无线局域网WLAN（Wireless Local Area Network）是一种无线计算机网络，使用无线信道代替有线传输介质连接两个或多个设备形成一个局域网LAN（Local Area Network），典型部署场景如家庭、学校、校园或企业办公楼等。
WLAN是一个网络系统，而我们常见的Wi-Fi是这个网络系统中的一种技术使用WLAN网络中由两个关键的设备，AP和AC。AP是无线访问接入点，，一般来说一个网络中都有多个AP。AC是无线控制器，主要功能是对AP进行统一的管理，负责把来自不同AP的数据进行汇聚并接入Internet。
网络拓扑图：
无线网络的配置过程：
1.基础配置（VLAN，IP地址）
2.DHCP服务器和中继
3.AC中绑定AP
4.配置SSID模块、安全模块、VAP模块
5.VAP绑定SSID和安全模块
6.VAP关联AP组
7.测试

3.AC绑定AP
先查看AP是否获取到了IP地址
在AC处抓包，显示有AP的请求报文
查询APmac地址

[AC6005-wlan-view]quit
#配置出去的默认路由
[AC6005]ip route-static 0.0.0.0 0 192.168.40.254
#这里要先进一下三层vlan
[AC6005]int vlan 10
[AC6005]quit
查看AP是否上线
4.配置SSID模块、安全模块、VAP模块
[AC6005]wlan

6.VAP关联AP组
[AC6005-wlan-vap-prof-40]quit
[AC6005-wlan-view]ap-group name 40
[AC6005-wlan-ap-group-40]regulatory-domain-profile 40
Warning: Modifying the country code will clear channel, power and antenna gain c
onfigurations of the radio and reset the AP. Continue?[Y/N]:y
[AC6005-wlan-ap-group-40]vap-profile 1 wlan 2 radio all
Error: The VAP profile does not exist.
[AC6005-wlan-ap-group-40]vap-profile 40 wlan 2 radio all
Info: This operation may take a few seconds, please wait...done.
这个时候就可以查看到效果了
7.测试
连接成功
看一下连通性
这个时候我们的WLAN就算配置完成了
