The following script will add some nice host network information into an object which is exported to a csv file for passing to the network guys or can be used to find your server in that mess of cables that are always meaning to be tidied in the data center. – Added VSwitch

You will get:
Host,
Physical Nic Name
Speed
MAC
Switch Device ID
Port ID
Observed Network ranges
VLAN’s

  1. # Set the VI Server and Filename before running
  2. Connect-VIServer MYVISERVER

  14.      foreach($Hint in $pnicInfo){
  15.          $NetworkInfo = "" | select-Object Host, vSwitch, PNic, Speed, MAC, DeviceID, PortID, Observed, VLAN
  16.          $NetworkInfo.Host = $vmhost.Name
