Dell S4048T User Manual

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.
