3- NIC Teaming

  1. 1. Network Tutorials 1 Network Technician / copyright 2016Done by: Fahad Al-Balushi 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. Windows Server 2012 R2 Switches Host with all interfaces connected to the same switch Windows Server 2012 R2 Switches Switches We recommend to use this NIC Teaming configuration Host with all interfaces connected to different switches
  2. 2. Network Tutorials 2 Network Technician / copyright 2016Done by: Fahad Al-Balushi How to configure NIC Teaming Windows Server 2012 R2? 1. Go to “Server Manager Console” and then click on “Local Server”. 2. On the “Local Server”, select “Enable NIC Teaming” to configure the Networks.

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.

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”
