用xmodem重新快速安装IOS

陈杰

<P>先打开超级终端，进入rommon 模式（Ctrl+Break组合键），键入confreg, 如下： <BR>~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ <BR>rommon 1 &gt; confreg 回车 </P><P>Configuration Summary <BR>enabled are: <BR>load rom after netboot fails <BR>console baud: 9600 <BR>boot: image specified by the boot system commands <BR>or default to: cisco2-C2600 </P><P>do you wish to change the configuration? y/n [n]: y (选择 yes) <BR>enable "diagnostic mode"? y/n [n]: n (选择 no) <BR>enable "use net in IP bcast address"? y/n [n]: n (选择 no) <BR>disable "load rom after netboot fails"? y/n [n]: n (选择 no) <BR>enable "use all zero broadcast"? y/n [n]: n (选择 no) <BR>enable "break/abort has effect"? y/n [n]: n (选择 no) <BR>enable "ignore system config info"? y/n [n]: n (选择 no) <BR>change console baud rate? y/n [n]: y (选择 yes) <BR>enter rate: 0 = 9600, 1 = 4800, 2 = 1200, 3 = 2400 <BR>4 = 19200, 5 = 38400, 6 = 57600, 7 = 115200 [0]: 7 (选择 7,用最大的115200速率的xmodem传输) <BR>change the boot characteristics? y/n [n]: n (选择 no) </P><P><BR>Configuration Summary <BR>enabled are: <BR>load rom after netboot fails <BR>console baud: 115200 <BR>boot: image specified by the boot system commands <BR>or default to: cisco2-C2600 </P><P>do you wish to change the configuration? y/n [n]: n (选择 no) <BR>You must reset or power cycle for new config to take effect </P><P>rommon 2 &gt; reset 回车 <BR>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 </P><P>rommon 1&gt; 提示符 <BR>然后,输入 <BR>rommon 1&gt; xmodem -r <BR>Do not start the sending program yet... </P><P>Invoke this application only for disaster recovery. <BR>Do you wish to continue? y/n [n]: y (选择 yes) <BR>Ready to receive file ... </P><P>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 </P><P>然后等待10-20分钟左右就把3-6M的IOS灌进去了！ </P><P>~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ <BR>（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） </P><P>（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） </P><P><BR>Router&gt;en 进入新IOS的特权模式 </P><P>Router#reload 重启系统 </P><P>Proceed with reload?

<P>这个方法倒没用过</P><P>上次试过给2900灌IOS。。。没设置用了40分钟</P><P>下次试试这个方法</P><P>&nbsp; <IMG src="http://www.spoto.net/bbs/images/Emotions/8.gif"><IMG src="http://www.spoto.net/bbs/images/Emotions/8.gif"><IMG src="http://www.spoto.net/bbs/images/Emotions/8.gif"><IMG src="http://www.spoto.net/bbs/images/Emotions/8.gif"><IMG src="http://www.spoto.net/bbs/images/Emotions/8.gif">可怜的2900又要当实验品了（同情ING）</P>

<P>很有意思呀。</P><P>陈杰的资料很有价值，大家可以看看。</P><P>继续努力。。。不过要保证机器的安全<IMG src="http://www.spoto.net/bbs/images/Emotions/2.gif"></P>

陈杰

<P>呵呵~~谢谢</P><P>一定会在保证机子的安全之下实行的</P>

可以多给你们些机会嘛，说不定还能发现什么新大陆哦，呵呵<IMG src="http://www.spoto.net/bbs/images/Emotions/12.gif"><IMG src="http://www.spoto.net/bbs/images/Emotions/12.gif"><IMG src="http://www.spoto.net/bbs/images/Emotions/12.gif"><IMG src="http://www.spoto.net/bbs/images/Emotions/12.gif">
