Chapter 21 Configuring Flex Links and the MAC Address-Table Move Update Feature
Configuring Flex Links and MAC Address-Table Move Update
Beginning in privileged EXEC mode, follow these steps to configure an access switch to send MAC
address-table move updates:
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
Command Purpose
Step 1 configure terminal Enter global configuration mode.
Step 2 interface interface-id Specify the interface, and enter interface configuration
mode. The interface can be a physical Layer 2 interface or
a port channel (logical interface). The port-channel range
is 1 to 48.
Step 3 switchport backup interface interface-id
or
switchport backup interface interface-id mmu
primary vlan vlan-id
Configure a physical Layer 2 interface (or port channel),
as part of a Flex Link pair with the interface. The MAC
address-table move update VLAN is the lowest VLAN ID
on the interface.
Configure a physical Layer 2 interface (or port channel)
and specify 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
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.
