Configuring and Applying IEEE 802.1ad Classifiers

 

If you apply an IEEE 802.1 classifier to a logical interface, this classifier takes precedence and is not compatible with any other classifier type. For Juniper Networks MX Series 5G Universal Routing Platform interfaces or IQ2 PICs with IEEE 802.1ad frame formats or EX Series switches, you can set the forwarding class and loss priority for traffic on the basis of the three IEEE 802.1p bits (three bits in either the inner virtual LAN (VLAN) tag or the outer VLAN tag) and the drop eligible indicator (DEI) bit. You can apply the default map or customize one or more of the default values.

You then apply the classifier to the interface on which you configure IEEE 802.1ad frame formats.

The following example requires you to navigate various levels in the configuration hierarchy. For instructions on how to do that, see Using the CLI Editor in Configuration Mode in the CLI User Guide.

  1. Define the custom IEEE 802.1ad map:
    1. Create the classifier by specifying a name for it and defining it as an IEEE-802.1ad (DEI) classifier.

    2. Assign the forwarding class and loss priority to the code-point alias.

  2. Apply the classifier to the logical interface:
    1. Specify the interface to which you want to apply the classifier.

    2. Specify the name of the classifier you want to apply to the interface.

  3. Verify the custom IEEE 802.1ad map configuration:
