Displaying UDLD information
24
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.
In this example, the port has been brought down by UDLD. Notice that in addition to the information
in the first line, the port state on the fourth line of the display is listed as DISABLED.

This field...
Displays...
Current State
The state of the logical link. This is the link between this device port and
the device port on the other end of the link.
Remote MAC Addr
The MAC address of the port or device at the remote end of the logical
link.
Local Port
The port number on this router.
Remote Port
The port number on the router at the remote end of the link.
NOTE: The Remote Port number shown in this parameter reflects the
port ID sent by the other router or switch and interpreted by this
local router. In cases where this router interprets the port ID
different than the router that sent the port ID, the port shown
can be incorrect.
Local System ID
A unique value that identifies this router. The ID can be used by technical
support for troubleshooting.
Remote System ID
A unique value that identifies the router at the remote end of the link.
Packets sent
The number of UDLD health-check packets sent on this port.
Packets received
The number of UDLD health-check packets received on this port.
Transitions
The number of times the logical link state has changed between up and
down.
Link-vlan
The VLAN that the port is configured to tag the UDLD packets with.
