Add-VDSwitchPhysicalNetworkAdapter

Is there a way to assign a VMHost's physical NIC to a particular VD Uplink Port?

My Virtual Distributed Switch has 4 uplinks per host.  My blade has 4 physical NICs, two are 10 gig and two are 1 gig.  I want to script a way so the 1st 10 gig NIC (the one with the lowest MAC) gets assigned to dvUplink1 the other 10 gig NIC is assigned to dvUplink2.  The 1st 1 gig NIC gets assigned to dvUplink3 and the 2nd 1 gig NIC get assigned to dvUplink4.  I know how to get a reference the appropriate physical NIC in the host, I just can't figure out how to assign it to a particular dvUplink on the DVS.

Any suggestions?

Thanks,

With

Get-VMHostNetworkAdapter -Physical -VMHost $esx

you can get the MAC and the DeviceName.

And you can use this DeviceName on the Add-VDSwitchPhysicalNetworkAdapter cmdlet on the VMHostPhysicalNic parameter.

Yes, like I said, I know how to get a reference to a particular the Physical NIC.  I just don't know, and what I'm asking is, how do I assign that physical NIC to a particular DVuplink port.

So how would you script:  on vmHostA assign vmnic0 to dvUplink3 on dvSwitch0?

Isn't this done in the order you specify them on the VMHostPhysicalNic parameter ?

Ah, so you're suggesting I pass an array of physical NICs.  Where element 0 would get assigned to DVuplink1, element 1 would get assign to DVuplink2, etc...  Intriguing.

I'll give it a try.  Thanks!

How can uplinks be left blank or the physical NICs be entered in different order?

For example, assume Uplink 1, Uplink 2, Uplink 3, and Uplink 4. How can I do the following assignment?

Uplink 1 => vmnic0

Uplink 2 => <null>

Uplink 3 => vmnic2

Uplink 4 => vmnic1

Thanks for the help.

No it isn't. Not always for some reason. On one of my hosts it starts on dvUplink5 out of 6. The same thing happens if I use the vsphere web client and choose auto-assign.

On my other host it starts with dvUplink1 though.

I would also like to know how to get a predictable result with Add-VDSwitchPhysicalNetworkAdapter.
