See Appendix D: VxRail network configuration for guidance on all the settings that must be collected to perform VxRail cluster automated initial build.

• The external VxRail management network, which represents the overall management for VxRail, Cloud Foundation and NSX-T, is the native VLAN by default. Since the typical Cloud Foundation on VxRail deployment has more than one VxRail cluster, it is advisable to select a value other than the native VLAN.
• You can choose to have VxRail Manager discover the nodes to form a cluster either through automatic discovery, or by manually ingesting the nodes into VxRail Manager. With automatic discovery, the internal VxRail management network VLAN is 3939 by default. Since the typical Cloud Foundation on VxRail deployment has more than one VxRail cluster per leaf switch pair, it is possible that an existing VxRail Manager will detect the new powered-on nodes in the rack on this same network. To bypass this, a new VLAN can be set for the second and subsequent VxRail clusters. Dell Technologies will change the internal management VLAN on each VxRail node to the recorded value before cluster formation.
• The vSAN and vMotion VLANs should be unique for each VxRail cluster. Using a unique VLAN for vSAN and vMotion removes the possibility of conflicts when multiple VxRail clusters are sharing a set of switches.
