statistics

on page 205.

The following table describes the information displayed by the show lldp statistics command.

Field

Description

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.
