The purpose of the present invention is to improve a function of changing tunnel setting information for a switch that functions as a tunnel endpoint of an overlay network system. In the present invention, a switch that functions as a tunnel endpoint of an overlay network system is equipped with: a tunnel processing unit that performs capsulization and decapsulization of frames sent to and received from the opposing tunnel endpoint; and a command processing unit that, upon receiving an instruction to change flow identification information for identifying a capsulized frame, instructs the tunnel processing unit to receive the frame with flow identification information for before and after the change, and thereafter instructs the tunnel processing unit to change the flow identification information to be set in a frame being sent. |
