Active/Passive HA - Technical details: "How does it work?"

I manage our active/passive HA pair of PA-3050 firewalls currently running PAN-OS 7.0.8.  These were migrated a few years ago from PA-2020 devices that were put in by a previous network administration regime.

 

Our current network administration team is asking for technical details on how active/passive HA works on the PAN equipment, but I don't know the answer and can't find the information (other than how to configure it in PAN-OS).

 

Is there a good source of a technical description on how PAN's implemention of active/passive HA works, especially for PA-3050 devices?

Hi,

 

Did you try admin guide page 210?

 Config and operation the same across all models (a bit different on PA-200) but that is not your case. But just in case details below:
