Usage Guidelines The MAC address-table move update feature allows the switch to provide rapid bidirectional
convergence if a primary (forwarding) link goes down and the standby link begins forwarding traffic.
You can configure the access switch to send the MAC address-table move update messages if the
primary link goes down and the standby link comes up. You can configure the uplink switches to receive
and process the MAC address-table move update messages.
