Figure 4-10-17: LLDP Port Statistics Page Screenshot
The page includes the following fields:
Object Description
• Port
The port on which LLDP frames are received or transmitted.
• TX Frame – Total
The number of LLDP frames transmitted on the port.
• RX Frame – Total
The number of LLDP frames received on the port.
• RX Frame – Discarded
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.
• RX Frame – Error
The number of received LLDP frames containing some kind of error.
• RX 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.
• RX TLVs –
Unrecognized
The number of well-formed TLVs, but with an unknown type value.
• RX Ageout - Total
The number of organizationally TLVs received.
