Control Plane Policing Commands
This chapter is a reference for the Control Plane Policing (CoPP) commands.
clear interface cpu counters
Use this command to clear the CPU queue counters.
Command Syntax
clear interface cpu counters
Parameter
None
Command Mode
Exec mode and Privileged Exec mode
Applicability
This command was introduced before OcNOS version 1.3.
Example
OcNOS#clear interface cpu counters
cpu-queue
Use this command to set the protocol queue shaper and enable/disable queue monitoring for drop.
Note: Configuring the queue rate for guest is not available for Qumran2 devices. Configuring the queue rate for PTP is not allowed for Qumran1 and Qumran2 series platforms.

Command Mode
Exec mode and Privileged exec mode
Applicability
This command was introduced before OcNOS-SP version 2.4.
Example
Use the following command to configure rate/monitor/no-monitor for protocol queues:
OcNOS#configure terminal
OcNOS(config)#cpu-queue cpu-q0 rate 400
Use the following command to verify the rate received on each protocol queue:
OcNOS#show int cpu counters rate kbps
Load interval: 30 second
+-------------------+--------------+-------------+--------------+-------------+
| CPU Queue(%) | Rx kbps | Rx pps | Tx kbps | Tx pps |
+-------------------+--------------+-------------+--------------+-------------+
