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.
To define an LLDP MED network policy:
STEP 1 Click Administration > Discovery - LLDP > LLDP MED Network Policy.
This page contains previously-created network policies.
STEP 2 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.
NOTE When this box is checked, you may not manually configure a voice
network policy.
STEP 3 Click Apply to add this setting to the Running Configuration file.
STEP 4 To define a new policy, click Add.
STEP 5 Enter the values:
• Network Policy Number—Select the number of the policy to be created.
