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

Vlans/Macs supported : 1023/8320
