Chapter21 Configuring Flex Links and the MAC Address-Table Move Update Feature
Configuring Flex Links and the MAC Address-Table Move Update
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 gigabitethernet1/0/1
Switch(conf-if)# switchport backup interface gigabitethernet1/0/2 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
Rcv packet count this min : 0
Rcv threshold exceed count : 0
Rcv last sequence# this min : 0
Rcv last interface : Po2
Rcv last src-mac-address : 000b.462d.c502
Rcv last switch-ID : 0403.fd6a.8700
Xmt packet count : 0
Xmt packet count this min : 0
Xmt threshold exceed count : 0
Xmt pak buf unavail cnt : 0
Xmt last interface : None
Beginning in privileged EXEC mode, follow these steps to configure a switch to get and process MAC
address-table move update messages:
Step4 end Return to global configuration mode.
Step5 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.
Step6 end Return to privileged EXEC mode.
Step7 show mac address-table move update Verify the configuration.
Step8 copy running-config startup config (Optional) Save your entries in the switch startup
configuration file.
