Throughput by traffic type on a vSwitch and/or distributed switch

Hello,

I am currently working on a piece of software that determines how much of different types of traffic is flowing through switches in my VM environment. I am collecting throughput information based on traffic flow on my pNics (see vSphere 5.5 Documentation Center ). I am using the throughput.usage.trafficType counters (e.g. throughput.usage.ft, etc) to gather this information.

Question: What happens if my switch isn't configured to handle a certain traffic type? Say, I don't want any FT traffic flowing through my switch. What will the value of the throughput.usage.ft counter be in that case? Just a zero? Or to be more specific, is there any way to determine, looking just at the counter value for all pNics, whether or not the switch supports a particular traffic type?

Thanks!
