Need Help connecting Nexus 9K to 2K.

Hello

I have one Nexus 2232 that is connected to two Nexus 9396.  I have named the Nexus 2232 "FEX 101".  I cannot get FEX 101 to  show online on both 9396's at the same time.  The B side shows online while the A side shows FEX 101 as offline.  Is my configuration missing something?  Can I have the same fex number and port channel on different 9K connecting  to the same 2K? Thank you for your response.[[{"type":"media","fid":"1256786","view_mode":"default","link_text":null,"attributes":{"alt":"Nexus 9396 to Nexus 2232","title":"Nexus 9396 to Nexus 2232","height":"525","width":"694","class":"image-style-none media-element file-default"}}]]

I may be wrong here as I don't have any direct experience with Nexus but I found this thread which as far as I understand it is what you are trying to do and it looks like it isn't supported -

Chris,

Chris,

Can you post the running configuration of the interfaces from both N9K you listed above? Are all the links up/up on the N9K?

Hi Wes, Thank you for you

Could this be a limitation of the Nexus 9000?  Has anyone been successful in creating a VPC on a fabric interface using a Nexus 9000/2000 solution?  All of the Cisco documentation that I've read says it can be done but the examples given show a Nexus 5000 as the spine and a Nexus 2000 as the leaf.

This is the error message that I get when I try to move the fabric interfaces in to a vpc and vice versa:  

9396-A(config-if-range)# int po101

9396-A(config-if)# vpc 101

ERROR: Operation failed: [FEX interface is not capable of acting as vPC]

9396-A(config-if)# int po101

9396-A(config-if)# vpc 101

9396-A(config-if)# switchport mode fex-fabric

Error: Fabric mode not supported on VPC

Thank you Jon.  Its seems that Enhanced VPC is not supported on the 9K platform at this time.
