LLDP is an open standard for network devices to communicate link-layer topology and connection endpoint information on IEEE 802 (Ethernet) LANs and MANs. LLDP is described in the IEEE standards document 802.1AB, Station and Media Access Control Connectivity Discovery. It allows a station on the network to advertise information about its capabilities, configuration, and identity to other LLDP-enabled stations on the same physical network. This information is stored in the device as a standard management information base (MIB) as specified in RFC 2922. A network management system can query these MIBs using SNMP to model the topology of the network.
