Chapter 3 Starting and Configuring

Replacing or Recovering a Lost Password

Step 7 Recover or replace the displayed passwords.

Step 8 Change the configuration register back to its original setting.

Note To recover a lost password if the Break function is disabled on the router, you must have physical access to the router.

Details of the Password Recovery Procedure

	Complete the following steps to recover or replace a lost enable, enable secret, or console login
	password:
Step 1	Attach an ASCII terminal to the console port on your router.
Step 2	Configure the terminal to operate at 9600 baud, 8 data bits, no parity, and 2 stop bits (9600 8N2).
Step 3	If you can log in to the router as a nonprivileged user, enter the show version command to display the
	existing configuration register value. Note the value for use later and proceed to Step 6. If you cannot
	log in to the router at all, go to the next step.
Step 4	Press the Break key or send a Break from the console terminal. If Break is enabled, the router enters the
	ROM monitor, indicated by the ROM monitor prompt (rommon1>). Proceed to Step 6. If Break is disabled,
	power cycle the router (turn the router off or unplug the power cord, and then restore power). Then
	proceed to Step 5.
Step 5	Within 60 seconds of restoring the power to the router, press the Break key or send a Break. This action
	causes the router to enter the ROM monitor and display the ROM monitor prompt (rommon1>).
Step 6	Set the configuration register using the configuration register utility; enter the confreg command at the
	ROM monitor prompt as follows:
	rommon1> confreg
Step 7	Answer yes to the enable “ignore system config info?” question, and note the current configuration
	register settings.
Step 8	Initialize the router by entering the reset command as follows:
	rommon2> reset
	The router initializes, the configuration register is set to 0x142, and the router boots the system image
	from Flash memory and enters the System Configuration Dialog prompt as follows:
	--- System Configuration Dialog --
Step 9	Enter no in response to the System Configuration Dialog prompts until the following message is
	displayed:
	Press RETURN to get started!
Step 10	Press Return. The user EXEC prompt is displayed as follows:
	Router>
Step 11	Enter the enable command to enter privileged EXEC mode. Then enter the show startup-config
	command to display the passwords in the configuration file as follows:
