21w6d: %PM-4-ERR_DISABLE: loopback error detected on Fa0/20, putting Fa0/20 in err-disable state 的信息,端口处于err-disabled状态,后来用errdisable recovery cause loopback恢复了。 由于err-disable的原因比较多,所以需要进一步确认,导致交换机接口出现err-disable的几个常见原因: 1. EtherChannel misc...
21w6d: %ETHCNTR-3-LOOP_BACK_DETECTED: Keepalive packet loop-back detected on FastEthernet0/20. 21w6d: %PM-4-ERR_DISABLE: loopback error detected on Fa0/20, putting Fa0/20 in err-disable state 以上信息就明确表⽰由于检测到第20端⼝出现了环路，所以将该端⼝置于了err-disa...

一会又发现另外交换机出现异常,登录查看也是err-disable state 由于环路问题而被置于错误状态的,所以就可以直接键入命令: 步骤一:拯救步骤1:查看日志/端口的状态 Switch# show inter g2/0/24 status *Sep 26 11:52:40.975: %PM-4-ERR_DISABLE: loopback error detected on Gi2/0/24, putting Gi2/0/24 ...
linkflap error detected on Fa0/17, putting Fa0/17 in err-disable state 所以,所在端口是因为link-flap才会造成频繁假死。link-flap是链路抖动,基本上是由于物理链路的问题导致,只要端口在10秒内出现了5次up/down,就会假死。那么,这种情况无非就是网口或网线本身的问题,还有一种可能是因为网卡的设置有问题(尤...
