Chapter 2 Catalyst 3560 Switch Cisco IOS Commands show udld Table 2-32 show udld Field Descriptions Field Interface Port enable administrative configuration setting Port enable operational state Current bidirectional state Current operational state Message interval Time out interval Entry 1 Expiration time Device ID Current neighbor state Device name Port ID Neighbor echo 1 device Neighbor echo 1 port Message interval CDP device name Description The interface on the local device configured for UDLD. How UDLD is configured on the port. If UDLD is enabled or disabled, the port enable configuration setting is the same as the operational enable state. Otherwise, the enable operational setting depends on the global enable setting. Operational state that shows whether UDLD is actually running on this port. The bidirectional state of the link. An unknown state appears if the link is down or if it is connected to an UDLD-incapable device. A bidirectional state appears if the link is a normal two-way connection to a UDLD-capable device. All other values mean miswiring. The current phase of the UDLD state machine. For a normal bidirectional link, the state machine is most often in the Advertisement phase. How often advertisement messages are sent from the local device. Measured in seconds. The time period, in seconds, that UDLD waits for echoes from a neighbor device during the detection window. Information from the first cache entry, which contains a copy of echo information received from the neighbor. The amount of time in seconds remaining before this cache entry is aged out. The neighbor device identification. The neighbor's current state. If both the local and neighbor devices are running UDLD normally, the neighbor state and local state should be bidirectional. If the link is down or the neighbor is not UDLD-capable, no cache entries appear. The device name or the system serial number of the neighbor. The system serial number appears if the device name is not set or is set to the default (Switch). The neighbor port ID enabled for UDLD. The device name of the neighbors' neighbor from which the echo originated. The port number ID of the neighbor from which the echo originated. The rate, in seconds, at which the neighbor is sending advertisement messages. The CDP device name or the system serial number. The system serial number appears if the device name is not set or is set to the default (Switch). 78-16405-05 Catalyst 3560 Switch Command Reference 2-529
