Learn NSX – Part-09 (Transport Zone)

The Segment ID Pool specifies a range of VXLAN Networks Identifiers (VNIs) to use when building logical network segments. This determines the maximum number of logical switches that can be created in your infrastructure.

You must specify a segment ID pool for each NSX Manager to isolate your network traffic.

A transport zone defines the span of a logical switch by delineating the width of the VXLAN/VTEP replication scope and control plane. It can span one or more vSphere clusters. You can have one or more transport zones based on your requirements.

Log in to the vSphere Web Client and click Networking & Security.
Select Installation under the Networking & Security section and select the Logical Network Preparation tab.
Select the Segment ID menu and click Edit.
Enter the range of numbers to be used for VNIs in the Segment ID pool text box and click OK.
Select the Transport Zones menu and click the green + icon to add a new transport zone.
In the New Transport Zone dialog box:
- Enter the name of the transport zone in the Name text box.
- (Optional) Add a description in the Description text box.
- Depending on whether you have NSX Controller nodes in your environment or want to use multicast addresses, select the appropriate Replication mode (also known as the control plane mode).
- Select the check boxes for each cluster to be added to the transport zone.
- Click OK.
