This page provides an overview of all LLDP traffic.
Two types of counters are shown. Global counters are counters that refer to the whole switch,
while local counters refer to per interface counters for the currently selected switch.

Description
Global Counters
Neighbor entries were last change Shows the time when the last entry was last deleted or added. It also shows the
time elapsed since the last change was detected.
Total Neighbors Entries Added
Shows the number of new entries added since switch reboot.
Total Neighbors Entries Deleted
Shows the number of new entries deleted since switch reboot.
Total Neighbors Entries Dropped
Shows the number of LLDP frames dropped due to the entry table being full.
Total Neighbors Entries Aged Out Shows the number of entries deleted due to Time-To-Live expiring.
Local Counters
Local Port
The port on which LLDP frames are received or transmitted.
Tx Frames
The number of LLDP frames transmitted on the port.
Rx Frames
The number of LLDP frames received on the port.
Rx Errors
The number of received LLDP frames containing some kind of error.
Frames Discarded
If a LLDP frame is received on a port, and the switch’s internal table has run full,
the LLDP frame is counted and discarded. This situation is known as “Too Many
Neighbors” in the LLDP standard. LLDP frames require a new entry in the table
when the Chassis ID or Remote Port ID is not already contained within the table.
Entries are removed from the table when a given port’s link is down, an LLDP
shutdown frame is received, or when the entry ages out.
TLVs Discarded
Each LLDP frame can contain multiple pieces of information, known as TLVs
(TLV is short for “Type Length Value”). If a TLV is malformed, it is counted and
discarded.
TLVs Unrecognized
The number of well-formed TLVs, but with an unknown type value.
Org. Discarded
If LLDP frame is received with an organizationally TLV, but the TLV is not
supported the TLV is discarded and counted.
