这以前time=1ms 不知道为什么最近老是不正常，在查看交换机上的线路时，所有的线路数据灯都是在狂闪，而打开网页时特慢，请大侠指教一二！我应该如何控制该局域网？如何查找出哪台电脑是否在下载东西或中毒在发数据包……请大侠明确指教！！！急！急
晕，我的问题对于一个企业网管应该不是很难，是他们没有看到，还是觉得我太笨……

172.0.0.1我这里ping不通；为什么……

问题解答：

所有端口灯狂闪,疑似网络中出现环回现象,建议检查你网络中是否存在环回.最简单的方法:逐个拔插,查看灯的闪烁状态,确认环回的位置,然后解决他.

用sinffer 应该就可以查出来...或者用P2P终结者之类的查看一下流量

就我的经验来说有两种可能性
1你的网线组抗有点高 出现了丢包的现象
2你的网卡该换了
你可以ping 172.0.0.1 看看如果没事就是线的毛病
