Chapter 19 Configuring Flex Links and the MAC Address-Table Move Update Feature
Configuring Flex Links and the 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(conf)# interface gigabitethernet0/1
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
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
Rcv invalid packet count : 0
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 6.
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.
