Recovering a Lost Enable Password
This section describes how to recover a lost enable password.
--------------------------------------------------------------------------------
Note You can recover a lost enable password, but not an enable secret password. This password is encrypted and must be replaced with a new enable secret password. See the \"Hot Tips\" section on Cisco Connection Online (CCO) for information on replacing enable secret passwords.
--------------------------------------------------------------------------------
Follow these steps to recover a lost enable password:
Step 1 Connect an ASCII terminal or a PC running a terminal-emulation program to the CONSOLE port on the rear panel of the router. Refer to the section \"Connecting the Console Port\" in the \"Installing the Router\" chapter.
Step 2 Configure the terminal to operate at 9600 baud, 8 data bits, no parity, and 1 stop bit.
Step 3 Reboot the router.
Step 4 At the user EXEC prompt (Router>), enter the show version command to display the existing configuration register value:
Router> show version
Step 5 Record the setting of the configuration register. It is usually 0x2102 or 0x102.
Step 6 Record the break setting.
Break enabled---bit 8 is set to 0.
Break disabled (default setting)---bit 8 is set to 1.
--------------------------------------------------------------------------------
Note To enable break, enter the config-register 0x01 EXEC command.
--------------------------------------------------------------------------------
Step 7 Do one of the following:
If break is enabled, go to Step 8.
If break is disabled, turn the router OFF, wait 5 seconds, and turn it ON again. Within 60 seconds, press the Break key. The terminal displays the ROM monitor prompt. Go to Step 9.
--------------------------------------------------------------------------------
Note Some terminal keyboards have a key labeled Break. If your keyboard does not have a Break key, refer to the documentation that came with the terminal for instructions on how to send a break.
--------------------------------------------------------------------------------
Step 8 Send a break. The terminal displays the following prompt:
rommon 2>
Step 9 Enter confreg 0x142 as follows to reset the configuration register:
rommon 2> confreg 0x142
Step 10 Initialize the router by entering the initialize command:
rommon 2> initialize
The router cycles its power, and the configuration register is set to 0x142. The router uses the boot ROM system image, indicated by the system configuration dialog:
--- System Configuration Dialog ---
Step 11 Enter no in response to the prompts until the following message is displayed:
Press RETURN to get started!
Step 12 Press Return. The following prompt appears:
Router>
Step 13 Enter the enable command to enter enable mode. Configuration changes can be made only in enable mode:
Router> enable
The prompt changes to the privileged EXEC prompt:
Router#
Step 14 Enter the show startup-config command to display the enable password in the configuration file:
Router# show startup-config
Step 15 Enter the configure terminal command to enter configuration mode:
Router# configure terminal
Step 16 Enter the configure register command to reset the configuration register to the original value that you recorded in Step 5.
Step 17 Press Ctrl-Z to exit configuration mode.
--------------------------------------------------------------------------------
Note To return to the configuration being used before recovering the lost enable password, do not save the configuration changes before rebooting the router.
--------------------------------------------------------------------------------
Step 18 Reboot the router, and enter the recovered password.
