Configuring FlexLinks and the MAC Address-Table Move Update
Configuration Examples for the FlexLinks and MAC Address-Table Move Update
When a FlexLinks interface comes up, VLANs preferred on this interface are blocked on the peer interface and moved
to the forwarding state on the interface that has just come up. In this example, if interface Gigabit Ethernet1/1 comes up,
VLANs preferred on this interface are blocked on the peer interface Gigabit Ethernet1/2 and forwarded on Gigabit
Ethernet1/1.

Configuring MAC Address-Table Move Update: Example
This example shows how to configure an access switch to send MAC address-table move update messages:
Switch(conf)# interface GigabitEthernet1/17
Switch(conf-if)# switchport backup interface GigabitEthernet1/18 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:
