It's (very loosely) kind of like a hypervisor in that it controls the hardware and the FTD or ASA is a logical device that runs over the abstraction layer provided by FXOS.Ī Firepower appliance can run ASA software but in that case you don't get any of the IPS or NGFW capability. On the 11 series with FTD it's embedded and it's not generally necessary to interact with it.

On the higher end models (41 series) it's a separate OS that you interact with via the cli or Firepower Chassis Manager. Any assistance you can provide on how all these software's fit together and how to go about accessing them on the device would be greatly appreciated!įirepower appliances all run FXOS. I only have experience with the ASA 5545x running the Firepower module, which made the deployment much more straightforward. Do these devices run the ASA software? If not, how do you configure classic firewall rules on the device? is the ASA software accessed in a different way than the Firepower software? From what I understand FXOS is like a hypervisor software that allows FTD software and ASA software to run on these devices? Do the 2140's run FXOS? I am unable to see if they are at the moment. I had a few questions about these devices: The appliances seem to have the Firepower software already installed running version 6.2.2 (Build 81)and are currently imported into an FMC.

We would like to migrate away from the ASA's onto the Firepower appliances but I am not sure where to start. We are still currently running off of ASA5545X. Our organization has 4x 2140 Firepower appliances, however they are not currently operational in the network. I am new to the Firepower appliances and had some questions.
