Per-Port LLDP Counters:
NumFramesRecvd: Shows the total number of valid, inbound
LLDP advertisements received from any neighbor(s) on < port-
list >. Where multiple neighbors are connected to a port through
a hub, this value is the total number of LLDP advertisements
received from all sources.
NumFramesSent: Shows the total number of LLDP advertise­
ments sent from < port-list >.
NumFramesDiscarded: Shows the total number of inbound LLDP
advertisements discarded by < port-list >. This can occur, for
example, when a new neighbor is detected on the port, but the
switch is already supporting the maximum number of neigh­
bors. Refer to "Neighbor Maximum" on page 14-51. This can
also be an indication of advertisement formatting problems in
the neighbor device.
Frames Invalid: Shows the total number of invalid LLDP adver­
tisements received on the port. An invalid advertisement can
be caused by header formatting problems in the neighbor
device.
TLVs Unrecognized: Shows the total number of LLDP TLVs
received on a port with a type value in the reserved range. This
could be caused by a basic management TLV from a later LLDP
version than the one currently running on the switch.
TLVs Discarded: Shows the total number of LLDP TLVs discarded
for any reason. In this case, the advertisement carrying the
TLV may be accepted, but the individual TLV was not usable.
Neighbor Ageouts: Shows the number of LLDP neighbors
dropped on the port due to Time-to-Live expiring.
