A data transferring system, in which processes to match settings between devices mutually communicating are simplified, software for the processes is also simplified, and the amount of data to be processed is reduced, is disclosed. In a data transferring system of the PCI Express standard, when settings between facing ports of a switch and an end point are changed, a setting change is transmitted to the port of the end point being one of the facing ports by a configuration request. The port of the end point transmits the setting change to the port of the switch by a message request and the port of the switch executes the setting change. The port of the switch sends a completion message signifying the setting change completion to the port of the end point by a message request. The port of the end point executes the setting change.
