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
