Hello Anand,
VDC Intercommunication configuration
By default, all ports on the switch are assigned to the default VDC (VDC 1). When a new VDC is created, the super user is required to assign a set of physical ports from the default VDC to the newly created VDC, providing the new VDC with a means to communicate with other devices on the network. Once a physical port is assigned to a VDC, it is bound exclusively to that VDC, and no other VDC has access to that port. Inter-VDC communication is not facilitated from within the switch. A discrete external connection must be made between ports of different VDCs to allow communication between them.
