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 Z9500 switch, the control plane has 24 queues (0 to 23) divided into groups of eight queues for
the Route Processor, Control Processor, and line-card CPUs as follows:
• Queues 0 to 7 process packets destined to the Control Processor CPU .
• Queues 8 to 15 process packets destined to the Route Processor CPU.
• Queues 16 to 23 process packets destined to the line card CPU.
clear control-traffic protocol
Clear all per-protocol counters of rate-limited control-plane traffic.
Z9500
Syntax
clear contol—traffic protocol [cp-switch | linecard slot-id
portset port-pipe] counters
Parameters
cp-switch Enter the keyword cp-switch to display counters for rate-
limited traffic on the central switch (aggregated CoPP).
linecard slot-id
portset port-
pipe
Enter the slot ID and port pipe to display counters for rate-
limited traffic on a specified Z9500 line card and port set.
The range of Z9500 slot IDs is from 0 to 2. The range of
port-pipe numbers is: 0 to 2 on line card 0; 0 to 3 on line
cards 1 and 2.
Defaults Clear per-protocol rate-limiting counters for all control-plane and port-set (port-
pipe) traffic.
