Configuration steps

Step 1 Create VLAN 3 and add Port 2 and Port 3 into VLAN 3.

Alpha-A28E#config

Alpha-A28E(config)#create vlan 3 active

Alpha-A28E(config)#interface port 2

Alpha-A28E(config-port)#switchport access vlan 3

Alpha-A28E(config-port)#exit

Alpha-A28E(config)#interface port 3

Alpha-A28E(config-port)#switchport access vlan 3

Alpha-A28E(config-port)#exit

Step 2 Enable loopback detection for the specified interface.

Alpha-A28E(config)#loopback-detection enable port-list 2-3

Alpha-A28E(config)#loopback-detection vlan 3

Alpha-A28E(config)#loopback-detection hello-time 3

Checking configurations

Use the show loopback-detection command to show interface loopback detection status.

Alpha-A28E#show loopback-detection port-list 2-3

Destination address: FFFF.FFFF.FFFF

VLAN:3
