当局域网出现了网络故障的时候，我们又不知道问题出现在哪里，这该怎么办呢？其实这时候我们就可以用局域网来找到出现网络故障的位置，然后进行问题的解决。所以接下来小编就来告诉你们在局域网内要怎么排查网络故障。
对于怎么在局域网内排除网络故障这个问题，虽然不是我们经常会遇到的，但是也是会遇到的。所以小编觉得这还是需要知道怎么解决的。那么接下来小编就来告诉你们怎么在局域网内排查网络故障。
1.先要了解拓扑结构，知道报错（网络不通）点的网络结构。有哪几个结点。结点与结点之间的网线端口心里要有数。能马上找到。然后，可以用ping 命令试着ping 一下报错点附近的电脑是否通。这样就可以判断是单个网络问题还是局部网络问题。

2.如果是单个网络问题，只要在电脑上看电脑网络设置即可。如果是局部问题。你得找到报错点最近的交换机。重启一下试试。
3.如果还没有解决，那就查一查网线的端口是不是好的。用检测网络的工具找到这条网线进行检查确认。1-2-3-6灯必须要亮才算是通的。

4.如果1-2-3-6有灯不亮，说明这网线或端口有问题，这时可以用测网工具2端都接上，看看整条网线的情况。试着重新做水晶头来解决问题。

5.如果网线没有问题，就需要看看交换机是否有问题。把最近的交换机换了。再用ping来测试。最麻烦的情况是：当一台电脑的网卡坏了并且引起网络故障时，你只得用ping IP（网关） -t 边ping网关，边一一拔网线。才能找到这台电脑。更换网卡后问题解决。另外，找到核心交换机，查看接出的网络端口是不是通的。

6.找到核心交换机，清一下ARP表。以防有IP冲突。再以管理员身份进入核心交换机，找到ARP表，删除所有的静态与动态表项。最后重新绑定ARP。以防IP冲突。
