Cisco 2950G 802.1X+AD+CA+IAS进行802.1x身份验证

802．1x身份验证要求：1. 交换机支持802.1X协议。2. 有一台RADIUS服务器。3. 一台客户端。网络拓扑： 验证方式： PEAP验证：使用证书＋AD用户集成认证;环境： Operation System: Windows 2003 enterprise edition Radius Server: windows IAS(Internet 验证服务，windows组件中安装) CA Server: Windows CA证书服务(windows组件中安装) Radius Client: Windows自带。（网络连接->属性->验证），如果没有“验证”选项卡，则是相关服务没有启用。（开始->运行->services.msc->启动” Wireless Zero Configuration”服务）配置：1. 安装域，域名暂时定为：test.com。过程略，查看相关文档2. 安装IIS(Internet信息服务),IAS,CA：控制面板－>添加/删除程序->安装windows组件,如图:





注意先安装IIS->CA->IAS,顺序不能乱了.3. 配置CA:配置过程略,参考相关资料.

b) 新建立”RADIUS客户端”:



c) 新建访问策略







d) 修改策略属性





6. 客户端设置:a) 配置网络连接 b) 设置为自动获取IP7. 基本上,已经设置完毕.用户加入域后,登录域时自动下载证书.a) 如果有证书,则将获取相应VLAN的IP.b) 如果没有IP,将获取guest-vlan的IP.8. 一些配置步骤都已经省去,对于做网络的人来说,那些步骤应该不是什么问题吧.呵呵.有问题,有时再联系.我的邮件:define.chang@gmail.com MSN:autonavi@live.cn本文出自 “define_myself” 博客，转载请与作者联系！
