LLDP-MED

LLDP-MED

The Link Layer Discovery Protocol-Media Endpoint Discovery or LLDP-MED is an enhancement to the Link Layer Discovery Protocol (LLDP) that is designed to allow for things such as:

* Auto-discovery of LAN policies (such as VLAN, Layer 2 Priority and Diffserv settings) leading to "plug and play" networking.
* Device location discovery to allow creation of location databases and, in the case of VoIP, E911 services.
* Extended and automated power management of Power over Ethernet endpoints.
* Inventory management, allowing network administrators to track their network devices, and determine their characteristics (manufacturer, software and hardware versions, serial / asset number).

The LLDP-MED protocol was formally approved and published as the standard ANSI/TIA-1057 by the Telecommunications Industry Association (TIA) in April 2006.
