VCE VxRail 3.5 Network Guide and vlan id pairs

Mentioned in the network guide is a passage on page 9 that says "Enter a Name and VLAN ID pair for each VM network you want to create.".  I'm trying to understand why I would need to create a Private Vlan and why I would need a VLAN ID pair when configuring a single appliance.  Any Ideas?

VxRail uses the vSphere Distributed Switch. There is no physical switch in the appliance to facilitate communication between the nodes.

Re: VCE VxRail 3.5 Network Guide and vlan id pairs

So you are saying that IF I don't have any external switch, such as the VDX-6740, that is when I would use a private VLAN to separate the traffic.  Is that correct?  That seems to indicate it would be cabled to itself, at least for VMotion, VSan, etc.

A single appliance contains 4 nodes, each with 2 network ports (4 in the case of the VxRail 60). That is a minimum of 16 ports. These ports need to be connected to a least one external switch. The communication between the nodes (VSAN, vMotion, etc...) runs across these ports and is segmented by VLANs.
