How to do factory reset or restore to a ASA5516-X firewall

How to do factory default or reset ASA5516 -X ??

It's a new firewall. And I had just just for practice I applied /created following commands.

Note: I did't apply any license key in it and configured following commands. And unfortunately I got locked. Notable to access cli as well as through GUI. Any way to set factory default??? If any help much appreciated

hostname ASA1

crypto key generate RSA label cciekey modulus 1024

crypto ca trustpoint ccietrust

enrollment self

subject-name CN=ASA1 Of=cisco.com

Then I powered off the device. Thought whatever I have I configured it should erase.

You do not need factory reset.

Do password recovery:

Hello,

Leon is right. You need to do a password recovery if you can't get into the ASA via CLI or GUi. After you do get in, if you still want to do a factory reset, then you can do the following:

1. "write erase"

This will erase the startup config.

2. "reload noconfirm"

This will reload the device without asking you if you want to save the configuration. You could also just do a "reload" and then say "no" when asked to save the configuration.

The device will load up with the default configuration and ask you if you want to use the menu based configuration system or not.

Thanks!
