Configuring the MAC Address-Table Move Update Feature
This section describes the following tasks:
• Configuring a Switch to Send MAC Address-Table Move Updates, page 24-10
• Configuring a Switch to Receive MAC Address-Table Move Updates, page 24-11
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:
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
Command Purpose
Step 1
Switch# configure terminal
Enters global configuration mode.
Step 2
Switch(conf)# interface interface-id
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.
Step 3
Switch(conf-if)# switchport backup interface
interface-id
or
Switch(conf-if)# switchport backup interface
interface-id mmu primary vlan vlan-id
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.
Step 4
Switch(conf-if)# end
Returns to global configuration mode.
Step 5
Switch(conf)# mac address-table move update
transmit
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.
Step 6
Switch(conf)# end
Returns to privileged EXEC mode.
Step 7
Switch# show mac address-table move update
Verifies the configuration.
Step 8
Switch# copy running-config startup config
(Optional) Saves your entries in the switch startup
configuration file.
