vSphere Networks
Before you add storage and virtual machines
to an ESXi system, you should have completed networking setup. This chapter
describes how to set up virtual switches in the vSphere environment.
Virtual Switches Using a Distributed Virtual Switch DistributedVirtualSwitch managed object is a virtual network switch that is located on a vCenter Server. A distributed virtual switch manages configuration for proxy switches (HostProxySwitch ). A proxy switch is located on an ESXi host that is managed by the vCenter Server and is a member of the switch. A distributed switch also provides virtual port state management so that port state is maintained when vCenter Server operations move a virtual machine from one host to another.VMware Standard Virtual Switch Sample Code Reference
