Globally Applying the QoS policy globally —
Generally, the action of redirecting traffic to the CPU and the action of redirecting traffic to an

You can use the display traffic behavior command to view the traffic redirecting configuration.
A QoS policy that contains a traffic redirecting action can be applied only to the incoming traffic.
