AP三层注册无法上线

AC和DHCP服务器旁挂交换机，交换机下联AP

AP三层注册无法上线

AP三层注册无法上线

查看AP可以正常获取到对应地址，但是无法上线，看DHCP服务器也下发了Option 43属性

测试在AP上手动指定AC地址也可以正常上线，debug wlan capwap all 查看交互发现AP获取地址后还是想组播地址发送上线请求。

怀疑option 43下发的有问题，现场DHCP服务器为微软服务器，查看对应Option 43配置

发现对应的二进制中写错了Option 43属性

改成如下HEX后AP正常上线

按照如上配置Option 43 HEX属性后正常。
