Hi @HermanEdwards, the best way to validate anything with 100% conclusive proof is to export/backup the XML config file and look at it in a text editor/viewer. Here you will be able to see the configuration elements.
Certainly in recent PAN-OS releases (per screenshot below for Panorama, where I have collapsed a lot of the lines of XML config), a large amount of config lives under the devices/entry[@name='localhost.localdomain'] element, including Device Groups, Templates and stacks, Log Collectors, etc etc.
In non-Panorama, therefore NGFW directly, it is slightly different, but still has the localhost.localdomain:
So to your questions:
When do we need to specify the name of the device entry? (e.g. 'localhost.localdomain') - Always Is this value consistent across all Panorama versions? - Yes By leaving it blank, does the value default to something? - No
Hope that helps?
