LLDP neighbors
The show lldp neighbors command displays a list of the current LLDP neighbors per port.
The following shows an example report.
Syntax: show lldp neighbors
The following table describes the information displayed by the show lldp neighbors command.
Table 3:
This field... Displays...
Last neighbor change
time
The elapsed time (in hours, minutes, and seconds) since a neighbor last advertised
information. For example, the elapsed time since a neighbor was last added, deleted, or
its advertised information changed.
Neighbor entries added The number of new LLDP neighbors detected since the last reboot or since the last time
the clear lldp statistics all command was issued.
Neighbor entries
deleted
The number of LLDP neighbors deleted since the last reboot or since the last time the
clear lldp statistics all command was issued.
Neighbor entries aged
out
The number of LLDP neighbors dropped on all ports after the time-to-live expired.
Note that LLDP entries age out naturally when a port cable or module is disconnected or
when a port becomes disabled. However, if a disabled port is re-enabled, the system will
delete the old LLDP entries.
Neighbor
advertisements
dropped
The number of valid LLDP neighbors the device detected, but could not add. This can
occur, for example, when a new neighbor is detected and the device is already
supporting the maximum number of neighbors possible. This can also occur when an
LLDPDU is missing a mandatory TLV or is not formatted correctly.
Port The local port number.
Tx Pkts Total The number of LLDP packets the port transmitted.
Rx Pkts Total The number of LLDP packets the port received.
Rx Pkts w/Errors The number of LLDP packets the port received that have one or more detectable errors.
Rx Pkts Discarded The number of LLDP packets the port received then discarded.
Rx TLVs Unrecognz The number of TLVs the port received that were not recognized by the LLDP local agent.
Unrecognized TLVs are retained by the system and can be viewed in the output of the
show LLDP neighbors detail command or retrieved through SNMP.
Rx TLVs Discarded The number of TLVs the port received then discarded.
Neighbors Aged Out The number of times a neighbor information was deleted because its TTL timer expired.
