Using private VLANs
Private VLANs (PVLANs) are an extension of the VLAN standard. PVLANs can be configured on virtual distributed switches in order to isolate traffic between virtual machines in the same VLAN.
How to do it…
Identify the types of PVLANs available and the functionalities of each.
Determine the use cases for the PVLANs and identify whether the PVLANs can be used to satisfy the design requirements.
Design the PVLANs to meet the design requirements.
How it works…
A primary PVLAN is created on a vDSwitch, and secondary PVLANs are associated with the primary PVLAN. There are three types of secondary PVLAN: 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...
