Configuring Dynamic Scheduling and Queuing in a Dynamic Profile for Subscriber Access

You can configure dynamic scheduling and queuing in dynamic profile for subscriber access.

To configure dynamic scheduling and queuing for subscriber access:

1. Configure a static or dynamic subscriber interface.

   See Configuring Dynamic Subscriber Interfaces Using IP Demux Interfaces in Dynamic Profiles.

2. 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.

      See Configuring Traffic Shaping and Scheduling in a Dynamic Profile.

   3. Configure the schedulers and scheduler map in the dynamic profile.

      See Configuring Schedulers in a Dynamic Profile.

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

      See Applying CoS to an Interface in a Dynamic Profile.

3. (Optional) Configure variables in access and service profiles to enable RADIUS to activate subscriber and upgrade services through CoA.

   Because you have configured the scheduler map in the dynamic profile, queues are merged when subscribers change services. Other CoS parameters are replaced.

   When multiple subscribers are enabled on a DHCP subscriber interface, the system does not replace the parameters. Instead, it combines the values of the parameters to their maximum scalar value.

   1. Configure CoS variables in a dynamic profile.

      See Configuring CoS Variables in a Dynamic Profile

   2. (Optional) Enable multiple subscribers on a logical interface by configuring the aggregate-clients option for the dynamic profile attached to a DHCP subscriber interface.

      See Attaching Dynamic Profiles to DHCP Subscriber Interfaces.

4. Configure the remaining static CoS parameters in the [edit class-of-service] hierarchy.
   1. Configure the drop profiles. The scheduler map and schedulers are already configured in the dynamic profile.

      See the JUNOS Class of Service Configuration Guide for information about configuring the scheduler map.

   2. Enable the hierarchical scheduler for the interface.

   See the JUNOS Class of Service Configuration Guide for information about configuring the remaining CoS parameters.
