrade Cumulus Linux and NetQ.
Role Management
You can assign switches one of four roles: superspine, spine, leaf, and exit.
Switch roles identify switch dependencies and determine the order in which switches are upgraded. The upgrade process begins with switches assigned the superspine role, then continues with the spine switches, leaf switches, exit switches, and finally, switches with no role assigned. Upgrades for all switches with a given role must be successful before the upgrade proceeds to the switches with the closest dependent role.
Role assignment is optional, but recommended. Assigning roles can prevent switches from becoming unreachable due to dependencies between switches or single attachments. Additionally, when you deploy MLAG pairs, assigned roles avoid upgrade conflicts.
Assign Roles to Switches
On the Switches card, click Manage.
Select one switch or multiple switches to assign to the same role.
Above the table, select Assign role.
Select the role (superspine, leaf, spine, or exit) 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). To return to the full list of switches, click All.
Continue selecting switches and assigning roles until most or all switches have roles assigned.
To assign multiple switches to the same role, separate the hostnames with commas (no spaces). This example configures leaf01 through leaf04 switches with the leaf role:
netq lcm add role leaf switches leaf01,leaf02,leaf03,leaf04
To view all switch roles, run:
netq lcm show switches [version <text-cumulus-linux-version>] [json]
Use the version option to only show switches with a given network OS version, X.Y.Z.
The Role column displays assigned roles:
cumulus@switch:~$ netq lcm show switches

Reassign Roles to Switches
On the Switches card, click Manage.
Select the switches with the incorrect role from the list.
Click Assign role.
Select the correct role. To leave a switch unassigned, select No Role.
Click Assign.
You use the same command to both assign a role and change a role.
For a single switch, run:
netq lcm add role exit switches border01
To assign multiple switches to the same role, separate the hostnames with commas (no spaces). For example:
cumulus@switch:~$ netq lcm add role exit switches border01,border02
Host a ZTP Script with NetQ
You can host a Zero Touch Provisioning (ZTP) script on your NetQ VM to provision switches running Cumulus Linux. To host a ZTP script, copy the script to your NetQ server and reference the path you copied to in the netq lcm add ztp-script CLI command:
cumulus@netq-server:~$ netq lcm add ztp-script /home/cumulus/ztp.sh
ZTP script ztp.sh uploaded successfully and can be downloaded from http://10.10.10.10/lcm/asset/ztp.sh
cumulus@netq-server:~$
The output of the command will provide the URL to use in the DHCP server option 239 configuration to instruct switches to retrieve the script. If you would like to use your NetQ VM as a DHCP server, you can use the Kea DHCP server package, which is installed by default.
To list scripts that are currently added to NetQ along with their download URLs and script identification numbers, use the netq lcm show ztp-scripts command. You can remove ZTP scripts from NetQ with the netq lcm del ztp-script <text-ztp-script-id> command.
Decommissioning the switch or host removes information about the switch or host from the NetQ database. When the NetQ Agent restarts at a later date, it sends a connection request back to the database, so NetQ can monitor the switch or host again.
From the LCM dashboard, navigate to the Switch management tab.
On the Switches card, select Manage.
Select the devices to decommission, then select Decommission switch above the table:
If you attempt to decommission a switch that is assigned a default, unmodified access profile, the process will fail. Create a unique access profile (or update the default with unique credentials), then attach the profile to the switch you want to decommission.
Confirm the devices you want to decommission.
Wait for the decommission process to complete, then select Done.
To decommission a switch or host:
On the given switch or host, stop and disable the NetQ Agent service:
You must have switch access credentials to install and upgrade software on a switch. These user authentication credentials are stored in NetQ as access profiles. The profiles must be applied to a switch before you can upgrade or install software.
Access Profiles
Authentication credentials are stored in access profiles which can be assigned to individual switches. You can create credentials with either basic (SSH username/password) or SSH (public/private key) authentication. This section describes how to create, edit, and delete access profiles. After you create a profile, attach it to individual switches so that you can perform upgrades on those switches.
By default, NVIDIA supplies an access profile called Netq-Default. You must create a new access profile or update the default profile with unique credentials to perform upgrades and other lifecycle management tasks.
You cannot delete the default profile.
Create Access Profiles
Expand the Menu and select Manage switches.
On the Access Profiles card, select Add profile.
Enter a name for the profile, then select the authentication method you want to use: SSH or Basic
The SSH user must have sudoer permission to configure switches when using the SSH key method. To provide sudo access to the SSH user on a switch, create a file in the /etc/sudoers.d/ directory with the following content. Replace <USER> with the SSH access profile username:
“<USER>” ALL=(ALL) NOPASSWD: ALL
Create a pair of SSH private and public keys on the NetQ appliance:
ssh-keygen -t rsa -C "<USER>"
When prompted, hit the enter/return key.
Copy the SSH public key to each switch that you want to upgrade using one of the following methods:
Manually copy the SSH public key to the /home/<USER>/.ssh/authorized_keys file on each switch, or
Run ssh-copy-id USER@<switch_ip> on the server where you generated the SSH key pair for each switch
Copy the SSH private key into the entry field:
For security, your private key is stored in an encrypted format, and only provided to internal processes while encrypted.
(Optional) To verify that the new profile is listed among available profiles, select View profiles from the Access Profiles card.
(Optional) Attach the profile to a switch so that you can perform upgrades.
Enter a username and password.
Click Create, then confirm.
(Optional) To verify that the new profile is listed among available profiles, select View profiles from the Access Profiles card.
(Optional) Attach the profile to a switch so that you can perform upgrades.
Specify a unique name for the configuration after profile_name.
The default credentials for Cumulus Linux have changed from cumulus/CumulusLinux! to cumulus/cumulus for releases 4.2 and later. For details, read Cumulus Linux User Accounts.
To configure SSH authentication using a public/private key:
You must have sudoer permission to properly configure switches when using the SSH key method.
If the keys do not yet exist, create a pair of SSH private and public keys on the NetQ appliance.
ssh-keygen -t rsa -C "<USER>"
When prompted, hit the enter/return key.
Copy the SSH public key to each switch that you want to upgrade using one of the following methods:
Manually copy the SSH public key to the /home/<USER>/.ssh/authorized_keys file on each switch, or
Run ssh-copy-id USER@<switch_ip> on the server where you generated the SSH key pair for each switch
Add these credentials to the switch. Specify a unique name for the configuration after profile_name.
You cannot delete a profile that is currently attached to a switch. You must attach a different profile to the switch first. Note that you cannot delete the Netq-Default profile (but you can edit it).
On the Access Profiles card, select View profiles.
From the list of profiles, select Delete in the profile’s row.
The delete icon only appears next to custom profiles that are not attached to a switch.
Select Remove.
Run netq lcm show credentials. Identify the profiles you’d like to delete and copy their identifiers from the Profile ID column. The following example deletes the n-1000 profile:
cumulus@netq-server:~$ netq lcm show credentials

View Access Profiles
You can view the type of credentials used to access your switches in the NetQ UI. You can view the details of the credentials using the NetQ CLI.
Open the LCM dashboard.
On the Access Profiles card, select View profiles.
To view a list of access profiles and their associated credentials, run netq lcm show credentials.
If you use an SSH key for the credentials, the public key appears in the command output.
If you use a username and password for the credentials, the username appears in the command output with the password masked.
Attach an Access Profile to a Switch
NetQ uses access profiles to store user authentications credentials. After creating an access profile from your credentials, you can attach a profile to one or multiple switches.
Expand the Menu and select Manage switches. On the Switches card, select Manage.
The table displays a list of switches. The Access type column specifies whether the type of authentication is basic or SSH. The Profile name column displays the access profile that is assigned to the switch.
Select the switches to which you’d like to assign access profiles, then select Manage access profile above the table:
Select the profile from the list, then click Apply. If the profile you want to use isn’t listed, select Add new profile and follow the steps to create an access profile.
Select Ok on the confirmation dialog. The updated access profiles are now reflected in the Profile name column.
The command syntax to attach a profile to a switch is:
Run netq lcm show switches and verify the change in the credential profile column.
NetQ and Network OS Images
NetQ and network operating system images (Cumulus Linux and SONiC) are managed with LCM. This section explains how to check for missing images, upgrade images, and specify default images.
View and Upload Missing Images
You should upload images for each network OS and NetQ version currently installed in your inventory so you can support rolling back to a known good version should an installation or upgrade fail. If you have specified a default network OS and/or NetQ version, the NetQ UI also verifies that the necessary versions of the default image are available based on the known switch inventory, and if not, lists those that are missing.
To upload missing network OS images:
Expand the Menu and select Manage switches. Select the Image management tab.
On the Cumulus Linux Images card, select View # missing CL images to see which images you need.
If you have already specified a default image, you must click Manage and then Missing to see the missing images.
Select one or more of the missing images and take note of the version, ASIC vendor, and CPU architecture for each.
Download the network OS disk images (.bin files) from the NVIDIA Enterprise Support Portal. Log in to the portal and from the Downloads tab, select Switches and Gateways. Under Switch Software, click All downloads next to Cumulus Linux for Mellanox Switches. Select the current version and the target version, then click Show Downloads Path. Download the file.
In the UI, select Add image above the table.
Provide the .bin file from an external drive that matches the criteria for the selected image(s).
Click Import.
If the upload was unsuccessful, an Image Import Failed message appears. Close the dialog and try uploading the file again.
Click Done.
(Optional) Click the Uploaded tab to verify the image is in the repository.
Click Close to return to the LCM dashboard.
The Cumulus Linux Images card reflects the number of images you uploaded.
(Optional) Display a summary of Cumulus Linux images uploaded to the LCM repo on the NetQ appliance or VM:
netq lcm show cl-images
Download the network OS disk images (.bin files) from the NVIDIA Enterprise Support Portal. Log into the portal and from the Downloads tab, select Switches and Gateways. Under Switch Software, click All downloads next to Cumulus Linux for Mellanox Switches. Select the current version and the target version, then click Show Downloads Path. Download the file.
Upload the images to the LCM repository. The following example uses a Cumulus Linux 4.2.0 disk image.
Repeat step 2 for each image you need to upload to the LCM repository.
To upload missing NetQ images:
Expand the Menu and select Manage switches. Select the Image management tab.
On the NetQ Images card, select View # missing NetQ images to see which images you need.
If you have already specified a default image, you must click Manage and then Missing to see the missing images.
Select one or all of the missing images and make note of the OS version, CPU architecture, and image type. Remember that you need both netq-apps and netq-agent for NetQ to perform the installation or upgrade.
Download the NetQ Debian packages needed for upgrade from the NetQ repository, selecting the appropriate OS version and architecture. Place the files in an accessible part of your local network.
In the UI, click Add image above the table.
Provide the .deb file(s) from an external drive that matches the criteria for the selected image.
Click Import.
If the upload was unsuccessful, an Image Import Failed message appears. Close the dialog and try uploading the file again.
Click Done.
(Optional) Click the Uploaded tab to verify that the image is in the repository.
Click Close to return to the LCM dashboard.
The NetQ Images card reflects the number of images you uploaded.
(Optional) Display a summary of NetQ images uploaded to the LCM repo on the NetQ appliance or VM:
netq lcm show netq-images
Download the NetQ Debian packages needed for upgrade from the NetQ repository, selecting the appropriate version and hypervisor/platform. Place them in an accessible part of your local network.
Upload the images to the LCM repository. This example uploads the two packages (netq-agent and netq-apps) needed for NetQ version 4.4.0 for a NetQ appliance or VM running Ubuntu 18.04 with an x86 architecture.
To upload the network OS or NetQ images that you want to use for upgrade, first download the Cumulus Linux or SONiC disk images (.bin files) and NetQ Debian packages from the NVIDIA Enterprise Support Portal and NetQ repository, respectively. Place them in an accessible part of your local network.
If you are upgrading the network OS on switches with different ASIC vendors or CPU architectures, you need more than one image. For NetQ, you need both the netq-apps and netq-agent packages for each variant.
After obtaining the images, upload them to NetQ with the UI or CLI:
From the LCM dashboard, select the Image management tab.
Select Add image on the appropriate card:
Provide one or more images from an external drive.
Click Import.
Monitor the progress until it completes. Click Done.
Use the netq lcm add cl-image <text-cl-image-path> and netq lcm add netq-image <text-image-path> commands to upload the images. Run the relevant command for each image that needs to be uploaded.
Specifying a default upgrade version is optional, but recommended. You can assign a specific OS or NetQ version as the default version to use when installing or upgrading switches. The default is typically the newest version that you intend to install or upgrade on all, or the majority, of your switches. If necessary, you can override the default selection during the installation or upgrade process if an alternate version is needed for a given set of switches.
To specify a default version in the NetQ UI:
From the LCM dashboard, select the Image management tab.
Select Click here to set default x version on the relevant card.
Select the version you want to use as the default for switch upgrades.
Click Save. The default version is now displayed on the relevant Images card.
cumulus@switch:~$ netq lcm show default-version netq-images
Remove Images from Local Repository
After you upgrade all your switches beyond a particular release, you can remove images from the LCM repository to save space on the server. To remove images:
From the LCM dashboard, select the Image management tab.
Click Manage on the Cumulus Linux Images or NetQ Images card.
On the Uploaded tab, select the images you want to remove.
Click Delete.
To remove Cumulus Linux images, run:
netq lcm show cl-images [json]
netq lcm del cl-image <text-cl-image-id>
Lifecycle management lets you upgrade to the latest agent version on switches with an existing NetQ Agent. You can upgrade only the NetQ Agent or both the NetQ Agent and NetQ CLI simultaneously. You can run up to five jobs at the same time; however, a given switch can only appear in one running job at a time.
Prepare for a NetQ Agent Upgrade
Before you upgrade, make sure you have the appropriate files and credentials:
(Optional) Create an agent configuration profile, as described in the next section.
Agent Configuration Profiles
You can set up a configuration profile to indicate how you want NetQ configured when it is installed or upgraded on your Cumulus Linux switches. When you create a configuration profile, you can adjust the following agent settings:
The VRF the NetQ agent uses to communicate with the NetQ server
Whether WJH is enabled or disabled
The agent log level
The agent CPU limit
The default configuration profile, NetQ default config, is set up to run in the management VRF and provide info-level logging. Both WJH and CPU limiting are disabled.
Create a NetQ agent configuration profile with the netq lcm add netq-config command. If you manage the switch using an in-band interface, you must specify the interface name using the inband-interface option:
The steps below assume that a version of NetQ is already installed on your switches. If NetQ is not installed, run a switch discovery to find all Cumulus Linux switches with and without NetQ currently installed and perform the upgrade as part of the discovery workflow.
Expand the Menu and select Manage switches.
Locate the Switches card and click Manage. Select the switches you want to upgrade.
Click Upgrade NetQ above the table and follow the steps in the UI.
Verify that the number of switches selected for upgrade matches your expectation.
Enter a name for the upgrade job. The name can contain a maximum of 22 characters (including spaces).
Review each switch. If you’d like to change the agent configuration profile, click Change config, then select an alternate profile to apply to all selected switches. Alternately, you can apply different profiles to each switch by clicking the current profile and selecting an alternate profile.
Review the summary indicating the number of switches and the configuration profile to be used. If either is incorrect, click Back and review your selections.
Select the version of NetQ Agent for upgrade. If you have designated a default version, keep the Default selection. Otherwise, select an alternate version by clicking Custom and selecting it from the list.
By default, the NetQ Agent and CLI are upgraded on the selected switches. If you do not want to upgrade the NetQ CLI, click Advanced and change the selection to No.
NetQ performs several checks to eliminate preventable problems during the upgrade process. When all of the pre-checks pass, click Upgrade to initiate the upgrade.
To upgrade the NetQ Agent on one or more switches, run:
The following example creates a NetQ Agent upgrade job called upgrade-cl550-nq490. It upgrades the spine01 and spine02 switches with NetQ Agents version 4.9.0.
After starting the upgrade you can monitor the progress in the NetQ UI. Successful upgrades are indicated by a green . Failed upgrades display error messages indicating the cause of failure.
To view the progress of upgrade jobs using the CLI, run:
netq lcm show upgrade-jobs netq-image [json]
netq lcm show status <text-lcm-job-id> [json]
▼
Example netq lcm show upgrade-jobs
You can view the progress of one upgrade job at a time. This requires the job identifier.
The following example shows all upgrade jobs that are currently running or have completed, and then shows the status of the job with a job identifier of job_netq_install_7152a03a8c63c906631c3fb340d8f51e70c3ab508d69f3fdf5032eebad118cc7.

