rommon 2 > reset 回車注意:在按reset鍵前,需要修改串口速度(我的電腦——端口屬性——串口速度調(diào)為115200),然后再修改超級終端里設(shè)置速率為115200,記住,一定要這么做,否則會出現(xiàn)亂碼! 然后關(guān)閉這個超級終端,重新建立一個超級終端連接,重新啟動路由器后,出現(xiàn)界面。
rommon 1> 提示符然后,輸入
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 (選擇 yes)
Ready to receive file ……
此時,在超級終端的菜單上的“傳送”——“發(fā)送文件”——選擇IOS映像文件所在地以及選擇使用“xmodem”協(xié)議,點(diǎn)擊“發(fā)送”即可。待升級完成后,請記住修改回計(jì)算機(jī)串口與超級終端、路由器confreg下的xmodem等傳輸速率為 9600bps.
方法如下:
