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.
- Uses MQC (Modular QoS CLI)
- Control Plane Policing Architecture
- Prior to 12.4(4)T it was only possible to configure the aggregate interface
