Displaying information for a single port
To display detailed UDLD information for a specific port, enter a command such as the following.
The show interface ethernet <slot>/<portnum> command also displays the UDLD state for an
individual port. In addition, the line protocol state listed in the first line will say “down” if UDLD has
brought the port down. Here is an example:
BigIron RX(config)# show interface ethernet 1/1
