I have created a LBFO team for use in storage and would like to enable Jumbo Frames. If I do, "Get-NetIPInterface" I get the result:

NlMtu(Bytes) 1500

If I execute, "Set-NetIPInterface -InterfaceAlias "Storage Team" -NlMtuBytes 9000 -AddressFamily "IPv4"" and do "Get-NetIPInterface" again, the MTU still reports as 1500.

  1. Do LBFO Teams support jumbo frames?
  2. If so, is this the correct method to set it? "Get-NetAdapterAdvancedProperty" doesn't seem to have a jumbo frame or MTU setting.

Are you using this with the MS iSCSI Initiator? If so, you probably want MPIO, not teaming. – Doug Luxem Oct 15 '12 at 19:52
We're using the NICS for SMB for our Hyper-V cluster. – CCCPSpy Oct 15 '12 at 23:58

From what I can see the LBFO team inherits the MTU set on the interfaces. So if you use the Set-NetIPInterface -NlMtu on the interface prior to using the LBFO commands to create or add them to a team then you should end up with a team which can use jumbo frames.

Be warned though the MTU is set per address family and also probably requires you to change an advanced adapter setting in the Configure -> Advanced section of the interface properties and as far as I know these are not exposed to the PowerShell interface.
