What does FBO stand for

We are troubleshooting something with TAC wherein they asked us to set the FBO to "Software".

What, exactly, is an FBO? I cannot find any references thereto in the docs besides the CLI reference, and that tells me nothing.

@kiwi @JayGolf I have been led to believe that you're the experts on this (see https://live.paloaltonetworks.com/t5/general-articles/tips-amp-tricks-flow-basic-debugging/ta-p/545999) , any insight would be appreciated.

Hi @dan_urson ,

Setting FBO to "software" allows the firewall to attempt SSL decryption using software processing instead of hardware, providing a secondary layer of processing for encrypted traffic. However, it can impact performance, so it should be configured with consideration of the firewall's capacity.

Using the "fbo show" command as seen in the example below allows you to see which operations are set to hardware/software processing.

You can set specific ones to hardware/software or all of them at the same time:

> debug dataplane fbo show DP s1dp0: offload timeout: 200 ms rsa-sign = software rsa-verify = hardware ecdsa-sign = software ecdsa-verify = hardware ecdhe-key-generate = software ecdhe-key-compute = hardware > debug dataplane fbo set > all Use hardware/software for all RSA and EC operations > ecdhe-key-compute Use hardware/software for ECDHE key compute > ecdhe-key-generate Use hardware/software for ECDHE key generate > ecdsa-sign Use hardware/software for ECDSA sign > ecdsa-verify Use hardware/software for ECDSA verify > rsa-sign Use hardware/software for RSA sign > rsa-verify Use hardware/software for RSA verify #To set all to sofware : > debug dataplane fbo set all software

Hope this helps,

-Kim.
