To recover a lost password, follow these steps:
Step 1 Attach an ASCII terminal to the router console port, which is located on the rear panel.
Step 2 Configure the terminal to operate at 9600 baud, 8 data bits, no parity, 2 stop bits (or to whatever settings
the router is set).
Step 3 Enter the show version command to display the existing configuration register value. Note this value for
later use in
If the Break function is disabled, power cycle the router. (To power cycle, turn off the router, wait 5

Break to the bootstrap program prompt.
Change the configuration register to ignore NVRAM.
Enter privileged level in the system EXEC.
Enter the show startup-configuration command to display the enable password.
Change the configuration register value back to its original setting. If the enable password is
encrypted, the following procedure does not work for password recovery and you must reconfigure
the router using the displayed configuration (shown in Step 11), instead of rebooting it.
