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

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
