http2 is a new protocol decoder in the 9.0.x version of the PANOS.
Is this message seen on the Panorama, or on a FW that receives its config from the Panorama.
If you go under your AntiVirus Profile, how many protocol decoders do you see?
Thanks for the quick response. So Panorama 9.x does not fully support 8.1.x firewalls? If it does, then it should be smart enough to know that a 8.1.x firewall doesn't support http/2 and not produce a red warning message. PA5060s cannot run 9.x
If one is using Panorama to manage several firewalls (which is by design), and most are at 9.x but a couple have to stay at 8.1.x (ex. PA5060), then having Panorama at 9.x would make sense for the majority of the other firewalls. I feel this is a UI defect as a warning shouldn't be produced when pushing from 9.x Panorama to 8.1.x PAN OS firewall(s).
