Parameter

Description

neighbors

The list of LLDP-compatible devices with LLDP advertisement enabled.

  • Chassis ID: the chassis ID

  • SysName: the name of the system

  • SysDescr: a description of the system containing information on the device's hardware and operating system

  • Management: the neighboring device address (contains IPv4 and IPv6 addresses and interface number for the specified management address)

  • Capability: the device's function (e.g., router, switch, etc.)

  • Port ID: the ID of the port from which the LLDPDU (Link Layer Discovery Protocol Data Unit) was transmitted

  • PortDescr: a description of the port

  • TTL: the TTL of the transmitted LLDP packets

statistics

The statistics on the interfaces for which a LLDP profile was specified:

  • Interface: the name of the Interface

  • Transmitted: the total LLDP frame count transmitted via the interface.

  • Received: the total LLDP frame count received on the interface.

  • Discarded: the number of LLDP frames received on this interface that were discarded.

  • Unrecognized: the number of LLDP frames with unconfirmed content received on this interface.

  • Ageout: each LLDP frame contains information on how long the LLDP information is valid (the ageout). If no new frames are accepted during the ageout period, the LLDP information is deleted.

  • Inserted: the number of added records containing information on LLDP neighbors.

  • Deleted: the number of deleted records containing information on LLDP neighbors.
Note To be able to view the information received via LLDP, the LLDP service must be activated on NGFW (LLDP profiles configured in the item library and activated in the interface settings).
