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
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.
