Configuring Static Hierarchical Scheduling in a Dynamic Profile


You configure static scheduling and queuing in a dynamic profile for subscriber access. To configure CoS in a dynamic profile for subscriber access using static scheduling and queuing parameters:

  1. Configure the static CoS parameters in the [edit class-of-service] hierarchy.
    1. Enable the hierarchical scheduler for the interface.

      See Understanding Hierarchical CoS for Subscriber Interfaces.

    2. Configure the scheduler map and schedulers.

      When you configure static scheduling and queuing in a dynamic profile, you reference the scheduler map in the dynamic profile.

      See Configuring Schedulers.

    3. Configure the drop profiles.

      See Defining Packet Drop Behavior by Configuring RED Drop Profiles.

    4. Configure the forwarding classes.

      See Configuring a Custom Forwarding Class for Each Queue.

    5. Configure the rewrite-rules and classifier definitions.

      See Configuring Rewrite Rules and Configuring Behavior Aggregate Classifiers.

    See The Junos OS CoS Components Used to Manage Congestion and Control Service Levels for information about configuring the remaining CoS parameters.

  2. Configure a static or dynamic subscriber interface that can be referenced in the dynamic profile.
  3. Configure CoS parameters in a dynamic profile.
    1. Configure the dynamic profile.

      See Configuring a Basic Dynamic Profile.

    2. Configure traffic shaping and scheduling parameters in the dynamic profile using a traffic-control profile. Reference the scheduler map you configured in the static [edit class-of-service] hierarchy.

      See Configuring Static Traffic Shaping and Scheduling Parameters in a Dynamic Profile.

    3. Apply CoS parameters to a subscriber interface by referencing an interface in the dynamic profile.

      See Applying Traffic Shaping and Scheduling to a Subscriber Interface in a Dynamic Profile.

  4. To configure default values for subscribers on login, and enable subscribers to replace other CoS parameters when replacing services, configure variables in the dynamic profile.

    See Configuring Static Default Values for Traffic Scheduling and Shaping.
