We're upgrading a VPN tunnel to IKEv2 between a Cisco FTD 2140 and a PA-850 running 9.1. What I've noticed is that the PA doesn't have an option for PRF on phase 1. Does the PA automatically make this the same as the integrity algorithm? Is there some other way to configure this?
Thank you.

FWIW, PRF was set to SHA256 on the Cisco FTD, and the tunnel negotiated with no problems. It was IKEv1 previously, so the transition went smoothly. Steve, thanks for your input.

From a simplicity perspective, the PRF is done internally within the PANW.
When creating the actual tunnel (IPSec tunnel menu item on the PANW), you can choose Manual Key, vs Auto Key
