华为配置中心AP内漫游示例
组网图形
配置流程
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。
组网需求
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。
配置思路
采用如下的思路配置中心AP内漫游：
- 配置网络互通，使RU与中心AP之间能够传输CAPWAP报文。
- 配置中心AP作为DHCP服务器，为STA和RU分配IP地址。
- 配置WLAN基本业务，保证用户能够连接到无线网络。
数据规划
| 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 |
|
配置注意事项
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。
操作步骤
- 配置Switch和中心AP，使RU和中心AP互通。
