Hi Ratha,
I am not sure I understand the issue here - normally you configure sub-interfaces to allow 'creation' of more interfaces. These are normally port-channeled back to your switch, then that interface is vlan tagged and that is a 'new' interface. I think you could also use the management interface in the data-plane but you need to remove the management-only command.
If that is not the information you are looking for - shout back.
Best wishes
Mike
