A couple of months ago we had to create hundreds of portgroups on a dvSwitch on one of our environments. Doing this manually is pretty tedious, even if you only have to create the portgroup and add a VLAN tag.

In this particular case I also had to set the uplink policy and add two vCenter permissions to each portgroup. This would take ages doing it manually but not with the script I created which is shown below.

It’s an easy script, I could make it fancier and add an input-based variable for the vlan range, distributed vSwitch, usergroups and roles but since it’s pretty static for the environment it’s used for, I kept it simple. If you want to use this script just edit those and you are good to go! Maybe I will update this blogpost in the future with the input-based variant.
