LLDP MED Network Policy

The 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. 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.

To define an LLDP MED network policy, follow these steps:

Procedure

Step 1

Click Administration > Discovery LLDP > LLDP MED Network Policy.

This page contains previously-created network policies.

Step 2

Check Enable next to the LLDP MED Network Policy for Voice Application option to automatically generate and advertise a network policy for voice application based on the voice VLAN maintained by the device.

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.

  • Application—Select the type of application (type of traffic) for which the network policy is being defined.

  • VLAN ID—Enter the VLAN ID to which the traffic must be sent.

  • VLAN Tag—Select whether the traffic is Tagged or Untagged.

  • User Priority—Select the traffic priority applied to traffic defined by this network policy. This is the CoS value.

  • DSCP Value—Select the DSCP value to associate with application data sent by neighbors. This value informs them how they must mark the application traffic they send to the device.

Step 6

Click Apply. The network policy is defined.

Note

You must manually configure the interfaces to include the desired manually-defined network policies for the outgoing LLDP packets using the LLDP MED Port Settings.
