The enable secret password is encrypted and cannot be recovered; it must be replaced. The enable and console login
passwords may be encrypted or clear text. Proceed to the next step to replace an enable secret, console login, or enable
password. If there is no enable secret password, note the enable and console login passwords, if they are not encrypted,
and proceed to Step 17.
Do not execute the next step unless you have determined you must change or replace the enable, enable secret,
or console login passwords. Failure to follow the steps as shown might cause you to erase your router
configuration.
Caution
Step 13
Enter the configure memory command to load the startup configuration file into running memory. This action allows
you to modify or replace passwords in the configuration.
Router# configure memory
Step 14
Enter the privileged EXEC configure terminal command to enter configuration mode:
Hostname# configure terminal
Step 15
Change all three passwords using the following commands:
Hostname(config)# enable secret newpassword1
Hostname(config)# enable password newpassword2
Hostname(config)# line con 0
Hostname(config-line)# password newpassword3
Change only the passwords necessary for your configuration. You can remove individual passwords by using the no
form of the above commands. For example, entering the no enable secret command removes the enable secret password.
Step 16
You must configure all interfaces to be not administratively shut down as follows:
Hostname(config)# interface gigabitethernet 0/0
Hostname(config-int)# no shutdown
Enter the equivalent commands for all interfaces that were originally configured. If you omit this step, all interfaces are
administratively shut down and unavailable when the router is restarted.
Step 17
Use the config-register command to set the configuration register to the original value noted in Step 3 or Step 8, or to
the factory default value 0x2102 as follows:
Hostname(config)# config-register 0x2102
Step 18
Press Ctrl-Z (hold down the Control key while you press Z) or enter end to exit configuration mode and return to the
EXEC command interpreter.
Do not execute the next step unless you have changed or replaced a password. If you skipped Step 13 through
Step 16, skip to Step 20. Failure to observe this caution causes you to erase your router configuration file.
Caution
Step 19
Enter the copy running-config startup-config command to save the new configuration to NVRAM.
Step 20
Enter the reload command to reboot the router.
Step 21
Log in to the router with the new or recovered passwords.
