The tasks to configure the switches to support VxRail cluster networking are basically the same when preparing to deploy the management domain or any VI workload domain.
For the internal VxRail management network that is used for node discovery, the default VLAN configured in the factory on each node is 3939.
If this VLAN is common across nodes for multiple VxRail clusters, then each VxRail Manager instance can discover all the nodes
To restrict node discovery only to the nodes to be used form a single cluster, then configure a unique VLAN on the switches
The default VLAN of 3939 configured in the factory on each node must also be updated if a unique VLAN for this cluster is configured on the switches
