The CLI configuration in this section uses a spoke-SDP defined in the context of a VPRN
interface. However the PW shaping feature is supported with all PW based services including the
PW template.
Provisioning Model
Operationally, the provisioning model in the case of the ingress PW shaping feature consists of the
following steps:
1. Create an ingress queue-group template and configure policers for each FC which needs
2. Apply the queue-group template to the network ingress context of all IOM3/IMM FPs
3. Configure FC-to-policer mappings together with the policer redirect to a queue-group in
The following are the constraints and rules of this provisioning model when used in the ingress
PW shaping feature:
1. Only a queue-group containing policers, can be instantiated in the network ingress
2. If the queue-group contains queues only, the instantiation in the data path is failed.
3. One or more instances of the same policer queue-group name and/or a different policer
4. The queue-group-name must be unique within all network ingress and access ingress

step which means the same network QoS policy can redirect different PWs to different
queue-group templates.
