这个端口没有启动起来，出现这个问题的可能是连没有联接，或是联接错误。还有这个端口上面接的其它交换机之间的两个端口的协议不相同，所以就会出现FastEthernet0/5 is down
你把你的的这个端口协议改为默认协议，且这个端口级联的另一个交换机的相应端口的协议与此端口协议配置为相同协议就可以。
FastEthernet0/5 is down, line protocol is down (err-disabled)
物理接口down，协议down，手动开启物理接口之后出现什么问题？试过吗？
有什么问题啊，你网络不通啊还是什么啊？这些东西都是诊断的一些东西。翻译这个好麻烦啊，没有实际意义。
2950交换机接口默认是不用激活的啊！可能是网络环路自动down了吧！
晕，明明看到是（err-disable)了，是不是做了port-security啊？或者STP的BPDU-Guard？
