Another switch (20b) also transmits another LACP frame to the server (10). The LACP frame and the other LACP frame are for making request a for link aggregation to the server (10). A system identifier for the LACP frame is the same as the system identifier for the other LACP frame. A plurality of bypass ports (eth3, eth4) are provided. A faulty aggregation group identifier (OxOOBB) that is associated with a faulty port (ethO) and a port identifier (eth3) for a desig­ nated bypass port are associated in advance at a bypass port storage unit (212). Port identifiers for different designated bypass ports are associated with different faulty aggregation group identifiers.
