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

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

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

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

View Devices with the Most Layer 2 EVPN Sessions
You can view the number layer 2 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 is expected based on your network design, and compare that with data from an earlier time to look for any differences.
To view switches and hosts with the most layer 2 EVPN sessions:
-
Open the large Network Services|All EVPN Sessions card.
-
Select Switches with Most L2 EVPN from the filter above the table.
The table content is sorted by this characteristic, listing nodes running the most layer 2 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 2 EVPN sessions, run netq show evpn, then count the layer 2 sessions.
In this example, border01 and border02 have no layer 2 sessions. The leaf01-04 switches each have three layer 2 sessions. Therefore the leaf switches have the most layer 2 sessions.

To compare this with a time in the past, run netq show evpn around.
In this example, border01 and border02 each have three layer 2 sessions. Leaf01-04 also have three layer 2 sessions. Therefore no switch has any more layer 2 sessions than any other running the EVPN service 14 days ago.

View Devices with the Most EVPN-related Alarms
Switches experiencing a large number of EVPN alarms may indicate a configuration or performance issue that needs further investigation. You can view the switches sorted by the number of EVPN alarms and then use the Switches card workflow or the Events|Alarms card workflow to gather more information about possible causes for the alarms.
You can view the switches sorted by the number of EVPN alarms and then use the Switches card workflow or the Events|Alarms card workflow to gather more information about possible causes for the alarms.
To view switches with the most EVPN alarms:
-
Open the large Network Services|All EVPN Sessions card.
-
Hover over the header and click
. -
Select Events by Most Active Device from the filter above the table.
The table content is sorted by this characteristic, listing nodes with the most EVPN alarms at the top. Scroll down to view those with the fewest alarms.
Where to go next depends on what data you see, but a few options include:
- Hover over the Total Alarms chart to focus on the switches exhibiting alarms during that smaller time slice. The table content changes to match the hovered content. Click on the chart to persist the table changes.
- Change the time period for the data to compare with a prior time. If the same switches are consistently indicating the most alarms, you might want to look more carefully at those switches using the Switches card workflow.
- Click Show All Sessions to investigate all EVPN sessions networkwide in the full screen card.
To view the switches with the most EVPN alarms and informational events, run the netq show events command with the type option set to evpn, and optionally the between option set to display the events within a given time range. Count the events associated with each switch.
In this example, all EVPN events in the last 24 hours are displayed:
cumulus@switch:~$ netq show events type evpn
No matching event records found
This example shows all EVPN events between now and 30 days ago.
cumulus@switch:~$ netq show events type evpn between now and 30d
No matching event records found
View All EVPN Events
The Network Services|All EVPN Sessions card workflow and the netq show events type evpn command enable you to view all of the EVPN events in a designated time period.
To view all EVPN events:
-
Open the full screen Network Services|All EVPN Sessions card.
-
Click All Alarms tab in the navigation panel. By default, events are sorted by Time, with most recent events listed first.
Where to go next depends on what data you see, but a few options include:
- Open one of the other full screen tabs in this flow to focus on devices or sessions.
- Sort by the Message or Severity to narrow your focus.
- Export the data for use in another analytics tool, by selecting all or some of the events and clicking
. - Click
at the top right to return to your workbench.
To view all EVPN alarms, run:
netq show events [level info | level error | level warning | level critical | level debug] type evpn [between <text-time> and <text-endtime>] [json]
Use the level option to set the severity of the events to show. Use the between option to show events within a given time range.
This example shows critical EVPN events in the past three days.
cumulus@switch:~$ netq show events level critical type evpn between now and 3d
