Configure the QoS profile.
3.
host1(config)#qos-profile vcSharedShaping
Create group nodes.
4.
host1(config-qos-profile)#atm group AF scheduler-profile default
host1(config-qos-profile)#atm group EF scheduler-profile default
Create VC nodes for each group and for traffic in the default group.
5.
host1(config-qos-profile)#atm-vc node
host1(config-qos-profile)#atm-vc node group AF
host1(config-qos-profile)#atm-vc node group EF
Create queues for the best-effort, video, and voice traffic. Apply the scheduler profile
6.
that defines the shared-shaping rate to the best-effort queue. Apply the legacy shaper
profiles to the voice and video traffic queues.
host1(config-qos-profile)#atm-vc queue traffic-class best-effort scheduler-profile
shared-1mbps
host1(config-qos-profile)#atm-vc queue traffic-class video scheduler-profile 300Kbps
host1(config-qos-profile)#atm-vc queue traffic-class voice scheduler-profile 200Kbps
host1(config-qos-profile)#exit
Attach the QoS profile to an ATM subinterface.
7.
host1(config)#interface atm 11/0.1
host1(config-interface)#qos-profile vcSharedShaping
host1(config-interface)#exit
In this example, the constituents of the VC shared shaper are the VC 1 best effort node,
the VC 1 Group EF node, and the VC 1 Group AF node. The available bandwidth is strictly
allocated in the following order:
VC 1 EF group node
1.
VC 1 AF group node
2.
VC 1 best effort node
