我有一个服务器与5个其他设备都插入到一个单一的交换机。 我可以ping所有设备，具有很好的ping时间（在0.6ms和0.9ms之间）。 但是，突然之间，到其中一个设备的ping时间显着增加（在20ms到80ms之间）。 当ping速率下降时，我们也会发现设备的exception行为与连接不良（这是专业的相机）一致。
将设备从交换机上拔下并重新插入，可将ping时间缩短到“正常”0.9ms。 过了一会儿，它又跳起来了。
我们无法识别任何与增加的ping时间开始一致的外部事件。 所有电缆都是cat6结构。
它闻起来像某种电子干扰，但奇怪的是，它工作一段时间，然后坏，但恢复正常，当电缆断开和重新连接。
任何想法将是非常受欢迎的。 谢谢！
（这是我的第一个问题，所以对于这个问题的任何新手道歉，

这似乎是一个networking布线问题。 电缆虽然质量很好，但是还是在其他一些电缆旁边传送，带有一些特别恶劣的干扰。 电缆被重新布线，问题消失了。
再次感谢您的帮助和关心。
