The VxRail is the building block for each cluster, either Mgmt WLD or VxRail VI WLD. The VxRail virtual distributed switch (vDS) provides the virtual network layer for the system network services that are needed for the VCF solution and provides the underlying networks for NSX-V based WLDs. The virtual port groups on each vDS should be separated using a dedicated VLAN for best performance and security. The VxRail cluster bring-up process requires the following VLANs:
Figure 8. VxRail Cluster VLANs
VCF requires the following additional VLANs created and configured on the TOR switches connecting to VxRail nodes in the management WLD cluster before the VCF bring-up process is started using the VCF Cloud Builder tool.

Note: The Edge uplink deployment for both NSX-V and NSX-T based VI WLD is a manual process that must be performed after the VI WLD has been completed.
The following diagram illustrates the different port groups that are created on the Management workload domain VxRail vDS.
