EVPN
NetQ enables operators to view the health of the EVPN service on a networkwide and a per-session basis, giving greater insight into all aspects of the service. You accomplish this through two card workflows, one for the service and one for the session, and in the NetQ CLI with the netq show evpn command.
Monitor the EVPN Service Networkwide
View the EVPN Service Status
You can view the configuration and status of your EVPN overlay across your network or for a particular device from the NetQ UI or the NetQ CLI.
Open the small Network Services/All EVPN Sessions card. In this example, the number of devices running the EVPN service is six (6) and the number and distribution of related critical severity alarms is zero (0).
To view EVPN service status, run netq show evpn. The example below shows the configuration and status for all devices, including the associated VNI, VTEP address, the import and export route (showing the BGP ASN and VNI path), and the last time a change occurred for each device running EVPN. Use the hostname option to view the configuration and status for a single device.
This example shows the Cumulus reference topology, where EVPN runs on all border and leaf switches. Each session is represented by a single row.
cumulus@switch:~$ netq show evpn

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

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

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

View Devices with the Most Layer 3 EVPN Sessions
You can view the number layer 3 EVPN sessions on your switches and hosts using the large Network Services/All EVPN Sessions card and the NetQ CLI. This data enables you to see which switches are handling the most EVPN traffic currently, validate that is what you expect based on your network design, and compare that with data from an earlier time to look for any differences.
To view switches and hosts with the most layer 3 EVPN sessions:
-
Open the large Network Services/All EVPN Sessions card.
-
Select Switches with Most L3 EVPN from the filter above the table.
The table content is sorted by this characteristic, listing nodes running the most layer 3 EVPN sessions at the top. Scroll down to view those with the fewest sessions.
To compare this data with the same data at a previous time:
-
Open another large Network Services/All EVPN Sessions card.
-
Move the new card next to the original card if needed.
-
Change the time period for the data on the new card by hovering over the card and clicking
. -
Select the time period that you want to compare with the current time.
You can now see whether there are significant differences between this time period and the previous time period.
If the changes are unexpected, you can investigate further by looking at another timeframe, determining if more nodes are now running EVPN than previously, looking for changes in the topology, and so forth.
To determine the devices with the most layer 3 EVPN sessions, run netq show evpn, then count the layer 3 sessions.
In this example, border01 and border02 each have two layer 3 sessions. The leaf01-04 switches also each have two layer 3 sessions. Therefore there is no particular switch that has the most layer 3 sessions.

View Devices with the Most EVPN-related Alarms
Switches experiencing a large number of EVPN alarms can indicate a configuration or performance issue that needs further investigation. You can view the switches sorted by the number of EVPN alarms and then use the Switches card workflow or the Events|Alarms card workflow to gather more information about possible causes for the alarms.
You can view the switches sorted by the number of EVPN alarms and then use the Switches card workflow or the Events|Alarms card workflow to gather more information about possible causes for the alarms.
To view switches with the most EVPN alarms:
-
Open the large Network Services/All EVPN Sessions card.
-
Hover over the header and click
. -
Select Events by Most Active Device from the filter above the table.
The table content sorts by this characteristic, listing nodes with the most EVPN alarms at the top. Scroll down to view those with the fewest alarms.
Where to go next depends on what data you see, but a few options include:
- Hover over the Total Alarms chart to focus on the switches exhibiting alarms during that smaller time slice. The table content changes to match the hovered content. Click on the chart to persist the table changes.
- Change the time period for the data to compare with a prior time. If the same switches are consistently indicating the most alarms, you might want to look more carefully at those switches using the Switches card workflow.
- Click Show All Sessions to investigate all EVPN sessions networkwide in the full screen card.
To view the switches with the most EVPN alarms and informational events, run the netq show events command with the message_type option set to evpn, and optionally the between option set to display the events within a given time range. Count the events associated with each switch.
This example shows the events that have occurred in the last 48 hours.
