Private VLANs (PVLANs) are an extension of the VLAN standard. PVLANs can be configured on virtual distributed switches to isolate traffic between virtual machines in the same VLAN.
A primary PVLAN is created on a vDSwitch, and secondary PVLANs are associated with the primary PVLAN. There are three types of secondary PVLANs: Promiscuous, Community, and Isolated. They are depicted in the following diagram:
The virtual machine connections in a Promiscuous PVLAN can communicate with all the virtual machine connections in the same primary PVLAN. When a primary PVLAN is created, a Promiscuous PVLAN is created with the same PVLAN ID as the primary PVLAN.
Virtual machine connections in a Community PVLAN can communicate with...
