Windows Server 2025 cannot create vSwitch with network teaming.

Question

Hello, We found a problem when create vSwitch by using network teaming adaptor on Windows Server 2025 following the image below.

We tried to run command for enabling or using embedded teaming but still not working

Should have to revert back to Windows Server 2022 ?

Answer 1

no, but to answer it correct, there are some infos missing!

How many physical Network Adapters are in your Host and how many networks are connected.

For Example your Host has 4 network adapters, you can bulid a team with 2 adapter in windows server management console to use it as the host adapter.

But then you can not bulid a switch on this team or any other Team.

If the other two adapters are same connected with all the vlans your vms needed. You can build a new-vmswitch with them.

Example for two adapter named: "PCI4 Port1 VLans" and "PCI4 Port2 VLans"

New-VMSwitch -Name VLans -NetAdapterName "PCI4 Port1 VLans","PCI4 Port2 VLans" -EnableEmbeddedTeaming $true -MinimumBandwidthMode Weight

No Teaming in Windows is possible if you want to build a vmswitch. The vmswitch embedded teaming has two uplink ports (physical adapter) and that is the redundancy
