图1 配置802.1X认证组网图
用户接入WLAN网络,使用802.1X客户端进行认证,输入正确的用户名和密码后可以无线上网。且在覆盖区域内移动发生漫游时,不影响用户的业务使用。

AC侧配置的RADIUS共享密钥需要和服务器侧保持一致。
建议在与AP直连的设备接口上配置端口隔离,如果不配置端口隔离,尤其是业务数据转发方式采用直接转发时,可能会在VLAN内形成大量不必要的广播报文,导致网络阻塞,影响用户体验。
隧道转发模式下,管理VLAN和业务VLAN不能配置为同一VLAN,且AP和AC之间只能放通管理VLAN,不能放通业务VLAN。

完成配置后,用户可通过无线终端搜索到SSID为wlan-net的无线网络。
用户关联到无线网络上后,无线PC能够被分配相应的IP地址。
在STA上使用802.1X客户端进行认证,输入正确的用户名和密码后,STA认证成功,正常访问WLAN网络。需要根据设置的认证方式PEAP对客户端进行相应的配置。
Windows 7系统下的配置
进入管理无线网络页面,单击“添加”,选择手动创建网络配置文件,添加SSID为wlan-net,并选择认证方式为WPA2-企业,加密使用的算法AES,单击“下一步”。
单击“更改连接设置”,进入“无线网络属性”界面,选择“安全”页签,单击“设置”,取消勾选“验证服务器证书”(此处不验证服务器证书),单击“配置”,取消勾选“自动使用Windows登录名和密码”,单击“确定”。
单击“确定”,返回“无线网络属性”界面,单击“高级设置”,在“高级设置”界面,勾选“指定身份验证模式”,并选择身份验证模式为“用户身份验证”,单击“确定”。
无线用户接入后,在AC上执行命令display access-user access-type dot1x,可以查看到认证类型为“802.1X”的用户中,名为“huawei”的用户已成功上线。
