Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a switching hub in which loss of a frame does not occur at the time of failure restoration and manual switching of a port.SOLUTION: A switching hub 1 includes a plurality of line cards 2. The line card 2 incudes a FDB 315 that associates a MAC address with a port ID or a LAG ID and stores the associated address and ID, a LAG distribution table 332 that associates the LAG ID and a distribution ID with the port ID and stores the associated IDs, a first distribution table 330 that associates the distribution ID with the port ID and stores the associated IDs, and a second distribution table 335 that associates the distribution ID with the port ID and stores the associated IDs so that the correspondence relationship is different from that of the first distribution table.
