Hi there,

 

"The Admin VDC is a specialized VDC for administrative functions but also has a restriction that warrants mentioning. It is not possible to have an Ethernet interface allocated to the Admin VDC and it is not possible to have any L2 or L3 protocols in the Admin VDC. Admin VDC can be accessed only via the Console or Management ports on the Supervisor modules. No “inband” access via an interface, including loopbacks, can be configured. "

 

A great Chalk Talk regarding Nexus 7000 VDCs was provided here a few years ago -- Highly encourage going over it:

You can't allow front panel port to admin VDC, that's impossible.
