◆ Total Neighbors Entries Dropped – The number of times which the
remote database on this switch dropped an LLDPDU because the entry
table was full.

neighbor’s information has been deleted from the LLDP remote systems
MIB because the remote TTL timer has expired.
LLDP Statistics
◆ Local Port – Port Identifier.
◆ Tx Frames – Number of LLDP PDUs transmitted.
◆ Rx Frames – Number of LLDP PDUs received.
◆ Rx Errors – The number of received LLDP frames containing some kind
