Thanks for the clarification both on capability and diagram. i miss read the picture because looking at the left i saw (bottom to top) 've mode' 'npiv mode' and 'npv mode'. however i now see on the right the labelling of 'fi' 'upstream fcf' and 'core fcf'.

just to nit pick, i think you intend to say 'fcf with npiv enabled' rather than 'npiv switch'.
