H3C WX系列AC+Fit AP 802.1x无线认证和IAS配合

 

802.1x协议仅仅提供了一种用户接入认证的手段,并简单地通过控制接入端口的开/关状态来实现,这种简化适用于无线局域网的接入认证、点对点物理或逻辑端口的接入认证,而在可运营、可管理的宽带IP城域网中作为一种认证方式具有极大的局限性

 

H3C WX系列AC+Fit AP 802.1x无线认证和CAMS配合

一、组网需求

本配置举例中的AC使用的是WX5002无线控制器,AP使用的是WA2100无线局域网接入点。AC的IP地址为192.168.1.50/24,Radius Server的IP地址为8.1.1.4/8,AP和Client通过DHCP服务器获取IP地址。

本典型配置举例简化组网为两台PC(Client)以及一台Fit AP和无线控制器AC通过IP网络相连。

2. 在IAS上配置802.1X认证项:
配置Radius客户端:
 
ias上的802.1x认证域

配置远程访问策略:

配置远程访问策略

编辑拨入配置文件:

拨入配置

IAS相关的其他配置(比如采用证书认证时需要的证书、AD中的用户等)这里不再详细说明,请参考windows相关帮助文档

注意事项
(1)        如果采用EAP-TLS/EAP-PEAP认证,需要IAS服务器上有服务器验证证书。

(2)        还需要在AD中配置认证用户,并允许该用户远程拨入(windows创建一个用户后,缺省是禁止拨入的)。

相关配置请参考windows IAS配置说明。
