vCloud Director Networking Infrastructure (VCDNI) is a technique for making private systems sponsored by a solitary physical P@sVLAN on your system. When you get more engaged with vCloud, it is one approach to make vAPP sandboxes in your condition. To put it plainly, VCDNI utilizes MAC-in-MAC embodiment. Fundamentally it works by making private VLAN's (you will really observe the port gatherings joined to your vDS) and after that stuffing that information inside a bundle that can be utilized on the physical VLAN. Is the information private and secure? From my experience, the appropriate response is: sorta. In the event that your vAPPs are utilizing VCDNI-sponsored systems administration, and appended to a similar communicate space (the organization arrange), the machines can be hit by any host in that communicate area (and afterward with the utilization of vShield Edge, you can ACL that). To be clear, the default control on a vShield Edge gadget is deny entrance). On the off chance that you have vAPPs in various communicated spaces, they are shielded from each other (on layer 2). One kicker, your virtual Distributed Switch must have MTU set to 1524 (on the off chance that it was set to default of 1500) to take into consideration the bigger header because of exemplification.
