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 LLDP MED Port Settings page. An 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.
