WLAN不同的特性和功能需要在不同类型的模板下进行配置和维护,这些模板统称为WLAN模板,如域管理模板、射频模板、VAP模板、AP系统模板、AP有线口模板、WIDS模板。当用户在配置WLAN业务功能时,需要在对应功能的WLAN模板中进行参数配置,配置完成后,须将此模板引用到AP组或AP中,配置才会自动下发到RU,进而配置的功能在RU上生效。由于模板之间是存在相互引用关系的,因此在用户配置过程中,需要提前了解各个模板之间存在的逻辑关系。模板的逻辑关系和基本配置流程请参见WLAN业务配置流程。
某小型企业为员工提供WLAN网络业务,由于场所面积不大,可以通过一台中心AP对RU进行管理。同时为了区分部门进行管理,不同部门的员工在不同的子网。企业希望员工在企业内部移动办公的同时网络业务不中断。
如图1所示,中心AP为企业员工提供业务服务,中心AP分别通过Switch_1和Switch_2连接area_1和area_2。
采用如下的思路配置中心AP内漫游:
配置项 | 数据 |
---|---|
DHCP服务器 | 中心AP作为DHCP服务器为STA和RU分配IP地址 |
RU的IP地址池 | 10.23.100.2~10.23.100.254/24 |
STA的IP地址池 | 10.23.101.2~10.23.101.254/24 |
中心AP的源接口IP地址 | VLANIF100:10.23.100.1/24 |
AP组 |
|
域管理模板 |
|
SSID模板 |
|
安全模板 |
|
VAP模板 |
|
建议在与RU直连的设备接口上配置端口隔离,如果不配置端口隔离,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。

- 全局地址池场景,需要在IP地址池视图下执行命令dns-list ip-address &<1-8>。
