The ether exchange technology principal aspect isvirtual local area work VLAN, it uses the switchboard gathers theworkstation and the server at in the logical concept group, is onekind through the local area work in equipment logic place, but is not a physical division webpage, thus realizes the hypothesized workteam39。s technology The content contained covers has set up the localarea work, main knowledge as follows: The switchboard basicdisposition and the use, based on the VLAN division, based on the portVLAN disposition, as well as between VLAN the disposition method whichretransmits through the third switchboard, port TRUNK attributerelated knowledge and the port TRUNK attribute disposition step, theswitchboard CONSOLE mouth disposition, as well as the CONSOLE mouthdisposition content and the environment, the monly used orderintroduction, registers switchboard using TELNET the sequence ofoperation.
