要求：
1. 交換機支持802.1X協議。
2. 有一臺RADIUS服務器。
3. 一臺客戶端。
網絡拓撲：
驗證方式：
PEAP驗證：使用證書＋AD用戶集成認證;
環境：
Operation System: Windows 2003 enterprise edition
Radius Server: windows IAS(Internet 驗證服務，windows組件中安裝)
CA Server: Windows CA證書服務(windows組件中安裝)
Radius Client: Windows自帶。（網絡連接->屬性->驗證），如果沒有“驗證”選項卡，則是相關服務沒有啓用。（開始->運行->services.msc->啓動” Wireless Zero Configuration”服務）
配置：
1. 安裝域，域名暫時定爲：test.com。過程略，查看相關文檔
2. 安裝IIS(Internet信息服務),IAS,CA：控制面板－>添加/刪除程序->安裝windows組件,如圖:![]()
意
先安裝IIS->CA->IAS,順序不能亂了.
3. 配置CA:配置過程略,參考相關資料.
4. CISCO 2950G-48-EI交換機配置:

Layer_4_2#
5. 配置IAS:
a) 打開IAS:
b) 新建立”RADIUS客戶端”:
c) 新建訪問策略
d) 修改策略屬性
6. 客戶端設置:
a) 配置網絡連接
b) 設置爲自動獲取IP
7. 基本上,已經設置完畢.用戶加入域後,登錄域時自動下載證書.
a) 如果有證書,則將獲取相應VLAN的IP.
b) 如果沒有IP,將獲取guest-vlan的IP.
