Mikrotik Switch Questions

Well, after updating it to 7.21 beta 2, it works perfectly fine. Now, when i try to set PFC to a CPU port/switch, it returns an error (expected) and on the other ports, it can now be set.

However, i’m not sure what profile should I select (cnp, roce or default). Can anyone guide on this?

Can anyone tell me what profile should i select? cnp, default or roce?
