5.3.4 MONITORING — LLDP STATISTICS
FIGURE 5-21. LLDP STATISTICS SCREEN
Tx Frames: The number of LLDP frames transmitted on the port.
Rx Frames: The number of LLDP frames received on the port.
Rx Error: The number of received LLDP frames containing some kind of error.
Discarded Frames: 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’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. TLVs Discarded: The number of organizationally received TLVs.
Ageouts: Each LLDP frame contains information about how long 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.