Upgrade Cumulus Linux
Lifecycle management (LCM) lets you upgrade Cumulus Linux on one or more switches in your network with the NetQ UI or the CLI. You do this by scheduling ‘upgrade jobs’ which upgrade Cumulus Linux on your switches. Each job can upgrade CL on up to 50 switches. NetQ upgrades the switches 5 at a time until all switches in the upgrade job are upgraded. You can schedule up to 5 upgrade jobs to run simultaneously.
You can upgrade switches running Cumulus Linux versions 5.0.0 to 5.8.0 that are managed with flat configuration files or with NVUE.
When you upgrade a switch that has not been configured using NVUE, LCM backs up and restores flat file configurations in Cumulus Linux. After you upgrade a switch that has been managed with flat files and subsequently run NVUE configuration commands, NVUE will overwrite the configuration restored by NetQ LCM. See Upgrading Cumulus Linux for additional information.
During the Cumulus Linux upgrade process, NetQ does not upgrade or reinstall packages that are not part of the Cumulus Linux image. For example, if you installed node_exporter packages on a switch, you must reinstall these packages after the upgrade is complete.
Prepare for a Cumulus Linux Upgrade
Before you upgrade, make sure you have the appropriate files and credentials:
If the NetQ Agent is already installed on the switches you’d like to upgrade, follow the steps below. If the NetQ Agent is not installed on the switches you’d like to upgrade, run a switch discovery to find all Cumulus Linux switches with and without NetQ currently installed and perform the CL upgrade as part of the discovery workflow.
Click Devices in any workbench header, then select Manage switches.
Locate the Switches card and click Manage.
Select the switches you want to upgrade.
Click Upgrade OS above the table.
Follow the steps in the UI. Create a name for the upgrade and review the switches that you selected to upgrade:
If you accidentally included a switch that you do not want to upgrade, hover over the switch information card and click Delete to remove it from the upgrade.
If the role is incorrect or missing, click Edit, then select a role for that switch from the dropdown. Click Cancel to discard the change.
By default, NetQ performs a roll back to the original Cumulus Linux version on any server which fails to upgrade. It also takes network snapshots before and after the upgrade.
You can exclude selected services and protocols from the snapshots by clicking them. Node and services must be included.
Click Next.
NetQ performs several checks to eliminate preventable problems during the upgrade process. When all of the pre-checks pass, click Preview.
NetQ directs you to a screen where you can review the upgrade. After reviewing, select Start upgrade and confirm.
Perform the upgrade using the netq lcm upgrade cl-image command, providing a name for the upgrade job, the Cumulus Linux and NetQ version, and a comma-separated list of the hostname(s) to be upgraded:
(Recommended) You can restore the previous version of Cumulus Linux if the upgrade job fails by adding the run-restore-on-failure option to the command.
cumulus@switch:~$ netq lcm upgrade cl-image name upgrade-540 cl-version 5.4.0 netq-version 4.9.0 hostnames spine01,spine02,leaf01,leaf02 order spine,leaf run-restore-on-failure
Pre-check Failures
If one or more of the pre-checks fail, resolve the related issue and start the upgrade again. In the NetQ UI these failures appear on the Upgrade Preview page. In the NetQ CLI, it appears in the form of error messages in the netq lcm show upgrade-jobs cl-image command output.
Analyze Results
After starting the upgrade you can monitor the progress in the NetQ UI. Successful upgrades are indicated by a green . Failed upgrades display error messages indicating the cause of failure.
To view the progress of current upgrade jobs and the history of previous upgrade jobs using the CLI, run netq lcm show upgrade-jobs cl-image.
To see details of a particular upgrade job, run netq lcm show status job-ID.
To see only Cumulus Linux upgrade jobs, run netq lcm show status cl-image job-ID.
Download details about the upgrade in a JSON-formatted file, by clicking Download report.
Post-check Failures
A successful upgrade can still have post-check warnings. For example, you updated the OS, but not all services are fully up and running after the upgrade. If one or more of the post-checks fail, warning messages appear in the Post-Upgrade Tasks section of the preview. Click the warning category to view the detailed messages.
Network Snapshots
Snapshots capture a network’s state—including the services running on the network—at a particular point in time. Comparing snapshots lets you check what (if anything) changed in the network, which can be helpful when upgrading a switch or modifying its configuration. This section outlines how to create, compare, and interpret snapshots.
Create a Network Snapshot
To create a snapshot:
From the workbench header, select Snapshot, then Create snapshot.
Next, enter the snapshot’s name, time frame, and the elements you’d like included in the snapshot:
To capture the network’s current state, click Now. To capture the network’s state at a previous date and time, click Past, then in the Start Time field, select the calendar icon.
The Choose options field includes all the elements and services that may run on the network. All are selected by default. Click any element to remove it from the snapshot. Nodes and services are included in all snapshots.
The Notes field is optional. You can add a note as a reminder of the snapshot’s purpose.
Select Finish. The card now appears on your workbench.
When you are finished viewing the snapshot, click Dismiss to remove it from your workbench. You can add it back by selecting Snapshot in the header and navigating to the option to view snapshots.
Compare Network Snapshots
You can compare the state of your network before and after an upgrade or other configuration change to help avoid unwanted changes to your network’s state.
To compare network snapshots:
From the workbench header, select Snapshot.
Select Compare snapshots, then select the two snapshots you want to compare.
Click Finish.
If the snapshot cards are already on your workbench, place the cards side-by-side for a high-level comparison. For a more detailed comparison, click Compare on one of the cards and select a snapshot for comparison from the list.
Interpreting the Comparison Data
For each network element with changes, a visualization displays the differences between the two snapshots. Green represents additions, red represents subtractions, and orange represents updates.
In the following example, Snapshot 3 and Snapshot 4 are being compared. Snapshot 3 has a BGP count of 212 and Snapshot 4 has a BGP count of 186. The comparison also shows 98 BGP updates.
From this view, you can dismiss the snapshots or select View Details for additional information and to filter and export the data as a JSON file.
The following table describes the information provided for each element type when changes are present:
Element
Data Descriptions
BGP
Hostname: Name of the host running the BGP session
VRF: Virtual route forwarding interface if used
BGP session: Session that was removed or added
ASN: Autonomous system number
Config
Hostname: Name of the host where the configuration file was added or removed
Configuration file: File that was added or removed
Interface
Hostname: Name of the host where the interface resides
Interface name: Name of the interface that was removed or added
IP Address
Hostname: Name of the host where address was removed or added
Prefix: IP address prefix
Mask: IP address mask
Interface name: Name of the interface that owns the address
Links
Hostname: Name of the host where the link was removed or added
Events provide information about how a network and its devices are operating during a given time period. They help with troubleshooting and alert network administrators to potential network problems before they become critical. You can view events in the UI or CLI and receive notifications about events via Slack, PagerDuty, syslog, email, or a generic webhook channel.
NetQ captures three types of events:
System events: a wide range of events generated by the system about network protocols and services operation, hardware and software status, and system services
Threshold-crossing events: a user-specified set of system-related events based on threshold values
What Just Happened events: network hardware events for NVIDIA Spectrum™ switches
You can track events in the NetQ UI with the Events and What Just Happened cards:
Events card: displays system and threshold-crossing events
What Just Happened card: displays network hardware events on NVIDIA Spectrum™ switches
You can monitor system and threshold-crossing events in the CLI with the netq show events command. The netq show wjh-drop command lists all What Just Happened events or those with a selected drop type.
Manage NetQ Agents
Run the following commands to view the status of an agent, disable an agent, manage logging, and configure the events the agent collects.
View NetQ Agent Status
The syntax for the NetQ Agent status command is:
netq [<hostname>] show agents
[fresh | dead | rotten | opta]
[around <text-time>]
[json]
You can view the status for a given switch, host or NetQ appliance or virtual machine. You can also filter by the status and view the status at a time in the past.
To view the current status of all NetQ Agents, run:
cumulus@switch~:$ netq show agents
To view NetQ Agents that are not communicating, run:
cumulus@switch~:$ netq show agents rotten
No matching agents records found
To view NetQ Agent status on the NetQ appliance or VM, run:
cumulus@switch~:$ netq show agents opta
Matching agents records:

View NetQ Agent Configuration
You can view the current configuration of a NetQ Agent to determine what data it collects and where it sends that data. The syntax for this command is:
sudo netq config show agent
[cpu-limit|frr-monitor|loglevel|ssl|stats|wjh|wjh-threshold]
[json]
The following example shows a NetQ Agent in an on-premises deployment, talking to an appliance or VM at 127.0.0.1 using the default ports and VRF.
To view the configuration of a particular aspect of a NetQ Agent, use the various options.
This example shows a NetQ Agent configured with a CPU limit of 60%.
cumulus@switch:~$ sudo netq config show agent cpu-limit
CPU Quota
-----------
60%
()
Modify the Configuration of the NetQ Agent on a Node
The agent configuration commands let you:
Add, disable, and remove a NetQ Agent
Start and stop a NetQ Agent
Configure a NetQ Agent to collect selected data (CPU usage limit, FRR, Kubernetes, WJH)
Configure a NetQ Agent to send data to a server cluster
Troubleshoot the NetQ Agent
Commands apply to one agent at a time, and you run them on the switch or host where the NetQ Agent resides.
Add or Remove a NetQ Agent
To add or remove a NetQ Agent, you must add or remove the IP address (as well as the port and VRF, if specified) from the NetQ configuration file, /etc/netq/netq.yml. This adds or removes the information about the server where the agent sends the data it collects.
To use the NetQ CLI to add or remove a NetQ Agent on a switch or host, run:
If you want to use a specific port on the server, use the port option. If you want the data sent over a particular virtual route interface, use the vrf option.
This example shows how to add a NetQ Agent and tell it to send the data it collects to the NetQ server at the IPv4 address of 10.0.0.23 using the default port (port 31980 for on-premises and port 443 for cloud deployments) and the default VRF (mgmt). The port and VRF are not specified, so NetQ assumes default settings.
This example shows how to add a NetQ Agent and tell it to send the data it collects to the NetQ server at the IPv4 address of 10.0.0.23 using the default port (port 31980 for on-premises and port 443 for cloud deployments) and the default VRF for a switch managed through an in-band connection on interface swp1:
You can temporarily disable the NetQ Agent on a node. Disabling the NetQ Agent maintains the data already collected in the NetQ database, but stops the NetQ Agent from collecting new data until you reenable it.
To disable a NetQ Agent, run:
cumulus@switch:~$ sudo netq config stop agent
To reenable a NetQ Agent, run:
cumulus@switch:~$ sudo netq config restart agent
Configure a NetQ Agent to Limit Switch CPU Usage
You can limit the NetQ Agent to use only a certain percentage of CPU resources on a switch. This setting requires a switch running Cumulus Linux versions 3.7, 4.1, or later.
You must separate the list of IP addresses by commas (not spaces). You can optionally specify a port or VRF.
This example configures the NetQ Agent on a switch to send the data to three servers located at 10.0.0.21, 10.0.0.22, and 10.0.0.23 using the rocket VRF.
To stop a NetQ Agent from sending data to a server cluster, run:
cumulus@switch:~$ sudo netq config del agent cluster-servers
Configure Logging to Troubleshoot a NetQ Agent
The logging level used for a NetQ Agent determines what types of events get 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 debug, info, warning, and error messages.
info
Sends notifications for info, 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:
(Optional) Verify the connection to the NetQ appliance or VM by viewing the netq-agent.log messages.
Disable Agent Logging
If you set the logging level to debug for troubleshooting, NVIDIA recommends that you either change the logging level to a less verbose mode or disable agent logging when you finish troubleshooting.
To change the logging level from debug to another level, run:
The NetQ Agent contains a pre-configured set of modular commands that run periodically and send event and resource data to the NetQ appliance or VM. You can fine tune which events the agent can poll and vary frequency of polling using the NetQ CLI.
For example, if your network is not running OSPF, you can disable the command that polls for OSPF events. Or you can decrease the polling interval for LLDP from the default of 60 seconds to 120 seconds. By not polling for selected data or polling less frequently, you can reduce switch CPU usage by the NetQ Agent.
Depending on the switch platform, the NetQ Agent might not execute some supported protocol commands. For example, if a switch has no VXLAN capability, then the agent skips all VXLAN-related commands.
Supported Commands
To see the list of supported modular commands, run:
You can change the polling frequency (in seconds) of a modular command. For example, to change the polling frequency of the lldp-json command to 60 seconds from its default of 120 seconds, run:
You can disable unnecessary commands. This can help reduce the compute resources the NetQ Agent consumes on the switch. For example, if your network does not run OSPF, you can disable the two OSPF commands:
Use the UI or CLI to monitor your network’s inventory of switches, hosts, NICs, and DPUs. The inventory includes a count for each device and information about the hardware and software components on individual switches, such as the operating system, motherboard, ASIC, microprocessor, disk, memory, fan, and power supply information.
Networkwide Inventory Commands
Several forms of this command are available based on the inventory component you’d like to view. See the command line reference for additional options, definitions, and examples.
netq show inventory (brief | asic | board | cpu | disk | memory | os)
View Networkwide Inventory in the UI
To view the quantity of devices in your network, open the Inventory/Devices card. The medium-sized card displays the total number of devices in the network. Hover your cursor over the chart to view the number and percentage of switches, hosts, NICS, and DPUs that comprise your network.
Expand to the large card to view the distribution of ASIC vendors, OS versions, NetQ Agent versions, and platforms deployed across all switches in your network. You can hover over and select any of the segments in the distribution chart to highlight and filter data, including:
Name or value of the component type, such as the version number or status

View Switch Inventory in the UI
Add the Inventory/Switches card to your workbench to monitor the hardware and software component inventory on switches running NetQ in your network. To add this card to your workbench, select Add card>Inventory>Inventory/Switches card>Open cards. The card displays the total number of switches in your network, divided into the number of fresh and rotten switches.
View Distribution and Component Counts
Open the large Inventory/Switches card to display more granular information about software and hardware distribution. By default, the card displays data for fresh switches. Select Rotten switches from the dropdown to display information for switches that are in a down state. Hover over the top of the card and select a category to restrict the view to ASICs, platform, or software.
Expand the Inventory/Switches card to full-screen to view, filter or export information about ASICs, motherboards, CPUs, memory, disks, and operating system.
Decommission a Switch
Decommissioning a switch or host removes information about the device from the NetQ database. When the NetQ Agent restarts at a later date, it sends a connection request back to the database, so NetQ can monitor the switch or host again.
Locate the Inventory/Switches card on your workbench and expand it to full-screen.
Select the switches to decommission, then select Decommission device above the table.
If you attempt to decommission a switch that is assigned a default, unmodified access profile, the process will fail. Create a unique access profile (or update the default with unique credentials), then attach the profile to the switch you want to decommission.
Confirm the devices you want to decommission.
Wait for the decommission process to complete, then select Done.
To decommission a switch or host:
On the given switch or host, stop and disable the NetQ Agent service:
In the UI, you can view your inventory of hosts across the network or individually, including a host’s operating system, ASIC, CPU model, disk, platform, and memory information.
Access and View Host Inventory Data
The Inventory/Hosts card monitors the hardware- and software-component inventory on hosts running NetQ in your network. To add this card to your workbench, select Add card>Inventory>Inventory/Hosts card>Open cards.
Hover over the chart in the default card view to view component details. To view the distribution of components, hover over the card header and increase the card’s size. Select the corresponding icon to view a detailed chart for ASIC, platform, or software components:
To display detailed information as a table, expand the card to its largest size:
Decommission a Host
Decommissioning hosts removes information about the host from the NetQ database. The NetQ Agent must be disabled and in a ‘rotten’ state to complete the decommissioning process.
Locate the Inventory/Devices card on your workbench and expand it to full-screen.
From the Hosts tab, locate the Agent state column.
If the NetQ Agents is in a ‘fresh’ state, you must stop and disable the NetQ Agent and wait until it reflects a ‘rotten’ state. To disable the agent, run the following commands on the host you want to decommission:
It may take a few minutes for the agent’s new state to be reflected in the UI.
After you have confirmed that the agent is in a ‘rotten’ state, select the host you’d like to decommission, then select Decommission device above the table.
To decommission a host:
Stop and disable the NetQ Agent service on the host:
When you discover operational anomalies, you can check whether the devices, hosts, network protocols, and services are operating as expected. NetQ lets you see when changes have occurred to the network, devices, and interfaces by viewing their operation, configuration, and status at an earlier point in time.

