Hi Sir,
I tried to installed a new windows 2012R2 and imported a 2012R2 server which residing at 2012R2 hyper-v host .
The network adapters of both VMs in powershell show {degraded,protocolversion} , but it doesn't show it in hyper-v console :

Now , I'm waiting for the windows update to finish latest updates installation .
I'll keep you updated .
Thanks for your understanding .
UPDATE:
Now , windows update made some changes (nod1 is not installed windows update , nod2 installed some windows updates ) :

But VM NIC still show "Degraded" .
Best Regards,
Elton
