Configuring and applying QoS policies is optional. If no QoS policy is explicitly applied to a SAP or IP interface, a default QoS policy is applied.
To create a scheduler policy, define the following:
Define a scheduler policy ID value. The system does not dynamically assign a value.
Include a description. The description provides a brief overview of policy features.
Specify the tier level. A tier identifies the level of hierarchy that a group of schedulers are associated with.
Specify a scheduler name. A scheduler defines bandwidth controls that limit each child (other schedulers and queues) associated with the scheduler.
Specify a parent scheduler name to be associated with a level 1, 2, or 3 tier.
Optionally, modify the bandwidth that the scheduler can offer its child queues or schedulers. Otherwise, the scheduler is allowed to consume bandwidth without a scheduler-defined limit.
The following displays a scheduler policy configuration:
