AttentionIf the below procedure doesn't work for you, contact vendor/website or IT company for help.


Cisco Router Secret Password recovery


Step 0. Plug console cable in.


Step 1. Power cycle the router.


Step 2. Send a "break" command to the router within the first 60 seconds after power cycle. Hit "Control /Break"


Step 3. From the ROM monitor prompt, set the configuration register value to 0x142. This causes the router to bypass the configuration contents stored in NVRAM upon next bootup. To do this, type:


> confreg 0x142


Step 4. Once the configuration register has been changed, initialize and reboot the router by typing the following:


> reset


The router will reboot itself.


Step 5. After the router boots up, you will be prompted if you want to enter the initial configuration dialog. Type: "n" for no. Note: If you accidentally enter the initial configuration dialog, abort by typing:


Step 6. Enter privileged EXEC mode by typing the enable command. No password will be required. The prompt will change to Router(boot)#.


Router> enable
Router#


Step 7. Load the original configuration back into the router.


Router# copy startup-config running-config


Note: If the router has originally been configured with a hostname, the prompt will now change to router_name#


Step 8. Set the new enable password.


Router# config term
Router(config)# enable secret


Step 9. Restore the configuration register and exit configuration mode.The configuration register must be reset so the router will properly boot using the configuration now stored in NVRAM.


Router(config)# config-reg 0x2102
Router(config)# end


Step 10. Save changes


Router# copy running-config startup-config


Step 11. Reload the router


Router# reload
