Server 2012 now supports NIC teaming, previously you could use HP tools to achieve this in Server 2008 R2 and below, but officially it was never supported by Microsoft.

Network teaming

Setting up a NIC team in Server 2012 is really simple. You just need to know where your Server is plugged into first on your switches.

1. Open Server Manager, Click on NIC Teaming

2. Under tasks click new team

3. Enter your name, select your adapters, and configure your advance network settings which we will talk about later.

And click OK and we are done.

Jumbo Frames

Assuming we have setup jumbo frames on the network switch, lets look at doing this on the Server.

This is done via our new best friend powershell. So open up a PS console with administrive rights;

Set the following for each physical adapter;

Set-NetAdapterAdvancedProperty -Name “NAME-OF-NIC” -RegistryKeyword “*JumboPacket” -Registryvalue 9014

For any Teamed Adapters you need to set;
NETSH INTERFACE IP SET SUBINTERFACE “NAME-OF-TEAMED-NIC” MTU=9000 STORE=PERSISTENT
