CCIE简介之一：CCIE全称Cisco Certified Internetwork Expert—— Cisco认证互联网专家， 是美国Cisco公司于1993年开始推出的专家级认证考试。被公认为IT业最权威的认证,是全球网络互连领域中最高级别的认证证书。这个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。是Cisco的最高级技术能力认证，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。

CCIE简介之二:CCIE 认证是目前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：￥3000

2、CCIE实验考试（一天） 考试费：￥12000

3、CCIE面试（英文）

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9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）、。

CCIE简介之三：CCIE目前在考的共分为5类：

Routing & Switching(R&S) 路由交换CCIE

Service Provider(SP) 电信运营商CCIE

Security 安全CCIE

Voice 语音CCIE

Storage Networking 存储CCIE

CCIE简介之四：CCIE认证的有效期为两年

如果以通过CCIE试验考试重认证只需要进行笔试重认证；如果在证书没有过期时进行重认证那么有效日期将累加

重认证 重新参加笔试
