Abstract
An automatic VLAN configuration information setting system comprising an automatic VLAN configuration information setting device and one or more switching hubs, for setting VLAN configuration information of the switching hubs, is proposed. When a terminal is added to or removed from an Ethernet port of a switching hub by the user, a VLAN alteration request section of the switching hub detects the event, and a VLAN alteration request is transmitted to the automatic VLAN configuration information setting device. In a database of the automatic VLAN configuration information setting device, VLAN detailed information concerning all the VLANs managed by the automatic VLAN configuration information setting device is stored. A VLAN configuration instruction text editing section of the automatic VLAN configuration information setting device edits a VLAN configuration instruction text (an instruction scenario) by referring to the VLAN alteration request and the VLAN detailed information. The VLAN detailed information stored in the database is updated according to the VLAN configuration instruction text, and the VLAN configuration information of the switching hub is updated according to the VLAN configuration instruction text, thereby VLAN configuration information of the switching hubs is automatically set and updated without efforts by network administrators.
