Chapter 5 Replacing or Recovering Passwords
Password Recovery Procedure
Caution 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 the
router configuration.
Step 12 Enter the copy startup-config running-config command to load the startup configuration file into
running memory. This action allows you to modify or replace passwords in the configuration.
Router# copy startup-config running-config
Step 13 Enter the privileged EXEC command configure terminal to enter configuration mode:
Router# configure terminal
Step 14 Change all three passwords using the following commands:
Router(config)# enable secret
newpassword1
Router(config)# enable password
newpassword2
Router(config)# line con 0
Router(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 15 You must configure all interfaces to avoid having the system be administratively shut down:
Router(config)# interface fastethernet 0/0
Router(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 16 Use the config-register command to set the configuration register to the original value noted in Step 3
or Step 7, or to the factory default value 0x2102.
Router(config)# config-register 0x2102
Step 17 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.
Caution Do not execute the next step unless you have changed or replaced a password. If you skipped Step 12
through Step 15, go to Step 19. Failure to observe this caution causes you to erase the router
configuration file.
Step 18 Enter the copy running-config startup-config command to save the new configuration to NVRAM.
Step 19 Enter the reload command to reboot the router.
Step 20 Log in to the router using the new or recovered passwords.
