组网需求

某医院通过部署敏捷分布式网络给医护人员提供WLAN接入服务，以满足医护人员办公的最基本需求。管理员希望终端在覆盖区域内移动发生漫游时，终端无感知，业务不中断。

配置思路
  1. 配置中心AP、RU和上层网络设备之间实现二层互通。
  2. 配置中心AP作为DHCP服务器为RU和STA分配IP地址。
  3. 配置RU上线。
  4. 配置WLAN业务参数，实现STA访问WLAN网络功能。
  5. 配置敏捷分布式SFN漫游。
配置注意事项
操作步骤
  1. 配置周边设备

    # 配置Router的接口GE1/0/0的IP地址，并配置指向STA网段的静态路由。 
    <span style="color:#333333"><span style="background-color:#dddddd"><Huawei> <strong>system-view</strong>
[Huawei] <strong>sysname Router</strong>
[Router] <strong>interface gigabitethernet 1/0/0</strong>
[Router-GigabitEthernet1/0/0] <strong>ip address 10.23.101.2 24</strong>
[Router-GigabitEthernet1/0/0] <strong>quit</strong>
[Router] <strong>ip route-static 10.23.101.0 24 10.23.101.1</strong></span></span>
  2. 配置中心AP与其它网络设备互通

    # 配置中心AP的接口GE0/0/1和GE0/0/2加入VLAN100（管理VLAN），GE0/0/24和GE0/0/25加入VLAN101（业务VLAN）。

[AP-GigabitEthernet0/0/25] <strong>quit</strong></span></span>
  3. 配置中心AP作为DHCP服务器为RU和STA分配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>。
    <span style="color:#333333"><span style="background-color:#dddddd">[AP] <strong>dhcp enable</strong>

[AP-Vlanif100] <strong>quit</strong>
[AP] <strong>interface vlanif 101</strong>

    # 在中心AP上离线导入RU，并将RU加入AP组“ap-group1”中。假设RU的MAC地址为60de-4476-e360，并且根据RU的部署位置为RU配置名称，便于从名称上就能够了解RU的部署位置。例如MAC地址为60de-4476-e360的RU部署在1号区域，命名此RU为area_1。

    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。

    举例中使用的RU为R240D，具有射频0和射频1两个射频。R240D的射频0为2.4GHz射频，射频1为5GHz射频。
