How to Factory Reset a 3850 Switch Without Password?

Factory resetting a 3850 switch without the password can be tricky but possible in certain scenarios. If you've forgotten the password or acquired a used switch without the login credentials, there are steps you can take to reset it to factory settings.

One method is to connect to the switch through the console port using a console cable. Upon booting up, you can interrupt the boot process by pressing Ctrl+C to access ROMMON mode. From here, you can initiate the password recovery process which involves changing the configuration register value, reloading the switch, and then resetting the password.

Another approach is to perform a password recovery through the front panel button. By holding down the mode button located on the front panel of the switch while powering it on, you can initiate the password recovery process.

It's important to note that these methods should only be used on switches that you own or have the permission to reset. Unauthorized access to devices is illegal and unethical.
