Shutting down/disabling subinterfaces

[scourge]

I am very new to the PANOS world so I will apologize in advance if this is obvious, however my search of documentation and knowledebase did not yield anything. I have been looking for a way to administratively shut down sub interfaces. Is this possible? While it's easy enough to shutdown a physical interface by assigning it's link-state we're not seeing a way to do the same for an individual sub-interface.

Good luck.  I'm moving from Fortinet to Palo Alto (by someone else's direction) and the UI is like taking a 15 year step backward.  I'm amazed at how many little things I've gotten used to in Fortinet that don't exist in Palo.  I go off and search to see if I'm missing something and, like this thread, I find an ancient thread indicating that Palo just 'doesn't do that'.  And there's always the 'submit a request' line, as if that gets anywhere.  It's as if Palo's interface was designed by someone who has never managed a firewall before and architectural decisions were designed by someone who's never managed a network before.  Beyond frustrating.....
