Abstract
A chassis type switch is provided which can shorten a time required for switching-over to a backup route when a failure has occurred in a line card. In a chassis type switch including a plurality of line cards within a chassis, the switch further includes a failure detection unit for detecting a failure in each of the plural line cards, and a forced flooding processing unit included in each of the plural line cards and operating such that when, in trying to transfer a received unicast frame to another line card, a failure is detected in the relevant line card at a transfer destination, the received unicast frame is forcibly transferred to all ports of the own line card other than a reception port thereof and to all other line cards.
