FCoE storage and dot1q trunking

We have direct attached Netapp  storage to the FIs configured as fcoe storage ports, the FIs are in  FC-switch mode. I see the netapp flogied into the FIs so the FC part  looks good. On the netapp side we have one 10g interface, e1a, with an ip address on it.  We have another 10g interface, e1b, with vlans attached to it so that interface sends and receives dot1q tagged frames.

All the documentation seems to imply that ip traffic won't work at all on an FCOE storage port.  Yet, e1a works fine while e1b does not.  

Question 1:  My theory is the plain ethernet on e1a works ok but the dot1q tagging on e1b is what actually doesn't work on the FCOE storage port.  Am I correct?

Question 2:   I think to get dot1q working I need to switch to change the FI port type from FCOE storage to Appliance port.  Is that just as simple as chaning the port type via ucs manager?  Does that take the FCOE link offline or anything?

FCoE storage and dot1q trunking

Hello Tod,

Please make sure you have dot1q on Netapp and necessary FCoE VLANs are tagged as native on both FI and Netapp.

Below docs can serve as reference.

Flexpod deployment guide ( Instead of connecting to N5K, we are connecting Netapp directly to UCS FI. Netapp configuration would be similar )
