并且有人反映8-24端口不能用   请大家帮我吧  没有经验很痛苦  不知道怎么排错 也不知道如何排除故障

遇到这样的问题 应该如何去排查呢？那位高手 写个流程 谢谢

部分端口频繁震荡，建议先检查一下端口是否存在物理故障，

把你的拓扑图发送上来，还有配置命令

最简单的方法就是把线全部拔了 一个一个插 慢慢观察。 或者你看上面的配置显示28口频繁DOWN和UP，你先看看28口连的是什么设备

顶一下吧，无图无真相，大家都这么说，我帮你顶顶

TOP受限制的

设备在县公司里 今天有人专门过去看了 可惜不是我 据说是端口坏掉了 准备换台新的3050 悲剧啊 故障就这样解决了 我还没理清呢？你们是如何判断的啊 介绍下嘛

看SNMP信息、LOG信息，
不外乎，端口坏了、有环路，端口不停的UP和DOWN、STP不停的切换。。
地址冲突一类的。。
