SAP-based redirection

About this task

Redirecting a SAP forwarding class to a queue within an egress port-based or ingress forwarding plane queue group using SAP-based redirection requires four steps.

Procedure

  1. Create an ingress or egress queue group template. If the forwarding class redirection is in the ingress SAP path, an ingress queue group template must be created. Similarly, an egress queue group template must be created for egress forwarding class redirection. Optionally, the queues in a template can be created using default parameters. Individual queues must be created before they are associated with a forwarding class. The default queue parameters may be overridden on each port-based queue group.
  2. (This step and the following step can be done in the opposite order.) Create an ingress queue group instance on the forwarding plane of the IOM/IMM/XMA, or an egress port queue group with the same name as the template on the port associated with the SAP.
    On ingress:
    config>card>fp>ingress>access>queue-group queue-group-name instance instance-id [create]
    On egress:
    config>port>ethernet>access>egress>queue-group queue-group-name [instance instance-id]
  3. Redirect the SAP ingress forwarding class policer in the SAP-ingress QoS policy using the keyword fp-redirect-group keyword on the policer, or SAP egress forwarding class queue or policer using the port-redirect-group keyword. (Steps 2 and 3 may be done in opposite order.)
    On ingress:
    config>qos>sap-ingress policy-id
    fc fc-name
    queue queue-id fp-redirect-group
    On egress:
    config>qos>sap-egress policy-id
    fc fc-name
    queue queue-id port-redirect-group-queue
    config>qos>sap-egress policy-id
    fc fc-name
    policer policer-id port-redirect-group-queue
  4. Finally, the SAP ingress or SAP egress QoS policy must be applied to the SAP. The named queue group instance that was created on the ingress forwarding plane or the egress port must be specified at this time.
    On ingress:
    config>service>epipe>sap sap-id
    ingress
    qos sap-ingress-policy-id fp-redirect-group queue-group-name instance instance-id
    On egress:
    config>service>epipe>sap sap-id
    egress
    qos sap-egress-policy-id port-redirect-group queue-group-name instance instance-id
