Displaying UDLD Information
Displaying Information for All Ports
To display UDLD information for all ports, enter the following command:
Syntax:
show link-keepalive [ethernet [<slotnum>/]<portnum>]
If a port is disabled by UDLD, the change also is indicated in the output of the
show interfaces brief
command.
Here is an example:
If the port was already down before you enabled UDLD for the port, the port’s state is listed as None.
Syntax:
show interface brief
