LOCAL COUNTERS
The displayed table contains a row for each interface. The columns hold the following
information:
Local Interface
The interface on which LLDP frames are received or transmitted.
Tx Frames
The number of LLDP frames transmitted on the interface.
Rx Frames
The number of LLDP frames received on the interface.
Rx Errors
The number of received LLDP frames containing some kind of error.
Frames Discarded
If a LLDP frame is received on a interface, 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 interface'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.
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.
Clear
If checked the counters for the specific interface are cleared when
