Can't configure L3 port in Nexus 7004

Hello there,

 

I hope that someone can help me, I'm trying to configure a L3 port in a VDC (NX_CORE_A) in my Nexus 7004 but I'm receiving the next output and I can't configure it:

 

NX_CORE_A(config)# int eth3/1
NX_CORE_A(config-if)# no switchport
ERROR: Ethernet3/1: requested config change not allowed

 

I have no idea why I'm receiving this output.

 

This is my version:

    Try using a SVI  and assign the port into the vlan .  Some of the nexus modules cannot do direct routing and have to use a different card to proxy the routing.  I suspect the card you are trying this on is a L2 card only .Go here and look at the proxy routing section.  To check to see if the card you are using is L2 only do a "show hardware proxy layer-3 detail" .
