摘要

PROBLEM TO BE SOLVED: To provide a network switching apparatus to easily actualize a coarse communication check among different local area networks (LAN's) by providing a virtual LAN site within the apparatus.;SOLUTION: The network switching apparatus includes a signal determining device 1 for determining a testing data transmitted and received via lines among VLAN sites 100, a testing signal generating device 2 for generating testing data as a response of the testing data or testing data for requesting transmission via the lines, and a switching control device 3 for controlling switching transmission of this testing data. The testing signal generating device 2 includes a virtual VLAN executing part 21 for processing the testing data by executing processes considering the VLAN site 100 as the virtual VLAN site based on testing scenario data 21a for defining the VLAN site 100 for processing the testing data and a testing signal determining part 22 for identifying the virtual VLAN site for processing the testing data and determining sharing to this virtual VLAN site based on a testing VLAN table 22a.;COPYRIGHT: (C)2010,JPO&INPIT
