Quality of Service in a Policy Rules Context
QoS can be specified directly in a policy role as stated in Assigning a Class of Service to Policy Role. A CoS can also be applied to a policy rule. The CoS specified at the policy role level is the default and is only used if no rule is triggered. Therefore, if a CoS is applied to both the policy role and a policy rule, the CoS specified in the policy rule takes precedence over the CoS in the policy role for the traffic classification context specified in the policy rule. As stated in the policy role discussion, CoS configuration details are beyond the scope of this document.
