使用 CISCO系列交换机或路由器的用户在工作中经常遇到错误信息提示“errdisable”;当你查看端口状态(showinterfacestatus)时,正常情况下你会看到 status为 connected或 notconnect,有时为disable,偶尔会成为 err-disabled。那么,在 CISCO系列交换设备中,什么是 errdisable呢?er-rdisable同 errdisabled、err-disabled,就...
通常情况下,如果交换机运转正常,其中端口一项显示为启用(enable)状态.但是如果交换机的软件(CISCO IOS/CatOS)检测到端口的一些错误,端口将随即被关闭.也就是说,当交换机的操作系统检测到交换机端口发生些错误事件的时候,交换机将自动关闭该端口. 当端口处于err-disabled状态,将没有任何流量从该端口被转发出去,也将不...

dhcp-rate-limit Enabled unicast-flood Enabled 从列表中,我们可以看出常见的原因有udld,bpduguard,link-flap以及loopback等。 具体由什么原因导致当前接口err-disable可以由show interface status err-disable来查看。 在接口模式下采用shutdown,no shutdown进行手动的激活。
