Save complete virtual PortGroup information Settings - Powercli

This script I have written to pull information from all the Virtual PortGroup on esxi/vcenter and data is saved in a single CSV file, You can use it as a backup also, It is very helpful when modifying, analysing Portgroup configuration, If you take the portgroup backup with this script frequently you can even tell what are the changes done last time or compare those settings. This has saved my lots of time while troubleshooting my Virtual Standard Switch networking.

Earlier script for collecting networking information
PowerCLI esxi host Physical nic info in nice table format 

Find CDP or LLDP information on Windows Servers

Below are the settings captured and stored in CSV file.
  • Esxi server name
  • PortGroup Name, This will be per esxi server not the common one
  • Vlan Id configured on PortGroup
  • vSwitch name Portgroup resides
  • PortGroup Type (vmkernel or Virtual Machines)
  • Mac Address (If portgroup is virtual machine, Mac address of all virtual machines, else mac address of vmkernel portgroup)
  • PortGroup Security Settings  (Promiscuous mode, Mac address Changes, forged transmits)
  • NicTeaming Settings (Whether they are inherited from vSwitch)
  • Notify Switches
  • Failback, order
  • Active Nics, Standby Nics, Unused Nics
  • Virtual machines count on the portgroup and their name, Ip address,
  • PortGroup Binding compliance
  • MTU Settings
  • Management, vMotion, Ft, vSan enabled for vmkernel portgroup
This is the first screenshot when I am running script, It will collect all the virtual portgroup on the esxi in vCenter and then will collect and store information from each PortGroup in CSV file.
This is the second screenshot I want to show how the data will look like on the console. Some of the information will be blank depending on if portgroup is VMKernel or virtual machines.
Copy paste below code in text file and rename extension to .ps1
  Gets the complete virtual portgroup information  
  This script creates a report of complete virtual portGroup information  
  of the vm’s guest OS  
  Find more information on  
  Make sure you have installed Powercli and can connect to vcenter.  
  PS C:\Temp> .\Get-VirtualPortGroupInfo.ps1

This is how I connected to vcenter server and executed ps1 file. and exported results to csv file, if you don't export information to csv you can view results on csv.
And exported excel/csv file looks like this
Any suggestions and modifications are welcomed.