View and Run Validations in the UI
The Validation Summary card displays a summary of validation checks from the past 24 hours. Select Validation in the header to create or schedule new validation checks, as well as view previous checks.
Validation with the NetQ CLI
The NetQ CLI uses the netq check commands to validate the various elements of your network fabric, looking for inconsistencies in configuration across your fabric, connectivity faults, missing configurations, and so forth. You can run commands from any node in the network.
View Default Validation Tests
To view the list of tests run for a given protocol or service by default, use either netq show unit-tests <protocol/service> or perform a tab completion on netq check <protocol/service> [include|exclude]. Refer to Validation Tests Reference for a description of the individual tests.
Select Which Tests to Run
You can include or exclude one or more of the various tests performed during the validation. Each test is assigned a number, which is used to identify the tests. By default, all tests are run. The <protocol-number-range-list> value is used with the include and exclude options to indicate which tests to include. It is a number list separated by commas, or a range using a dash, or a combination of these. Do not use spaces after commas. For example:
include 1,3,5
include 1-5
include 1,3-5
exclude 6,7
exclude 6-7
exclude 3,4-7,9
The output indicates whether a given test passed, failed, or was skipped.
Example Validation Test
The following example shows a BGP validation that includes only the session establishment and router ID tests. Note that you can obtain the same results using either of the include or exclude options and that the test that is not run is marked as skipped.
cumulus@switch:~$ netq show unit-tests bgp
0 : Session Establishment - check if BGP session is in established state
1 : Address Families - check if tx and rx address family advertisement is consistent between peers of a BGP session
2 : Router ID - check for BGP router id conflict in the network
Configured global result filters:
Configured per test result filters:
cumulus@switch:~$ netq check bgp include 0,2

Failed nodes : 0
Rotten nodes : 0
Warning nodes : 0
Additional summary:
Total Sessions : 54
Failed Sessions : 0
Session Establishment Test : passed
Address Families Test : skipped
Router ID Test : passed
Validation Check Result Filtering
You can create filters to suppress false alarms or uninteresting errors and warnings. For example, certain configurations permit a singly connected MLAG bond, which generates a standard error that is not useful.
Filtered errors and warnings related to validation checks do NOT generate notifications and are not counted in events totals. They are counted as part of suppressed notifications instead.
You define these filters in the /etc/netq/check-filter.yml file. 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 comprise multiple criteria, one per line, creating a logical AND. You can match 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 suppresses any events generated by the DataVrf virtual route forwarding interface coming from swp3 or swp7.. 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 provision BGP with configurations where a BGP peer is not expected or desired, then errors that a BGP peer is missing occur. By creating a filter, you can remove the error in favor of a warning.
To create a validation filter:
Navigate to the /etc/netq directory.
Create or open the check_filter.yml file using your text editor of choice.
This file contains the syntax to follow to create one or more rules for one or more protocols or services. Create your own rules, and/or edit and un-comment any example rules you would like to use.
# Netq check result filter rule definition file. This is for filtering
# results based on regex match on one or more columns of each test result.
# Currently, only action 'filter' is supported. Each test can have one or
# more rules, and each rule can match on one or more columns. In addition,
# rules can also be optionally defined under the 'global' section and will
# apply to all tests of a check.
#
# syntax:
#
# <check name>:
# tests:
# <test name, as shown in test list when using the include/exclude and tab>:
# - rule:
# match:
# <column name>: regex
# <more columns and regex.., result is AND>
# action:
# filter
# - <more rules..>
# global:
# - rule:
# . . .
# - rule:

Decommission a DPU
Decommissioning DPUs removes information about the DPU from the NetQ database. The NetQ Agent must be disabled and in a ‘rotten’ state to complete the decommissioning process.
Locate the Inventory/Devices card on your workbench and expand it to full-screen.
From the DPUs tab, locate the Agent state column.
If the NetQ Agent is in a ‘fresh’ state, you must stop and disable the NetQ Agent and wait until it reflects a ‘rotten’ state. To disable the agent, run the following command on the DPU you want to decommission. Replace <netq_server> with the IP address of your NetQ VM:
sed -i s'/<netq_server>/127.0.0.1/g' /etc/kubelet.d/doca_telemetry_standalone.yaml
After you have confirmed that the agent is in a ‘rotten’ state, select the DPU you’d like to decommission, then select Decommission device above the table.
To decommission a host:
Stop and disable the NetQ Agent service on the host. Replace <netq_server> with the IP address of your NetQ VM:
sed -i s'/<netq_server>/127.0.0.1/g' /etc/kubelet.d/doca_telemetry_standalone.yaml
On the NetQ appliance or VM, decommission the DPU:

Device groups allow you to create a label for a subset of devices in the inventory. You can configure validation checks to run on select devices by referencing group names.
Create a Device Group
To create a device group, add the Device Groups card to your workbench. In the header, click Open card. Select the Device groups card:
The Device Groups card will now be displayed on your workbench. Select Create new group and follow the instructions in the UI create a new group:
Enter a name for the group.
Create a hostname-based rule to define which devices in the inventory should be added to the group.
Confirm the expected matched devices appear in the inventory, and click Create device group.
The following example shows a group name of “exit group” matching any device in the inventory with “exit” in the hostname:
Update a Device Group
When new devices that match existing group rules are added to the inventory, NetQ flags the matching devices for review. The following example shows the switch “exit-2” detected in the inventory after the group was configured:
To add the new device to the group inventory, click Add device and then click Update device group.
Delete a Device Group
To delete a device group:
Expand the Device Groups card:
Click Menu on the desired group and select Delete.
Monitor Events
Use the UI or CLI to monitor events: you can view all events across the entire network or all events on a device, then filter events according to their type, severity, or time frame. Event querying is supported for a 72-hour window within the past 30 days.
Note that in the UI, it can take several minutes for NetQ to process and accurately display network events. The delay is caused by events with multiple network dependencies. It takes between 5 and 10 minutes for NetQ to consolidate and display these events.
Monitor events with the following command. See the command line reference for additional options, definitions, and examples.
netq show events
Monitor Events in the UI
Expand the Menu, then select Events.
The dashboard presents a timeline of events alongside the devices that are causing the most events.
Use the controls above the summary to filter events by time, device (hostname), type, severity, or state.
Select the tabs below the controls to display all events networkwide, interface events, network services events, system events, or threshold-crossing events. The charts and tables update according to the tab you’ve selected. In this example, the TCA tab is selected; the chart and tables update to reflect only threshold-crossing events:
Events are also generated when streaming validation checks detect a failure. If an event is generated from a failed validation check, it will be marked resolved automatically the next time the check runs successfully.
Suppress Events
If you are receiving too many event notifications, you can create rules to suppress events. You can also create rules to suppress events attributable to known issues or false alarms. In addition to the rules you create to suppress events, NetQ suppresses some events by default.
You can suppress events for the following types of messages:
agent: NetQ Agent events
bgp: BGP events
btrfsinfo: Events related to the BTRFS file system in Cumulus Linux
clsupport: Events generated when creating the cl-support script
configdiff: Events generated when a configuration file has changed
evpn: EVPN events
lcm: Lifecycle management events
link: Events related to links, including state and interface name
lldp: LLDP events
mlag: MLAG events
ntp: NTP events
ospf: OSPF events
packageinfo:
ptm: Prescriptive Topology Manager events
ptp: PTP events
roceconfig: RoCE configuration events
runningconfigdiff: Events related to the difference between two configurations
sensor: Sensor events
services: Service-related events, including whether a service is active or inactive
ssdutil: Events related to the storage on a switch
NetQ suppresses BGP, EVPN, link, and sensor-related events with a severity level of 'info' by default in the UI. You can disable this rule if you'd prefer to receive these notifications.
Create an Event Suppression Configuration
To suppress events using the NetQ UI:
Click Menu, then Events.
In the top-right corner, select Show suppression rules.
Select Add rule. You can configure individual suppression rules or you can create a group rule that suppresses events for all message types.
Enter the suppression rule parameters and click Create.
When you add a new configuration using the CLI, you can specify a scope, which limits the suppression in the following order:
Hostname.
Severity.
Message type-specific filters. For example, the target VNI for EVPN messages, or the interface name for a link message.
NetQ has a predefined set of filter conditions. To see these conditions, run netq show events-config show-filter-conditions:
cumulus@switch:~$ netq show events-config show-filter-conditions

For example, to create a configuration called mybtrfs that suppresses OSPF-related events on leaf01 for the next 10 minutes, run:
You can delete or disable suppression rules. After you delete a rule, event notifications will resume. Disabling suppression rules pauses those rules, allowing you to receive event notifications temporarily.
To remove suppressed event configurations:
Click Menu, then Events.
Select Show suppression rules at the top of the page.
Toggle between the Single and All tabs to view the suppression rules. Navigate to the rule you want to delete or disable.
Click the three-dot menu and select Delete. To pause the rule instead of deleting it, click Disable.
To remove an event suppression configuration, run netq del events-config events_config_id <text-events-config-id-anchor>.
When you filter for a message type, you must include the show-filter-conditions keyword to show the conditions associated with that message type and the hierarchy in which they get processed.
You can view system events via the NetQ UI or CLI. You can also receive event notifications via a third-party application. This page explains how to integrate NetQ with syslog, PagerDuty, Slack, or email to receive notifications about events on your network. Alternately, you can send notifications to other third-party applications via a generic webhook channel.
In an on-premises deployment, NetQ receives the raw data stream from the NetQ Agents, processes the data, then delivers events to notification channels. In a cloud deployment, NetQ passes the raw data stream to the NetQ Cloud service for processing and delivery.
You can implement a proxy server (that sits between the NetQ appliance or VM and the integration channels) that receives, processes, and distributes the notifications rather than having them sent directly to the integration channel. If you use such a proxy, you must configure NetQ with the proxy information.
NetQ generates notifications for network protocols, interfaces, services, traces, sensors, system software, and system hardware. Refer to the System Events Reference for descriptions and examples of these events.
Event 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. Refer to the Threshold-Crossing Events Reference for descriptions and examples of these events.
Event Message Format
Messages have the following structure:
<message-type><timestamp><opid><hostname><severity><message>
Element
Description
message type
Category of event
timestamp
Date and time event occurred
opid
Identifier of the service or process that generated the event
hostname
Hostname of network device where event occurred
severity
Severity classification: error or info
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 in the following order:
Configure Basic NetQ Event Notifications
The simplest configuration you can create is one that sends all events generated by all interfaces to a single notification application. A notification configuration must contain one channel, one rule, and one filter. Creation of the configuration follows this same path:
Create a channel.
Create a rule that accepts a selected set of events.
Create a filter that associates this rule with the newly created channel.
Create a Channel
The first step is to create a Slack, PagerDuty, syslog, email, or generic channel to receive the notifications.
You can use the NetQ UI or the NetQ CLI to create a Slack channel.
Expand the Menu and select Notification channels.
The Slack tab is displayed by default.
Add a channel.
When no channels have been specified, click Add Slack channel.
When at least one channel has been specified, click Add above the table.
Provide a unique name for the channel. Note that spaces are not allowed. Use dashes or camelCase instead.
Create an incoming webhook as described in the Slack documentation Then copy and paste it in the Webhook URL field.
Click Add.
(Optional) To verify the channel configuration, click Test.
WebHook URL for the desired channel. For example: https://hooks.slack.com/services/text/moretext/evenmoretext
severity <level>
The log level, either info or error. The severity defaults to info if unspecified.
tag <text-slack-tag>
Optional tag appended to the Slack notification to highlight particular channels or people. An @ sign must precede the tag value. For example, @netq-info.
The following example shows the creation of a slk-netq-events channel and verifies the configuration.
Create an incoming webhook as described in the documentation for your version of Slack.
cumulus@switch:~$ netq show notification channel
Matching config_notify records:
Name Type Severity Channel Info
--------------- ---------------- -------- ----------------------
slk-netq-events slack info webhook:https://hooks.s
lack.com/services/text/
moretext/evenmoretext
You can use the NetQ UI or the NetQ CLI to create a PagerDuty channel.
Expand the Menu and select Notification channels.
Click PagerDuty.
Add a channel.
When no channels have been specified, click Add PagerDuty channel.
When at least one channel has been specified, click Add above the table.
Provide a unique name for the channel. Note that spaces are not allowed. Use dashes or camelCase instead.
Obtain and enter an integration key (also called a service key or routing key).
Click Add.
(Optional) To verify the channel configuration, click Test.
cumulus@switch:~$ netq show notification channel
Matching config_notify records:
Name Type Severity Channel Info
--------------- ---------------- ---------------- ------------------------
pd-netq-events pagerduty info integration-key: c6d666e
210a8425298ef7abde0d1998
You can use the NetQ UI or the NetQ CLI to create a syslog channel.
Expand the Menu and select Notification channels.
Click Syslog.
Add a channel.
When no channels have been specified, click Add syslog channel.
When at least one channel has been specified, click Add above the table.
Provide a unique name for the channel. Note that spaces are not allowed. Use dashes or camelCase instead.
Enter the IP address and port of the syslog server.
Click Add.
(Optional) To verify the channel configuration, click Test.
To create and verify a syslog channel, run:
netq add notification channel syslog <text-channel-name> hostname <text-syslog-hostname> port <text-syslog-port> [severity info | severity error ]
netq show notification channel [json]
Option
Description
<text-channel-name>
User-specified syslog channel name
hostname <text-syslog-hostname>
Hostname or IP address of the syslog server to receive notifications
port <text-syslog-port>
Port on the syslog server to receive notifications
severity <level>
The log level, either info or error. The severity defaults to info if unspecified.
The following example shows the creation of a syslog-netq-events channel and verifies the configuration.
Obtain the syslog server hostname (or IP address) and port.
cumulus@switch:~$ netq show notification channel
Matching config_notify records:
Name Type Severity Channel Info
--------------- ---------------- -------- ----------------------
syslog-netq-eve syslog info host:syslog-server
nts port: 514
You can use the NetQ UI or the NetQ CLI to create an email channel.
Expand the Menu and select Notification channels.
Click Email.
Add a channel.
When no channels have been specified, click Add email channel.
When at least one channel has been specified, click Add above the table.
Provide a unique name for the channel. Note that spaces are not allowed. Use dashes or camelCase instead.
Enter a list of emails for the people who you want to receive notifications from this channel.
Enter the emails separated by commas, and no spaces. For example: user1@domain.com,user2@domain.com,user3@domain.com
The first time you configure an email channel, you must also specify the SMTP server information:
Host: hostname or IP address of the SMTP server
Port: port of the SMTP server (typically 587)
User ID/Password: your administrative credentials
From: email address that indicates who sent the notifications
After the first time, any additional email channels you create can use this configuration, by clicking Existing.
Click Add.
(Optional) To verify the channel configuration, click Test.
To create and verify the specification of an email channel, run:
netq add notification channel email <text-channel-name> to <text-email-toids> [smtpserver <text-email-hostname>] [smtpport <text-email-port>] [login <text-email-id>] [password <text-email-password>] [severity info | severity error ]
netq add notification channel email <text-channel-name> to <text-email-toids>
netq show notification channel [json]
The configuration is different depending on whether you are using the on-premises or cloud version of NetQ. Do not configure SMTP for cloud deployments as the NetQ cloud service uses the NetQ SMTP server to push email notifications.
For an on-premises deployment:
Set up an SMTP server. The server can be internal or public.
Create a user account (login and password) on the SMTP server. NetQ sends notifications to this address.
Create the notification channel using this form of the CLI command:
netq del notification rule <text-rule-name-anchor>
▼
Example rules
This example creates a rule named all-interfaces, using the key ifname and the value ALL, which sends all events from all interfaces to any channel with this rule.
cumulus@switch:~$ netq add notification rule all-interfaces key ifname value ALL
Successfully added/updated rule all-ifs
cumulus@switch:~$ netq show notification rule
Matching config_notify records:

