Control Plane Policing (CoPP)

Control plane policing (CoPP) uses access control list (ACL) rules and quality of service (QoS) policies to create filters for a

system's control plane. That filter prevents traffic not specifically identified as legitimate from reaching the system control

plane, rate-limits, traffic to an acceptable level.

CoPP increases security on the system by protecting the routing processor from unnecessary or DoS traffic, giving priority to

important control plane and management traffic. CoPP uses a dedicated control plane configuration through the ACL and QoS

command line interfaces (CLIs) to provide filtering and rate-limiting capabilities for the control plane packets.
