Switch#configure
Switch(config)#loopback-detection
Switch(config)#loopback-detection interval 30
Switch(config)#loopback-detection recovery-time 3
2) Enable loopback detection on ports 1/0/1-3 and set the process mode and recovery
mode.
Switch(config)#interface range gigabitEthernet 1/0/1-3
Switch(config-if-range)#loopback-detection
Switch(config-if-range)#loopback-detection config process-mode port-based
recovery-mode auto
Switch(config-if-range)#end
Switch#copy running-config startup-config
Verify the Configuration
Verify the global configuration:
Switch#show loopback-detection global
Loopback detection global status : enable
Loopback detection interval: 30 s
Loopback detection recovery time : 90 s
Verify the loopback detection configuration on ports:
Switch#show loopback-detection interface
