I've been fighting with trying to set the MTU to 9218/9000, but come to find out it's not available until degrading my SDN network and putting into standalone mode.

This isn't a new request, but why is it not available yet?? 

Running on an OC200 with 5.6.4 - MTU editing is available on my TL-SG3428, but not my 10g switch (TL-SX3008F), which could actually benefit from Jumbo Frame.

I had been told by chat support that I could change the setting via the console, but 'enable-admin' only works when not managed by Omada!
