Chapter 5 Replacing or Recovering Passwords

Password Recovery Procedure

Step 2 Configure the terminal to operate at 9600 baud, 8 data bits, no parity, and 1 stop bit.

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, then go 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 signal from the console terminal.

If break is enabled, the router enters the ROM monitor, indicated by the ROM monitor prompt (rommon>). Go to Step 6.

If break is disabled, power cycle the router (turn off the router or unplug the power cord, and then restore power). Then go to Step 5.

Step 5 Within 60 seconds of restoring the power to the router, press the break key or send a break signal. This action causes the router to enter the ROM monitor and display the ROM monitor prompt (rommon>).

Step 6 Set the configuration register using the configuration register utility. Enter the confreg command at the ROM monitor prompt as follows:

rommon> confreg

Answer yes to the enable “ignore system config info?” Press the return key at all other prompts to accept the existing value.

Step 7 Reboot the router by entering the reset command:

rommon> 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 (setup):

--- System Configuration Dialog --

Step 8 Enter no in response to the system configuration dialog prompts until the following message appears:

Press RETURN to get started!

Step 9 Press Return. The user EXEC prompt appears:

Router>

Step 10 Enter the enable command to enter privileged EXEC mode. Then enter the show startup-configcommand to display the passwords in the configuration file as follows:

Router# show startup-config

Step 11 Scan the configuration file display, looking for the passwords (the enable passwords are usually located near the beginning of the file, and the console login or user EXEC password is near the end). The passwords displayed appear similar to the following:

enable secret 5 $1$ORPP$s9syZt4uKn3SnpuLDrhuei enable password 23skiddoo

.

.

line con 0

password onramp

The enable secret password is encrypted and cannot be recovered; it must be replaced. Go 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 the enable and console login passwords are not encrypted, go to Step 16.
