The Link Layer Discovery Protocol-Media Endpoint Discovery (LLDP-MED) is an enhancement to LLDP (Link Layer Discovery Protocol) that features:

• Auto-discovery of LAN policies (such as VLAN, Layer 2 Priority and DiffServ settings), enabling plug and play networking.
• Device location discovery for creation of location databases.
• Extended and automated power management of Power over Ethernet endpoints.
• Inventory management, enabling network administrators to track their network devices and determine their characteristics (manufacturer, software and hardware versions, serial/asset number).
