Page 126 highlights

 Total Neighbours Entries Added : Shows the number of new entries added since switch reboot.  Total Neighbours Entries Deleted : Shows the number of new entries deleted since switch reboot.  Total Neighbours Entries Dropped : Shows the number of LLDP frames dropped due to the entry table being full.  Total Neighbours Entries Aged Out : Shows the number of entries deleted due to Time-To-Live expiring. 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 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.  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. 118

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 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.
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.
