Chapter 3: Configuration
• Frames Discarded: If an LLDP frame is received on a port, and the switch’s internal table has run full, the LLDP frame is count-
ed 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 times 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: Check the auto-refresh box to set the unit to refresh information automatically.
• Icons, upper right of screen (Refresh, Clear): Click to refresh the LLDP Port Statistics information manually. Click Clear to
remove any current changes you have made.