Additional filter examples
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 list the filter first, use the
before option.
Filter names can 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.
As you create filters, they are added to the bottom of a list of filters. By default, NetQ processes event messages against filters starting at the top of the filter list and works its way down until it finds a match. NetQ applies the first filter that matches an event message, ignoring the other filters. Then it moves to the next event message and reruns the process, starting at the top of the list of filters. NetQ ignores events that do not match any filter.
You might have 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.
To delete notification filters, run:
netq del notification filter <text-filter-name-anchor>
Delete a Channel
You can remove channels if they are not part of an existing notification configuration.
To remove notification channels:
Expand the Menu and select Notification channels.
Select the tab for the type of channel you want to remove.
Select one or more channels.
Click Delete.
To remove notification channels, run:
netq del notification channel <text-channel-name-anchor>
This example removes a Slack integration and verifies it is no longer in
the configuration:
cumulus@switch:~$ netq del notification channel slk-netq-events
cumulus@switch:~$ netq show notification channel
Matching config_notify records:
Name Type Severity Channel Info
--------------- ---------------- ---------------- ------------------------
pd-netq-events pagerduty info integration-key: 1234567
890
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 you do not specify a port, NetQ defaults to port 80. NetQ supports one proxy server. To simplify deployment, configure your proxy server before configuring channels, rules, or filters.
You can remove the proxy server with netq del notification proxy. This changes the NetQ behavior to send events directly to the notification channels.
Rule Keys and Values Reference
A single key-value pair comprises each rule. 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 can only create rules after you have set up your notification channels.
NetQ includes a predefined fixed set of valid rule keys. You enter values as regular expressions, which vary according to your deployment.

Examples of Advanced Notification Configurations
The following section lists examples of advanced notification configurations.
Create a Notification for BGP Events from a Selected Switch
This example creates a notification integration with a PagerDuty channel called pd-netq-events. It then creates 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 is filtered to the pd-netq-events channel.

Create a Notification for Errors on a Given EVPN VNI
This example creates a notification integration with a PagerDuty channel called pd-netq-events. It then creates a rule evpnVni and a filter called 3vni42 for any error messages from VNI 42 on the EVPN overlay network. The result is that any event messages from VNI 42 with a severity level of ‘error’ are filtered to the pd-netq-events channel.

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 identifying a top of rack switch’s effects on containers.
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, services, and so forth. NetQ works with any container network interface (CNI), including Calico and 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 the impact on a pod, services, replica set or deployment 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 the distribution of Kubernetes workloads within a network.
Requirements
The NetQ Agent supports Kubernetes version 1.9.2 or later.
Command Summary
A large set of commands are 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 view the commands. Refer to the command line reference for additional details.
Enable Kubernetes Monitoring
For Kubernetes monitoring, the NetQ Agent must be installed, running, and enabled on the hosts providing the Kubernetes service.
To enable NetQ Agent monitoring of the containers using the Kubernetes API, you must configure the following on the Kubernetes master node:
Install and configure the NetQ Agent and CLI on the master node.
After waiting for a minute, run the show command to view the cluster:
cumulus@host:~$netq show kubernetes cluster
Next, you must enable the NetQ Agent on every worker node for complete insight into your container network. Repeat steps 2 and 3 on each worker node.
View Status of Kubernetes Clusters
Run the netq show kubernetes cluster command to view the status of all Kubernetes clusters in the fabric. The following example shows two clusters: one with server11 as the master server and the other with server12 as the master server. Both are healthy and both list their associated worker nodes.
cumulus@host:~$ netq show kubernetes cluster
Matching kube_cluster records:

server12:3.0.0.69 default Healthy Healthy server12 server21 se
rver23 server13 serv
er14 server21 server

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:

View Changes to a Cluster
If data collection from the NetQ Agents is not occurring as it did previously, verify that no changes made to the Kubernetes cluster configuration use the around option. Be sure to include the unit of measure with the around value. Valid units include:
w: weeks
d: days
h: hours
m: minutes
s: seconds

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 the nodes in the cluster with server11 as the master. Note that server11 acts as a worker node along with the other nodes in the cluster, server12, server13, server22, server23, and server24.
To display the kubelet or Docker version, use the components option with the show command. This example lists the kublet version, a proxy address if used, and the status of the container for server11 master and worker nodes.
To view only the details for a selected node, the name option with the hostname of that node following the components option:

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. The following example looks 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 you deployed the pod, and shows the peer for each server interface. This data appears 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 communication paths, through interfaces swp1-4 out varying ports to peer interfaces swp7 and swp20 on torc-21, torc-22, edge01 and edge02 nodes. Similarly, it shows the connections 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 shows the services available in the Kubernetes cluster:
You can filter the list to view details about a particular Kubernetes service using the name option, as shown here:
cumulus@host:~$ netq show kubernetes service name calico-etcd

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

View Kubernetes Cluster Configuration in the Past
You can use the around option to go back in time to check the network status and identify any changes that occurred on the network.
This example shows the current state of the network. Notice there is a node named server23. server23 is there because the node server22 went down and Kubernetes spun up a third replica on a different host to satisfy the deployment requirement.
View the Impact of Connectivity Loss for a Deployment
You can determine the impact on the Kubernetes deployment in the event a host or switch goes down. The output is color coded (not shown in the example below) so you can clearly see the impact: green shows no impact, yellow shows partial impact, and red shows full impact.
If you need to perform maintenance on the Kubernetes cluster itself, use the following commands to bring the cluster down and then back up.
Display the list of all the nodes in the Kubernetes cluster:
cumulus@host:~$ kubectl get nodes
Tell Kubernetes to drain the node so that the pods running on it are gracefully scheduled elsewhere:
cumulus@host:~$ kubectl drain <node name>
After the maintenance window is over, put the node back into the cluster so that Kubernetes can start scheduling pods on it again:
cumulus@host:~$ kubectl uncordon <node name>
Configure and Monitor Threshold-Crossing Events
Threshold-crossing events are user-defined events that detect and prevent network failures for ACL resources, BGP, digital optics, ECMP, forwarding resources, interface errors and statistics, link flaps, resource utilization, RoCE, sensors, and What Just Happened events.
Click Menu and navigate to Threshold crossing rules.
Select the tab that reflects the event type for the rule.
Click Create a rule. Enter a name for the rule and assign a severity, then click Next.
Select the attribute you want to monitor. The listed attributes change depending on the type of event you chose in the previous step.
Click Next.
On the Set threshold step, enter a threshold value.
For digital optics, you can choose to use the thresholds defined by the optics vendor (default) or specify your own.
Define the scope of the rule.
If you want to restrict the rule based on a particular parameter, enter values for one or more of the available attributes. For What Just Happened rules, select a reason from the available list.
If you want the rule to apply to across the network, select the Apply rule to entire network toggle.
Click Next.
(Optional) Select a notification channel where you want the events to be sent.
Only previously created channels are available for selection. If no channel is available or selected, the notifications can only be retrieved from the database. You can add a channel at a later time and then add it to the rule.
Click Finish. The rules may take several minutes to appear in the UI.
The simplest configuration you can create is one that sends a TCA event generated by all devices and all interfaces to a single notification application. Use the netq add tca command to configure the event. Its syntax is:
Note that the event ID is case-sensitive and must be in all uppercase.
For example, this rule tells NetQ to deliver an event notification to the tca_slack_ifstats pre-configured Slack channel when the CPU utilization exceeds 95% of its capacity on any monitored switch:
This rule tells NetQ to deliver an event notification to the tca_pd_ifstats PagerDuty channel when the number of transmit bytes per second (Bps) on the leaf12 switch exceeds 20,000 Bps on any interface:
This rule tells NetQ to deliver an event notification to the syslog-netq syslog channel when the temperature on sensor temp1 on the leaf12 switch exceeds 32 degrees Celcius:
This rule tells NetQ to deliver an event notification to the tca-slack channel when the total number of ACL drops on the leaf04 switch exceeds 20,000 for any reason, ingress port, or drop type.
For a Slack channel, the event messages should be similar to this:
Set the Severity of a Threshold-crossing Event
In addition to defining a scope for TCA rule, you can also set a severity of either info or error. To add a severity to a rule, use the severity option.
For example, if you want to add an error severity to the CPU utilization rule you created earlier:
Digital optics have the additional option of applying user- or vendor-defined thresholds, using the threshold_type and threshold options.
This example shows how to send an error to channel ch1 when the upper threshold for module voltage exceeds the vendor-defined thresholds for interface swp31 on the mlx-2700-04 switch.
This example shows how to send an error to channel ch1 when the upper threshold for module voltage exceeds the user-defined threshold of 3V for interface swp31 on the mlx-2700-04 switch.
Now you have four rules created (the original one, plus these three new ones) all based on the TCA_SENSOR_TEMPERATURE_UPPER event. To identify the various rules, NetQ automatically generates a TCA name for each rule. As you create each rule, NetQ adds an _# 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.
View Threshold-crossing Rules
Click Menu and navigate to Threshold crossing rules.
Select the relevant tab. The UI displays each rule and its parameters as a card. Each attribute is displayed on the rule card as a regular expression:
Equals is displayed as an equals sign (=)
Starts with is displayed as a caret (^)
Blank (all) is displayed as an asterisk (*)
This example indicates that the rule applies across all interfaces on the exit-1 switch.
After creating a rule, you can use the filters that appear above the rule cards to filter by status, severity, channel, and/or events.

Manage Threshold-crossing Event Notifications
Change the Threshold on a Rule
After receiving notifications based on a rule, you might want to increase or decrease the threshold value to limit or increase the number of events you receive.
To modify the threshold:
Locate the rule you want to modify and hover over the top of the card.
Click Edit.
Enter a new threshold value, then select Update rule.
After receiving notifications based on a rule, you might find that you want to narrow or widen the scope value to limit or increase the number of events you receive.
To modify the scope:
Locate the rule you want to modify and hover over the top of the card.
Click Edit.
Select the toggle to either apply the rule to the entire network or individual hosts.
This example changes the scope for the rule TCA_CPU_UTILIZATION_UPPER to apply only to switches beginning with a hostname of leaf. You must also provide a threshold value. This example case uses a value of 95 percent. Note that this overwrites the existing scope and threshold values.

Change, Add, or Remove Channels
Locate the rule you want to modify and hover over the top of the card.
You cannot change the name of a threshold-crossing rule using the NetQ CLI because the rules do not have names. They receive identifiers (the tca_id) automatically. In the NetQ UI, to change a rule name, you must delete the rule and re-create it with the new name.
Change the Severity of a Rule
Threshold-crossing rules are categorized as either info or error.
In the NetQ UI, you must delete the rule and re-create it, specifying the new severity.
In the NetQ CLI, to change the severity, run:
netq add tca tca_id <text-tca-id-anchor> (severity info | severity error)
This example changes the severity of the maximum CPU utilization 1 rule from error to info:
During troubleshooting or switch maintenance, you might want to suppress a rule to prevent erroneous or excessive notifications. This effectively pauses notifications for a specified time period.
Locate the rule you want to disable and click Disable.
Select the Date/Time field to set when you want the rule to be reenabled.
Click Disable.
Note the changes in the card:
The state changes to Snoozed
The Suppressed field displays the date and time at which the rule will be reenabled.
The Disable button changes to Disable forever.
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.
To reenable the rule, set the is_active option to true.
Delete a Rule
To delete a rule:
Locate the rule you want to remove and hover over the card.
In the card’s top-right corner, select Delete.
To remove a rule altogether, run:
netq del tca tca_id <text-tca-id-anchor>
This example deletes the maximum receive bytes rule:
cumulus@switch:~$ netq del tca tca_id TCA_RXBYTES_UPPER_1
Successfully deleted TCA TCA_RXBYTES_UPPER_1
Resolve Scope Conflicts
There might be occasions where the scopes defined by multiple threshold-crossing rules overlap. In such cases, NetQ uses the rule with the most specific scope that is still true to generate the event.
To clarify this, consider this example. Three events 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 threshold-crossing event against hostname and interface name with three threshold-crossing 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:

