Control Plane Policing (CoPP)
Control plane policing (CoPP) is supported on Dell Networking OS.
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.
