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 '''''' (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. LLDP is used to advertise
power over Ethernet capabilities and requirements and negotiate power delivery.
Media endpoint discovery extension Media Endpoint Discovery is an enhancement of LLDP, known as
LLDP-MED, that provides the following facilities: • Auto-discovery of LAN policies (such as VLAN,
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) end points. • Inventory management, allowing network administrators to track their network devices, and determine their characteristics (manufacturer, software and hardware versions, serial or asset number). The LLDP-MED protocol extension was formally approved and published as the standard ANSI/TIA-1057 by the
Telecommunications Industry Association (TIA) in April 2006. == System Capability Codes ==
