The 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. [3] LLDP is used to advertise power over Ethernet capabilities and requirements ...

Label Distribution Protocol (LDP) is a protocol in which routers capable of Multiprotocol Label Switching (MPLS) exchange label mapping information. Two routers with an established session are called LDP peers and the exchange of information is bi-directional.
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 service discovery protocol (SDP) is a network protocol that helps accomplish service discovery. Service discovery requires a common language to allow software agents to make use of one another's services without the need for continuous user intervention.
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.
This layer is the protocol layer that transfers data between nodes on a network segment across the physical layer. [2] The data link layer provides the functional and procedural means to transfer data between network entities and may also provide the means to detect and possibly correct errors that can occur in the physical layer.
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 .