BGP
Use the UI or CLI to monitor Border Gateway Protocol (BGP) on a networkwide or per-session basis.
BGP Commands
Monitor BGP with the following commands. See the command line reference for additional options, definitions, and examples.
netq show bgp
netq show events message_type bgp
netq show events-config message_type bgp
The netq check bgp command checks for consistency across BGP sessions in your network fabric.
netq check bgp
View BGP in the UI
To add the BGP card to your workbench, navigate to the header and select Add card > Network services > All BGP Sessions card > Open cards. In this example, there are 44 nodes running the BGP protocol, 252 open events (from the last 24 hours), and 9 nodes with unestablished sessions.
Expand to the large card for additional BGP info. By default, the card displays the Sessions summary tab. From here you can see which devices are handling the most BGP sessions, or select the dropdown to view nodes with the most unestablished BGP sessions. You can view BGP-related events by selecting the Events tab.
Expand the BGP card to full-screen to view, filter, or export:
Virtual routing and forwarding (VRF) information
Autonomous system number (ASN) assignments
Peer ASNs
The received address prefix for IPv4/IPv6/EVPN when the session is established
From this table, you can select a row, then click Open card above the table.
NetQ adds a new, BGP ‘single-session’ card to your workbench. From this card, you can view session state changes and compare them with events, and monitor the running BGP configuration and changes to the configuration file.
Before adding a BGP single-session card, verify that both the peer hostname and peer ASN are valid. This ensures the information presented is reliable.
Monitor a Single BGP Session
The BGP single-session card displays the node, its peer, its status (established or unestablished), and its router ID. This information can help you determine the stability of the BGP session between two devices. The heat map indicates the status of the session over the designated time period. In this example, the session has been established throughout the entire time period:
Understanding the Heat Map
On the medium and large single-session cards, vertically stacked heat maps represent the status of the sessions: 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 indicate that the status varies. A vertical stack of time blocks, one from each map, includes the results from all checks during that time. The results appear by how saturated the color is for each block. If only established sessions occurred during that time period for the entire time block, then the top block is 100% saturated (white) and the unestablished block is 0% saturated (gray). As unestablished sessions increase in saturation, the established sessions block is proportionally reduced in saturation. The following table lists the most common time periods, their corresponding number of blocks, and the amount of time represented by one block:

View Changes to the BGP Service Configuration File
Each time a change is made to the configuration file for the BGP service, NetQ logs the change and lets you compare it with the previous version. This can be useful when you are troubleshooting potential causes for events or sessions losing their connections.
To view the configuration file changes:
From the large single-session card, select the Configuration File Evolution tab.
Select the time.
Choose between the File view and the Diff view.
The File view displays the content of the file:
The Diff view highlights the changes (if any) between this version (on left) and the most recent version (on right) side by side:
The Validation Summary card in the NetQ UI lets you view the overall health of your network at a glance, giving you a high-level understanding of how well your network is operating. Successful validation results determine overall network health shown in this card.
View Key Metrics of Network Health
Overall network health in the NetQ UI is a calculated average of several key health metrics: system, network services, and interface health.
System health represents the NetQ Agent and sensor health validations. In all cases, validation checks are performed on the agents. If you are monitoring platform sensors, the validation checks include these as well.
Network service health represents the individual network protocol and services validation checks. In all cases, checks are performed on NTP. If you are running BGP, EVPN, MLAG, OSPF, or VXLAN protocols the validation checks include these as well.
Interface health represents the interfaces, VLAN, and link MTU validation checks.
To view network health metrics:
Open or locate the Validation Summary card on your workbench.
Each metric displays a distribution of the validation results for each category. Hover over the individual categories to view detailed metrics for specific validation checks.
In this example, system health is good, but network services and interface health display validation failures:
View Detailed Network Health
To view details about your network’s health, open or locate the large Validation Summary card on your workbench. To view devices with the most issues or recent issues, select the Most failures tab or Recent failures tab, respectively. You can unselect one or more services on the left side of the card to display devices affected by the selected services on the right side of the card.
By default, the System health tab is displayed.
The health of agents and sensors is represented on the left side of the card. Hover over the chart for each type of validation to see detailed results. The right side of the card displays devices with failures related to agents and sensors.
Click the Network service health tab.
The health of each network protocol or service is represented on the left side of the card. Hover over the chart for each type of validation to see detailed results. The right side of the card displays devices with failures related to these protocols and services.
Click the Interface health tab.
The health of interfaces, VLANs, and link MTUs is represented on the left side of the card. Hover over the chart for each type of validation to see detailed results. The right side of the card displays devices with failures related to interfaces, VLANs, and link MTUs.
View Details of a Particular Service
From the relevant tab (System Health, Network Service Health, or Interface Health) on the large Validation Summary card, you can select a chart to open a full-screen view of the validation data for that service.
The following example shows the EVPN chart:
View Default Network Protocol and Service Validation Results
Expand the Validation Summary card to full-screen to view all default validation checks during a designated time period. Some validations, such as RoCE and address, are not included in the default validation checks and will not appear in this view. You can run an on-demand validation to view results for those protocols and services.
Configure and Monitor What Just Happened
What Just Happened (WJH) 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.
Using WJH in combination with NetQ helps you identify 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 pinpoint where communication is failing in the network
WJH is only supported on NVIDIA Spectrum switches running Cumulus Linux 4.4.0 or later. WJH latency and congestion monitoring is supported on NVIDIA Spectrum-2 switches and later. SONiC only supports collection of WJH data with gNMI.
By default, Cumulus Linux 4.4.0 and later includes the NetQ Agent and CLI. Depending on the version of Cumulus Linux running on your NVIDIA switch, you might need to upgrade the NetQ Agent and CLI to the latest release:
WJH is enabled by default on NVIDIA Spectrum switches running Cumulus Linux 4.4.0 or later. Before WJH can collect data, you must enable the NetQ Agent on your switches and servers.
To enable WJH on any switch or server:
Configure the NetQ Agent on the switch:
cumulus@switch:~$ sudo netq config add agent wjh
Restart the NetQ Agent to begin collecting WJH data:
cumulus@switch:~$ sudo netq config restart agent
When you finish viewing WJH metrics, you can stop the NetQ Agent from collecting WJH data to reduce network traffic. Use netq config del agent wjh followed by netq config restart agent to disable WJH on a given switch.
Using wjh_dump.py on an NVIDIA platform that is running Cumulus Linux and the NetQ Agent causes the NetQ WJH client to stop receiving packet drop call backs. To prevent this issue, run wjh_dump.py on a system other than the one where the NetQ Agent has WJH enabled, or disable wjh_dump.py and restart the NetQ Agent with netq config restart agent.
View What Just Happened Metrics
You can view the WJH metrics from the NetQ UI or the NetQ CLI. WJH metrics are visible on the WJH card and the Events card. To view the metrics on the Events card, open the large card and select the WJH tab at the top of the card. For a more detailed view, open the WJH card.
To add the WJH card to your workbench, navigate to the header and select Add card>Events>What Just Happened>Open cards
You can expand the card to see a detailed summary of WJH data, including devices with the most drops, the number of drops, their distribution, and a timeline:
Expand the card to its largest size to open the WJH dashboard. You can also access this dashboard by clicking Menu, then What Just Happened.
The table beneath the charts displays WJH events and recommendations for resolving them. Hover over the color-coded chart to view WJH event categories:
Click on a category in the chart for a detailed view:
Select Advanced view in the top-right corner for a tabular display of drops that can be sorted by drop type. This display includes additional information, such as source and destination IP addresses, ports, and MACs.
For L1 events, you can group entries by switch and ingress port to reduce the number of events displayed. To do this, select the Aggregate by port toggle in the top-right corner.
To view WJH drops, run one of the following commands. Refer to the command line reference for a comprehensive list of options and definitions.
An additional command is available that aggregates WJH L1 errors that occur on the same ingress port.
netq [<hostname>] show wjh-drop l1
[ingress-port <text-ingress-port>]
[severity <text-severity>]
[reason <text-reason>]
[port-aggregate <text-port-aggregate>]
[between <text-time> and <text-endtime>]
[around <text-time>] [json]
This example uses the first form of the command to show drops on switch leaf03 for the past week.
cumulus@switch:~$ netq leaf03 show wjh-drop between now and 7d

Configure Latency and Congestion Thresholds
WJH latency and congestion metrics depend on threshold settings to trigger the events. WJH measures packet latency as the time spent inside a single system (switch). When specified, WJH triggers events when measured values cross high thresholds and events are suppressed when values are below low thresholds.
You can specify multiple traffic classes and multiple ports by separating the classes or ports by a comma (no spaces).
For example, the following command creates latency thresholds for Class 3 traffic on port swp1 where the upper threshold is 10 usecs and the lower threshold is 1 usec:
This example creates congestion thresholds for Class 4 traffic on port swp1 where the upper threshold is 200 cells and the lower threshold is 10 cells, where a cell is a unit of 144 bytes:
Refer to the command line reference for a comprehensive list of options and definitions for this command.
Suppress Events with Filters
You can create filters with the UI or CLI to prevent WJH from generating events. Filters can be applied to a drop category (such as layer 1 drops or buffer drops), a drop reason (for example, “decapsulation error” or “multicast MAC mismatch”), or according to severity level (notice, warning, or error). With the CLI, you can create filters to suppress events according to their source or destination IP addresses.
For a complete list of drop types, reasons, and severity levels, refer to the WJH Events Reference.
Before configuring the NetQ Agent to filter WJH drops, you must generate AuthKeys. Copy the access key and secret key to an accessible location. You will enter them in one of the final steps.
Expand the Menu and select Manage switches.
Select the NetQ agent configurations tab.
On the NetQ Agent Configurations card, select Add config.
Enter a name for the profile. In the WJH row, select Enable, then Customize. By default, WJH includes all drop reasons and severities. Uncheck any drop reasons or severity you do not want to generate WJH events, then click Done.
Select Add to save the configuration profile, or click Close to discard it.
To configure the NetQ Agent to filter WJH drops, run netq config add agent wjh-drop-filter. Use tab completion to view the available drop type, drop reason, and severity values.
With the NetQ UI, you can monitor hardware resources of individual data processing units (DPUs), including CPU utilization, disk usage, and memory utilization. For DPU inventory information, refer to DPU Inventory.
For an overview of the current or past health of DPU hardware resources, open the DPU device card. To open a DPU device card:
Click Devices in the header, then click Open a device card.
Select a DPU from the dropdown.
Click Add. This example shows that the r-netq-bf2-01 DPU has low utilization across CPU, memory, and disks:
View DPU Attributes
For a quick look at the key attributes of a particular DPU, expand the DPU card.
Attributes are displayed as the default tab on the large DPU card. You can view the static information about the DPU, including its hostname, ASIC vendor and model, CPU information, OS version, and agent version.
To view a larger display of hardware resource utilization, select Utilization.
Expand the card to its largest size to view a list of installed packages and RoCE counters for a given DPU. You can filter RoCE information by physical port, priority port, RoCE extended, RoCE, and peripheral component interconnect (PCI).
You can use gRPC Network Management Interface (gNMI) to collect system resource, interface, and counter information from Cumulus Linux and export it to your own gNMI client.
Configure the gNMI Agent
The gNMI agent is disabled by default. To enable it, run:
The gNMI agent listens over port 9339. You can change the default port in case you use that port in another application. The /etc/netq/netq.yml file stores the configuration.
Use the following commands to adjust the settings:
Restart the NetQ agent to incorporate the configuration changes:
cumulus@switch:~$ netq config restart agent
Use the gNMI Agent Only
NVIDIA recommends collecting data with both the gNMI and NetQ agents. However, if you do not want to collect data with both agents, you can disable the NetQ agent. Data is then sent exclusively to the gNMI agent.
To disable the NetQ agent, use the following command:
You cannot disable both the NetQ and gNMI agents. If both agents are enabled on Cumulus Linux and a NetQ server is unreachable, the data from the following models are not sent to gNMI:
openconfig-interfaces
openconfig-if-ethernet
openconfig-if-ethernet-ext
openconfig-system
nvidia-if-ethernet-ext
WJH, openconfig-platform, and openconfig-lldp data continue streaming to gNMI in this state. If you are only using gNMI and a NetQ telemetry server does not exist, you should disable the NetQ agent by setting opta-enable to false.
Supported Models
Cumulus Linux supports the following OpenConfig models:
The client should use the following YANG models as a reference:

Collect WJH Data Using gNMI
You can export What Just Happened data from the NetQ agent to your own gNMI client. Refer to the previous section for the nvidia-if-wjh-drop-aggregate reference YANG model.
Supported Features
The gNMI agent supports capability and stream subscribe requests for WJH events.
If you are using SONiC, WJH data can only be collected using gNMI.
WJH Drop Reasons
The data NetQ sends to the gNMI agent is in the form of WJH drop reasons. The reasons are generated by the SDK and are stored in the /usr/etc/wjh_lib_conf.xml file on the switch. Use this file as a guide to filter for specific reason types (L1, ACL, and so forth), reason IDs, or event severities.

ECMP
Equal-cost multi-path (ECMP) is a routing strategy whereby packets are forwarded along multiple paths of equal cost. Load sharing occurs automatically for IPv4 and IPv6 routes with multiple installed next hops. The hardware or the routing protocol configuration determines the maximum number of routes for which load sharing occurs.
ECMP monitoring is supported on NVIDIA Spectrum switches running Cumulus Linux.
ECMP Commands
Monitor ECMP routing data with the following commands. See the command line reference for additional options, definitions, and examples.
netq show ecmp
netq show ecmp-hash-config
View ECMP Resource Utilization in the UI
You can view resource utilization for ECMP next hops in the full-screen switch card. In the workbench header, select Devices, then click Open a device card. Select a switch from the list. When the card opens on the dashboard, expand it to the largest size.
Select Forwarding resources from the side menu. The ECMP next hops column displays the maximum number of hops seen in the forwarding table, the number used, and the percentage of this usage compared to the maximum number.
Adaptive Routing
Adaptive routing is a load balancing feature that improves network utilization for eligible IP packets by selecting forwarding paths dynamically based on the state of the switch, such as queue occupancy and port utilization. You can use the adaptive routing dashboard to view switches with adaptive routing capabilities, events related to adaptive routing, RoCE settings, and egress queue lengths in the form of histograms.
Adaptive routing monitoring is supported on Spectrum-4 switches. It requires a switch fabric running Cumulus Linux 5.5.0 and later.
Requirements
To display adaptive routing data, you must have adaptive routing configured on the switch; it can be either enabled or disabled. Switches without an adaptive routing configuration will not appear in the UI or CLI. Additionally, RoCE lossless mode must be enabled to display adaptive routing data. Switches with RoCE lossy mode enabled will appear in the UI and CLI, but will not display adaptive routing data.
Adaptive Routing Commands
Monitor adaptive routing with the netq show adaptive-routing config commands. The output of these commands display adaptive routing information either globally on the switch or at the interface level.
netq show adaptive-routing config global
netq show adaptive-routing config interface
Access the Adaptive Routing Dashboard
Select Menu.
Under the Network section, select Adaptive routing.
The adaptive routing dashboard displays:
Devices with adaptive routing configured (enabled or disabled) and their RoCE modes (lossy or lossless).
A list of interfaces on the switch and their configurations. In the Interfaces column, select View details to view interfaces with adaptive routing configured:
A summary of adaptive routing events, including ECMP traffic imbalances.
A list of up to 10 switches, which can be sorted by highest P95 value, highest standard deviation, or ports with the widest deviation from the P95 value (aggregated over the past 3 minutes). From this panel, you can select View more in the View histogram column to display queue lengths in the form of histograms for any listed switch.
EVPN
Use the UI or CLI to monitor Ethernet VPN (EVPN) on a networkwide or per-session basis.
EVPN Commands
Monitor EVPN with the following commands. See the command line reference for additional options, definitions, and examples.
netq show evpn
netq show events message_type evpn
netq show events-config message_type evpn
The netq check evpn command verifies the communication status for all nodes (leafs, spines, and hosts) running instances of EVPN in your network fabric:
netq check evpn
View EVPN in the UI
To add the EVPN card to your workbench, navigate to the header and select Add card > Network services > All EVPN Sessions card > Open cards. In this example, there are 33 nodes running the EVPN service, 0 events (from the last 24 hours), and 23,070 VNIs.
View the Distribution of Layer-2 and -3 VNIs and Sessions
To view the number of sessions between devices and Virtual Network Identifiers (VNIs) that occur over layer 3, open the large EVPN Sessions card. In this example, there are 18 layer-3 VNIs.
Select the dropdown to display the switches with the most EVPN sessions, as well as the switches with the most layer-2 and layer-3 EVPN sessions.
You can view EVPN-related events by selecting the Events tab.

