25• In a QoS policy for control planes, if a system index classifier is configured, the associated trafficbehavior can contain only the car action or the combination of car and accounting packet actions.In addition, if the CAR action is configured, only its CIR setting can be applied.• In the QoS policy for a control plane, if a system index classifier is not configured, the associatedtraffic behaviors also take effect on the data traffic of the device where the control plane resides.Configuration procedureTo apply the QoS policy to the control plane:Step Command1.
