New-NetIPAddress : Invalid parameter InterfaceAlias

hello,

I am trying to configure an IP address for a VM.  

My version of PS is 5-1-17134-407

I issued New-NetIPAddress -IPAddress 10.2.0.1 -PrefixLength 24 -InterfaceAlias "vEthernet_Lab_Switch"

as well as New-NetIPAddress -IPAddress 10.2.0.1 -PrefixLength 24  to force the Interface value.

I get the error posted above

thanks

Joe
