Recieve LLDP

Hi Sinichi_Kudo,

Depending on the role of the interface, LLDP reception is either enabled or disabled. In situations when multiple FortiSwitches connect to FortiGate using a FortiLink-enabled interface, it can be useful to have LLDP reception enabled to know which switch is connected to the physical FortiGate ports.

Device detection can scan LLDP as a source for device identification, but the FortiGate does not read or store the full information. Enabling LLDP reception allows the FortiGate to receive and store LLDP messages, learn about active neighbors, and makes the LLDP information available via the CLI, REST API, and SNMP.

Please refer to the documents below for more information:
