二、在“rommon”下输入命令后,显示如下: rommon 1 > dev Devices in device table: id name flash: flash rommon 2 > dir flash: bad device name usage: dir <device> 由此可见路由器上的Flash上没有IOS或IOS损坏,得重新拷一个IOS到该系统。 三、进入“rommon”状态。(开启路由器的电源开关,并在30秒内按下键盘的Ctrl+break,中断路由器的正常启动以进入rom监视模式,屏幕上提示符如下: rommon 1> )在此状态下输入以下命令: 本文出自 51CTO.COM技术博客rommon 1 > xmodem flash 此时会显示“警告”信息,并问是不是要“继续”,你按“Y”。 然后,路由器一直等待从PC上接收该IOS映像文件。此时在超级终端软件中点击发送选项,选择存放在PC本地硬盘中的IOS映像文件,确定后即开始下载文件至路由器的flash rommon 1> 3) 键入xmodem命令: rommon 1>xmodem c2600-is-mz.120-8.bin(IOS映像文件名) 4) 然后,路由器一直等待从PC上接收该IOS映像文件,此时在超级终端软件中点击发送选项,选择存放在PC本地硬盘中的IOS映像文件,确定后即开始下载文件至路由器的flash 完成以后,会出现以下字幕: Do not start the sending program yet... device does not contain a valid magic number dir: cannot open device flash: WARNING: All existing data in flash will be lost!
