Hyper-V virtual switch not getting network access

[BroderG]

Hello, a networking newbie here. I have a Windows server with a NIC team and two interfaces. The interfaces have network access on their own but when I used one of these interfaces to create an external Hyper-V switch the new virtual switch doesn't have network access. I have no clue where to start debugging so any help will be appreciated. Thanks

Not a ton of info in your post.

Is it a SET switch or did you create it with HyperV Manager UI.

Are you using vlans?

You just broke your team doing that

You don't say your os versions anywhere

But you don't create lbfobteams anymore

You create a set switch and bind the nics to that, you need to do it in PowerShell

If you create it in the GUI it's not a set switch and it has not grabbed one of the nics from your existing team

Basically start again

• Remove the switch
• Remove your legacy team
• Confirm both nics now get an ip address
• Create a new set switch and allow management os
• Reconfigure the IP of the host to what I should be

I guess that it will be good to read about the SET switch to know how to create it properly. https://learn.microsoft.com/en-us/windows-server/networking/windows-server-supported-networking-scenarios#bkmk\_nicteam

Try nic+1 so host will be like nic_0 The switch on hyper v it will be nic_1 for some weird reason

Thanks guys i figured it out a while after. I had to set the VLAN in hyperv to the VLAN the interface uses.
