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 RP card in Cisco
7000 series routers. Consult 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 ROM monitor (>) prompt appears. Step 3

Enter b (bootstrap) at the (>) prompt. Step 4

Press the Return key until the Test-System prompt appears. Step 5

Enter privileged mode by issuing the enable exec command.

Step 6

Enter the show configuration privileged exec command to see whether the password is clear-text (is not
encrypted) or is encrypted.
If the password is clear-text, go to Step 12.
If the password is encrypted, continue with Step 8.

Step 7

If the password is encrypted, enter the configure memory privileged exec command.
This writes the stored configuration into running memory.

Step 8

Enter the configure terminal privileged exec command to enter router configuration mode. Step 9

If you have lost the enable password, use the enable-password global configuration command to
configure a new password, and press CTRL-Z to exit configuration mode.
If you have lost the login password, configure the console line with a new password using the login and
password line configuration commands. Press CTRL-Z to exit configuration mode.
Syntax:
To enable password checking at login, use the login line configuration command:
login [ local | tacacs ]
Syntax description:
• local —(Optional) Selects local password checking. Authentication is based on the username
specified with the username global configuration command.
• tacacs —(Optional) Selects the TACACS-style user ID and password-checking mechanism.
Examples:
The following example sets the password letmein on virtual terminal line 4:
Syntax:
To specify a password on a line, use the password line configuration command:
password password
Syntax description:

Step 10

password —Character string that specifies the line password. The first character cannot be a number.
The string can contain any alphanumeric characters, including spaces, up to 80 characters. You
cannot specify the password in the format number-space-anything. The space after the number
causes problems. For example, hello 21 is a legal password, but 21 hello is not. The password
checking is case-sensitive. For example, the password Secret is different from the password secret .
