摘要：
The disclosed apparatus includes a MAC learning table storing a MAC address and port identification information that uniquely identifies a port for transferring a frame to which the MAC address is assigned. The apparatus includes updating the MAC learning table, reading a MAC address of a link trace frame, transferring the link trace frame via a port determined based on the MAC learning table, storing a correspondence relationship of a predetermined MAC address and port identification information, saving a correspondence relationship set as an object to be deleted at a time of updating the MAC learning table, transferring the link trace frame, if there is no correspondence relationship relevant to the MAC address of the link trace frame in the MAC learning table, and sending a response frame to a switching hub which is an originator of the link trace frame with transfer of the link trace frame.
