Minimum 1600, but 1700 is the recommended minimum to be future proof as NSX-T might start using additional features requiring larger Geneve headers one day.

Or just set it to 9000 and be done with it 😉

do a sure shoot ask always for Jumbo frames, just when you have a WAN link check if possible 1600 sometimes is a challenge to have this as payload size.
