Using NIC Teaming and a virtual switch for Windows Server 2012 host networking Updated on July 20, 2014 By Windows Guy 24 Comments Whiteboard overview and step-by-step demonstration of using the native NIC Teaming in Windows Server 2012 combined with host level virtual network adapters v… More Windows 8.1 Networking Articles By Windows Guy 24 Comments Tony Wood July 20, 2014 Great job thanks very much. I have just started a Hpyer-V design so this has come in very handy as I was going to opt for the normal VMWare / Windows 2008 design. This solution make more sense, nice one :-) matt vorwald July 20, 2014 can i do all this using the gui? I know powershell is the hot new thing but i like to know where to click for these options. thanks! iAnguel July 20, 2014 Nice explanation. Unfortunately, other sources say that for performance reasons one should never create the NIC team on the host but should create teaming in the guest VMs instead. That way one could also use SR-IOV for the teams. Shannon Brooks July 20, 2014 Thanks for the great video John. I’m having trouble with the VM network… can you explain what you mean by VM traffic a little better? My understanding is that if they all share a teamed address that the VMs will connect directly to the switch, but that you could do QOS on each VM. Jason Speer July 20, 2014 Great video, thanks for that! brian7m3 July 20, 2014 Great video – thanks! I basically am having the same issue as MrZami1981. You cannot choose an adapter for VM’s to use when in the settings for a VM, you can only choose a switch. However, you show creating a virtual NIC for the VMs to use and assigning a weight to that. How can that be implemented? Thanks John Patterson July 20, 2014 Is there an easy way to tag each vmnetwork adapter interface with a VLAN? We are operating on all trunked switch ports. Also, would a dedicated vmnetwork adapter be necessary for SMB storage traffic (like you would in a VMWare world)? Taking us a little while to break ourselves of the old VMWare methodologies! Thanks! Ashwin Pawar July 20, 2014 Thank you John. That’s brilliant stuff, very easy to follow. A request – Could you also do a video on ‘HYPER-V 2012 Virtual Switch, specifically around the differences between ‘switch mode’ and ‘switch independent mode’. Thanks -Ashwin Ken RQ July 20, 2014 A good tutorial John, clean & concise. Thank you. DomX2008 July 20, 2014 Very good tutorial, I will be changing my dedicated NIC’s to this set up! Thanks for the valuable information!! John Savill July 20, 2014 Network adapters will only run at the available speed so they will just run at 1Gbps so should be fine. John Savill July 20, 2014 Yes but don’t mix speeds as very unpredictable things will happen. 123ypaul July 20, 2014 GREAT GREAT tutorial. Thank you very much ! Dorman LAB July 20, 2014 A real eye opener… Cheers. Krunal Patel July 20, 2014 I’ve heard different stories around this – but can NIC Teaming increase bandwidth on a local network? Michael Mitrou July 20, 2014 Hey just a quick question. I have 4 NICs in my server (two are 1 gb/s, two are 10 gb/s). They are all connected to a 1 gb/s switch, so I’m not taking advantage of the 10 gb/s speeds regardless. If I have one NIC team with all 4 of these interfaces as members, will this cause any problems? Will it just treat the two 10 gb/s lines as 1 gb/s and everything will be fine, or will this cause any unforeseen problems? Thanks. John Savill July 20, 2014 Jumbo Frames are basically invisible to this. Just make sure all adapters have it enabled then you will send bigger packets which will proportionally make more traffic be used for the data content rather than packet overhead. Er. Kirpal Kaushal July 20, 2014 ++ Now Created Team2 with rest of 2 NIC Cards, now Created 2 Interfaces over Team2 via Add Interface Option in NIC Team Console of Windows 2012, now Assigned Management IP Address, Subnet Mask, Gateway, DNS Server in One Newly created Interface and Only IP Address and Gateway for Heartbeat in Another Interface Zer0kbps July 20, 2014 I have a similar setup using NPAR on 2k8r2 but I cannot get the VM traffic to team without MAC Collisions, this looks way better Max Williams July 20, 2014 I am really just starting out in IT and have found this massively helpful.Thank you so much MrZami1981 July 20, 2014 I have two NICs in the Host and make a Team with them. After this i create 3 Adapter (live Migration, mgmt (host), vms). Weights are 35 / 15 / 50). How can i connect the vms Adapter with the vms on the host, so that they get the bandwith weight? I only can select the virtual Switch for the Adapters of the vm. 2006minesh July 20, 2014 Brilliant video John Brian Scholl July 20, 2014 I was reading Live Migration networks can benefit from Jumbo Frames. How does Jumbo Frames add to the mix? Brian Scholl July 20, 2014 Would it be ok to create a Team with NICs from different adapter cards? So if you have two 4 port network cards can you bind two adapters from each? Comments are closed.
