There is provided port switches SWP1 to SWP4, fabric switches SWF1 and SWF2, and user switches SWU1 and SWU2, the port switches SWP1, SWP2 functioning logically as one switch by being connected with a shared communication line between redundancy ports Pr. The port switch SWP2 may receive frames from the user switch SWU1, and when the frames are to be originally transferred from a port P1 to the fabric switch SWF1, the frames are transferred though the redundancy port Pr to the port switch SWP1 if there is a fault on the port P1 side. The port switch SWP1 transfers the frames received from the port switch SWP2 through the redundancy port Pr to the fabric switch SWF1 that is the original transfer destination. |
