Figure 12: Scheduler Policy on Customer Site and Scheduler Hierarchy Creation

Queues become associated with schedulers when the parent scheduler name is defined within

the queue definition in the SAP ingress policy. The scheduler is used to provide bandwidth

to the queue relative to the operating constraints imposed by the scheduler hierarchy.

Scheduler Policies Applied to SAPs

A scheduler policy can be applied to create egress schedulers used by SAP queues. The

schedulers comprising the policy are created at the time the scheduler policy is applied to the

SAP. If any orphaned queues exist (queues specifying a scheduler name that does not exist)

on the egress SAP and the policy application creates the required scheduler, the status on the

queue will become non-orphaned.

Queues are associated with the configured schedulers by specifying the parent scheduler

defined within the queue definition from the SAP egress policy. The scheduler is used to

provide bandwidth to the queue relative to the operating constraints imposed by the scheduler
