<p>The present invention enables each switch apparatus to appropriately manage a correspondence relationship between a VLANID(s) and a port(s), without requiring manual setting or central management by a control apparatus. A switch apparatus includes: a plurality of ports; a VLAN setting management unit storing entries, in each of which VLAN information and at least one of the plurality of ports are associated with each other, and adding or updating, if an entry corresponding to a combination of VLAN information included in a packet received from a port and the reception port of the packet is not stored, a corresponding entry for the received packet; and a functional unit notifying a predetermined control apparatus of an added or updated content of the entry.</p> |
