HOWTO: Enable Jumbo Frames in Windows 2012R2 VMs via #PowerShell

Cleaning up my Inbox, I found this nugget that I had sent to myself and I figured I would share… For reasons that now escape me, a few months ago I had the need to enable Jumbo Frames inside of several VMs (ESXi 6.x). Sure, I could have used the mouse and the Network Control panel to do so, but why wear out the ball on my trackball needlessly when I had a ton of HP keyboards laying about that I could abuse instead… So, off to PowerShell!

Basically, open an Administrative PowerShell and run one of these three sets of commands depending on the type of vNIC you have.

For the E1000E:

$NICNameE1000E = Get-NetAdapter | Where-Object { $_.InterfaceDescription –Like "Intel(R) 82574L Gigabit Network Connection" } | Select -expand nameSet-NetAdapterAdvancedProperty -Name $NicNameE1000E –DisplayName "Jumbo Packet" –DisplayValue "9014 Bytes"

For the E1000:

$NicNameE1000 = Get-NetAdapter | Where-Object { $_.InterfaceDescription –Like "Intel(R) PRO/1000 MT Network Connection" } | Select -expand nameSet-NetAdapterAdvancedProperty -Name $NicNameE1000 –DisplayName "Jumbo Packet" –DisplayValue "9014 Bytes (Alteon)"

For the VMXNET3:

$NicNameVMXNet = Get-NetAdapter | Where-Object { $_.InterfaceDescription –Like "vmxnet3 Ethernet Adapter" } | Select -expand nameSet-NetAdapterAdvancedProperty -Name $NicNameE1000 –DisplayName "Jumbo Packet" –DisplayValue "Jumbo 9000"

As always – Use any tips, tricks, or scripts I post at your own risk.
