Network IP Interface Forwarding Class-Based Redirection
Provisioning Model
This provisioning model allows the mapping of one ore more PWs to the same instance of queues,
or policers and queue, which are defined in the queue-group template.
Operationally, the provisioning model consists of the following steps:
1. Create an egress queue-group template and configure queues only or policers and queues
2. Apply the queue-group template to the network egress context of all IOM3/IMM ports
3. Configure FC-to-policer or FC-to-queue mappings together with the redirect to a queue-
The following are the constraints and rules of this provisioning model:
1. Queue-groups containing queues only or policers and queues can be instantiated in the
2. When a port is a LAG, one instance of the queue-group is instantiated on each member
3. One or more instances of the same queue-group name and/or a different queue-group
4. The queue-group-name must be unique within all network egress and access egress queue
5. A user attempt to instantiate the queue-group on the network egress context of a POS port
6. When a PW FC is redirected to use a queue or a policer and a queue in a queue-group and

This creates one instance of the template on the egress of the port. One or more instances
of the same template can be created.
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.
a. Apply this network QoS policy to the egress context of a spoke-sdp inside a

the queue-group name does not exist, the association is failed at the time the user
associates the egress context of a spoke-SDP to the named queue-group. In such a case,
the PW packet is fed directly to the corresponding egress queue for that FC used by the
