A basic service ingress QoS policy must conform to the following:
have a unique service ingress QoS policy ID
have a QoS policy scope of template or exclusive
have at least one default unicast FC queue
(optionally) use multipoint FC queue
(optionally) use unicast meter and BUM traffic
Configuring and applying QoS policies is optional. If no QoS policy is explicitly applied to a SAP, a default QoS policy is applied.
