MAC address learning configuration notes and feature limitations

  • This command is not available on virtual routing interfaces. Also, if this command is configured on the LAG interface, MAC address learning will be disabled on all the ports in the LAG.
  • Entering the mac-learn-disable command on tagged ports disables MAC learning for that port in all VLANs to which that port is a member. For example, if tagged port 3/1/1 is a member of VLAN 10, 20, and 30 and you issue the mac-learn-disable command on port 3/1/1, port 3/1/1 will not learn MAC addresses, even if it is a member of VLAN 10, 20, and 30.
