The Disable-NetAdapterSriov cmdlet disables Single-Root I/O Virtualization (SR-IOV) on the network adapter. SR-IOV enables network traffic to bypass the software swit
ch layer of the Hyper-V virtualization stack. As a result, the I/O overhead in the software emulation layer is reduced and can achieve network performance that is nea
rly the same performance as in non-virtualized environments.
This cmdlet prevents the adapter from using SR-IOV until enabled again. While SR-IOV is disabled, Windows Server® 2012 and later will not attempt to allocate a virtua
l function (VF) to a virtual machine (VM). If VFs from this network adapter are allocated to any VM, then the VFs are revoked and each VM interface reverted to the sy
nthetic network path.

EXAMPLE 1
PS C:\> Disable-NetAdapterSriov -Name "Ethernet 1"
This example disables SR-IOV on the network adapter named Ethernet 1 and restarts the network adapter.
EXAMPLE 2
PS C:\>$netAdapter3 = Get-NetAdapter –Name "Ethernet 3"
Disable-NetAdapterSriov –InputObject $netAdapter3
A version of the cmdlet that uses the pipeline to select the network adapter named Ethernet 3 and pipes that object into this cmdlet.
PS C:\> Get-NetAdapter –Name "Ethernet 3" | Disable-NetAdapterSriov
This example gets a network adapter named Ethernet 3, and disables the network adapter before restarting the network adapter.
EXAMPLE 3
PS C:\> Disable-NetAdapterSriov -Name "Ethernet 2" -NoRestart
This example disables SR-IOV on the network adapter named Ethernet 1 without restarting the network adapter.
