路由器IOS升级方法总结(4)
采用这种方法时，由于使用console口来传送，速率为9600bps，需要时间较长。因此可修改console口速率利用xmodem命令实现快速升级IOS。具体方法如下：

注意：在按reset键前，需要修改串口速度（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，一定要这么做，否则会出现乱码！ 然后关闭这个超级终端，重新建立一个超级终端连接，重新启动系统后，出现ITPUB个人空间F7XR S0X\-^-rt0Jp9e,[0

此时，在超级终端的菜单上的“传送”---“发送文件”----选择IOS映像文件所在地以及选择使用“xmodem”协议，点击“发送”即可。等待10-20分钟左右就可升级完3-6M的IOS文件！待升级完成后，请记住修改回计算机串口与超级终端、路由器confreg下的xmodem等传输速率为9600bps。 ITPUB个人空间4i6s#g,?\2^ID{ a4L]3?W/~0ITPUB个人空间 N ZZFPdJK z

最好关掉电源后，重新启动。利用xmodem命令实现路由器IOS升级速度较慢，往往等上很长时间，为了快速升级，可以采用下列方法。导入论坛 引用链接 收藏 分享给好友 推荐到圈子 管理 举报
