How Windows Server 2012 implements dual-NIC binding

Before Windows Server 2012 we were on the server if we were to implement a dual-NIC binding, we would need the appropriate software for the server manufacturer, but now the advent of the powerful Windows Server 2012 saves us all the hassle, Because the operating system itself has a dual-NIC binding function, how to achieve this function, the following we use the experiment to explain to you:

The following two points are the main advantages of two-NIC binding:

1. Realize network fault tolerance: Main mode and main mode

2. Bandwidth Binding

Experiment Preparation:

1. Two Windows Server 2012 servers.

2, one server and two network cards

3. Make sure two servers are connected to each other

First we start configuring the SERVER01 network:

Open the SERVER01 network adapter:

Win+r Open the Run command:

Enter ncpa.cpl and click OK:

Right-click the Ethernet0 we have selected, as shown in:

Click Properties, such as:

OK, here you can see some properties of the NIC, we cancel the IPv4 check, and then double-click IPv4, such as:

Here we check the use of the following IP address, and then enter the IP address we want to use properly, where I use 192.168.10 network segment, such as:

Click OK, such as:

The system ejected this error because we did not specify a DNS server, where we click Yes:

Click OK, our configuration on the Server01 side is over, let's start configuring Server02

First make sure that the Server02 has two NICs:

We also press the WIN+R key:

Enter ncpa.cpl and click OK:

There is a picture above can see our server02 already have two network card, here to note: Do double NIC binding two NIC to clear all the configuration.

right mouse button on two NICs:

Click Properties:

Here we cancel IPv6 check, then double hit open IPv4, such as:

It is important to make sure that you choose to obtain an IP address automatically, and below we open Server Manager:

Click on the local server:

Click NIC teaming, NIC is disabled by default, we manually enable it:

After we open NIC teaming we can see our two NICs and then we click on the task:

Click New Group:

Here we name the group and select our two Nic, then click on the other properties:

Since we do not have switches, in group mode we select static groups, then click OK:

OK, you can see our two NICs and combine them into one, and we'll open the web link below:

It can also be seen that our two NIC has been successfully combined into a network card, the following we will configure our combined network card TEMA1 IP:

right mouse button tema1:

Click Properties:

Here we tick IPv6, and then double-click IPv4:

Here we will choose to use the following IP address:

Note: The IP address entered here must be the same network segment as the IP address of the SERVER01, otherwise the network will not pass:

Here I enter 192.168.10.20:

Click OK

OK, here's the end of our configuration, let's test our dual NIC bindings:

Ping 192.168.10.20-t on Server01:

You can see that it's a pass. Below we disable a NIC on Server02:

In the View our ping command:

You can see that our ping command is still in flux:

Let's turn on the network card that we disabled, and then disable the other NIC:

Then look at the ping command:

We can see that our network is still in flux.
