Displaying UDLD information
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.
BigIron RX(config)#sh link-keepalive
Total link-keepalive enabled ports: 2
Keepalive Retries: 5

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.
BigIron RX(config)# show interface brief
Port

1/2

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
The "show interfaces brief" is an abbreviation of "show ip interfaces brief". The "ip" is implied. If a ve
interface has no IP address and only an address in a different protocol, "show interfaces brief" will
show the interface as down. This is by design. To view ve interface status in relation to protocols
other than IP, please specifify the protocol. For example, "show ipx interface ve <num>" or "show
appletalk interface ve <num>".

The total number of ports on which UDLD is enabled.
The number of times a port will attempt the health check before
concluding that the link is down.
The number of seconds between health check packets.
The port number.
The state of the physical link. This is the link between the device port and
the directly connected device.
Show if the keepalive link is up or down.
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".
