Recovering a Lost Password

To recover a lost enable or lost enable-secret password:

1.Change the Configuration Register

2.Reset the Router

3.Reset the Password and Save Your Changes (for lost enable secret passwords only)

4.Reset the Configuration Register Value

Note Recovering a lost password is only possible when you are connected to the router through the console port. These procedures cannot be performed through a Telnet session.

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.

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

Step 3 At the privileged EXEC prompt (router_name #), enter the show version command to display the existing configuration register value (shown in bold at the bottom of this output example):
