Appendix B Troubleshooting Initial Startup Problems
Replacing or Recovering a Lost Password
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.
Caution 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.
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.
This completes the steps for recovering or replacing a lost enable, enable secret, or console login
password.
