Abstract: In a monitoring control system that employs a simple network management protocol, an operations system sends Set Request including a block request to a device to be operated when a specific hardware in the device is to set to a block status. A controller in the device that receives the block request starts a block processing to the designated specific hardware, changes a status of an item in a management information base related to the block of the hardware to a block status, sends back Get Response including a change result to the operations system. The controller then generates Trap including a request ID that indicates the block request, and sends the Trap to the operations system when completing the block processing.
