z Tx Frames :
The number of LLDP frames transmitted on the port.
z Rx Frames :
The number of LLDP frames received on the port.
z Rx Errors :
The number of received LLDP frames containing some kind of error.
z Frames 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's link is down, an LLDP shutdown frame is received, or when the
entry ages out.
z 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.
z TLVs Unrecognized :
The number of well-formed TLVs, but with an unknown type value.
z Org. Discarded :
The number of organizationally received TLVs.
z Age-Outs :
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.
z Auto-refresh :
To evoke the auto-refresh icon then the device will refresh the information automatically.
z Upper right icon (Refresh, Clear):
You can click them for refresh the LLDP Port Statistics information by manual. Or press
clear to clean up the entries.
