profile containing the shared-shaping rate is applied to the VP node that is in the
default group and contains the best-effort queue.
host1(config-qos-profile)#atm-vp node scheduler-profile shared-5Mbps
host1(config-qos-profile)#atm-vp node group AF scheduler-profile 2Mbps
host1(config-qos-profile)#atm-vp node group EF scheduler-profile 400Kbps
Create a VC node for the default group.
8.
host1(config-qos-profile)#atm-vc node
Create queues for the best-effort, video, and voice traffic.

host1(config-qos-profile)#atm-vc queue traffic-class best-effort
host1(config-qos-profile)#atm-vc queue traffic-class AF
host1(config-qos-profile)#atm-vc queue traffic-class EF
host1(config-qos-profile)#exit
Attach the QoS profile to an ATM subinterface.
10.
host1(config)#interface atm 11/0.1
host1(config-interface)#qos-profile vpSharedShaping
In this example, the constituents of the VP shared shaper are the VP 1 default group node,
the VP 1 Group EF node, and the VP 1 Group AF node. The available bandwidth is strictly
allocated in the following order:
VP1 EF group node
1.
VP1 AF group node
2.
VP1 default group node
