Local Counters
The displayed table contains a row for each port. The columns hold the following information:
Local Port :

The port on which LLDP frames are received or transmitted.
Tx Frames :

The number of LLDP frames transmitted on the port.
Rx Frames :

The number of LLDP frames received on the port.
Rx Errors :

The number of received LLDP frames containing some kind of error.
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 Neighbours" 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. Discarded :

The number of organizationally received TLVs.
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.
Auto-refresh :

To evoke the auto-refresh icon then the device will refresh the information automatically.
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.
