A scheduler policy can be applied to create egress schedulers used by SAP policers and queues. The schedulers comprising the policy are created at the time the scheduler policy is applied to the SAP. If any orphaned policers or queues exist on the egress SAP (when the specified scheduler name does not exist), and the policy application creates the required scheduler, the status on the policer or queue becomes non-orphaned.
Queues and policers are associated with the configured schedulers by specifying the parent scheduler defined within the policer queue definition from the SAP QoS policy. The scheduler is used to provide bandwidth to the queue relative to the operating constraints imposed by the scheduler hierarchy.
