Abstract
A relay apparatus includes line cards, switch fabric cards, and a management card. The management card and the switch fabric cards are connected through a first communication network, and the switch fabric cards and the line cards are connected through a second communication network. The switch fabric card includes an error control unit. The error control unit stops switching of data transmission using a path of the second communication network by controlling the switch fabric card as an abnormal state based on an error signal that is output when a fault of the first communication network or an internal fault of the switch fabric card is detected as an error.
