In the case that a target MAC(Media Access Control) address exists in a cache by source learning, the ethernet switch(101) transmits the ethernet frame to the corresponding port. Otherwise, the ethernet switch(101) executes broadcasting. In the state that a main CPU(102) sets up a physical interface(401) in a promiscuous mode, the ether-type of the ethernet frame received through the ethernet switch(101) is examined to confirm whether the ethernet frame is a data packet inputted for the main CPU(102) as a destination. If so, it is judged that to which virtual interface the data packet is to be transmitted by using the added slot and port information, and the data packet is transmitted to the corresponding interface.
