路由器的一般配置和簡單調(diào)試(3)

時間: 若木635 分享

  外型尺寸的選擇

  如果網(wǎng)絡(luò)已完成樓宇級的綜合布線,工程要求網(wǎng)絡(luò)設(shè)備上機式集中管理,應(yīng)選擇19英寸寬的機架式路由器,如Cisco2509、華為2501(配置同Cisco2501)。如果沒有上述需求,桌面型的路由器如Intel的8100和Cisco的1600系列,具有更高的性能價格比。

  協(xié)議的選擇

  由于最初局域網(wǎng)并沒先出標(biāo)準(zhǔn)后出產(chǎn)品,所以很多廠商如Apple和IBM都提出了自己的標(biāo)準(zhǔn),產(chǎn)生了如AppleTalk和IBM協(xié)議,Novell公司的網(wǎng)絡(luò)操作系統(tǒng)運行IPX/SPX協(xié)議,在連接這些異構(gòu)網(wǎng)絡(luò)時需要路由器對這些協(xié)議提供支持。Intel9100系列和9200系列的路由器可提供免費支持,3Com的系列路由產(chǎn)品也提供較廣泛的協(xié)議支持。

  路由器作為網(wǎng)絡(luò)設(shè)備中的“黑匣子”,工作在后臺。用戶選擇路由器時,多從技術(shù)角度來考慮,如可延展性、路由協(xié)議互操作性、廣域數(shù)據(jù)服務(wù)支持、內(nèi)部ATM支持、SAN集成能力等。另外,選擇路由器還應(yīng)遵循如下基本原則:即標(biāo)準(zhǔn)化原則、技術(shù)簡單性原則、環(huán)境適應(yīng)性原則、可管理性原則和容錯冗余性原則。對于高端路由器,更多的還應(yīng)該考慮是否和如何適應(yīng)骨干網(wǎng)對網(wǎng)絡(luò)高可靠性、接口高擴(kuò)展性以及路由查找和數(shù)據(jù)轉(zhuǎn)發(fā)的高性能要求。高可靠性、高擴(kuò)展性和高性能的“三高”特性是高端路由器區(qū)別于中、低端路由器的關(guān)鍵所在。

  CISCO路由器初始配置簡介

  很多初學(xué)路由器知識的網(wǎng)友對路由器的初始配置可能感到很陌生,本人在初學(xué)時也很困惑,因為一下出來很多提問不知如何是好,下面將最近剛調(diào)試的一臺CISCO3640的初始配置整理出來與各位網(wǎng)友交流,如有疏漏之處,還請大家指正。

  1.用CISCO隨機帶CONSOLE線,一端連在CISCO路由器的CONSOLE口,一端連在計算機的COM口。

  2.打開電腦,啟動超級終端.為您的連接取個名字,比如CISCO_SETUP,下一步選定連接時用COM1,下一步選定第秒位數(shù)9600,數(shù)據(jù)位8,奇偶校驗無,停止位1,數(shù)據(jù)流控制無.最后選確定。

  3.打開路由器電源,這時超級終端將出現(xiàn)以下畫面:
