Control Plane Policing

The Control Plane Policing feature allows users to configure a quality of service (QoS) filter that manages the traffic flow of control plane packets to protect the control plane of Cisco IOS routers and switches against reconnaissance and denial-of-service (DoS) attacks.
CoPP can help maintain packet forwarding and protocol states despite an attack or heavy traffic load on the router or switch.
