1  组网及说明

    本文档介绍IPv6的802.1X远程认证典型配置举例。

1.1 配置前提

    本文档适用于使用Comware V7软件版本的无线控制器和接入点产品，不严格与具体硬件版本对应，如果使用过程中与产品实际情况有差异，请参考相关产品手册，或以设备实际情况为准。

    本文档中的配置均是在实验室环境下进行的配置和验证，配置前设备的所有参数均采用出厂时的缺省配置。如果您已经对设备进行了配置，为了保证配置效果，请确认现有配置和以下举例中的配置不冲突。

    本文档假设您已了解IPv6基础、WLAN接入、WLAN用户安全、WLAN用户接入认证和802.1X的相关特性。

1.2  组网需求

    如图1所示组网，Switch作为DHCP server为AP和Client分配IP地址，采用iMC作为RADIUS服务器对用户进行认证、授权和计费，要求：

·   对无线用户进行远程802.1X认证。

·   客户端链路层认证使用开放式系统认证。

·   通过配置客户端和AP之间的数据报文采用802.1X身份认证与密钥管理来确保用户数据的传输安全。

·   加密套件采用CCMP。

图1 远程802.1X认证组网图

 

1.3  配置注意事项

·   配置AP的序列号时请确保该序列号与AP唯一对应，AP的序列号可以通过AP设备背面的标签获取。

·  为了使服务器对用户授权信息进行动态修改或强制用户下线，必须开启RADIUS session control功能。

2  配置步骤

2.1  配置AC

(1) 配置AC的接口

# 创建VLAN 100以及对应的VLAN接口，并为该接口配置IP地址。AP将通过该VLAN与AC建立CAPWAP隧道。
