Chapter 3 Starting and Configuring the Router
Replacing or Recovering a Lost Password
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 1 stop bit (9600 8N1).
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 after waiting 30 seconds). 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:
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
Router# show startup-config
Step 12 Scan the configuration file display looking for the passwords (the enable passwords are usually near the beginning of the file, and the console login or user EXEC password is near the end). The passwords displayed look something like this:
enable secret 5 $1$ORPP$s9syZt4uKn3SnpuLDrhuei enable password 23skiddoo
