Monitoring the QoS Scheduler Hierarchy
Purpose
Display information about the QoS scheduler hierarchy, including interfaces, resources, and shaping rates on a particular interface. Phantom nodes are not displayed in the output for this command.
If you do not specify the traffic-class-group keyword, the output displays information for the default traffic-class group.
Action
To display the scheduler hierarchy for a particular interface:

Individual shaping rate of a traffic resource in bits per second
Configured assured rate in bits per second or configured weight
