Configuring Flex Links and the MAC Address-Table Move Update Feature
Beginning in privileged EXEC mode, follow these steps to configure an access switch to send MAC
address-table move updates:
Command
Step 1
configure terminal
Step 2
interface interface-id
Step 3
switchport backup interface interface-id
or
switchport backup interface interface-id mmu
primary vlan vlan-id
Step 4
end
Step 5
mac address-table move update transmit
Step 6
end
Step 7
show mac address-table move update
Step 8
copy running-config startup config
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 gigabitethernet0/21
Switch(conf-if)# switchport backup interface gigabitethernet0/22 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
Vlans/Macs supported : 1023/8320
Default/Current settings: Rcv Off/On, Xmt Off/On
Max packets per min : Rcv 40, Xmt 60
Rcv packet count : 5
Rcv conforming packet count : 5

Configuring Flex Links and MAC Address-Table Move Update
Purpose
Enter global configuration mode.
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.
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.
Return to global configuration mode.
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.
Return to privileged EXEC mode.
Verify the configuration.
(Optional) Save your entries in the switch startup
configuration file.
