What is the correct configuration order when enabling CoPP?

The correct configuration order for enabling Control Plane Policing (CoPP) is to start with the Access Control List (ACL), followed by the class map, then the policy map, and finally the service policy.

Beginning with the ACL is essential because it defines the traffic criteria that will be used to categorize packets. The class map then uses the settings from the ACL to classify the traffic into predefined classes. After the traffic is classified, the policy map can apply specific actions to the classified traffic, such as policing or shaping. Finally, the service policy binds the policy map to the control plane, allowing the defined actions to take effect. This order ensures that each step builds upon the last, leading to a coherent application of policies to manage and protect the control plane effectively.

Establishing this sequence not only follows Cisco guidelines but also clarifies each role in the CoPP configuration process. Understanding this order is crucial for network engineers who need to implement effective rate limiting and security measures for their network devices.
