LLDP Media Endpoint Discovery (LLDP-MED) increases network flexibility
by enabling various IP systems to co-exist on a single network, and provides
the following features:
• Detailed network topology information, including information on which
devices are located on the network and where the devices are located, for
example, which IP phone is connect to which port, which software is
running on which switch, and which port is connected to which device.
• Automatic deployment of policies over networks for:
–QoS Policies
–Voice VLANs
• Emergency Call Service (E-911) via IP phone location information.
• Troubleshooting information. LLDP MED sends network managers alerts
for:
– Port speed and duplex mode conflicts
– QoS policy misconfigurations
