Quick Steps for Configuring LBD
The following steps provide a quick tutorial on how to configure LBD. Each step describes a specific
operation and provides the CLI command syntax for performing that operation.
1 To enable the LBD protocol on a switch, use the loopback-detection command. For example:
-> loopback-detection enable
2 To enable the LBD protocol on a port, use the loopback-detection port command. For example:
-> loopback-detection port 1/1/2 enable
3 Configure the LBD transmission timer by using the loopback-detection transmission-timer
command. For example:
-> loopback-detection transmission-timer 200
4 To change the auto-recovery timer for Loopback detection, use the command loopback-detection
autorecovery-timer. By default, the violation recovery time is 300 seconds.
-> loopback-detection autorecovery-timer 600
Note. Once the default LBD is enabled on the switch, the remote-origin LBD can be configured. It can be
enabled globally or on a per port using the loopback-detection command with the remote-origin
parameter. For example:
-> loopback-detection remote-origin enable
-> loopback-detection port 1/1/2 remote-origin enable
Note. Optional. To verify the LBD global configuration use the show loopback-detection command or to
verify the LBD configuration on a port use the show loopback-detection port command. For example:
-> show loopback-detection
Global LBD Status : enabled,
Global Remote-origin LBD Status : enabled,
Global LBD Transmission Timer : 200 sec,
Global LBD Auto-recovery Timer : 600 sec,
-> show loopback-detection port 1/1/2
Global LBD Status : enabled,
Global Remote-origin LBD Status : enabled,
Global LBD Transmission Timer : 200 sec,
Global LBD Auto-recovery Timer : 600 sec,
Port LBD Status : enabled,
Port Remote-origin LBD Status : enabled,
Port LBD State : Inactive,
Port LBD Type : normal-edge,
To verify the LBD statistics of a port, use the show loopback-detection statistics port command. For
example:
-> show loopback-detection statistics port 1/1/2
LBD Port Statistics
