Chapter 21 Configuring Flex Links and the MAC Address-Table Move Update Feature

Configuring Flex Links and MAC Address-Table Move Update

	Command	Purpose
Step 4
	end	Return to global configuration mode.
Step 5
	mac address-table move update transmit	Enable the access switch to send MAC address-table
		move updates to other switches in the network if the
		primary link goes down and the switch starts forwarding
		traffic through the standby link.
Step 6
	end	Return to privileged EXEC mode.
Step 7 show mac address-table move update		Verify the configuration.
Step 8
	copy running-config startup config	(Optional) Save your entries in the switch startup
		configuration file.

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

Switch-ID : 010b.4630.1780

Dst mac-address : 0180.c200.0010

Beginning in privileged EXEC mode, follow these steps to configure a switch to get and process MAC address-table move update messages:

	Command		Purpose
Step 1
	configure terminal		Enter global configuration mode.
Step 2
	mac address-table move update receive		Enable the switch to get and process the MAC
			address-table move updates.
