NIC Teaming Windows Server 2012 R2

What is NIC Teaming? A new feature in Windows Server 2012 R2, NIC team

is a collection of network interfaces that work together as one.

Benefit of NIC Teaming:

Bandwidth aggregation.

Redundancy, NIC teaming protects the server against NIC failures.

NIC teaming can be implemented at the software level, so there is no need

to purchase specialized server hardware, and you can create NIC team

consisting of NICs from multiple vendors.

NIC team can be huge, you can combine up to 32 physical NICs into a NIC

team.

5. From “NIC Teaming Console” create “NIC Team name” then picking

the network adapters that are included in the team, then click on

“Additional properties”.

6. Additional properties include some additional options:

a) Teaming mode: there are

three different teaming

modes. 1) Switch

Independent: lets you

build a NIC team without

having to worry about

your network switches.

The NICs that make up

the team can even be connected to multiple network switches. 2)

Static Teaming: requires you to configure both the computer and the

network switch so as to identify the links that make up the team. 3)

LACP: is based on link aggregation. The advantage of this mode, is

that you can dynamically reconfigure the NIC team by adding or

removing NICs your needs dictate.

b) Load Balancing Mode: lets

you choose between two

options: 1) Address Hash: best

choice because it allows traffic

to be load balanced across all of

the NICs in the team. 2) Hyper-V Port: assigns each virtual machines

traffic to a specific NIC. The problem is that virtual machines are

unable to take advantage of distributing traffic across multiple NICs.

c) Standby Adapter: lets you

designate a NIC as standby

spare. If a NIC in the team

were to fail, then a spare is

on hand to take over. That

you can only designate one

NIC as a standby adapter.

Windows does not support

having multiple spare adapters.

7. Set the VLAN for the new teamed interface from “Primary team

interface” windows. This is highly dependent on how the rest of your

system configured. Leaving this set to “Default” works for this example

then click “OK”
