Configuring a Switch to Send MAC Address-Table Move Updates
To configure an access switch to send MAC address-table move updates, perform this task:
Command
Step 1
Switch# configure terminal
Step 2
Switch(conf)# interface interface-id
Step 3
Switch(conf-if)# switchport backup interface
interface-id
or
Switch(conf-if)# switchport backup interface
interface-id mmu primary vlan vlan-id
Step 4
Switch(conf-if)# end
Step 5
Switch(conf)# mac address-table move update
transmit
Step 6
Switch(conf)# end
Step 7
Switch# show mac address-table move update
Step 8
Switch# copy running-config startup config
To disable the MAC address-table move update feature on the access switch, enter the
no mac address-table move update transmit interface configuration command. To display the MAC
address-table move update information, enter the show mac address-table move update command.
This example shows how to configure an access switch to send MAC address-table move update
messages and to verify the configuration:
Switch# configure terminal
Switch(conf)# interface fastethernet1/1
Switch(conf-if)# switchport backup interface fastethernet1/0/2 mmu primary vlan 2
Switch(conf-if)# end
Switch(conf)# mac address-table move update transmit
Switch(conf)# end
Switch# show mac-address-table move update

Chapter 24 Configuring Flex Links and MAC Address-Table Move Update
Purpose
Enters global configuration mode.
Specifies the interface, and enters interface configuration
mode. The interface might be a physical Layer 2 interface
or a port channel (logical interface). The port channel
range is 1 to 64.
Configures a physical Layer 2 interface (or port channel),
as part of a Flex Links pair with the interface. The MAC
address-table move update VLAN is the lowest VLAN ID
on the interface.
Configures a physical Layer 2 interface (or port channel)
and specifies the VLAN ID on the interface, which is used
for sending the MAC address-table move update.
When one link is forwarding traffic, the other interface is
in standby mode.
Returns to global configuration mode.
Enables the access switch to send MAC address-table
move updates to other switches in the network if the
primary link shuts down and the switch starts forwarding
traffic through the standby link.
Returns to privileged EXEC mode.
Verifies the configuration.
(Optional) Saves your entries in the switch startup
configuration file.
