One of the new features of VMware Horizon View 5.2 allows you to create pools with different portgroups or network labels.
As part of the configuration process you have to generate a configuration file, and for that you need to run a command with lots of parameters.
I found a way to generate most of the difficult parameters, so you don't spend half an hour (or more) trying different combinations of parameters.
All the info below.
All you have to do is to copy & paste the function below in a "View PowerCLI" console (not the same as "PowerCLI" alone) and then run the command GenerateNetworkConfFile
I include some execution examples below.
If you have issues or suggestions please submit a comment.

Does this work with view 7.1
ReplyDeleteHello, with the changes to PowerCLI including the View modules, do you know if it is possible to do the same thing? I am having a heck of a time getting this to work with the modern PowerCLI.
