Impact on the System

The card fails to execute the command.

Possible Causes

The Layer 2 user entries on the card are insufficient.


  1. Check whether some MAC addresses have been configured as BPDU MAC addresses using the bpdu mac-address command. If so, delete unnecessary BPDU MAC addresses to release entry resources used by BPDU MAC addresses.
  2. Check the VRRP configuration on the switch and delete unnecessary VRRP groups to release entry resources used by VRRP virtual MAC addresses.
  3. Check the interface configuration on the switch and delete unnecessary VLANIF interfaces and Layer 3 subinterfaces to release MAC address entry resources used by these interfaces.
  4. Release entry resources using the preceding steps, delete the globally delivered command that fails to be executed by the card in the system view, and then execute this command again.
  5. If the preceding steps cannot resolve the entry insufficiency issue, collect alarms, logs, and configurations on the switch and contact technical support personnel.
