LLDP Overview

LLDP allows the firewall to send and receive Ethernet frames containing LLDP data units (LLDPDUs) to and from neighbors. The receiving device stores the information in a MIB, which can be accessed by the Simple Network Management Protocol (SNMP). LLDP enables network devices to map their network topology and learn capabilities of the connected devices, which makes troubleshooting easier—especially for virtual wire deployments where the firewall would typically go undetected in a network topology.
