Which network settings are only available with vSphere Distributed Switches?

Private VLAN (PVLAN) on vNetwork Distributed Switch

Primary PVLAN – The original VLAN that is being divided into smaller groups is called Primary, and all the secondary PVLANs exist only inside the primary.

Secondary PVLANs – The secondary PVLANs exist only inside the primary. Each Secondary PVLAN has a specific VLAN ID associated to it, and each packet travelling through it is tagged with an ID as if it were a normal VLAN, and the physical switch associates the behavior (Isolated, Community or Promiscuous) depending on the VLAN ID found in each packet.
