Router 1841 恢復預設值

 

新版的Router居然改了預設登入模式，預設帳號Cisco登入過後就失效了，我又臭屁3分鐘完成設定完後習慣就Reload，cisco帳號就無法登入，就變成都無法登入Console了，只能想辦法重設…

重設方法如下:

Start a terminal session with the router via the Console port (telnet will not work for this). Physically reload the router, and from the console repeatedly hit the "Break" key, normally on the upper right hand side of the keyboard.

-You should now be in ROMMON mode. Type "confreg 0x2142" without quotes and hit Enter. Now type "reset" without quotes and hit Enter.

-Allow the router to restart, and hit "n" followed by Enter to stop the startup wizard.

-Type the following command sequence:

enable
conf t
config-register 0x2102
exit
write erase
<Enter key>
reload

The router will now boot normally, with a factory default configuration, even if you did not know any of the password(s) securing the router.
