Newly created NSX segments not available for import into Cloud Director

Products

• VMware Cloud Director
• VMware NSX-T Data Center

Issue/Introduction

• When creating a new external network and selecting NSX-T Segments, it keeps loading without showing any errors.
• The page remains on loading status and the segments are loaded after waiting few minutes.
• From API side you can observe that the API to get segments is giving response in about 4-5 seconds but in the UI it never gets loaded or it is loaded after few minutes.

Environment

• VMware Cloud Director 10.3.3
  
  
• VMware Cloud Director 10.5 

Cause

• The VCD UI fetches segment data from NSX-T sequentially. Since NSX-T doesn't support direct page-number-based pagination, each VCD request retrieves all segments in multiple steps, leading to excessive API calls.
• For example, with a page size of 25, the system makes about 80 API calls, significantly slowing down the process and causing the UI to freeze.

Resolution

This issue is resolved in VMware Cloud Director 10.6, available at Broadcom Support Portal.
