Description
The port on which LLDP frames are received or transmitted.
The number of LLDP frames transmitted on the port.
The number of LLDP frames received on the port.
The number of received LLDP frames containing some kind of error.
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.
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.
The number of well-formed TLVs, but with an unknown type value.
The number of organizationally TLVs received.
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.
