3 Apply Multiple Services on an Interface—In this procedure, the classification and queuing policies are
applied on the interface.
/*Applying Policies on an Interface*/
Interface TenGigE0/0/0/3/0
service-policy output classification-policy
service-policy output queue-parent
To summarize, two policies (classification and queuing policies) are applied in the Egress direction. The
classification policy executes first and classifies traffic at different precedence levels and marks the traffic-class
field. The queuing policy executes second, matches on the traffic-class field to select the queue. For traffic
matching in different classification precedence to share the same queue, mark the traffic-class field with the
same value.
Verification
The show qos interface interface-name output command displays:
• per class per output policy QoS configuration values
• queuing policy followed by the classification policy
• traffic-classes matched by each class in queuing-policy
