LLDP-MED: VoIP integration

This feature integrates Link Layer Discovery Protocol-Media Endpoint Discovery (LLDP-MED) with voice over IP (VoIP). Supported platforms use Link Layer Discovery Protocol (LLDP) and LLDP-MED to learn and distribute device information on network links. The information allows the supported platforms to quickly identify a variety of devices, resulting in a LAN that interoperates smoothly and efficiently.
