Chapter 20 Configuring Flex Links and the MAC Address-Table Move Update Feature
Configuring Flex Links and MAC Address-Table Move Update
To disable the MAC address-table move update feature, use the no mac address-table move update
transmit interface configuration command. To display the MAC address-table move update information,
use the show mac address-table move update privileged EXEC command.
This example shows how to configure an access switch to send MAC address-table move update
messages:
Switch# configure terminal
Switch(conf)# interface gigabitethernet1/0/1
Switch(conf-if)# switchport backup interface gigabitethernet0/2 mmu primary vlan 2
Switch(conf-if)# exit
Switch(conf)# mac address-table move update transmit
Switch(conf)# end
This example shows how to verify the configuration:
Switch# show mac-address-table move update
