    Link Layer Discovery Protocol (LLDP) is a layer-2 Ethernet protocol for managing devices. LLDP allows an exchange of information between PSE and a PD. This information is formatted in type–length–value (TLV) format. PoE standards define TLV structures used by PSE and PDs to signal and negotiate available power.