From this table, you can select a row, then click Add card above the table.
NetQ adds a new, EVPN ‘single-session’ card to your workbench. From this card, you can view the number of VTEPs (VXLAN Tunnel Endpoints) for a given EVPN session as well as the attributes of all EVPN sessions for a given VNI.
Monitor a Single EVPN Session
The EVPN single-session card displays the number of VTEPs for a given EVPN session (in this case, 48).
Expand the card to display the associated VRF (layer 3) or VLAN (layer 2) on each device participating in this session. The full-screen card displays all stored attributes of all EVPN sessions running networkwide.
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 for a given host, run netq show lldp and specify the hostname:
Use the CLI to monitor OSI Layer 1 physical components on network devices, including interfaces, ports, links, and peers. You can monitor transceivers and cabling deployed per port (interface), per vendor, per part number, and so forth.
This information can help you:
Determine which ports are empty versus which ones have cables plugged in to help validate expected connectivity.
Audit transceiver and cable components by vendor, helping you estimate replacement costs, repair costs, and overall maintenance costs.
Identify mismatched links.
Identify when physical layer changes (for example, bonds and links going down or flapping) occurred.
NetQ uses
LLDP (Link Layer Discovery Protocol) to collect port information. NetQ can also identify peer ports connected to DACs (Direct Attached Cables) and AOCs (Active Optical Cables) without using LLDP, even if the link is not UP.
View performance and status information about cables, transceiver modules, and interfaces with netq show interfaces physical:

Interface Statistics and Utilization
NetQ Agents collect performance statistics every 30 seconds for the physical interfaces on switches in your network. The NetQ Agent does not collect statistics for non-physical interfaces, such as bonds, bridges, and VXLANs. The NetQ Agent collects the following statistics:
For NetQ Appliances that have 3ME3 solid state drives (SSDs) installed (primarily in on-premises deployments), you can view the utilization of the drive on demand. A warning is generated when a drive drops below 10% health, or has more than a 2% loss of health in 24 hours, indicating the need to rebalance the drive. Tracking SSD utilization over time lets you see any downward trend or drive instability before you receive a warning message.
Customers running Cumulus Linux 3 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, NVIDIA 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 to rebalance.
netq show interfaces
netq show interfaces type
netq show events message_type interfaces
The netq check interfaces command verifies interface communication status for all nodes (leafs, spines, and hosts) or an interface between specific nodes in your network fabric. This command only checks the physical interfaces; it does not check bridges, bonds, or other software constructs.
netq check interfaces
View Link Interfaces in the UI
You can monitor the same information outlined in the section above via the UI by expanding the Menu, then selecting Interfaces.
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. Use the netq check mtu command to verify that the MTU is correctly specified for each link.
IP Addresses
Use the UI or CLI to monitor Internet Protocol (IP) addresses, neighbors, and routes.
This information can help you:
Determine the IP neighbors for each switch.

Validate Network Protocol and Service Operations
NetQ lets you validate the operation of the protocols and services running in your network either on demand or according to a schedule. For a general understanding of how well your network is operating, refer to the Validate Overall Network Health.
On-demand Validations
When you want to validate the operation of one or more network protocols and services right now, you can create and run on-demand validations using the NetQ UI or the NetQ CLI.
Create an On-demand Validation
Using the NetQ UI, you can create an on-demand validation for multiple protocols or services at the same time. This is handy when the protocols are strongly related regarding a possible issue or if you only want to create one validation request.
To run on-demand validations with the CLI, use the netq check commands.
To create and run a request containing checks on one or more protocols or services within the NetQ UI:
In the workbench header, select Validation, then Create a validation. Choose whether the on-demand validation should run on all devices or on specific device groups.
Select the protocols or services you want to validate, then click Next.
This example has BGP selected and displays the 8 checks that NetQ runs during a BGP validation:
Select Now and specify a workbench:
Click Run to start the validation. It might take a few minutes for results to appear.
The respective On-demand Validation Result card opens on your workbench. If you selected more than one protocol or service, a card opens for each selection. To view additional information about the errors reported, hover over a check and click View details. To view all data for all on-demand validation results for a given protocol, click Show all results.
To create a request containing checks on a single protocol or service in the NetQ CLI, run:
netq add validation type (ntp | interfaces | sensors | evpn | vxlan | agents | mlag | vlan | bgp | mtu | ospf | roce | addr) [alert-on-failure]
The associated Validation Result card is accessible from the full-screen Validate Network card.
Run an Existing Scheduled Validation On Demand
To run a scheduled validation now:
Click Validation, then click Existing validations.
Select one or more validations, then click View results.
The associated Validation Result cards open on your workbench.
Scheduled Validations
By default, a scheduled validation for each protocol and service runs every hour. You can disable these validation checks in the UI, but you cannot edit them.
You can create and schedule up to 15 custom validation checks. The hourly, default validation checks do not count towards this limit.
Schedule a Validation
Click Validation, then click Create a validation. Choose whether the scheduled validation should run on all devices or on specific device groups.
Select the protocols or services you want to validate, then click Next.
Click Later then choose when to start the check and how frequently to repeat the check (every 30 minutes, 1 hour, 3 hours, 6 hours, 12 hours, or 1 day).
Click Schedule.
To see the card with the other network validations, click View. If you selected more than one protocol or service, a card opens for each selection. To view the card on your workbench, click Open card.
To create a scheduled request containing checks on a single protocol or service in the NetQ CLI, run:
netq add validation name <text-new-validation-name> type (addr | agents | bgp | evpn | interfaces | mlag | mtu | ntp | ospf | roce | sensors | vlan | vxlan) interval <text-time-min> [alert-on-failure]
The following example creates a BGP validation that runs every 15 minutes:
cumulus@switch:~$ netq add validation name Bgp15m type bgp interval 15m
Successfully added Bgp15m running every 15m
The associated Validation Result card is accessible from the full-screen Scheduled Validation Result card.
View Scheduled Validation Results
After creating scheduled validations with either the NetQ UI or the NetQ CLI, the results appear in the Scheduled Validation Result card. When a request has completed processing, you can access the Validation Result card from the full-screen Validations card. Each protocol and service has its own validation result card, but the content is similar on each.
Granularity of Data Shown Based on Time Period
On the medium and large Validation Result cards, vertically stacked heat maps represent the status of the runs; 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 indicate that the status varies. A vertical stack of time blocks, one from each map, includes the results from all checks during that time. The results appear 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. The example heat map for a time period of 24 hours shown here uses the most common time periods from the table showing the resulting time blocks and regions.

Access and Analyze the Scheduled Validation Results
After a scheduled validation request has completed, the results are available in the corresponding Validation Result card.
To access the results:
In the workbench header, select Validation, then click Existing validations.
Select the validation results you want to view, then click View results.
The medium Scheduled Validation Result card(s) for the selected items appear on your workbench.
To analyze the results:
Note the distribution of results. Are there many failures? Are they concentrated together in time? Has the protocol or service recovered after the failures?
Hover over the heat maps to view the status numbers and what percentage of the total results that represents for a given region. The tooltip also shows the number of devices included in the validation and the number with warnings and/or failures. This is useful when you see the failures occurring on a small set of devices, as it might point to an issue with the devices rather than the network service.
Expand the card to display a chart alongside events metrics. Click to expand or collapse the chart.
You can view the configuration of the request that produced the results shown on this card, by hovering over the card and selecting the Configuration tab.
To view all data available for all scheduled validation results for the given protocol or service, expand the card to full-screen.
In the Checks box, hover over an individual check and select View details for additional information:
Manage Scheduled Validations
You can edit or delete any scheduled validation that you created. Default validations cannot be edited or deleted, but can be disabled.
Edit a Scheduled Validation
At some point you might want to change the schedule or validation types that are specified in a scheduled validation request. This creates a new validation request and the original validation has the (old) label applied to the name. The old validation can no longer be edited.
When you update a scheduled request, the results for all future runs of the validation will be different from the results of previous runs of the validation.
To edit a scheduled validation:
Click Validation, then click Scheduled validations.
Hover over the validation then click Edit.
Select which checks to add or remove from the validation request, then click Update.
Change the schedule for the validation, then click Update.
You can run the modified validation immediately or wait for it to run according to the schedule you specified.

LLDP
Network devices use Layer Link Discovery Protocol (LLDP) to advertise their identity, capabilities, and neighbors on a LAN. You can view this information for one or more devices. You can also view the information at an earlier point in time or view changes that have occurred to the information during a specified time period. For an overview and how to configure LLDP in your network, refer to
Link Layer Discovery Protocol.
LLDP Commands
Monitor LLDP with the following commands. See the command line reference for additional options, definitions, and examples.
netq show lldp
netq show events message_type lldp
View LLDP in the UI
To add the LLDP card to your workbench, navigate to the header and select Add card >Network services >All LLDP Sessions card > Open cards. In this example, there are 25 nodes running the LLDP protocol, 184 established sessions, and no LLDP-related events from the past 24 hours:
Expand to the large card for additional LLDP information. This view displays the number of missing neighbors and how that number has changed over time. This is a good indicator of link communication issues. This info is displayed in the bottom chart, under Total sessions with no NBR. The right half of the card displays the switches handling the most LLDP traffic. Select the dropdown to view switches with unestablished LLDP sessions.
Expand the LLDP card to full-screen to view, filter, or export:

Peer information and attributes
From this table, you can select a row, then click Add card above the table.
NetQ adds a new, LLDP ‘single-session’ card to your workbench.
Monitor a Single LLDP Session
From the LLDP single-session card, you can view the number of nodes running the LLDP service, view neighbor state changes, and monitor the running LLDP configuration and any changes to the configuration file. This view is helpful for determining the stability of the LLDP session between two devices.
Understanding the Heat Map
On the medium and large single-session cards, vertically stacked heat maps represent the status of the neighboring peers: 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 appear by how saturated the color is for each block. If LLDP detected all peers during that time period for the entire time block, then the top block is 100% saturated (white) and the neighbor not detected block is 0% saturated (gray). As peers become reachable, the neighbor-detected block increases in saturation and the peers that are unreachable (neighbor not detected) block is proportionally reduced in saturation. The following table lists the most common time periods, their corresponding number of blocks, and the amount of time represented by one block:

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 lets you compare it with the last version using the NetQ UI. This can be useful when you are troubleshooting potential causes for alarms or sessions losing their connections.
From the large single-session card, select the Configuration file evolution tab.
Select the time.
Choose between the File view and the Diff view.
The File view displays the content of the file:
The Diff view highlights the changes (if any) between this version (on left) and the most recent version (on right) side by side:
MAC Addresses
A MAC (media access control) address is a layer 2 construct that uses 48 bits to uniquely identify a network interface controller (NIC) for communication within a network.
With NetQ, you can:
View MAC address across the network and for a given device, VLAN, egress port on a VLAN, and VRR
View a count of MAC addresses on a given device
View where MAC addresses have lived in the network (MAC history)
View commentary on changes to MAC addresses (MAC commentary)
View events related to MAC addresses
MAC addresses are associated with switch interfaces. They are classified as:
Origin: MAC address is owned by a particular switch, on one or more interfaces. A MAC address typically has only one origin node. The exceptions are when MLAG is configured, the MAC on the VRR interfaces for the MLAG pair is the same, and when EVPN is configured, the MAC is distributed across the layer 3 gateways.
Remote: MAC address is learned or distributed by the control plane on a tunnel interface pointing to a particular remote location. For a given MAC address and VLAN there is only one first-hop switch (or switch pair), but multiple nodes can have the same remote MAC address.
Local (not origin and not remote): MAC address is learned on a bridge and points to an interface on another switch. If the LLDP neighbor of the interface is a host, then this switch is the first-hop switch where the MAC address is learned. For a given MAC address and VLAN there is only one first-hop switch, except if the switches are part of an MLAG pair, and the interfaces on both switches form a dually or singly connected bond.
The NetQ UI provides a listing of current MAC addresses that you can filter by hostname, timestamp, MAC address, VLAN, and origin. You can sort the list by these parameters and also remote, static, and next hop.
Monitor MAC addresses with the following commands. Refer to the command line reference for additional options, definitions, and examples.
netq show macs
netq <hostname> show macs egress-port <egress-port>
netq show mac-history <mac>
netq show mac-commentary <mac> vlan <1-4096>
netq show events message_type macs
View MAC Addresses Networkwide
You can view all MAC addresses across your network with the NetQ UI or the NetQ CLI.
Select the Menu.
Under the Network section, select MACs.
Use the netq show macs command to view all MAC addresses.
This example shows all MAC addresses in the Cumulus Networks reference topology.
cumulus@switch:~$ netq show macs

View MAC Addresses Associated with VRR Configurations
You can view all MAC addresses associated with your VRR (virtual router reflector) interface configuration using the netq show interfaces type macvlan command. This is useful for determining if the specified MAC address inside a VLAN is the same or different across your VRR configuration.
cumulus@switch:~$ netq show interfaces type macvlan

View the History of a MAC Address
It is useful when debugging to be able to see whether a MAC address is learned, 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 made chronologically.
Changes made between two points in time, using the between option.
Only the differences in the changes between two points in time using the diff option.

View MAC Address Commentary
You can get more descriptive information about changes to a given MAC address on a specific VLAN. Commentary is available for the following MAC address-related events based on their classification (refer to the definition of these at the beginning of this topic):
Event Triggers
Example Commentary
A MAC address is created, or the MAC address on the interface is changed via the hwaddress option in /etc/network/interface
leaf01 00:00:5e:00:00:03 configured on interface vlan1000-v0
An interface becomes a slave in, or is removed from, a bond

leaf04 (and MLAG peer leaf05): 44:38:39:00:00:5d learned on first hop switch, pointing to local interface bond4
A local MAC address is flushed or expires
leaf04 (and MLAG peer leaf05) 44:38:39:00:00:5d is flushed or expires from bond4
A local MAC address moves from one interface to another interface or to another switch
leaf04: 00:08:00:00:aa:13 moved from hostbond2 to hostbond3 00:08:00:00:aa:13 moved from hostbond2 to remote dest 27.0.0.13
To view MAC address commentary:
Select the Menu.
Under the Network heading, select MACs.
Select the checkbox next to one of the entries, then select Open card above the table.
Choose a time range, then click Continue.
You can scroll through the list to see comments related to the MAC address moves and changes:
(Optional) From here, you can filter the list by a given device by selecting Filters.
A red dot on the filter icon indicates that filtering is active. To remove the filter, click again, then click Clear Filter.
To see MAC address commentary, use the netq show mac-commentary command. The following examples show the commentary seen in common situations.
MAC Address Configured Locally
In this example, the 46:38:39:00:00:44 MAC address was configured on the VlanA-1 interface of multiple switches, so we see the MAC configured commentary on each of them.

