Control Plane Policing (Copp); Clear Control-Traffic Protocol - Dell C9000 Series Reference 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. The CoPP filters prevent traffic that is not identified as legitimate
from reaching the control plane, and rate-limit traffic to an acceptable level.
On the switch, the control plane has 21 queues (0 to 20) divided into groups of seven queues for the Route
Processor, Control Processor, and line-card CPUs as follows:
• Queues 0 to 6 process packets destined to the Control Processor CPU .
• Queues 7 to 13 process packets destined to the Route Processor CPU.
• Queues 14 to 20 process packets destined to the line card CPU.
