    概要:先打开超级终端,进入rommon 模式(Ctrl+Break组合键),键入confreg, 如下: rommon 1 > confreg 回车 Configuration Summary enabled are: load rom after netboot fails console baud: 9600 boot: image specified by the boot system commands or default to: cisco2-C2600 do you wish to change the configuration? y/n [n]: y (选择 yes) enable "diagnostic mode"? y/n [n]: n (选择 no) enable "use net in IP bcast address"? y/n [n]: n (选择 no) disable "load rom after netboot fail

    先打开超级终端,进入rommon 模式(Ctrl+Break组合键),键入confreg, 如下:

      rommon 1 > confreg 回车

      Configuration Summary

      enabled are:

      load rom after netboot fails

      console baud: 9600

      boot: image specified by the boot system commands

      or default to: cisco2-C2600

      do you wish to change the configuration? y/n [n]: y (选择 yes)

      enable "diagnostic mode"? y/n [n]: n (选择 no)

      enable "use net in IP bcast address"? y/n [n]: n (选择 no)

      disable "load rom after netboot fails"? y/n [n]: n (选择 no)

      enable "use all zero broadcast"? y/n [n]: n (选择 no)

      enable "break/abort has effect"? y/n [n]: n (选择 no)

      enable "ignore system config info"? y/n [n]: n (选择 no)

      change console baud rate? y/n [n]: y (选择 yes)

      enter rate: 0 = 9600, 1 = 4800, 2 = 1200, 3 = 2400

      4 = 19200, 5 = 38400, 6 = 57600, 7 = 115200 [0]: 7 (选择 7,用最大的115200速率的xmodem传输)

      change the boot characteristics? y/n [n]: n (选择 no)

      Configuration Summary

      enabled are:

      load rom after netboot fails

      console baud: 115200

      boot: image specified by the boot system commands

      or default to: cisco2-C2600

      do you wish to change the configuration? y/n [n]: n (选择 no)

      You must reset or power cycle for new config to take effect

      rommon 2 > reset 回车

      注意:在此时键入 reset键之前,开始定义串口速度(我的电脑---端口属性----串口速度调为115200),然后再修改超级终端里设置速率为115200,记住,一定这么做!否则出现乱码!然后关闭这个超级终端,重新建立一个超级终端连接,(期间系统重新启动)启动后,出现

      rommon 1> 提示符

      然后,输入

      rommon 1> xmodem -r

      Do not start the sending program yet...

      Invoke this application only for disaster recovery.

      Do you wish to continue? y/n [n]: y (选择 yes)

      Ready to receive file ...

      此时,在超级终端的菜单上的“传送”---“发送文件”----选择IOS镜像文件所在地以及选择使用“xmodem”协议,点击“发送”即可

      然后等待10-20分钟左右就把3-6M的IOS灌进去了!

      ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

      (修改回计算机串口与超级终端、路由器confreg下的xmodem等9600的传输速率)

      (videre注:实际用的时候,我发现这个命令总是改不成功,后来发现在line con 0下面有了一个speed 115200,所以即使改register成功,启动以后router又执行speed 115200,还是不行,所以如果有这个问题,记得把这个语句no掉)

      Router>en 进入新IOS的特权模式
