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

host1#show qos scheduler-hierarchy interface fastEthernet 9/0 full | include subscriber-best-effort
vlan Eth9/0.1 subscriber-best-effort 2000000 default vlan Eth9/0.2 subscriber-best-effort 6000000 default vlan Eth9/0.3 subscriber-best-effort 8000000 default
To display the QoS scheduler hierarchy using a filter as an alternative to using the level keyword:
host1#show qos scheduler-hierarchy interface fastEthernet 9/0 full | include level 2 vlan Eth9/0.1 vlan node level 2 vlan Eth9/0.2 vlan node level 2 vlan Eth9/0.3 vlan node level 2 svlan Eth9/0 svlan 2 svlan node EF level 2
