The VLAN preconfigured for the VxRail external management network on the nodes during the manufacturing process is zero, or the native VLAN.
This native VLAN is untagged, which means all network traffic is allowed passage. If you use a tagged VLAN for the VxRail external management network, which restricts network passage, perform the following steps:
- Configure the VLAN on the trunked port as a tagged VLAN.
- Change the default VLAN for the VxRail external management network on the VMware VDS for each of the VxRail nodes to the tagged VLAN.
If you use a tagged VLAN, Dell professional services change the VLAN on the VxRail nodes before performing cluster initialization.
