The displayed table contains a row for each port. The columns hold the following information:
Object Description
The port on which LLDP frames are received or transmitted.

Local Port
The number of LLDP frames transmitted on the port.

Tx Frames
The number of LLDP frames received on the port.

Rx Frames
The number of received LLDP frames containing some kind of error.

Rx Errors
If an 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 links down, an LLDP
shutdown frame is received, or when the entry ages out.

Frames 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 Discarded
The number of well-formed TLVs, but with an unknown type value.

TLVs Unrecognized
The number of organizationally TLVs received.

Org. Discarded
Each LLDP frame contains information about how long time the LLDP
information is valid (age-out time). If no new LLDP frame is received within the
age out time, the LLDP information is removed, and the
Age-Out
counter is
incremented.
