Just as human speech has natural breaks at the ends of words and sentences, TCP flows TCP communication streams also have naturally occurring breaks. The portion of a TCP flow between two such breaks is referred to as a flowlet. When the dynamic mode algorithm detects that a flowlet boundary has been encountered - such as when a break of sufficient length has occurred in the TCP flow - the algorithm automatically rebalances the flow to another team member if appropriate. In some circumstances the algorithm might also periodically rebalance flows that do not contain any flowlets.

Because of this, the affinity between TCP flow and team member can change at any time as the dynamic balancing algorithm works to balance the workload of the team members.

Whether the team is configured with Switch Independent or one of the Switch Dependent modes, it is recommended that you use Dynamic distribution mode for best performance. When you configure a NIC as a Standby adapter, all other unselected team members are Active, and no network traffic is sent to or processed by the adapter until an Active NIC fails. When all team members get restored to service, the standby team member returns to standby status.

You do not need to designate a Standby Adapter to achieve fault tolerance; fault tolerance is always present whenever there are at least two network adapters in a NIC Team.

Important Switch dependent teaming requires that all team members are connected to the same physical switch or a multi-chassis switch that shares a switch ID among the multiple chassis.

Depending on the switch configuration mode and the load distribution algorithm, NIC teaming presents either the smallest number of available and supported queues by any adapter in the team Min-Queues mode or the total number of queues available across all team members Sum-of-Queues mode.

If the team is in Switch-Independent teaming mode and you set the load distribution to Hyper-V Port mode or Dynamic mode, the number of queues reported is the sum of all the queues available from the team members Sum-of-Queues mode. Otherwise, the number of queues reported is the smallest number of queues supported by any member of the team Min-Queues mode. When the switch-independent team is in Hyper-V Port mode or Dynamic mode the inbound traffic for a Hyper-V switch port VM always arrives on the same team member.

When the team is in any switch dependent mode static teaming or LACP teaming , the switch that the team is connected to controls the inbound traffic distribution. The host's NIC Teaming software can't predict which team member gets the inbound traffic for a VM and it may be that the switch distributes the traffic for a VM across all team members. When the team is in switch-independent mode and uses address hash load balancing, the inbound traffic always comes in on one NIC the primary team member - all of it on just one team member.

Since other team members aren't dealing with inbound traffic, they get programmed with the same queues as the primary member so that if the primary member fails, any other team member can be used to pick up the inbound traffic, and the queues are already in place. Following are a few VMQ settings that provide better system performance. The first physical processor, Core 0 logical processors 0 and 1 , typically does most of the system processing so the network processing should steer away from this physical processor.

Some machine architectures don't have two logical processors per physical processor, so for such machines, the base processor should be greater than or equal to 1. If in doubt assume your host is using a 2 logical processor per physical processor architecture.

If the team is in Sum-of-Queues mode the team members' processors should be non-overlapping. For example, in a 4-core host 8 logical processors with a team of 2 10Gbps NICs, you could set the first one to use the base processor of 2 and to use 4 cores; the second would be set to use base processor 6 and use 2 cores.

Configure your environment using the following guidelines:. Before you enable NIC Teaming, configure the physical switch ports connected to the teaming host to use trunk promiscuous mode. The physical switch should pass all traffic to the host for filtering without modifying the traffic. Never team these ports in the VM because doing so causes network communication problems. It's easily possible to configure the different VFs to be on different VLANs and doing so causes network communication problems.

Rename interfaces by using the Windows PowerShell command Rename-NetAdapter or by performing the following procedure:. Ok, you will have to configure the switch ports for LACP I am not familiar with Cisco iOS, so I can't give you specifics, but it is something you will need to do as well.

So, you'll want to setup the switch first, then do what you outlined above, and you should be all set. When is a Cisco switch not a Cisco switch? When it's a Linksys That leads me to believe that the simple act of teaming should "just work" I would double check the other servers "teaming" This server is already giving us a lot better performance in terms of file moves and sending backup images to my NAS than the one that ISN'T set up as a team, but even after all the reading I still haven't gotten my head around all of the options and settings in teaming.

Our office is fairly small, relatively speaking, and we don't have a ton of apps hogging bandwidth. We also are limited in our internet upload bandwidth, so this setting is MORE than enough. I think with these NICs teamed like the other, it will serve my purposes perfectly. To continue this discussion, please ask a new question.
