LLDP Statistics
◆ Local Port – Port Identifier.
◆ Tx Frames – Number of LLDP PDUs transmitted.
◆ Rx Frames – Number of LLDP PDUs received.
◆ Rx Errors – The number of received LLDP frames containing some kind
of error.
◆ Frames Discarded – Number of frames discarded because they did
not conform to the general validation rules as well as any specific usage
rules defined for the particular Type Length Value (TLV).
◆ TLVs Discarded – Each LLDP frame can contain multiple pieces of
information, known as TLVs. 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 organizational TLVs discarded.
◆ Age-Outs – 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.
