CCIE簡介：什么是CCIE
CCIE簡介之一：CCIE全稱Cisco Certified Internetwork Expert—— Cisco認證互聯網專家， 是美國Cisco公司于1993年開始推出的專家級認證考試。被公認為IT業最權威的認證,是全球網絡互連領域中最高級別的認證證書。這個認證主要提供工程師在今日快速變動的網絡環境中駕馭Cisco設備所需的專業知識。是Cisco的最高級技術能力認證，位于Cisco金字塔認證體系中塔尖，也是IT界公認的最權威、最受尊重證書之一，2003年被評為全球十大IT認證榜首，具有IT終極認證的美稱。
CCIE簡介之二:CCIE 認證是目前Cisco認證體系中最頂級的證書。要取得CCIE認證證書，需要取得以下課程考試：
1、CCIE資格考試（即筆試，2.5小時） 考試費：￥3000
2、CCIE實驗考試（一天） 考試費：￥12000
3、CCIE面試（英文）
筆試部分考試在中國各個城市基本都能考，而實驗室部分考試在世界范圍內只有9個考場：研究三角園區（美）、圣何塞（美）、悉尼（澳）、香港（中）、北京（中）、班加羅爾（印）、東京（日）、布魯塞爾（比）、圣保羅（巴）、。
CCIE簡介之三：CCIE目前在考的共分為5類：
Routing & Switching(R&S) 路由交換CCIE
Service Provider(SP) 電信運營商CCIE
Security 安全CCIE
Voice 語音CCIE
Storage Networking 存儲CCIE
CCIE簡介之四：CCIE認證的有效期為兩年
如果以通過CCIE試驗考試重認證只需要進行筆試重認證；如果在證書沒有過期時進行重認證那么有效日期將累加
重認證 重新參加筆試
