Thanks BPry, appreciate your comment and time spent answering question. The 'power off' upgrade process was less likely applicable for my case as i mentioned in the original post that during my previous jobs i had successfully performed PAN OS upgrade, losing 1,2 pings which makes me believe i did follow the upgrade process properly and not just powering off the firewall. I would suspect that powering off the firewall will cause more lost pings. I am leaning more towards LACP settings at this moment. I am strong believer that this community is a great place to get answer, sharing ideas, best practice, tips and trick and that everyone's time is valuable, including mine. Being in this line of work for quite some time, i do understand the importance of right information so i am trying to put as much useful details in the original post as possible which should allow people willing to assist to be pointed into right direction. If there is not enough information, it is much easier to ask question instead making assumptions. I think everyone will benefit from this..

Thanks Sec101, appreciate your comment; i dont think the issue is STP since firewalls are conencted directly; no switch in between.

Appreciate your concern; i have been working with PAN for a quite some time and never had an issue with OS upgrade but that was not my question...

During the last PAN OS upgrade we had to failover between two firewalls in HA configuration. The failover time takes unusually amount of time during which the Internet access was unavailable. It took approximately 10-15 lost pings (to internet host) for passive to become an active. We had opened a case with PAN support and our zoom meeting was dropping, it was reconnecting after about 15 sec automatically. In one of my previous jobs the failover was taking very quickly, i would lost 1 or 2 pings 8.8.8.8.. Our HA setup is like this: HA1 - over aux-1 HA2 - over eth1/10 Mode is active-passive/the config sync is enabled/passive link state is auto/preemptive is not setup/LACP-LLDP is not configured/Link and path monitorings are enabled/ Wondering if someone had simmilar experience and what was the solution to speed up the failover.
