The '''Link Layer Discovery Protocol''' ('''LLDP''') is a vendor-neutral [[link layer]] protocol used by [[network device]]s for advertising their identity, capabilities, and neighbors on a [[local area network]] based on [[IEEE 802]] technology, principally [[wired Ethernet]].<ref>{{cite web

==Applications==
The Link Layer Discovery Protocol may be used as a component in [[network management]] and [[network monitoring]] applications.
One such example is its use in [[data center bridging]] requirements. The '''{{visible anchor|Data Center Bridging Capabilities Exchange Protocol}}''' (DCBX) is a discovery and capability exchange protocol that is used for conveying capabilities and configuration of the above features between neighbors to ensure consistent configuration across the network.<ref>{{cite web

* Auto-discovery of LAN policies (such as VLAN, [[802.1q|Layer 2 Priority]] and [[Differentiated services]] (Diffserv) settings) enabling [[plug and play]] networking.
* Device ___location discovery to allow creation of ___location databases and, in the case of [[Voice over Internet Protocol]] (VoIP), [[Enhanced 911]] services.
* Extended and automated power management of [[Power over Ethernet]] (PoE)
* Inventory management, allowing network administrators to track their network devices, and determine their characteristics (manufacturer, software and hardware versions, serial or asset number).
