Procedure 1
Complete these steps in order to recover your password:
1. Attach a terminal or PC with terminal emulation to the console port of the router and
set terminal settings to 9600 baud rate, No parity, 8 data bits, 1 stop bit, No flow
control.
The configuration register is usually set to 0x2102 or 0x102. If you can no longer
access the router you can safely assume that your configuration register is set to
0x2102.
2. Use the power switch in order to turn off the router, and then turn the router back on.
3. Press Break on the terminal keyboard within 60 seconds of power up in order to put
the router into ROMmon.

bypasses the startup configuration where the passwords are stored.
5. Type reset at the rommon 2> prompt.
The router reboots, but ignores the saved configuration.

procedure.
7. Type enable at the Router> prompt.

8. Type configure memory or copy startup-config running-config in order to copy
the nonvolatile RAM (NVRAM) into memory.
9. Type configure terminal.
The router(config)# prompt appears.
10. Type enable secret <password> in order to change the enable secret password.
For example:
router(config)#enable secret cisco
11. Issue the no shutdown command on every interface that you use.
12. Type write memory or copy running-config startup-config in order to commit the
changes.
Procedure 2

8. At the Router> prompt, type enable.
9. At the Router# prompt, enter the configure memory command, and press Enter in
order to copy the startup configuration to the running configuration.
