regarding the title above, i facing some problem before key-in format system command. once type "router> enable", then 2nd row it prompt key-in password which i set before, i cannot type any character at telnet service. if password does not set, the character "router>", change to "router#" if type "router> enable".

Hi,

What is the problem? You can't go to enable mode? the format command is not working? be more specific please.

i mean after i type "router>enable", then it prompt password to continue which i set before. but now i cannot proceed because when i type any key at keyboard, there is no any character come out for password. then i want format the ios software. but cannot due i still at "router>" command.

so you can type enable then when prompted for password you can't type anything?

Or it won't take the password you set to enter privileged mode?

[wangkiantjun]

the 1st statement which state "can type enable then when prompted for password you can't type anything."

this is the problem i face now.

you mentioned doing this via telnet. how about trying to enter your enable password/secret directly via console? if that doesn't work you need to do a password recovery procedure.

[cadet alain]

Have you tried to reload it? Have you tried different softwares to telnet to your router?

[wangkiantjun]

i unable to type any key on the keyboard once prompt for password. what shoud you said i think it should be secret directly via console.

but how to recover the password process? since i only manage router global configuration only.

password recovery :

This will work for your router. Once done you should be able to get into the router and reload the new IOS as well.

Note: You need to be connected via console as well.

Pssst.  Have you seen my comment?

Password recovery on an 870 ISR?  Easy.  Look at the back.  See there's a "reset" button?

[wangkiantjun]

yes. it works. i want ask after i reset it, does the existing configuration also
delete too? if yes, so i need to re-configure again the configuration setting from the beginning?

[Leo Laohoo]

Yes it will erase existing config and set the router into factory default.
