The Link Layer Discovery Protocol (LLDP) is a vendor-neutral link layer protocol used by network devices for advertising their identity, capabilities, and neighbors on a local area network based on IEEE 802 technology, principally wired Ethernet. [1]
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.

A 2006 fall update for the Xbox 360 enabled support for the LLTD protocol. [5] Being a link layer (or OSI Layer 2) implementation, LLTD operates strictly on a given local network segment. It cannot discover devices across routers, an operation which would require Internet Protocol level routing.
To signal the capability for frame pre-emption on a link, an Ethernet switch announces this capability through the LLDP (Link Layer Discovery Protocol). When a device receives such an LLDP announcement on a network port and supports frame pre-emption itself, it may activate the capability.
PCM uses Link Layer Discovery Protocol (LLDP, Cisco Discovery Protocol (CDP) and FDP (Foundry) for detecting network devices; For identification and deep inspection of network devices SNMP V2c or V3 is used. Network traffic is analysed using RMON and sFlow.
Cisco Discovery Protocol (CDP) is a proprietary data link layer protocol developed by Cisco Systems in 1994 [1] by Keith McCloghrie and Dino Farinacci. It is used to share information about other directly connected Cisco equipment, such as the operating system version and IP address .
