LLDP-MED is very similar to the Cisco Discovery Protocol (CDP). It has basic discovery capabilities that allow it to see information about devices that are connected to it. LLDP-MED allows the device to determine the capabilities that the connected device supports such as LAN speed, network policy, location identification, power, inventory, and trust extensions.
This document explains how to enable LLDP on the SPA525G and SPA525G2 IP Phones.
