Link Layer Discovery Protocol (LLDP)

Specified within the IEEE 802.1AB standard, the Link Layer Discovery Protocol (LLDP) is used by network devices in Ethernet segments and networks for advertising their identity, capabilities, and neighbors. The Link Layer Discovery Protocol may be used as a component in network management and monitoring applications, such as data center bridging. Providing a mechanism for endpoints to exchange configuration information, the implementation of LLDP is critical for preventing configuration mismatches.
