大中型WLAN网络简介本文介绍的WLAN网络是指利用频率为2.4GHz或5GHz的射频信号作为传输介质的无线局域网，相对于有线网络的铺设成本高，不便于网络调整和扩展、位置固定，移动性差等缺点，WLAN网络以其低廉的铺设成本、便捷的网络调整和扩展、灵活的可移动性获得了越来越广泛的应用。大中型WLAN网络定位为大中型企业总部、大型分支机构、高校、机场等场所。组网需求如图1，AC连接园区出口网关Router，并通过PoE交换机与AP连接，PoE交换机为AP供电。用户希望通过WLAN部署，提供名为“test”的无线网络方便用户随时随地接入。同时，用户希望通过路由器Router来做DHCP Server为用户提供10.10.10.0/24网段的IP地址，并在AC上对用户进行集中控制和管理。图1 配置中型网络WLAN基本业务组网图
配置思路采用如下的思路配置中型网络的WLAN基本业务：配置AP、AC和上层网络设备之间实现网络互通。在AC上配置基于接口的DHCP服务器为AP分配IP地址，同时配置AC作为DHCP中继，由AC连接的路由器为STA分配IP地址。配置WLAN基本业务，保证用户能够通过WLAN网络接入Internet。操作步骤在AC上配置NAC模式为统一模式（缺省值，不需配置）。配置SwitchA和AC，使AP与AC之间能够传输CAPWAP报文#
