diagnose lldprx neighbor
Use this command to view LLDP neighbor information received on the FortiADC device. It displays details about the directly connected devices discovered via the Link Layer Discovery Protocol (LLDP) on the device’s interfaces. This information can help network administrators verify connectivity, troubleshoot physical link issues, and maintain an accurate view of the network topology.
