sdwan interface down - recently upgraded to 10.1.6

L1 Bithead

Hi Team,


Until yesterday, we were running panos 9.1 and never faced any issues with the sdwan setup.

Within 24h after the upgrade to 10.1.6, all of a sudden the sdwan interfaces went down without an indication of any other issue/error.

No changes have been made to the configuration.


The sdwan is using 2 ipsec tunnels. Both were still online, no problem whatsoever.

Once I re-initiated the ike tunnel, the sdwan interface immediately went online.


Anyone who encountered the same behaviour?


Thank you in advance!

I can't say that I've seen or heard of anyone having issues with SD-WAN post 10.1 upgrade. There's a few known issues yet with SD-WAN with 10.1, but nothing that should be causing an issue like this. That being said, there was a large amount of changes regarding SD-WAN with PAN-OS 10 that wouldn't have been involved when you were running 9.1 that would come into play now that you're running 10.1. 

Just to make sure, are you running PAN-OS 10.1 now throughout the firewalls involved in your SD-WAN deployment, or do you still have a mixture of 9.1 and 10+? I'm kind of wondering how the SD-WAN Packet Duplication would be handled with older 9.1 firewalls in the fix yet. I can't think that would cause tunnel issues, but maybe?

We're currently running both 9.1 and 10.1, but in a few days we'll have the other site upgraded as well so basically I was also hoping this may solve our issues as well. I'll keep you posted!
