Enabling the Persistent MAC Address Feature: Example This example shows how to configure the persistent MAC address feature for a 7-minute time delay and to verify the configuration: Device(config)# stack-mac persistent timer 7 WARNING: The stack continues to use the base MAC of the old active WARNING: as the stack-MAC after a active switchover until the MAC WARNING: persistency timer expires. During this time the Network WARNING: Administrators must make sure that the old stack-mac does WARNING: not appear elsewhere in this network domain.
