Enabling ARP fast update for MAC address
moves
ARP fast update for MAC address moves allows the device to update an ARP entry immediately after
the outgoing interface for a MAC address changes. This feature ensures data connection without
interruption.
This feature takes effect only on intra-card MAC address moves.
As shown in
When the AP to which the user connects changes, the switch updates the ARP entry for the user
