Hi York,
I'm sorry I'm late replies.
Thanks for reminding me. We have some investigates and then depend on the document we think both snoop request and DVM are supported on those port. So we think the setting should be ok in here.
Best Regards, Yuan Yao

I'm not sure both snoop request and DVM are supported on every port. Do you need to check them before setting?
