282 BigIron RX Series Configuration Guide53-1001986-01Displaying UDLD information10If a port is disabled by UDLD, the change also is indicated in the output of the show interfaces briefcommand. Here is an example.If the port was already down before you enabled UDLD for the port, the port’s state is listed asNone.Syntax: show interface briefThe “show interfaces brief" is an abbreviation of "show ip interfaces brief". The "ip" is implied. If a veinterface has no IP address and only an address in a different protocol, "show interfaces brief" willshow the interface as down. This is by design. To view ve interface status in relation to protocolsother than IP, please specifify the protocol. For example, "show ipx interface ve " or "showappletalk interface ve ".The show link-keepalive command shows the following.Syntax: show link-keepalive ethernetDisplaying information for a single portTo display detailed UDLD information for a specific port, enter a command such as the following.TABLE 62 CLI display of UDLD informationThis 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 beforeconcluding 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 portand 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 thisBigIron RX port and the BigIron RX port on the other end of the link. If thestates of both Physical Link and Link-keepalive are up, then Logical link isup. If either or both Physical Link and Link-keepalive states are down, thenLogical Link displays "down".BigIron RX(config)# show interface briefPort Link State Dupl Speed Trunk Tag Priori MAC Name1/1 Up LK-DISABLE None None None No level0 00e0.52a9.bb001/2 Down None None None None No level0 00e0.52a9.bb011/3 Down None None None None No level0 00e0.52a9.bb021/4 Down None None None None No level0 00e0.52a9.bb03BigIron RX(config)# show link-keepalive ethernetCurrent State : down Remote MAC Addr : 0000.0000.0000Local Port : 1/1 Remote Port : n/aLocal System ID : e0eb8e00 Remote System ID : 00000000Packets sent : 0 Packets received : 0Transitions : 0
