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:
host1# show qos scheduler-hierarchy interface fastEthernet 9/0
Scheduler hierarchy for the default traffic-class group

To display the QoS scheduler hierarchy using a filter as an alternative to using the level keyword:
