QoS Scheduler Policies
Quality of Service Guide 537
A basic QoS port scheduler policy must conform to the following:
• Each QoS port scheduler policy must have a unique policy name.
Create a QoS Scheduler Policy
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:
• A scheduler policy ID value. The system will 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 2 or 3 tier.
• You can modify the bandwidth that the scheduler can offer its child queues or
schedulers. Otherwise, the scheduler will be allowed to consume bandwidth without
a scheduler-defined limit.
The following displays a scheduler policy configuration:
