Recover one-time password to ISR G2 2911

Hello, I've got a problem, I didn't change the one-time password in ISR 2911 and I can't access the CLI or the ROMMON mode, so I'd be very grateful if anyone can help me.

Thanks.

Hi Jaime,

I am not sure If I understand what you mean by one time password.  You can use the same password you have been using on the console. It does not expire until you change it.

Try "Cisco/Cisco".

Hi Jaime.

I have the same problem. Please let me know if you came right on this. I have been googling the whole day and cannot find anything. The usual cisco breaking procedure does not work on these 2911s. I have tried various terminal emulation programs but cannot access rommon mode with the break process.

Please help ...

Hi,

2900 series router you should wait till it finishes decompression of the image file then press the break sequence.

Please let me know if this was helpful.

@podhillo. Thanks very much. That worked. This must be new, because even cisco (on the website) advises ppl to press the break within 60 seconds of power up and nothing about 60 seconds after the image have decompressed (follow link to point 4).

@leolaohoo. Thanks for the reply. I am sure that will work as well. I did not try it, but did it in the passed, but forgot about that option. Thanks for reminding me.

Ok, if you can't use the Break Sequence, pop out the out the compact flash and boot the router.

Yes, the CF, on the lower left hand corner of the back of the router can be ejected.  I've tried it and it works!
