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 aggrega­ tion 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 faulty a port (ethO) is as­ sociated with a port identifier (eth3) for a selected bypass port. Port identifiers for different selected bypass ports are associated with dif­ ferent faulty aggregation group identifiers.
