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
                                                                  assured
                                                          shared   rate

To display a summary of the scheduler profiles stacked above the specified interface:

host1#show qos scheduler-hierarchy interface fastEthernet 9/0 summary
 Total number of nodes:  7
    Level 0 nodes:       1

    Level 1 queues:      1
    Level 2 queues:      0
    Level 3 queues:      7

To display information about a specified interface in condensed format:

host1#show qos scheduler-hierarchy interface fastEthernet 9/0 brief

To display the scheduler level, scheduler profile that controls QoS behavior of the scheduler nodes and queues, and the burst associated with shaping rates:

host1#show qos scheduler-hierarchy interface fastEthernet 9/0 full | include 
subscriber-best-effort
vlan Eth9/0.1        subscriber-best-effort                 2000000 default

vlan Eth9/0.3        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

svlan Eth9/0 svlan 2     svlan node EF                 level 2
