Local Counters
The displayed table contains a row for each port. The columns hold the following information:
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 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 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 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 :
The number of organizationally received TLVs.
Age-Outs :
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.
