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

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
