So I was wondering how this worked, if I needed a 5500 switch to be both an fc npv switch and an fcoe-npv switch - can I enable both features at the same time? i.e can I enable all of 'fcoe', 'npv' and 'fcoe-npv'. It turns out I cannot. But then again, I don't need to...
If I enable 'fcoe' and then enable 'npv', I not only get NPV for FC, but I do also get NPV for FCoE (by default).
It is a bit of a no-brainer really when you think about it, but it's worth knowing in case you need to work out what features you need.
feature fcoe-npv will just give you NPV mode for FCoE, so no native FC-NPV.
Of course, on your NPIV switch, you still need 'feature npiv' - may sound silly, but don't forget about it!
and also don't forget, on 5500's you enable FC by turning on the 'FCoE' feature.
