SNMP (Simple Network Management Protocol) traps are a critical component in network monitoring and management. The primary purpose of SNMP traps is to send alerts or notifications to a management system based on predefined thresholds or events. When a specific condition occurs that meets the criteria set by the network administrator—such as a device experiencing high CPU usage, a link going down, or a threshold being exceeded—the device can generate an SNMP trap to inform the management system of the situation.

This functionality allows for real-time monitoring and prompt response to issues within the network without the need for constant polling of devices. It enhances the efficiency of network management by ensuring that important events are communicated instantly, enabling administrators to take necessary actions swiftly to maintain network performance and reliability.

Other options serve different purposes. Collecting TCP traffic data does not involve triggers but requires a continuous observation of traffic flows. Communicating configuration changes may utilize SNMP, but it typically involves different methods, such as SNMP set commands, rather than traps. Initiating data transfers is also outside the scope of SNMP traps, as they are not designed to manage data transfer processes but to alert administrators about specific events or conditions.
