Cisco 2600 Series Router cannot remember PW need assistance!

Hi,

I have a 2600 Router series and I cannot remember the Password.  I have tried following web pages that state to use control Break on the boot up but its not working.   Anyone help on this so I can reset that pw and write erase my configuration file?

Here is my boot up.  I have tried hitting control break at the very beginning over and over and then again when at the cold boot it has not worked....

Brian.

What terminal program are you using to connect to the console?

If I remember rightly, Hyperterm had major issues with sending the break command to Cisco consoles, so it almost never worked. Try to download TerraTermPro and use that - it's got a menu option for sending "break", so you don't need to have a key combination.

Once you're in ROMMON mode, password recovery is easy.

Cheers

Password Recovery Procedure for the Cisco 2600 and 2800 Series Routers

http://www.cisco.com/en/US/products/hw/routers/ps259/products_password_recovery09186a0080094675.shtml

Never done it on this series, but the instructions say just use break, not control-break.

"Press Break on the terminal keyboard within 60 seconds of power up in order to put the router into ROMmon."

On section 4 there is more info if Break does not work.

Cisco 2600 Series Router cannot remember PW need assistance!

Hi,

I am using Windowss 7,  64 bit professional and for my terminal I am using tera term web 3.1  the application icon states ttermpro so kind of looked like the pro.

Anyway I found my own fix and it was very odd one I got it from the following web page:

http://www.routergeek.net/general/how-to-simulate-break-key-sequence-in-a-cisco-router/

To simulate the break key sequence, go through the following steps carefully:

1. Connect to the router with these terminal settings:

Baud rate: 1200

Parity: None

Data bits: 8

Stop bits: 1

Flow control: None

You will no longer see any output on your screen, and this is normal.

2. Power cycle (switch off and then on) the router and press the SPACEBAR for 10-15 seconds in order to generate a signal similar to the break sequence.

3. Disconnect your terminal, and reconnect with a 9600 baud rate. You enter the ROM Monitor mode.

those steps got me to Rommon 1 >

I think the normal password reset stuff will work now

I will give you the credit for the answer even though I found it, because you did bring up the Break in Terminal Pro and while I didnt test it that probably would have worked as well.  I will test that later to see if it works with my particular router.
