Configuring Protocol to CPU Queue Mapping
You can configure the mapping between CPU queues and the protocols that can be assigned to each CPU queue. This feature enables
you to optimize buffer usage and control the security related aspects corresponding to the control traffic.
To configure CPU bound control-plane traffic to map to specific CPU queues:
1. Create a CPU protocol group.
CONFIGURATION
cpu-protocol-group group-name
A CPU protocol group is created and the command mode changes to CPU-PROTOCOL-GROUP mode.
2. Create a protocol list.
CPU-PROTOCOL-GROUP
protocol-list protocol1, protocol2, protocol3,.....
The list of protocols that you specify using this command are associated with the protocol group that you created in Step1.
3. Exit the CPU PROTOCOL GROUP mode.
CPU-PROTOCOL-GROUP
exit
The command prompt enters the configuration mode.
4. Create a CoPP profile.
CONFIGURATION
copp-profile profile-name
The system enters the CoPP profile mode.
5. Assign a protocol group or a QoS policy to the CoPP profile that you have created.
COPP-PROFILE
cpu-queue queue-number {protocol-group group-name [qos-policy policy-name] | qos-policy
policy-name}
6. Enter Control Plane mode.
CONFIGURATION
control-plane-cpuqos
7. Apply the CoPP policy to the system.
CONTROL-PLANE-CPUQOS
copp-policy profile-name
The CoPP policy that you have specified is applied to the system.
Displaying CoPP Configuration
The CLI provides show commands to display the protocol traffic assigned to each control-plane queue and the current rate-limit applied to
each queue. Other show commands display statistical information for trouble shooting CoPP operation.
To view the rates for each queue, use the show cpu-queue rate cp command.
