I wanted get a list of port groups and their type (kernel, console, virtual machine) from a series of hosts, however the only thing I could find that was even close was a POSH script in the VMTN forums that was posted by LucD.
Using that script for inspiration, I essentially duplicated the functionality, but using the perl toolkit. This script gives me an easy to read (and parse…) list of portgroups, the vSwitch they belong to, and the type.
