Warning in panorama "app not found"

[BigPalo]

We are having a warning when we push in panorama:

We have check the apps&threats version and everything is OK. Panorama version is 9.0.4. It could be a cosmetic issue?

[S.Cantwell]

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?

[BigPalo]

Yes, you are right. Panorama is in version 9.0.4, and FWs in 8.1.10.

Is there any way to delete this warning in Panorama? 

[S.Cantwell · Accepted solution]

Not that I am aware of... short of recommending that you upgrade FWs (or downgrade Panorama)

[palotalk]

I can confirm Panorama 9.0.5 push to 8.1.12 (pa5060) still has this warning.  Will 9.0.6 resolve this (if/when released)?  Does 9.1.0 resolve this?

Any one from Palo Alto wish to comment?

As soon as you upgrade the firewall to 9.0.x or downgrade panorama to 8.1.x the warning will disappear.

If you only upgrade panorama to 9.0.6 or even 9.1.0 but the firewall stays on 8.1.x this won't change anything.

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).

What did you choose as option in the AV profile(/s) that is(/are) pushed to the 8.1 firewall for http2?

PS: I do not work for paloalto

[palotalk]

Thanks for the response.  It is set to allow for http2.

[Remo]

Did you try to set it to default in the profiles that are applied to your 8.1 firewall?

[palotalk]

Hi, yes, it results in the same warning.

[Remo]

Ok, last try until I give up 😛

Did this warning start right then when you upgraded your panorama to 9.0.x? What about deleting the action in that profile (via cli on panorama), did you try this? The goal is to have a profile where maybe the http2 is shown in the web UI but not actually in the config that is applied to the firewall.

PS: I am with you that panorama should detect that as this warnkng is totally useless in this situation.

[palotalk]

Hi, thanks for the help and support.  No I didn't try that.  I'll probably put in a support request.  Obviously others have this issue, so maybe they will have a solution?

[Remo]

Give it a short try 😉

Maybe then you get rid of this warning as the other possibility is probably waiting for a fix ... and this could take some time - or you live with the warning...
