    “whenever a virtual Ethernet adapter is connected to the virtual switch or whenever that virtual Ethernet adapter’s traffic would be routed over a dif-ferent physical Ethernet adapter in the team due to a failover event, a notification is sent out over the network to update the lookup tables on physical switches”

    It says “whenever a virtual Ethernet adapter is connected to the virtual switch”, which is a virtual NIC change of link state (link up)
