Egress pseudowire shaping

About this task

One or more spoke-sdps can have their FCs redirected to use policers in the same policer queue-group instance.

The egress PW shaping provisioning model allows the mapping of one or more PWs to the same instance of queues, or policers and queues, that are defined in the queue-group template.

Operationally, the provisioning model consists of the following steps:

Procedure

  1. Create an egress queue-group template and configure queues only, or policers and queues, for each FC that needs to be redirected.
  2. Apply the queue-group template to the network egress context of all ports where there exists a network IP interface that the PW packets can be forwarded on. This creates one instance of the template on the egress of the port. One or more instances of the same template can be created.
  3. Configure FC-to-policer or FC-to-queue mappings together with the redirect to a queue-group in the egress 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.
  4. Apply this network QoS policy to the egress context of a spoke-sdp inside a service, or to the egress context of a PW template and specify the redirect queue-group name.
    One or more spoke-sdps can have their FCs redirected to use queues only, or queues and policers, in the same queue-group instance.
