Before performing a piece of network maintenance I wanted ensure I had an up-to-date list of network information for all ESXi servers.

I was apprehensive to refer to old documentation incase something had changed.

To do this I used PowerCLI, specifically "Get-VMHostNetworkAdaptor" to retrieve a current set of information from all VM hosts containing networking information.

List VM host network details and output to the PowerCLI console:

Get-VMHostNetworkAdapter | select VMhost, Name, IP, SubnetMask, Mac, PortGroupName, vMotionEnabled, mtu, FullDuplex, BitRatePerSec

Output to CSV VM host network details:

Get-VMHostNetworkAdapter | select VMhost, Name, IP, SubnetMask, Mac, PortGroupName, vMotionEnabled, mtu, FullDuplex, BitRatePerSec | Export-Csv C:\VMHostNetworkDetails.csv

Example CSV Output:
