WA2620E-F射频口丢失导致注册不上线问题分析

WX6108E下一个WA2620E-F注册不上线，替换另一个WA2620E-F到接入交换机相同端口下测试注册正常。

现场反馈WA2620E-F的interface Vlan-interface1能正常获取IP地址，在WA2620E-F上Ping WX6108E正常，且换另一个WA2620E-F到接入交换机相同端口下测试注册正常，排除网络问题，检查WX6108E配置无误。

在AC上收集debugging wlan lwapp all信息，发现注册报文被AC丢弃：

判断WA2620E-F的射频接口应该有问题，收集WA2620E-F启动过程和配置发现：

System application is starting...
This device have lost some radio card!!!Please return for repair!!!
User interface con0 is available.

WA2620E-F射频口丢失，此故障AP启动后上报信息，AC发现没有Radio 2的数据，认为配置错误，所以将报文丢弃。

interface WLAN-Radio1/0/1  //配置中只有射频口1，没有射频口2

WA2620E-F射频接口2丢失，返备件。

V5 AP射频卡丢失后还可以进入系统操作；V7 AP射频卡丢失会直接重启，不能进入系统。
