Before windows server 2012, if we wanted to implement dual network card binding on the server, we needed to ask the server manufacturer for the corresponding software, but now the arrival of the powerful windows server 2012 saves us all the trouble, because the operating system itself has The function of dual network card binding, how to realize this function, we will use the experiment to explain to you:
Dual network card bonding has the following two advantages:
1. Realize network fault tolerance: master mode and master mode
2. Bandwidth binding
Experiment preparation:
1. Two windows server 2012 servers.
2. One of the servers has two network cards
3. Ensure that the two servers are connected to the network
First we start to configure the network of server01:
Open the network adapter of server01:
win+R to open the run command:
Enter ncpa.cpl and click OK:
Right-click the Ethernet0 we have selected, as shown in the following figure:
Click Properties, as shown below:
OK, you can see some properties of the network card here, we uncheck IPv4, and then double-click IPv4, as shown below:
Here we check Use the following IP address, and then enter the IP address we want to use properly, here I use the 192.168.10 network segment, as shown below:
Click OK, as shown below:
The system pops up this error because we did not specify a DNS server, here we click yes:
Click OK, our configuration on server01 is over, let's start configuring server02
First make sure that server02 has two network cards:
We press win+R keys at the same time:
Enter ncpa.cpl and click OK:
From the above picture, we can see that our server02 already has two network cards. Attention should be paid here: To make two network cards bound with dual network cards, all configurations must be clear.
Right-click on the two network cards respectively:
Click Properties:
Here we uncheck IPv6, and then double-click to open IPv4, as shown below:
Be sure to choose to automatically obtain an IP address here, let's open the server manager:
Click on the local server:
Click on NIC teaming, NIC is disabled by default, we manually enable it:
After opening the NIC teaming we can see our two network cards, then we click on the task:
Click on New Group:
Here we give the group a name, select our two network cards, and click on other properties:
Because we don't have a switch, in the teaming mode here we choose static teaming, and then click OK:
OK, you can see that our two network cards are combined into one, let's open the network link below:
It can also be seen from the above figure that our two network cards have been successfully combined into one network card. Let's configure the IP of our combined network card tema1:
Right mouse button tema1:
Click Properties:
Here we check IPv6, then double-click IPv4:
Here we choose to use the following IP addresses:
Note: The IP address entered here must be in the same network segment as the IP address of server01, otherwise the network will not be connected:
Here I enter 192.168.10.20:
Click OK
OK, this is the end of our configuration, let's test our dual network card binding:
Ping 192.168.10.20 on server01 -t:
You can see it works. Below we disable a network card on server02:
Check out our PING command:
You can see that our ping command still works:
Next we turn on the NIC we disabled, and then disable the other NIC:
Then look at the PING command:
You can see that our network is still connected.
