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. The CoPP filters prevent traffic that is not identified as legitimate from reaching the control plane, and rate-limit traffic to
an acceptable level.
