Local Counters
The displayed table contains a row for each port. The columns hold the following information:
Object Description
• 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
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.
• 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 TLVs received.
• 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.