MAC Address Configured on Server and Learned from a Peer
In this example, the 00:08:00:00:aa:13 MAC address was configured on server01. As a result, both leaf11 and leaf12 learned this address on the next hop interface serv01bond2 (learned locally), whereas, the leaf01 switch learned this address remotely on vx-34 (learned remotely).

MAC Address Moved on Server and Learned from a Peer
The MAC address on server11 changed from 00:08:00:00:aa:13. In this example, the MAC learned remotely on leaf01 is now a locally learned MAC address from its local interface swp6. Similarly, the locally learned MAC addresses on leaf11 and leaf12 are now learned from remote dest 27.0.0.22.

MLAG
You use Multi-Chassis Link Aggregation (MLAG) 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 have a connection 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, NetQ supports active-active links from the dual-connected devices even though each switch connects to a different physical switch. For an overview and how to configure MLAG in your network, refer to
Multi-Chassis Link Aggregation - MLAG.
MLAG or CLAG?
Other vendors refer to the Cumulus Linux implementation of MLAG as MLAG, MC-LAG or VPC. The NetQ UI uses the MLAG terminology predominantly. However, the management daemon, named clagd, and other options in the code, such as clag-id, remain for historical purposes.
MLAG Commands
Monitor MLAG with the following commands. See the command line reference for additional options, definitions, and examples.
netq show mlag
netq show events message_type mlag
The netq check mlag command verifies MLAG session consistency by identifying all MLAG peers with errors or misconfigurations in the NetQ domain.
netq check mlag
View MLAG in the UI
To add the MLAG card to your workbench, navigate to the header and select Add card > Network services > All MLAG Sessions card > Open cards. This example shows the following for the last 24 hours:
Four nodes have been running the MLAG protocol with no changes in that number
Four sessions were established and remained so
No MLAG-related events have occurred
Expand to the large card for additional MLAG info. By default, the card displays the Sessions summary tab. From here you can see which devices are handling the most MLAG sessions, or select the dropdown to view nodes with the most unestablished MLAG sessions. You can view MLAG-related events by selecting the Events tab.
Expand the MLAG card to full-screen to view, filter, or export:
the number of bonds with only a single link (single bond)
the number of bonds with two links (dual bonds)
whether MLAG sessions have been assigned a backup IP address
sessions with conflicted bonds (bonds that conflict with existing bond relationships)
the MLAG configuration for a given device
all MLAG-related events
the attributes of all switches running MLAG in your network
the attributes of all MLAG sessions in your network
From this table, you can select a row, then click Add card above the table.
NetQ adds a new, MLAG ‘single-session’ card to your workbench. From this card, you can monitor the number of nodes running the MLAG service, view switches with the most peers alive and not alive, and view events triggered by the MLAG service.
Monitor a Single MLAG Session
The MLAG single-session card displays a summary of the MLAG session. In this example, the leaf01 switch plays the primary role in this session with leaf02 and the session is in good health. The heat map tells us that the peer switch has been alive for the entire 24-hour period.
From this card, you can also view the node role, peer role and state, and MLAG system MAC address which identify the session in further detail.
Granularity of Data Shown Based on Time Period
On the medium and large single MLAG session cards, vertically stacked heat maps represent the status of the peers; 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 amount of saturation for each block indicates how many peers were alive. 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 amount of saturation diminishes proportionally for peers that are in the alive block. The following table lists the most common time periods, their corresponding number of blocks, and the amount of time represented by one block:

View Changes to the MLAG Service Configuration File
Each time a change is made to the configuration file for the MLAG service, NetQ logs the change and enables you to compare it with the last version using the NetQ UI. This can be useful when you are troubleshooting potential causes for alarms or sessions losing their connections.
From the large single-session card, select the MLAG Configuration File Evolution tab.
Select the time.
Choose between the File view and the Diff view.
The File view displays the content of the file:
The Diff view highlights the changes (if any) between this version (on left) and the most recent version (on right) side by side:
Network Topology
The network topology dashboard displays a visual representation of your network, showing connections and device information for all monitored nodes. The view allows you to understand your network’s architecture at a high-level, but also lets you isolate individual devices or sections.
The topology view has been redesigned to better accommodate larger networks with over 50 devices. This feature is in beta and feedback is welcome. You can still access the legacy topology view by following the instructions in the NetQ 4.7 documentation.
Access the Topology View
To open the topology view, click Topology in the workbench header. Select Topology Beta to open a full-screen view of your network topology. The UI displays the highest-level view of your network’s topology, showing devices as part of tiers corresponding to your network’s architecture.
The default view reflects the devices comprising the network. A two-tier architecture is made up of leaf and spine devices; a three-tier architecture is made up of leaf, spine, and super-spine devices. There is an additional ‘unclassified’ tier for devices that do not have a role assigned to them. If your devices appear in this tier, assign roles to them. Then return to the topology view and select Auto arrange.
Interact with the Topology
The topology screen features a main panel displaying tiers or, when zoomed in, the individual devices that comprise the tiers. You can zoom in or out of the topology via the zoom controls at the bottom-right corner of the screen, a mouse with a scroll wheel, or with a trackpad on your computer. You can also adjust the focus by clicking anywhere on the topology and dragging it with your mouse to view a different portion of the network diagram. Above the zoom controls, a smaller screen reflects a macro view of your network and helps with orienting, similar to mapping applications.
View Device and Link Data
Zoom in and select a device to open a side panel with additional statistics, including interfaces statistics, resource utilization, and events occurring on that device.
The following data is presented in the side panel for each selected device:
Node Data
Description
ASIC
Name of the ASIC used in the switch. A value of Cumulus Networks VX indicates a virtual machine.
NetQ Agent status
Operational status of the NetQ Agent on the switch (fresh or 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.
Interface statistics
Transmit and receive data.
Resource utilization
CPU, memory, and disk utilization.
Events
Warning and info events.
Hovering over a line highlights each end of the connection; the number embedded in the line displays the total number of links. Select the line to open a side panel with additional configuration data, which can be sorted by link pairs.
From the side panel, you can view the following data about links:
Link Data
Description
Source hostname
Switch where the connection originates
Source Interface
Port on the source switch used by the connection
Peer hostname
Switch where the connection ends
Peer interface
Port on the destination switch used by the connection
Rearrange and Edit the Topology
You can rearrange the topology’s tiers by selecting Edit at the top of the screen and dragging the tiers into different positions. Click Save to preserve the view or Reset to undo the changes. You can also move devices to other tiers or create new tiers by right-clicking on a device. Through this menu, you can move the device to a different tier or enforce the role's assignment and tier associated with that assignment.
This menu also displays options to move the device to the unclassified tier or to a new tier. In the example above, the topology consists of three tiers and an unclassified tier. By selecting Move to tier 4, NetQ creates a new tier and places the selected device within it.
Create Queries to View a Subset of Devices
You can create queries to segment a topology into smaller, more manageable parts. This can be especially helpful when you need to view a particular section of a very large topology. To create a query, select Queries on the left side of the screen, then Add query. The name of the query is pre-populated with a unique identifier that you can edit by selecting the field.
You can select between node_name and node_tier to display either a subsection of nodes based on their names or the tiers where they’re located, respectively. Select Add filter group to combine queries with logical operators. For example, the following filter group consists of two queries: one displaying any node containing the letters “tor” and of those nodes, those located in tier three:
Select the three-dot menu on a given query to either delete or remove the query.
Lifecycle Management
Using the NetQ UI or CLI, lifecycle management (LCM) allows you to:
Lifecycle management is enabled for on-premises deployments and disabled for cloud deployments by default. Contact your NVIDIA sales representative or submit a support ticket to activate LCM on cloud deployments.

To add the OSPF card to your workbench, navigate to the header and select Add card > Network services > All OSPF Sessions card > Open cards. In this example, there are 8 nodes running OSPF and no reported events.
Expand to the large card to display which switches are handling the most OSPF traffic. By default, the card displays the Sessions summary tab and lists switches with established sessions. Select the dropdown to view nodes with the most unestablished OSPF sessions. You can view OSPF-related events by selecting the Events tab.
Expand the OSPF card to full-screen to view, filter, or export all stored attributes of all switches and hosts running OSPF in your network.
From the table, you can select a row, then click Open card above the table. NetQ adds a new, OSPF ‘single-session’ card to your workbench. From this card, you can view session state changes and compare them with events, and monitor the running OSPF configuration and changes to the configuration file.
Monitor a Single OSPF Session
The OSPF single-session card displays the interface name, peer address, and peer ID that identifies the session. The heat map indicates the stability of the OSPF session between two devices over a period of time. In this example, the session has been established throughout the past 24 hours:
Understanding the Heat Map
On the medium and large single OSPF session cards, vertically stacked heat maps represent the status of the sessions; 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 appear 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 unestablished 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. The following example heat map is for a time period of 24 hours, with the most common time periods in the table showing the resulting time blocks.

To configure the NetQ Agent to start monitoring additional services, run netq config add agent services, specifying the services you want the agent to monitor in the command. Restart the agent, then run netq config show agent services to display a list of services that the NetQ Agent is monitoring for CPU and memory usage.
To stop the agent from monitoring a service run netq config del agent services. Some services and processes cannot be excluded from monitoring.
To actively monitor process-level CPU and memory utilization, you can create threshold-crossing rules. These rules generate events when a process or service exceeds the utilization limit you defined when creating the rule. Refer to the resource utilization table in the TCA Events Reference for service memory and service CPU utilization event IDs.
View Queue Lengths in Histograms
Monitoring queue lengths in your network’s fabric is useful for detecting microbursts which can lead to higher packet latency or buffer congestion. The
Cumulus Linux documentation provides a detailed description of ASIC monitoring, including example bin configurations and information on interpreting histogram queue lengths.
Queue length monitoring is supported on Spectrum switches running Cumulus Linux 5.1 and later. To display queue histogram data, you must set the snapshot file count to at least 120 when you are configuring ASIC monitoring, as described in the Snapshots section in the
ASIC monitoring configuration documentation.
The information available in the UI can also be displayed via the CLI with the netq show histogram command. To view queue histograms in the UI:
Expand the Menu. Under the traffic histograms section, select Queue histogram.
Devices are grouped according to their roles: superspine, leaf, spine, or exit. If you haven’t assigned roles to your devices, they appear as ‘unassigned.’
Each device is represented by a card that displays its hostname, the port with the longest queue length (displayed horizontally, divided into bins), standard deviation, P95 value across all ports (with an ASIC monitoring configuration), and average queue length. The data updates when you change the time parameters using the controls at the top of the screen. The values reflected in the bins are color-coded, with higher values displayed in darker colors and lower values in lighter colors. Hover over a bin to view its corresponding queue length count.
Select View more to open a dashboard that displays the full range of ports configured to send histogram data along with their associated devices, which are visible when you hover over a section with your cursor. From this view, you can compare devices against each other or the same devices over a different time period. For example, the following view displays switch r-qa-sw-eth-2231 with queue length data from the past minute in the top panel and the past 30 minutes in the bottom panel.
The y-axis represents bins 0 through 9. The hostname associated with the port is displayed on the x-axis.

