module (e.g., 3/1 specifies port 1 on slot 3).

the same slot (e.g, 3/1-4 specifies ports 1-4 on slot 3).

• The UDLD protocol must be enabled before using this command.

• The UDLD protocol is not supported on aggregate ports.

• When two UDLD enabled ports that are configured in aggressive mode of operation gets the link-up 

asynchonously, then the UDLD port which gets the link-up indication first is considered to be in the 
shutdown state. In such case, the link should be configured manually after both the links are up to start 
UDLD detection.

• In case of faulty cable connection, the port which is configured in normal mode of operation is deter-

mined to be in the shutdown state.
