The following guidelines and caveats apply to the implementation of QoS policies.
Creating additional QoS policies is optional.
Default policies are created for service ingress, service egress, network, network-queue, and slope policies.
Associating a service with a QoS policy other than the default policy is optional.
A network queue, service egress, and service ingress QoS policy must consist of at least one queue. Queues define the forwarding class, CIR, and PIR associated with the queue.
