Configuring the Three-Parameter Scheduler
When configuring the Three-Parameter Scheduler, consider the following guidelines:
• To use the three-parameter scheduler, a queueing class must be enabled. To enable a queueing class,
• If you configure only one parameter, the scheduler uses default values for the other two parameters.
• You can configure all 3 parameters in the same class.
• Minimum bandwidth must be less than maximum bandwidth.
you must configure at least one of the three parameters. When at least one parameter is configured, a
queue is assigned to the class.
