Hi Vineet,
You do not need to insert anything under Driver Setup. Anytime you are using NI switches, you can simply click Configure NI Switches when creating a NI Switch Executive Virtual Device to configure the topology settings of those switches.
Just so you know, you can insert information under Driver Setup, and then you wouldn't have to use the Configure NI Switches wizard. More detail on what to insert under Driver Setup can be found in the following KnowledgeBase:
How Do I Create a Virtual Switch and Use it in my Application?

In short, you would type "Topology:" followed by the topology name such as "2569/100-SPST" or "2529/2-Wire 4x32 Matrix".
Let me know if you have further questions or if this does not resolve your issue!
