摘  要
從實踐出發(fā)，本論文主要以“華為交換機”為例介紹交換機的基本工作原理，以太網(wǎng)交換技術(shù)的一個主要方面是虛擬局域網(wǎng)VLAN，它使用交換機將工作站和服務器聚集在邏輯概念的組中，即是一種通過將局域網(wǎng)內(nèi)的設(shè)備邏輯地，而不是物理的劃分一個網(wǎng)段，從而實現(xiàn)虛擬工作組的技術(shù).內(nèi)容含蓋了組建局域網(wǎng)，其中主要的知識點如下： 交換機的基本配置和使用，基于VLAN的劃分，基于端口VLAN的配置，以及VLAN之間通過第三層交換機轉(zhuǎn)發(fā)的配置方法，端口TRUNK屬性的相關(guān)知識和端口TRUNK屬性的配置步驟，交換機CONSOLE口的配置，以及CONSOLE口的配置的內(nèi)容和環(huán)境，常用的命令的介紹， 利用TELNET登錄交換機的操作步驟。

From the practice, the paper mainly take "3com switchboard" for the example introducing the switchboard the basicprinciple of work. The ethernet exchange technology principal aspect isvirtual local area network VLAN, it uses the switchboard gathers theworkstation and the server at in the logical concept group, is onekind through the local area network in equipment logic place, but is not a physical division webpage, thus realizes the hypothesized workteam's technology The content contained covers has set up the localarea network, 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 commonly used orderintroduction, registers switchboard using TELNET the sequence ofoperation.
