Enable password recovery through AUX port

I've got 2500 series router that accessible only through AUX port via direct connection using serial port on my PC. If I put the same cable to CONSOLE port I get nothing. I suspect that ACL was applied to CONSOLE port. Anyway, I lost enable password, so I can't access config mode to remove ACL. Standard Procedure to recover PW using break command during boot process throu CONSOLE port does nothing. What can I do to access this router?


Re: Enable password recovery through AUX port


Ideally u get the normal startup messages in the Console port only and u wont have the same kinda facitlity on in ur AUX port.

what i would suggest here at the first point is to change and try with different baud rates during normal startup.That mite do the trick...coz i have seen some cases where u got total difference in baud rate while in the normal mode and also different during startup mode.


Re: Enable password recovery through AUX port

In the past it was a common problem on the 2500,of the console port failing, you would see output from the router but could not input any data, is this your situation? of course if this is the case you cannot use the break key to get into rommon mode.

so you are stuffed!

Re: Enable password recovery through AUX port

I think it is not my situation-I can enter show commands through AUX port. Any other ideas?

Re: Enable password recovery through AUX port

please do a "sh ver " command and post it, this will tell you the state of the configuration register, then you can determine the speed the console port is set too etc.

And another problem-now AUX port is dead!!!

Re: Enable password recovery through AUX port

Ok, from the sh ver I see you do not have any flash memory installed and hence the router comes up in boot mode, which has restricted functionality, I don't know what you are using this router for, but really its not worth bothering about, be easier to get another one on eBay!
