How does Control Plane Policing protect the route processor?
| A. |
It disables access to the control plane during an attack. | |
| B. |
It dynamically enables ingress ACLs on selected interfaces. | |
| C. |
It marks non-essential traffic and moves it to the Scavenger class. | |
| D. |
It treats the route processor as a separate entity within MQC. |
The control plane policing (CoPP) feature increases security on the switch by protecting the RP from unnecessary or DoS traffic and giving priority to important control plane and management traffic. You can use CoPP to protect the control and management planes, and ensure routing stability, reachability, and packet delivery. CoPP uses a dedicated control plane configuration through the modular QoS CLI (MQC) to provide filtering and rate-limiting capabilities for the control plane packets. CoPP uses MQC to define traffic classification criteria and to specify the configurable policy actions for the classified traffic.
