address from the addresses provided.

LLDP MED Network Policy
LLDP Media Endpoint Discovery (LLDP-MED) is an extension of LLDP that provides
the following additional capabilities to support media endpoint devices. Some of
the features of the LLDP Med Network Policy are:
• Enables the advertisement and discovery of network polices for real-time
applications such as voice and/or video.
• Device location discovery to allow creation of location databases and, in the
case of Voice over Internet Protocol (VoIP), Emergency Call Service (E-911)
by using IP Phone location information.
• Troubleshooting information. LLDP MED sends alerts to network managers
upon:
- Port speed and duplex mode conflicts
- QoS policy misconfigurations
