Displaying UDLD information
24
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
Displaying information for a single port
To display detailed UDLD information for a specific port, the command show link-keepalive ethernet
4/1 is valid for a port that is not configured for Tagged UDLD. For a Tagged UDLD port VLAN
information is also included. In the following example, port 1/1 is tagged in VLAN 2 and is
configured for tagged UDLD. Port 1/2 is not configured for tagged UDLD.

Keepalive Interval The number of seconds between health check packets.
Port The port number.
Physical Link The state of the physical link. This is the link between the Brocade port
and the directly connected device.
Link-keepalive Show if the keepalive link is up or down.
Logical Link The state of the logical link. This is the state of the link between this
device port and the device port on the other end of the link. If the states
of both Physical Link and Link-keepalive are up, then Logical link is up. If
either or both Physical Link and Link-keepalive states are down, then
Logical Link displays “down”.
