Why Is the CPU Usage Degraded After the Interface Information Access Method Used by the NMS Is Changed?

Why Is the CPU Usage Degraded After the Interface Information Access Method Used by the NMS Is Changed?

The NMS can use either the get-next or get mode to access interface information. In the get-next mode, a switch receives a request for interface information from the NMS, obtains the interface information from the buffer, and then reports the information to the NMS. In the get mode, a switch receives a request for interface information from the NMS, collects information about the specified interface in real time, and then report the information to the NMS. If the NMS needs to frequently access interface information or access a huge bulk of information, the get mode will cause a high CPU usage because the switch collects information in real time. Therefore, the get-next mode is recommended.
