Each VI workload domain requires at least one VLAN for the NSX host overlay network. The VLAN drives the Transport Zone selection the VI workload domain can be a member of.
- Best practice is to configure a new VLAN for each VI workload domain to support the NSX host overlay network.
- Applying the same VLAN to each VxRail cluster added to the VI workload domain ensures that all VxRail nodes are members of the host overlay network.
- Follow these tasks for a new VLAN for the NSX host overlay network:
- Configure the VLAN on the adjacent leaf switches providing connectivity to the VxRail nodes.
- Add the VLAN to each trunked port on the adjacent leaf switches providing connectivity to the VxRail nodes, specifically to the switch ports supporting NSX network traffic.
- If using DHCP to supply IP addresses for the host overlay network, ensure connectivity to a DHCP server supplying the IP addresses.
