BigIron RX(config)#sh link-keepalive
Total link-keepalive enabled ports: 2
Keepalive Retries: 5 Keepalive Interval: 5 * 100 MilliSec.
Port Physical Link Link-keepalive Logical link
1/15 up init up
2/15 up init up
Syntax: show link-keepalive
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
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 show link-keepalive command shows the following.
TABLE 65 CLI display of UDLD information
This field... Displays...
Total link-keepalive enabled ports The total number of ports on which UDLD is enabled.
Keepalive Retries The number of times a port will attempt the health check before
concluding that the link is down.
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 BigIron RX 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
BigIron RX port and the BigIron RX 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".
