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.
