At times when I’m for example at a customer and need to connect my Laptop to different VLAN’s it’s really nice to add new virtual Network Cards (vNIC’s) on the fly, and be connected to multiple networks at the same time. 
By transforming the Network Cards in your computer, into a virtual switch, and then add Virtual Network Cards connected to that switch, it’s possible to do a bit of network magic.
Here is a part of the script that I run each time I reinstall my PC’s to create the vNIC’s that I need and use the most. The script is also installing the software I need and doing some other minor changes (always a work in progress).

Thanks to my friend and colleague Mikael Nyström who showed me this a few years ago.
