You can use this by Configuring Control Plane Policing (CoPP).
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 is disabled by default.
CoPP is only supported on ingress (service-policy output CoPP cannot be applied to the control plane interface). Neither egress CoPP nor silent mode is supported.
Just follow the CoPP Configuration Guidelines and Restrictions .
CoPP uses MQC to define traffic classification criteria and to specify the configurable policy actions for the classified traffic. You must first identify the traffic to be classified by defining a class map. The class map defines packets for a particular traffic class. After you have classified the traffic, you can create policy maps to enforce policy actions for the identified traffic. The control-plane global configuration command allows the CoPP service policies to be directly attached to the control plane.
Use the below mentioned URL for Defining Traffic Classification
To enter control-plane configuration mode, which allows users to associate or modify attributes or parameters (such as a service policy) that are associated with the control plane of the device, use the control-plane command in global configuration mode. To remove an existing control-plane configuration from the router, use the no form of this command.
