In-Depth Information
To move the hardware configuration register jumper, you might need to remove the
processor card from the router chassis. This is the case with the Route Processor (RP) card
in Cisco 7000 series routers. Refer to your hardware documentation for complete
instructions on removing and inserting the processor card. If you had to remove the
processor card, reinsert it before continuing.
Note
Power up the router.
The router will boot but will ignore the contents of NVRAM and enter the Setup routine.
Step 3
Answer
no
to all the setup questions.
The Router prompt appears.
Step 4
Enter the
enable
exec command.
Step 5
Enter the
show configuration
privileged exec command to see whether the password is in clear text (is
not encrypted) or if it is encrypted.
If the password is in clear text, go to Step 10. If the password is encrypted, continue with Step 7.
Step 6
If the password is encrypted, enter the
configure memory
privileged exec command. This writes the
stored configuration into running memory.
Step 7
Enter the
configure terminal privileged exec
command to enter router configuration mode.
Step 8
If you have lost the enable password, use the
enable-password global
configuration command to
configure a new password.
If you have lost the login password, configure the console line with a new login password using the
login
and
password
line configuration commands. Press CTRL-Z to exit configuration mode. Proceed to
Step 11.
