我这里有一台CISCO2901/K9路由器,因为忘记密码了,所以想进入rommon重置配置,但断电重启后开始不停地按Ctrl键+pause,但怎么也进入不了rommon,依旧正常启动了。请问这是怎么回事?还有其他方法吗?谢谢!

中断启动是用Ctrl+Break键进行操作,可以尝试找个标准键盘操作一下。或者使用windows屏幕键盘(运行输入osk打开屏幕键盘)辅助进行按键,组合按键Ctrl+ScrLK

我用虚拟键盘Ctrl+ScrLK没有任何反应

用外接键盘我用虚拟键盘Ctrl+pause/break也没有任何反应

发一下你CRT serial-com3的设置,

另外尝试开机长按空格键试试

怀疑中断的信号没正常送进设备

要在加载IOS之前,输入Crtl+Break,进入ROMMON模式,

笔记本电脑为了控制整体尺寸,键盘键位都有不同成度的精简,Break键在很多笔记本电脑的键盘上是不存在的,

简单点的办法是 通过USB口外接标准键盘,或是通过虚拟键盘来输入正确的中断命令;

 

一开电源,我就不停地按组合件,用虚拟键盘的Crtl+pause、Ctrl+ScrLK,外接键盘的Ctrl+pause/break都没有任何反应,依旧是正常启动

參考下列文檔,原廠的建議是Cisco 2900 router先關機後,移除router上面的Compack flash card,然後重新開機就會進入ROMMON mode.https://www.cisco.com/c/en/us/support/docs/routers/2800-series-integrated-services-routers/112033-c2900-password-recovery-00.html
