You must install the Advanced Services license to use VDCs besides the default VDC.
When you make an interface a member of an existing VRF, Cisco NX-OS removes all layer 3
configuration. You should configure all layer 3 parameters after adding an interface to a VRF.
You should add the mgmt0 interface to the management VRF and configure the mgmt0 IP address
and other parameters after you add it to the management VRF.
If you configure an interface for a VRF before the VRF exists, the interface is operationally down
until you create the VRF.
Cisco NX-OS creates the default and management VRFs by default. You should make the mgmt0
interface a member of the management VRF.
The write erase boot command does not remove the management VRF configuration. You must use
the write erase command and then the write erase boot command.
