The MAC moves mechanism detects when a MAC address migrates from one port to another port, such as:
When a MAC address migrates from one port to another port, the new EAPoL-enabled port triggers a new RADIUS authentication. New bindings are applied on the new EAPoL-enabled port. The old port detects the MAC is moved and automatically deletes the old binding or bindings.
The Mac moves mechanism works between vIST peers when a MAC address on one peer migrates to the other peer but only if the I-SID in which the MAC address is learned exists on the new and the old peer.
