In this short guide I wanted to walk through the steps to do a factory reset for the Cisco Firepower 2100 series. When doing these resets all configuration and the administrative password are removed, as well as the FTD (Firepower Threat Defense) app-instance. When the unit starts to boot it will reinstall the FTD app-instance to default configuration.
You have the FMC installed and connect to FTD device with configuration deployed but for what ever reason there is a problem and you need to enter the CLI on the Firepower device to troubleshoot the equipment and although you can’t configure anything you can do show and debug commands to troubleshoot via the CLI.

Cisco is actively pushing their Firepower Threat Defense software with the new Firepower 2100 units on their way this summer in effort to eventually replace the ASA5525-X, ASA5545-X and ASA5555-X platforms.

This gets difficult especially if you want to test things out because not everyone has Cisco Firepower lying around unused. How are you supposed to test and learn the depths of this product?

I got my hands on some Cisco Firepower 4100 units and after playing around with them I wanted to reset them to factory settings, essentially erase the “startup-config” on the FXOS.

(Edit: 7-21-17) After Gabriele made this comment it looks like you can. You also can follow the password recovery on this post which will also erases the configuration. Continue reading
