Chapter 16 Configuring Flex Links and the MAC Address-Table Move Update Feature Configuring Flex Links and 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: Step 1 Step 2 Command configure terminal 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 Step 7 Step 8 end show mac address-table move update copy running-config startup config 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. 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 OL-8915-01 Cisco Catalyst Blade Switch 3020 for HP Software Configuration Guide 16-7
