However remember that Omada is a SDN so its primarily expected to have a router and switch controlled by the OC200 to enable full integration.    Yes manual is possible, but its not as elegant.

Try looking at Profiles and see if you can create one, apply that to your managed port and hopefully it will do what you require

P.S.   Omada questions are better posted in the business forums as they are buisness products, you will likely get a lot more response there
