Extreme networks switches- no output on interfaces, problem

I'we seen lot's of posts with same problems not geting output on ports. Each and every time youve suggested to have flow export on all ports. Since i'we enabled sflow on all ports on switch and geting same result, question is what to do.. I tryed on several diferent switches with same results..
If you could good enough to specify exact sflow configuration on extreme xos or extremeware switches...
