A Hut8 Networking Techtorial: Cisco Adaptive Security Appliance (ASA) OS File Management
In Module 02 of the ASA Basic Configuration Techtorial we take a look at the different methods of getting the ASA OS image on to your ASA. We cover where you would go to download the ASA OS (you need an entitlement!), why it is important to read the release notes, the recommended ASA OS for the different ASA5505 hardware versions, how to load images from ROMMON via TFTP, how to upgrade/TFTP an image if your ASA is operational, and then close out Module 02 by showing how to hard-code the ASA to boot to a specific image when you have more than one (1) image present on the ASA. Enjoy!
