WDS

特性:

方便网络部署、安装,实现灵活组网。低成本,高性能,扩展性好

定义:
WDS :Wireless Distribution System:通过无线链路连接两个或者多独立的有线局域网或者无线局域网,组建一个互通的网络实现数据访问


使用规则:
无线网桥:射频上提供WDS业务的功能实体,可以说网桥就是AP,而这种AP并不能单独工作,需要AC配合将AP配置为无线网桥,AP才能提供无线连接服务

VAP是虚拟(Virtual)AP的意思
当一个服务集(service-set)被绑定到AP射频上时,即生成一个VAP,一个VAP就是一个无线信号。一个AP的射频可释放出最多16组VAP,即16个不同名称(SSID)的无线信号。

在WDS网络中,又分业务型VAP和网桥型VAP
业务型VAP:AP为STA提供的WLAN业务接入点,也称服务性VAP
网桥型VAP:AP网桥上为邻居网桥提供的与之建立无线虚链路的接入点

WVL(Wireless Virtual Link):两个分属不同AP网桥的网桥型VAP建立起的连接
管理型WVL:用于AP间管理,是搭建WDS环境的基础
业务型WVL:用于传输用户的实体业务

WDS下AP的工作模式(root/middle/leaf)root AP-middle AP,Middle AP-leaf AP,Leaf AP-STA

连接方式

与AC连接的AP必须设置为root 模式,而root AP下既可以连接middle AP又可以直连leaf AP,middle AP下只可以连接leaf AP

技术分享

白名单

AC上的AP白名单用于AP能否在AC注册上线的控制。
而网桥白名单则用于控制两个AP之间WDS无线网桥的建立。
Root AP下的网桥白名单用于控制middle和leaf类型的AP接入。
middle AP下的网桥白名单用于控制Leaf AP的接入。