Flow Analysis
Create a flow analysis to sample data from TCP and UDP flows in your environment and to review latency and buffer utilization statistics across network paths.
Flow analysis is supported on NVIDIA Spectrum-2 switches and later. It requires a switch fabric running Cumulus Linux version 5.0 or later.
You must enable Lifecycle Management (LCM) to run a flow analysis. If LCM is disabled, you will not see the flow analysis icon in the UI. LCM is enabled for on-premises deployments by default and disabled for cloud deployments by default. Contact your local NVIDIA sales representative or submit a support ticket to activate LCM on cloud deployments.
Create a New Flow Analysis
To start a new flow analysis, click the Flow analysis icon and select Create new flow analysis.
In the dialog, enter the application parameters, including the source IP address, destination IP address, source port, and destination port of the flow you wish to analyze. Select the protocol and VRF for the flow from the dropdown menus.
After you enter the application parameters, enter the monitor settings, including the sampling rate and time parameters.
If you attempt to run a flow analysis that includes switches assigned a default, unmodified access profile, the process will fail. Create a unique access profile (or update the default profile with unique credentials), then assign the profile to the switches you want to include in the flow analysis.
Running a flow analysis will affect switch CPU performance. For high-volume flows, set a lower sampling rate to limit switch CPU impact.
View Flow Analysis Data
After starting the flow analysis, a flow analysis card will appear on the NetQ Workbench.
View a previous flow analysis by selecting Flow analysis and View previous flow analysis.
Select View details next to the name of the flow analysis to display the analysis dashboard. You can use this dashboard to view latency and buffer statistics for the monitored flow. If bi-directional monitoring was enabled, you can view the reverse direction of the flow by selecting the icon. The following example shows flow data across a single path:
The dashboard header shows the monitored flow settings:
Flow Settings
Description
Lifetime
The lifetime of the flow analysis. This example completed in 11 minutes.
Source IP
The source IP address of the flow. In this example it is 10.1.100.125.
Destination IP
The destination IP address of the flow. In this example it is 10.1.10.105.
Source Port
The source port of the flow. In this example it displays N/A because it was not set.
Destination Port
The destination port of the flow. In this example it is 2222.
Protocol
The protocol of the monitored flow. In this example it is UDP.
Sampling Rate
The sampling rate of the flow. In this example it is low.
VRF
The VRF the flow is present in. In this example it is the default VRF.
Bi-directional Monitoring
This determines if the flow is monitored in both directions between the source IP address and the destination IP address. In this example it is enabled. Click to change the direction that is displayed.
Understanding the Flow Analysis Graph
The flow analysis graph is color coded relative to the values measured across devices. Lower values are displayed in green, and higher values are displayed in orange. The color gradient is displayed below the graph along with the low and high values from the collected flow data. Each hop in the path is represented in the graph with a vertical, gray-striped line labeled by hostname. The following example shows a single path:
The flow graph panel on the right side of the dashboard displays the devices along the selected path.
View Flow Latency
The latency measured by the flow analysis is the total transit time of the sampled packets through individual devices. A summary of measured latency for each device is displayed above the main flow analysis graph.
The average latency for packets in the flow is displayed under the hostname of each device, along with the minimum and maximum latencies observed during the analysis lifetime. The 95th percentile (P95) latency value for sampled packets is also displayed. The P95 calculation means that 95% of the sampled packets have a latency value less than or equal to the calculation.
Use your cursor to hover over sections of the main analysis graph to view average latency values for each device in a path.
The left panel of the flow analysis dashboard also displays a timeline of measured latency for each device on that path. Use your cursor to hover over the plotted data points on the timeline for each device to view the latency measured at each time interval.
View Buffer Occupancy
The main flow analysis dashboard also displays the buffer occupancy of each device along the path. To change the graph view to display buffer occupancy for the flow, click next to Avg. flow latency and select Avg. buffer occupancy. You can view an overview graph of buffer occupancy or select each device to see the buffer occupancy for the analyzed flow:
The percentages represent the amount of buffer space on the switch that the analyzed flow occupied while the analysis was running.
View Multiple Paths
When packets matching the flow settings traverse multiple paths in the topology, the flow graph displays latency and buffer occupancy for each path:
You can switch between paths by clicking on an alternate path in the Flow graph panel, or by clicking on an unselected path on the main analysis graph:
In the detail panel on the left side of the dashboard, you can select a path to view the percent of packets distributed over each path.
Partial Path Support
Some flows can still be analyzed if they traverse a network path that includes switches lacking flow analysis support. Partial-path flow analysis is supported in the following conditions:
The unsupported device cannot be the initial ingress or terminating egress device in the path of the analyzed flow.
If there is more than one consecutive transit device in the path that lacks flow analysis support, the path discovery will terminate at that point in the topology and some devices will not be displayed in the flow graph.
An unsupported device is represented in the flow analysis graph as a black bar lined with red x’s. Flow statistics are not displayed for that device.
Unsupported devices are also designated in the flow graph panel:
Selecting the unsupported device displays device statistics in the left panel if they are available to NetQ. Otherwise, the display will indicate why the device is not supported:
Path discovery will terminate if multiple consecutive switches do not support flow analysis. When additional data is available from switches outside of discovered paths, you can view data from those devices from the menu at the top of the page:
The left panel displays the data, along with ingress and egress ports.
View Device Statistics
You can view latency, buffer occupancy, interface statistics, resource utilization, and WJH events for each device by clicking on a device in the Flow Graph panel, or by clicking on the line associated with a device in the main flow analysis graph. The left panel will then update to reflect statistics for the respective device.
After selecting a device, click to expand the statistics chart:
In this view, you can select additional categories to add to the chart:
The Flow Graph panel allows you to access the topology view, where you can also click the paths and devices to view statistics. Click View in topology to switch to the topology view.
View WJH Events
Flow analysis monitors the path for WJH events and records any drops for the flow. Switches with WJH events recorded are represented in the flow analysis graph as a red bar with white stripes. Hover over the device to see a WJH event summary:
You can also view devices with WJH events in the flow graph panel:
Click on a device with WJH events to see the statistics in the left panel. Hover over the data to reveal the type of drops over time:
WJH drops can also be viewed from the expanded device chart by selecting the WJH category:
Select Show all drops to display a list of all WJH drops for the device:
Verify Network Connectivity
You can verify the connectivity between two devices in both an ad-hoc fashion and by defining connectivity checks to occur on a scheduled basis.
Specifying Source and Destination Values
When specifying traces, the following options are available for the source and destination values:
Trace Type
Source
Destination
Layer 2
Hostname
MAC address plus VLAN
Layer 2
IPv4/IPv6 address plus VRF (if not default)
MAC address plus VLAN
Layer 2
MAC Address
MAC address plus VLAN
Layer 3
Hostname
IPv4/IPv6 address
Layer 3
IPv4/IPv6 address plus VRF (if not default)
IPv4/IPv6 address
If you use an IPv6 address, you must enter the complete, non-truncated address.
Known Addresses
The tracing function only knows about previously learned addresses. If you find that a path is invalid or incomplete, ping the identified device so that its address becomes known.
Create On-demand Traces
You can view the current connectivity between two devices in your network by creating an on-demand trace. You can perform these traces at layer 2 or layer 3 using the NetQ UI or the NetQ CLI.
Create a Layer 3 On-demand Trace Request
It is helpful to verify the connectivity between two devices when you suspect an issue is preventing proper communication between them. If you cannot find a layer 3 path, you might also try checking connectivity through a layer 2 path.
Determine the IP addresses of the two devices you want to trace.
Click Menu, then select IP addresses.
Select Filter and enter a hostname.
From the list of results, note the relevant address.
Filter the list again for the other hostname, and note its address.
Open the Trace Request card.
On a new workbench: Type trace in the Global search field and select the card.
On a current workbench: Click Add card, then select the Trace 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.
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.
Use the netq trace command to view the results in the terminal window. Use the netq add trace command to view the results in the NetQ UI.
To create a layer 3 on-demand trace and see the results in the terminal window, run:
Note the syntax requires the destination device address first and then the source device address or hostname.
This example shows a trace from 10.10.10.1 (source, leaf01) to 10.10.10.63 (destination, border01) on the underlay in pretty output. You could have used leaf01 as the source instead of its IP address. The example first identifies the addresses for the source and destination devices using netq show ip addresses then runs the trace.
cumulus@switch:~$ netq border01 show ip addresses

Each row of the pretty output shows one of the 12 available paths, with each path described by hops using the following format:
source hostname and source egress port – ingress port of first hop and device hostname and egress port – n*(ingress port of next hop and device hostname and egress port) – ingress port of destination device hostname
In this example, 8 of 12 paths use four hops to get to the destination and four use three hops. The overall MTU for all paths is 9216. No errors or warnings are present on any of the paths.
To create a layer 3 on-demand trace and see the results in the On-demand Trace Results card, run:
netq add trace <ip> from (<src-hostname> | <ip-src>) [alert-on-failure]
This example shows a trace from 10.10.10.1 (source, leaf01) to 10.10.10.63 (destination, border01).
Note the syntax requires the destination device address first and then the source device address or hostname.
This example shows a trace from 10.1.10.101 (source, server01) to 10.1.10.104 (destination, server04) through VRF RED in detail output. It first identifies the addresses for the source and destination devices and a VRF between them using netq show ip addresses then runs the trace. Note that the VRF name is case sensitive. The trace job might take some time to compile all the available paths, especially if there are many of them.
To create a layer 3 on-demand trace and see the results in the On-demand Trace Results card, run:
netq add trace <ip> from (<src-hostname> | <ip-src>) vrf <vrf>
This example shows a trace from 10.1.10.101 (source, server01) to 10.1.10.104 (destination, server04) through VRF RED.
cumulus@switch:~$ netq add trace 10.1.10.104 from 10.1.10.101 vrf RED
Create a Layer 2 On-demand Trace
It is helpful to verify the connectivity between two devices when you suspect an issue is preventing proper communication between them. If you cannot find a path through a layer 2 path, you might also try checking connectivity through a layer 3 path.
Note the syntax requires the destination device address first and then the source device address or hostname.
This example shows a trace from 44:38:39:00:00:32 (source, server01) to 44:38:39:00:00:3e (destination, server04) through VLAN 10 in detail output. It first identifies the MAC addresses for the two devices using netq show ip neighbors. Then it determines the VLAN using netq show macs. Then it runs the trace.
Use the netq add trace command to view on-demand trace results in the NetQ UI.
To create a layer 2 on-demand trace and see the results in the On-demand Trace Results card, run:
netq add trace <mac> vlan <1-4096> from <mac-src>
This example shows a trace from 44:38:39:00:00:32 (source, server01) to 44:38:39:00:00:3e (destination, server04) through VLAN 10.
cumulus@switch:~$ netq add trace 44:38:39:00:00:3e vlan 10 from 44:38:39:00:00:32
View On-demand Trace Results
After you have started an on-demand trace or run the netq add trace command, the results appear in either the UI or CLI. In the CLI, run the netq show trace results command. In the UI, locate the On-demand Trace Result card:
After you click Run now, the corresponding results card opens on your workbench. While it is working on the trace, a notice appears on the card indicating it is running. When it is finished, the results are displayed:

View Scheduled Trace Settings for a Given Trace
You can view the configuration settings used by a give scheduled trace using the netq show trace settings command.
This example shows the settings for the scheduled trace named Lf01toBor01Daily.
cumulus@switch:~$ netq show trace settings name Lf01toBor01Daily
View Scheduled Trace Results for a Given Trace
You can view the results for a give scheduled trace using the netq show trace results command.
This example obtains the job ID for the trace named Lf01toBor01Daily, then shows the results.
cumulus@switch:~$ netq show trace summary name Lf01toBor01Daily json
cumulus@switch:~$ netq show trace results f501f9b0-cca3-4fa1-a60d-fb6f495b7a0e
Modify a Scheduled Trace
You can modify scheduled traces at any time as described below. An administrator can also manage scheduled traces through the NetQ management dashboard.
Be aware that changing the configuration of a trace can cause the results to be inconsistent with prior runs of the trace. If this is an unacceptable result, create a new scheduled trace. Optionally you can remove the original trace.
To modify a scheduled trace:
Open the Trace Request card.
Select the trace from the New trace request dropdown.
Edit the schedule, VLAN, or VRF and select Update.
From the confirmation dialog, click Yes to complete the changes or select the link to change the name of the previous version of this scheduled trace.
The validation can now be selected from the New Trace listing and run immediately by selecting Go or Run now. Alternately, you can wait for it to run the first time according to the schedule you specified.
Remove Scheduled Traces
If you have reached the maximum of 15 scheduled traces for your premises, you will need to remove traces to create additional ones.
Both a standard user and an administrative user can remove scheduled traces. No notification is generated on removal. Be sure to communicate with other users before removing a scheduled trace to avoid confusion and support issues.
Open the Trace Request card and expand the card to the largest size.
Select one or more traces.
Above the table, select Delete.
Find the name of the scheduled trace you want to remove:
netq show trace summary [name <text-trace-name>] [around <text-time-hr>] [json]
The following example shows all scheduled traces in JSON format:
cumulus@switch:~$ netq del trace leaf01toborder01
Successfully deleted schedule trace leaf01toborder01
Repeat these steps to remove additional traces.

Generate a Support File on the NetQ System
The opta-support command generates information for troubleshooting issues with NetQ. It provides information about the NetQ Platform configuration and runtime statistics as well as output from the docker ps command.
cumulus@server:~$ sudo opta-support
Please send /var/support/opta_support_server_2021119_165552.txz to Nvidia support.
To export network validation check data in addition to OPTA health data to the support bundle, the NetQ CLI must be activated with AuthKeys. If the CLI access key is not activated, the command output displays a notification and data collection excludes netq show output:
cumulus@server:~$ sudo opta-support
Access key is not found. Please check the access key entered or generate a fresh access_key,secret_key pair and add it to the CLI configuration
Proceeding with opta-support generation without netq show outputs
Please send /var/support/opta_support_server_20211122_22259.txz to Nvidia support.
Generate a Support File on Switches and Hosts
The netq-support command generates information for troubleshooting NetQ issues on a host or switch. Similar to collecting a support bundle on the NetQ system, the NVIDIA support team might request this output to gather more information about switch and host status.
When you run the netq-support command on a switch running Cumulus Linux, a cl-support file will also be created and bundled within the NetQ support archive:
The following sections contain NetQ reference materials.
NetQ CLI Reference
This reference provides details about each of the NetQ CLI commands. For an overview of the CLI structure and usage, read the NetQ Command Line Overview.
The commands appear alphabetically by command name.
Because all commands begin with netq, the next required keyword determines the order
Punctuation and numbers appear before letters
When options are available, you should use them in the order listed.
Integrate NetQ API with Your Applications
The NetQ API provides data about the performance and operation of your network and its devices. You can view the data with your internal tools or with third-party analytic tools. The API displays the health of individual switches, network protocols and services, trace and validation results, as well as networkwide inventory and events.
This guide provides an overview of the NetQ API framework, including the basics of using Swagger UI 2.0 or bash plus curl to view and test the APIs. Descriptions of each endpoint and model parameter are in individual API JSON files.
Inventory and Devices: Address, Inventory, MAC Address tables, Node, Sensors
Events: Events
Each endpoint has its own API. You can make requests for all data and all devices or you can filter the request by a given hostname. Each API returns a predetermined set of data as defined in the API models.
The Swagger interface displays both public and internal APIs. Public APIs do not have internal in their name. Internal APIs are not supported for public use and subject to change without notice.
Get Started
You can access the API gateway and execute requests from the Swagger UI or a terminal interface. If you are using a terminal window, proceed to the next section.
Open the Swagger interface by entering one of the following in your browser’s address bar:
Select auth from the Select a definition dropdown at the top right of the window. This opens the authorization API.
Log In
Although you can view the API endpoints without authorization, you can only execute the API endpoints if you have been authorized.
You must first obtain an access key and then use that key to authorize your access to the API.
Click POST/login.
Click Try it out.
Enter the username and password you use to log in to the NetQ UI. Do not change the access-key value.
Click Execute.
Scroll down to view the Responses. In the Server response section, in the Response body of the 200 code response, copy the access token in the top line.
Click Authorize.
Paste the access key into the Value field, and click Authorize.
Click Close.
To log in and obtain authorization:
Open a terminal window.
Log in to obtain the access token. You will need the following information:
Hostname or IP address, and port (443 for cloud deployments, 32708 for on-premises deployments) of your API gateway
Your login credentials that were provided as part of the NetQ installation process. For this release, the default is username admin and password admin.
This example uses an IP address of 192.168.0.10, port of 443, and the default credentials:
The output provides the access token as the first parameter.
{"access_token":"eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9....","customer_id":0,"expires_at":1597200346504,"id":"admin","is_cloud":true,"premises":[{"name":"OPID0","namespace":"NAN","opid":0},{"name":"ea-demo-dc-1","namespace":"ea1","opid":30000},{"name":"ea-demo-dc-2","namespace":"ea1","opid":30001},{"name":"ea-demo-dc-3","namespace":"ea1","opid":30002},{"name":"ea-demo-dc-4","namespace":"ea1","opid":30003},{"name":"ea-demo-dc-5","namespace":"ea1","opid":30004},{"name":"ea-demo-dc-6","namespace":"ea1","opid":30005},{"name":"ea-demo-dc-7","namespace":"ea1","opid":80006},{"name":"Cumulus Data Center","namespace":"NAN","opid":1568962206}],"reset_password":false,"terms_of_use_accepted":true}
Copy the access token to a text file. You will need this token to make API data requests.
You are now able to create and execute API requests against the endpoints.
By default, authorization is valid for 24 hours, after which users must sign in again and reauthorize their account.
API Requests
You can use either the Swagger UI or a terminal window with bash and curl commands to create and execute API requests.
Select the endpoint from the definition dropdown at the top right of the application.
This example shows the BGP endpoint selected:
Select the endpoint object.
This example shows the results of selecting the GET bgp object:
A description is provided for each object and the various parameters that can be specified. In the Responses section, you can see the data that is returned when the request is successful.
Click Try it out.
Enter values for the required parameters.
Click Execute.
In a terminal window, use bash plus curl to execute requests. Each request contains an API method (GET, POST, etc.), the address and API endpoint object to query, a variety of headers, and sometimes a body. For example, in the log in step above:
API method = POST
Address and API object = “https://<netq.domain>:443/netq/auth/v1/login”
Headers = -H “accept: application/json” and -H “Content-Type: application/json”
Body = -d “{ "username": "admin", "password": "admin", "access_key": "string"}”
API Responses
A NetQ API response comprises 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 might not have the 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
Unexpected condition has occurred.
Perform general troubleshooting and try the request again.
503
Service Unavailable
The service being requested is currently unavailable.
Verify the status of the NetQ Platform or appliance, and the associated service.
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. When using the curl commands, the responses have been piped through a python tool to make them more readable. You can choose to do so as well.
Validate Networkwide Status of the BGP Service
Make your request to the bgp endpoint to obtain validate the operation of the BGP service on all nodes running the service.
Open the check endpoint.
Open the check object.
Click Try it out.
Enter values for time, duration, by, and proto parameters.
In this example, time=1597256560, duration=24, by=scheduled, and proto=bgp.
Click Execute, then scroll down to see the results under Server response.
Run the following curl command, entering values for the various parameters. In this example, time=1597256560, duration=24 (hours), by=scheduled, and proto=bgp.
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:
