The DDP doesn't require any VLAN to be setup in order to work properly.


However if you need to configure VLANs in your network, you can do it at the only condition that you do not put multiple DDP ports in the same VLANs. The reason is that each DDP port must be in a separate subnet and is not allowed to conflict with another port as explained in a previous topic.


So if you want to put each DDP port in a VLAN, each must have its own and unique VLAN.
