问题描述：

有两台VAC，一台是办公网AP正常上线，一台是生产网虚拟AP上线，现在有一台AP在生产网不上线，

ap两个接口地址1（办公网）：10.131.246.53 （生产网）：172.28.196.52

生产网AC地址： 172.28.1.243

帮忙看下debug什么意思

您好，删除wlan capwap discovery-policy unicast命令

通常情况下AP可以通过单播、组播及广播三种方式发现AC并建立CAPWAP或LWAPP隧道。配置了这个命令就是开启单播发现策略功能，AC只对发送单播Discovery request报文的AP进行响应，不对发送组播、广播Discovery request报文的AP进行响应，即只允许单播发现的AP与AC建立CAPWAP或LWAPP隧道连接。

从这里我们就找到了问题的根因，AP广播发送请求给AC，由于AC开启了单播发现策略功能，所以AC不给AP回应，因此AP无法注册。

参考以下帖子：

https://zhiliao.h3c.com/Theme/details/216422

https://zhiliao.h3c.com/Theme/details/24941

通过在AP上的debug capwap可以看到，AP同时向两个AC发起discover请求并收到回应，并且向level优先级高的AC发起了join请求，但是join失败。

此时我们发现，在备AC上本体的模板下配置了level 2，本体在主AC正常上线，但是分体在两台AC上都没有配置优先级，分体根据discover回应的信息确认备AC的AP负载小，故向备AC发起join，此时备AC查看本体拓扑关系，本体不在线，故拒绝分体上线。

在主备AC上将本体和分体的优先级配置一致。

终结者本体和分体存在对应关系，需要确保AC上其优先级配置一致。
