为什么我收不到任何一个ARP请求的答案？

Question

我工作的嵌入式设备上的本地网络，RJ45，当系统发出一个ARP请求知道网关的MAC地址，根本没有答案。

中连接

如果我清楚在我的Windows ARP表中，Windows询问一模一样ARP请求，并得到一个答案！

我嗅的分组和请求分组内的唯一的区别是在嵌入式设备上的0拖车在分组的末尾，并且目标MAC地址为FF：FF：FF：FF：FF：FF其中窗户一个是00：00：00：00：00：00（维基百科似乎是说，它应该是ffffffffff）

我试图改变MAC地址的情况下，我的网关禁止MAC由于ARP垃圾邮件，但它不会改变任何东西。我也有DHCP IP和静态IP，同样的问题...

Answer 1

在实际上，这是与TX一个问题，即极性反转，导致这些问题。

我反转的极性和现在它完美。
