Products

• VCF Automation

Issue/Introduction

• Segments created in NSX with the transport zone being displayed as "Default Overlay Transport Zone <auto-assigned>" are missing on the Aria Automation UI and therefore cannot be added to Network Profiles.
  
  In NSX manager UI, you see the transport zone of the segment set as "Default Overlay Transport Zone <auto-assigned>"  like below.
  
  In Aria Automation UI, the segment does not appear on Service Broker > Infrastructure > Network Profile > Networks > Add Network page like below.
  
  
  
• The NSX mode of the NSX Cloud Account is set as Policy.
• You see below error for the NSX segment in provisioning-service-app.log.

Environment

Aria Automation 8.18.x

Cause

Aria Automation collects NSX segment data using an API, which is based on the NSX mode setting for the NSX Cloud Account.

When the NSX mode of the NSX Cloud Account is set to Policy, Aria Automation expects the transport zone of the NSX segment to be specified in order to collect the NSX segment information.

If the NSX segment is created without the transport zone being specified, Aria Automation cannot properly collect and store the NSX segment data, and therefore cannot display the NSX segment on the UI.

Resolution

To add the segments to Network Profiles, recreate the segment in NSX and specify a transport zone.

For more information on how to recreate the segment in NSX, see Create an NSX Segment.
