New feature: CoPP software forwarding feature
Configuring CoPP
If the rate of packets sent to the control plane exceeds the processing capabilities of the control
plane (for example, when the device is suffering DoS attacks), the normal packets sent to the control
plane cannot be promptly processed, thus affecting the normal operation of protocols.
To protect the management interface against DoS attacks, which will cause service interruption, you
must perform traffic policing for the management interface.
CoPP allows you to perform traffic policing for the control plane or management interface control
plane. By default, the predefined QoS parameters are configured for packets of each protocol sent to
the control plane. Also, you can apply a user-defined QoS policy to the control plane to filter and
rate-limit the packets sent to the control plane. This makes sure the control plane can correctly
receive, transmit, and process packets.
