配置AC内漫游示例
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、WDS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，配置下发到AP，进而配置的功能在AP上生效。由于模板之间是存在各相互引用关系的，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AC对AP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6-6所示，AC为企业员工提供业务服务，AC分别连接AP_1和AP_2。
配置思路
采用如下的思路配置AC内漫游：
- 配置网络互通，使AP与AC之间能够传输CAPWAP报文。
- 配置AC作为DHCP服务器，为STA和AP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
纯组播报文由于协议要求在无线空口没有ACK机制保障，且无线空口链路不稳定，为了纯组播报文能够稳定发送，通常会以低速报文形式发送。如果网络侧有大量异常组播流量涌入，则会造成无线空口拥堵。为了减小大量低速组播报文对无线网络造成的冲击，建议配置组播报文抑制功能。配置前请确认是否有组播业务，如果有，请谨慎配置限速值。
- 业务数据转发方式采用直接转发时，建议在直连AP的交换机接口上配置组播报文抑制。
- 业务数据转发方式采用隧道转发时，建议在AC的流量模板下配置组播报文抑制。
- 管理VLAN和业务VLAN不能配置为同一VLAN。
在配置多个VAP模板，且多个VAP模板共用同一个service-vlan的场景下，如果配置数据转发方式为tunnel模式，则需要启动service-vlan间的Proxy ARP功能。
操作步骤
- 配置AP与AC之间网络互通
# 将接口Eth2/0/0和Eth2/0/1加入VLAN100（管理VLAN）、VLAN101和VLAN102（业务VLAN）。
建议在AC连接AP的接口Eth2/0/0和Eth2/0/1上配置端口隔离，如果不配置端口隔离，可能会在VLAN内存在不必要的广播报文，或者导致不同AP间的WLAN用户二层互通的问题。
