Control Plane Policing (CoPP)
Control plane policing (CoPP) uses access control list (ACL) rules and quality of service (QoS) policies to create lters for a system’s
control plane. That lter prevents trac not specically identied as legitimate from reaching the system control plane, rate-limits,
trac to an acceptable level.
CoPP increases security on the system by protecting the routing processor from unnecessary or DoS trac, giving priority to
important control plane and management trac. CoPP uses a dedicated control plane conguration through the ACL and QoS
command line interfaces (CLIs) to provide ltering and rate-limiting capabilities for the control plane packets.
The following illustration shows an example of the dierence between having CoPP implemented and not having CoPP implemented.
