Usage guidelines
The MAC authentication multi-VLAN mode prevents an authenticated online user from service
interruption caused by VLAN changes on a port. When the port receives a packet sourced from the
user in a VLAN not matching the existing MAC-VLAN mapping, the device neither logs off the user
nor reauthenticates the user. The device creates a new MAC-VLAN mapping for the user, and traffic
transmission is not interrupted. The original MAC-VLAN mapping for the user remains on the device
until it dynamically ages out. As a best practice, configure this feature on hybrid or trunk ports.
This feature improves transmission of data that is vulnerable to delay and interference. It is typically
applicable to IP phone users.
Examples
# Enable MAC authentication multi-VLAN mode on Ten-GigabitEthernet 1/0/1.
