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
Neighbours" 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 TLV
(Type Length Value). If a TLV is malformed, it will be counted and discarded.
TLVs
Unrecognized
The number of well-formed TLVs but with an unknown type value
Org. Discarded
