Suppose port G0/1's traffic type is dedicated. In this situation, you can:
Customize the inherited DoS settings for all of the traffic the interface monitors.
Create multiple DoS policies for multiple CIDR networks. You can create three unique DoS policies for 192.168.0.0/24, 192.168.1.0/24, and 192.168.2.0/24. Once these unique DoS instances have been created, the rest of the interface traffic is protected by the inherited DoS settings.
