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:
• 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
Setting LLDP MED Network Policy
An LLDP-MED network policy is a related set of configuration settings for a specific real-
time application such as voice, or video. A network policy, if configured, can be included in
the outgoing LLDP packets to the attached LLDP media endpoint device. The media endpoint
device must send its traffic as specified in the network policy it receives. For example, a policy
can be created for VoIP traffic that instructs VoIP phone to:
• Send voice traffic on VLAN 10 as tagged packet and with 802.1p priority 5.
• Send voice traffic with DSCP 46.
Network policies are associated with ports by using the
administrator can manually configure one or more network policies and the interfaces where
the policies are to be sent. It is the administrator's responsibility to manually create the VLANs
and their port memberships according to the network policies and their associated interfaces.
In addition, an administrator can instruct the device to automatically generate and advertise a
network policy for voice application based on the voice VLAN maintained by the device.
Refer the Auto Voice VLAN section for details on how the device maintains its voice VLAN.
To define an LLDP MED network policy:
Click Administration > Discovery - LLDP > LLDP MED Network Policy.
This page contains previously-created network policies.
Select Auto for LLDP-MED Network Policy for Voice Application if the device is to
automatically generate and advertise a network policy for voice application based on the voice
VLAN maintained by the device.
