Impact on the System

After the number of MAC addresses in an EVPN instance exceeds the upper limit, additional MAC addresses can still be added, and temporarily no MAC address loss or traffic interruption occurs.

Possible Causes

The number of MAC addresses in the EVPN instance exceeded the upper limit configured using the mac threshold-alarm upper-limit upper-limit-value lower-limit lower-limit-value command.

Procedure

1. Run the display evpn mac routing-table evpn-instance vpn-instance-name command to check whether the number of MAC addresses in the EVPN instance exceeds the upper limit.

2. Check whether the number of MAC addresses displayed in the command output is consistent with the MAC address or entry count displayed in the command output.

If they are consistent, go to Step 4.
If they are inconsistent, go to Step 3.

3. Delete excess MAC addresses and check whether the alarm is cleared.

If the alarm persists, go to Step 4.
If the alarm is cleared, go to Step 7.

4. Run the display evpn mac routing-table limit { all-evpn-instance | evpn-instance vpn-instance-name } command to check whether the number of current MAC addresses exceeds the upper limit.

If the number does not exceed the upper limit, go to Step 6.
If the number exceeds the upper limit, go to Step 5.

5. Run the mac threshold-alarm upper-limit upper-limit-value lower-limit lower-limit-value command in the EVPN instance view to reconfigure the upper MAC address limit and then go to Step 7.

6. Collect alarm information and configuration information, and then contact technical support personnel.

7. End.
