Password recovery of the Cisco Routers
In order for one to understand these instructions you have to have prior knowledge of what a router is and its basic function.
1.Connect a computer to the router’s Console port using the Console cable that came with your router (it is usually flat and light blue). Use these Hyper terminal settings:
- 9600 baud rate
- No parity
- 8 data bits
- 1 stop bit
- No flow control
2. Turn the router off using the power switch and turn it back on.
3. Once text starts popping up on the screen, send the break command CTRL + B or CTRL +BREAK (sometimes it is CTRL +X). This will abort the boot and present you with a rommon 1> prompt
4. From the new prompt you need to change the configuration register using the following command: confreg 0×2142
5. If you are using an older model of router you may need to enter o/r 0×2142
6. Now you need to recycle the router with the reset command.
7. If you used the o/r command then reset the router with the I command
8. Once the router finishes restarting you will find that there are no passwords to deal with, so you can enter enabled.
9. Now, go into configuration mode with the config t command
10 .Once there enter the new password with the enable secret password
11. Now set the configuration register back to normal with this command: confreg 0×2102
