I'm now to the FMC API, and FTD in general. I have been tasked with creating an automated process to disable a subinterface on an FTD. I am able to pull the subinterfaces, but do not appear to be able to change the state via the API. I have also tried fplogicalinterfaces, but can't seem to pull any data from that. Is this something that simply isn't supported yet? Any recommendations on alternative ways to disable a subinterface?
