How to Configure NIC Teaming on Windows Server

Hello and welcome to another useful article about Windows Server. In this article we will talk about NIC Teaming and how it has improved over time, particularly with the modern versions of Windows Server 2016 and 2012 R2 .
indeed without far bustle, let us dive right in and see what NIC Teaming is all about .

NIC Teaming Overview

NIC Teaming is a very nice Windows network feature of speech that lets us use more than one arranger in a opposite mode ( team ) for better speed and more redundancy. When enabling NIC Teaming, we will need at least two adapters present on the Windows Server car, and that ’ s about it. Yes, precisely two physical adapters, no supernumerary software or what not .

In the past ( anterior to Windows Server 2012 R2 ), in arrange to perform NIC Teaming, we would have needed two adapters which were from the lapp seller, and a third-party software that would make the team possible and present the OS with just one “ virtual ” network batting order .
immediately from Windows Server 2012 R2 and up, this is built-in and its hardware agnostic. This means you can use whatever network cards you want and the team will work like a capture .
now, let us deep dive in NIC Teaming and see it in action !
When we are teaming adapters, we are taking two or more physical adapters, improving to 32, which are connected to the same throw, or different switches, and we are presenting them as one NIC to the operate system .
thus, all the traffic from the OS will pass through that one, let ’ s call it virtual NIC and then it will pass load balanced between all the physical NICs assigned to that one virtual NIC .
immediately let ’ s configure NIC Teaming so we can see how all of this works .

Create a NIC Team in Windows Server

beginning, we go into Server Manager and click on the local server to bring up the splashboard .
server manager
As we can see NIC Teaming is set to Disabled. Let ’ s click on that Disabled link and see what happens .
server manager nic teaming
We are presented with this NIC Teaming dialogue box where we can create a newfangled team using the two network adapters that we have available to us, which are Ethernet0 and Ethernet1 2 .
so, let ’ s go to Tasks, and click New Team .
create new team
In the New Team dialogue box, we have several options to choose from :
new team choose adapters
Let ’ s go through each one by one and see what they do.

The Team Name is the list of the virtual NIC as we will see it in the network connections booklet. This can be anything you want, I chose EthernetTeam .
then we have to select the members of the team. We can choose to have several teams as it ’ sulfur not required to add all the NICs under one team .
then we have A dditional properties. now, I had to expand that list, since by nonpayment it ’ sulfur hide. Which means, it would be enough to fair click OK after you selected the NICs and everything would be fine .
But in our case, we like to go into bantam details, so permit ’ s see what each of the option does .
Teaming Mode is the mode the team will work on. We have respective options : Static Teaming, Switch Independent and LACP .
choose teaming mode
We have one which is switch autonomous and we have two which are switch subject. LACP stands for Link Aggregation Control Protocol. The switch mugwump options mean that we do not have to make any shape changes on the switch side .
Using Switch Independent means that outgoing traffic will be load balanced using the algorithm we choose, but since the switches are not mindful of the load poise, the entrance traffic is not going to be lode balanced .
Static configuration is where we configure the ports on the switch and plug the net cards in those specific ports. This room the switch over is mindful of the team and all traffic will be load balanced .
LACP is a lot more dynamic. We configure the trade rather than individual ports, which means that we can move the cables around and we would inactive get a load balanced scenario .
nowadays we besides have to choose the load balancing algorithm .
choose load balancing algorithm
We have three of them : Address Hash, Hyper-V Port and Dynamic. now let ’ s see what each does .
The Address Hash algorithm uses attributes of network traffic, port, IP address and MAC address to determine where the traffic should go to .
The Hyper-V port algorithm will tie a VM to a specific network wag in the team. This works well if you have a lot of VMs since it ’ s a very dependable luck they will be distributed good between the adapters.

The Dynamic algorithm, which Microsoft recommends, uses specification from both worlds, address hash and Hyper-V to load poise the data .
Once we are done with the above shape, we click OK and wait for the team to come on-line .
Thank you for taking the time of reading this article and come second for future articles on Windows Server. enjoy !
