Step 1 |
Power
reset the Router. |
Step 2 |
Within 60
seconds of the router reboot, press the
Ctrl+Break
keys. This puts the router in ROMMON mode. |
Step 3 |
The
router should boot to a router> prompt with no router name. |
Step 4 |
Type
o/r 0x42
at the router> prompt. This tells the router to boot from Flash
Memory without loading the configuration file. If you want to boot
from ROM instead, type o/r 0x41.
However, booting from ROM allows you to only view the encrypted
password or erase the configuration. You cannot change the password. |
Step 5 |
Type
i
at the router prompt. The router will now reboot, but ignore it’s
saved configuration (which contains the forgotten password). |
Step 6 |
When the
router boots up it will ask you if you want to configure the router.
Press Ctrl+C
to break out of the startup configuration. |
Step 7 |
Type
enable
at the router> prompt. This will put you in enable or Privileged
mode and the prompt will look like this: router# |
Step 8 |
Type
copy
startup-config running-config
(or copy start run) to copy the startup configuration into memory.
With the startup configuration in memory you can now change the
enable secret password. |
Step 9 |
At the
router# prompt type
config t
to go into global configuration mode. |
Step 10 |
At the
router(config)# prompt type
enable secret
new_password where
new_password is a new password. |
Step 11 |
You now
need to change your configuration register to tell the router to
boot up with the startup configuration file. Type
config-register
0x2102 and press
enter.
This tells the router to load the startup-config file in NVRAM when
it boots up. (use the number you saved from the show version
command) |
Step 12 |
Press
Ctrl+Z
to leave global configuration mode. |
Step 13 |
At the
router# prompt type
copy running-config
startup-config (or copy run
start). This will save your password change to NVRAM. |
Step 14 |
Type
reload
and press
enter to reboot the router. |
