摘要

PROBLEM TO BE SOLVED: To solve problems of a conventional method for preventing illegal connection and build-up/operation management of a virtual LAN requires capital investment on an exclusive management unit and further requires expert intelligence and much labor which leads to a significant burden on a network manager.;SOLUTION: As shown in Figure 1, each port of the hub of this invention is provided with a 1st switch 11 that permits the user or sets the type of a virtual LAN and a 2nd switch 12 that can set the number of the virtual LAN. The two switches, namely the 1st switch 11 and the 2nd switch 12, are used to make setting of each port, and depression of a 3rd switch 13 allows the hub to read the setting state resulting in configuring a virtual LAN. Furthermore, a cover 22 with a lock mechanism is provided to a setting switch section in the front face, and by inserting a key 20 to a lock 21 of the hub 1 and turning the key 20, the lock 21 is unlocked so as to allow the cover 22 with the lock mechanism to open. Thus, operation of the hub by other people than the manager can be prevented and connection without permission can be avoided.;COPYRIGHT: (C)2001,JPO
