<p><P>PROBLEM TO BE SOLVED: To facilitate an inspection of a communication range of a VLAN that is set in a network. <P>SOLUTION: A primary-table generation means 310 refers to a VLAN setting information aggregation and a network configuration information aggregation which are stored in a VLAN setting information storage device 110, so as to prepare a primary table and store it in a primary-table storage means 320. The primary table is a preprocessing table for a secondary table required for analyzing the communication range of the VLAN. A secondary-table generation means 330 generates a secondary table from the primary table so as to store it in a secondary-table storage device 130. When a VLAN-ID of equipment as an analysis target is inputted, a VLAN communication range analysis means 140 refers to the secondary table so as to derive a range communicable with the VLAN-ID of the equipment. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
