It is the first team member to bind to the team after you create it or after the host computer is restarted. Because the primary team member might change in a non-deterministic manner at each boot, NIC disable/enable action, or other reconfiguration activities, the primary team member might change, and the MAC address of the team might vary.In most situations this doesn't cause problems, but there are a few cases where issues might arise.If the primary team member is removed from the team and then placed into operation there may be a MAC address conflict. The primary NIC Team member is a network adapter selected by the operating system from the initial set of team members. The process of disabling and then enabling the team interface causes the interface to select a new MAC address from the remaining team members, thereby eliminating the MAC address conflict.You can set the MAC address of the NIC team to a specific MAC address by setting it in the primary team interface, just as you can do when configuring the MAC address of any physical NIC. To resolve this conflict, disable and then enable the team interface.
