Control Plane Policing

The Control Plane Policing feature allows you to configure a quality of service (QoS) filter that manages

the traffic flow of control plane packets to protect the control plane of routers and switches against

reconnaissance and denial-of-service (DoS) attacks. In this way, the control plane (CP) can help maintain

packet forwarding and protocol states despite an attack or heavy traffic load on the router or switch.

Control Plane Policing is only supported on the RSP2 module.
