Displaying LLDP Statistics

LLDP statistics are available on both a global and a per-port levels. Rebooting
the switch resets the LLDP statistics counters to zero. Disabling the transmit
and/or receive capability on a port "freezes" the related port counters at their
current values.
Syntax show lldp info stats [ port-list ]
The global LLDP statistics command displays an overview of
neighbor detection activity on the switch, plus data on the
number of frames sent, received, and discarded per-port. The
per-port LLDP statistics command enhances the list of per-port
statistics provided by the global statistics command with some
additional per-port LLDP statistics.
Global LLDP Counters:
Neighbor Entries List Last Updated: Shows the elapsed time since
a neighbor was last added or deleted.
New Neighbor Entries Count: Shows the total of new LLDP neigh­
bors detected since the last swtich reboot. Disconnecting, then
reconnecting a neighbor increments this counter.
Neighbor Entries Deleted Count: Shows the number of neighbor
deletions from the MIB for AgeOut Count and forced drops for
all ports. For example, if the admin status for port on a
neighbor device changes from tx_rx or txonly to disabled or
rxonly, then the neighbor device sends a "shutdown" packet out
the port and ceases transmitting LLDP frames out that port.
The device receiving the shutdown packet deletes all informa­
tion about the neighbor received on the applicable inbound port
and increments the counter .
Neighbor Entries Dropped Count: Shows the number of valid LLDP
neighbors the switch detected, but could not add. This can
occur, for example, when a new neighbor is detected when the
switch is already supporting the maximum number of neigh­
bors. Refer to "Neighbor Maximum" on page 14-51.
Neighbor Entries AgeOut Count: Shows the number of LLDP neigh­
bors dropped on all ports due to Time-to-Live expiring.
