Ingress pseudowire shaping

About this task

The ingress PW rate-limiting feature uses a policer in the queue-group provisioning model. This model allows the mapping of one or more PWs to the same instance of policers that are defined in a queue-group template.

Operationally, the provisioning model in the case of the ingress PW shaping feature consists of the following steps:

Procedure

Create an ingress queue-group template and configure policers for each FC that needs to be redirected and optionally, for each traffic type (unicast, broadcast, unknown, or multicast).
Apply the queue-group template to the network ingress forwarding plane where there exists a network IP interface that the PW packets can be received on. This creates one instance of the template on the ingress of the FP. One or more instances of the same template can be created.
Configure FC-to-policer mappings together with the policer redirect to a queue-group in the ingress context of a network QoS policy. No queue-group name is specified in this step, which means the same network QoS policy can redirect different PWs to different queue-group templates.
Apply this network QoS policy to the ingress context of a spoke-sdp inside a service, or to the ingress context of a PW template and specify the redirect queue-group name.
