„ Local Counters
The displayed table contains a row for each port. The columns hold the following information:
Object Description
• Port The port on which LLDP frames are received or transmitted.
• Tx Frames The number of LLDP frames transmitted on the port.
• RX 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 links down, an LLDP
shutdown frame is received, or when the entry ages out.
• Rx Frame Errors The number of received LLDP frames containing some kind of error.
• Rx Frames Total The number of LLDP frames received on the port.
• Rx Frames 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.
• Rx Frames TLVs
Unrecognized
The number of well-formed TLVs, but with an unknown type value.
• Rx Frames Ageouts 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.
4.10.3 Local Information
Use the LLDP Local Information screen to display information about the Managed Switch, such as its MAC address, chassis
ID, system capabilities, system description, management IP address, and port information.
