H3C无线控制器-双链路备份技术
【拓扑】
【需求】
AP和无线终端是通过DHCP方式获取IP
AP的网关在HJ
无线终端的网关在Core
无线业务是集中转发
AC1和AC2之间使用双链路备份技术来提高冗余
VLAN20：10.0.20.0/24（DHCP服务器）
VLAN25：10.0.25.0/24（AC）
VLAN12：10.0.12.0/24（互联地址）
VLAN60：10.0.60.0/24（AP管理地址）
VLAN70：10.0.70.0/24（AP管理地址）
VLAN100：10.0.100.0/24（office业务地址）
VLAN110：10.0.110.0/24（prd业务地址）

【效果】
模拟AC 1故障，将AC 1的Vlan-interface25接口关闭，等待一段时间（根据CAPWAP隧道保活时间而定，默认为30秒，集中转发模式时，期间流量会中断），AP会切换至AC 2上线，在AC 2上通过display wlan ap all命令查看AP的状态为R/M。
capwap隧道定时器过期后
当AC1从故障恢复后，需要等待10分钟，AP才能重新连接到AC1上。
