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。

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。# 在接入交换机Switch_1上创建VLAN100(管理VLAN)。Switch_1连接RU_1的接口GE0/0/1和连接中心AP的接口GE0/0/2加入VLAN100。

- 配置中心AP作为DHCP服务器,为STA和RU分配IP地址# 配置基于接口地址池的DHCP服务器,其中,VLANIF100接口为RU提供IP地址,VLANIF101为STA提供IP地址。DNS服务器地址请根据实际需要配置。常用配置方法如下:
- 接口地址池场景,需要在VLANIF接口视图下执行命令dhcp server dns-list ip-address &<1-8>。
- 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>。

ap auth-mode命令缺省情况下为MAC认证,如果之前没有修改其缺省配置,可以不用执行ap auth-mode mac-auth。
