Session Keep Alive packet size

Good Afternoon Community!

I believe there is a minimum packet size for an application keep-alive packet for Palo Alto to register a session match. I am just having a hard time finding that documentation.

Does anyone know and could share or am I mistaken?

@DShofkom33x,

Actual keepalive packets are 64 bytes and really can't be any smaller than that.

Yeah that could be it, I understand that is more of a rfc spec but I could have sworn I ran into an issue before and TAC mentioned it was too small to trigger the session refresh so we had to do a App-override. I just cannot find the case or any supporting documentation.
