Explanation

Requirements for a collector virtual machine to analyze traffic from a vSphere Distributed Switch: 1) The source and target virtual machines must both be on a vNetwork Switch, but can be on any 2) The port group on distributed port must have NetFlow enabled. Two methods to migrate a virtual machine from a vSphere Standard Switch (VSS) to a vSphere Distributed Switch (VDS): 1) Migrate the port group containing the virtual machine from a vNetwork Standard Switch using the Migrate Virtual machine networking option. 2)Edit the Network Adapater settings for the virtual machine and select a dvPort group from the
