We had this problem with the nexus 5K connected to the MDS9124.  It's because of VSAN1.

I think if you don't use vsan1, then things will be fine.

AND also, the MDS 91x4 don't support F port trunking.

although we don't use vlan 1 we got the same message every 20 minutes on some interfaces

%NPV-5-FRAME_DISCARDED: %$VSAN 998%$ Frame with unexpected FC2 status 0xc received

I enabled some debug to find out senders source of these frame by using:

• debug npv errors vsan 999
  
• debug npv events vsan 999
  
• debug fc2 error vsan 999 interface fc2/2
  But the onyl additional info I got was:
  

2012 Nov 29 09:34:27.335338 npv: npivp_fc2_msg_recv: Unknown fc2 status 12

What debug I've to use to find out the source?
