标题：CCIE
简介
  思科认证网络专家项目（CCIE Program）为网络技术设立了一个专业标准，被业界广泛认可。拥有CCIE认证被认为是具有专业网络技术知识和丰富工作经验的最好证明　
CCIE(思科认证互联网专家)持有者占思科认证总人数还不足3%，全球网络从业者的1%不到（思科官方数据）。Cisco认证主要提供工程师在今日快速变动的网络环境中驾驭Cisco设备所需的专业知识。CCIE是Cisco（除了新推出的CCA以外）最高级技术能力的认证，位于Cisco金字塔认证体系中塔尖，也是IT界公认的最权威、最受尊重证书之一，2003年被评为全球十大IT认证榜首，具有IT终极认证的美称。取得CCIE证书除了整个行业的认同之外，CCIE也是你不断持有最新网络知识的指标；你将会在你的专业技术领域中成为一位最具竞争力的人[1]​
CCIE认证分active和inactive两种状态，Cisco公司为了让CCIE能够跟踪新技术，并保持CCIE的专家水平，从通过CCIE认证开始，每二年就要进行一次重认证，否则你虽然仍然拥有你的CCIE number,但是你的状态就从active变成inactive，相应的享有在cisco公司赋予的一些权利就没了，但是CCIE号码是永久保留。苛刻的认证规则使CCIE成为IT业界中含金量最高的证书之一，当然也成了最受尊重、最难取得的证书之一。　
Cisco公司从1993年开设CCIE考试，截止到2013年1月，全球共有CCIE 36000多名(当前号码减去1024等于全球通过人数)，中国大陆共有CCIE 近6000人.(CCIE人数统计是现在CCIE号码减去1024就是全球CCIE人数)CCIE号是从CCIE#1024开始算起的。为了纪念CCIELab这个艰辛的考试，思科确定：CCIE Lab考试本身就是一个CCIE#号（所以CCIE Lab考试就被冠于第一个CCIE#1024）所以第一位通过CCIE的考生是CCIE#1025（Stuart Biggs）然而Stuart Biggs本人当时就是思科CCIE考试的考官，所以第一位通过CCIE非cisco的考生是CCIE#1026 （Terry Slattery）【Netcordia的CEO】
获得CCIE认证不仅证明你的技术达到专家水平，得到业界认可与肯定，更是一种荣誉的象征，一种自我价值的体现。获得CCIE认证成为每位网络技术人员的梦想。Cisco公司为了让客户获得专家级技术支持，在其认证代理体系中规定金银牌认证代理商必须拥有一定数量的CCIE，这直接刺激了对CCIE的需求，在1999年期间，在中国大陆CCIE的年薪高达80万RMB。在系统集成项目中，许多业主提出承包商必须拥有CCIE认证专家，才有资格承接项目，由此可见CCIE专家在业界中的认可程度。
通过苛刻的CCIE认证后，您将获得一个CCO帐号，直接得到Cisco 二级专家的支持，享受CCIE拥有的特权。如果您打算技术移民，通过CCIE认证可以获得额外的加分，在中国通过的CCIE超过半数已经移民到国外。CCIE在美国年薪可达15万美元，还不包括股票期权和其他福利，在中国大陆，一位CCIE的年薪一般在10万元以上，如果加上奖金及其他福利将远远超过这个数目。
要想获得苛刻的CCIE认证，必须先通过笔试，获取资格后才可以参加实验考试。通过了实验才最终成为CCIE。学习并获得CCIE认证途径大致有两种：第一，自学。要想通过自学方式获取CCIE认证您必须要有两年以上的工作经验，有充足的时间和精力，并要有一个完善的实验环境，此外最重要的是您必须具备坚忍不拔的毅力与永不放弃信念。第二，参加培训。找一家货真价实的培训机构利用业余或集中时间参加培训，充分利用培训机构的实验设备，在良好的学习氛围下，学员之间不但可以互相交流技术更重要的是还可以得到培训机构的CCIE专家辅导，提高学习效率，这是一种事半功倍的途径。    
程及考试
CCIE 认证是Cisco认证体系中最顶级的证书。要取得CCIE认证证书，需要取得以下课程考试：
1．CCIE资格考试（即笔试，2.5小时）考试费：350美元
2．CCIE实验考试（8小时 TS+Lab） 考试费：1500美元，北京考点为RMB10335元
笔试部分考试在中国各个城市基本都能考，而实验室部分考试在世界范围内只有10个考场：研究三角园区（美）、圣何塞（美）、悉尼（澳）、香港（中）、北京（中）、班加罗尔（印）、东京（日）、布鲁塞尔（比）、圣保罗（巴）、迪拜（阿）。

路由交换认证介绍：
路由和交换领域的CCIE认证资格表示网络人士在不同的LAN、WAN接口和各种路由器、交换机的联网方面拥有专家级知识。R&S 领域的专家可以解决复杂的连接问题，利用技术解决方案提高带宽、缩短响应时间、最大限度地提高性能、加强安全性和支持全球性应用。考生应当能够安装、配置和维护LAN、WAN和拨号接入服务。再认证CCIE认证有效期为两年，且必须在之后每两年进行再认证。　要进行再认证，请在认证过期之前通过下列考试之一： 　通过任何一门提供的642-XXX Professional（资深工程师）级别考试； 　通过任何一门提供的CCIE笔试； 　通过提供的CCDE笔试或提供的CCDE实践考试； 　通过思科认证架构师（CCAr）面试和CCAr委员会审核，延长较低等级认证的有效期。 　未能在再认证期限之前通过资格考试或实验考试的CCIE和CCDE专业人士，将被置于暂缓状态，他们的雇主也会被告知这一情况。对处于暂缓状态的CCIE和CCDE专业人士，在他们的专家级别认证永久失效之前，将有一年时间来通过需要的考试或实验考试。失效了的CCIE和CCDE专业人士将失去所有利益，并且必须再次通过CCIE笔试和实验考试或CCDE笔试和实践考试。 　获取或再认证CCIE、CCDE或CCAr将自动延长您的入门级、工程师、资深工程师、其他专家级别认证或专业化认证的有效期，至最新获得的CCIE、CCDE或CCAr认证过期日。Exam Sections and Sub-task Objectives
