Consider the following scenario:
- You have a Windows Server 2012 R2-based computer that is configured for one or more NIC teams by using Windows NIC Teaming (LBFO).
- You have implemented Windows NIC Teaming (LBFO) in Switch Independent teaming mode by using Hyper-V Port or Dynamic Load Balancing mode. Additionally, you have correctly configured the NICs to use non-overlapping processors. (For more information, see Knowledge Base article 2974384).
- A Hyper-V virtual switch is bound to one of the LBFO teams.
- You start a virtual machine on the Hyper-V server, or you live migrate a virtual machine from one server to another server.
In this scenario, you experience one or more of the following issues:
