组网需求
集中式转发架构下，AC旁挂在L3 switch上，L3 switch做DHCP server为AP、Client和Host分配IP地址。需要实现无线客户端Client通过AP连接到AC上，并能与有线客户端Host互相访问，具体要求如下：
无线客户端Client通过VLAN 200接入网络，有线客户端Host通过VLAN 300接入网络；
AC属于VLAN 100，AP属于VLAN 400，AC和AP之间跨三层网络建立连接。
L2 switch 1通过PoE方式给AP供电。
配置思路
- 在L3 switch上开启DHCP server功能，AP、无线客户端Client和有线客户端Host都能通过DHCP server自动获取IP地址。
- 在AC上配置缺省路由下一跳为L3 switch。
- 在DHCP server上配置AP通过option方式获取AC的IP地址完成三层注册。
- 在L2 switch 1上开启PoE功能，为AP设备供电。
- 在AC上配置无线服务，确保Client可以通过配置的无线服务接入网络。
- 配置AP的序列号时请确保该序列号与AP唯一对应，AP的序列号可以通过AP设备背面的标签获取。
- 在L2 switch 1上开启PoE功能，为AP设备供电。
- 配置L2 switch 1和AP相连的接口为Access口。

配置AC
(1) 配置AC的接口
# 创建VLAN 100及其对应的VLAN接口，并为该接口配置IP地址。AP将通过DHCP option43方式获取该IP地址与AC建立CAPWAP隧道。
<AC> system-view
[AC] vlan 100
[AC-vlan100] quit

[AC-Vlan-interface100] ip address 192.168.10.1 255.255.255.0
[AC-Vlan-interface100] quit
# 创建VLAN 200，AC需要使用该VLAN转发无线客户端数据报文。
[AC] vlan 200
[AC-vlan200] quit
# 配置AC和L3 switch相连的接口GigabitEthernet1/0/1为Trunk类型，禁止VLAN 1报文通过，允许VLAN 100和VLAN 200通过。

# 设置AP的序列号为210235A1GQB147031200。
[AC-wlan-ap-officeap] serial-id 210235A1GQB147031200
# 进入AP的Radio 1视图，并将无线服务模板1绑定到Radio 1上，并指定客户端上线的VLAN为VLAN 200。
[AC-wlan-ap-officeap] radio 1
[AC-wlan-ap-officeap-radio-1] service-template 1 vlan 200
