vCenter Portgroup does not update nsx vlan-id changes for Segments from NSX T UI.

Products

• VMware NSX
• VMware Cloud Foundation

Issue/Introduction

• The NSX segment VLAN IDs are not shown in the vCenter port group.
• Single VLAN ID flows and it reflected on the vCenter port groups.
• net-dvs -l command on the hosts show that the segments/portgroup has the right VLAN ID tagged.
• There is no problem with the traffic flow as well.
• Below is an example from the logs on how the NSX is passing the IDs:

Environment

VMware NSX-T 3.x

VMware NSX 4.x

VMware NSX 9.0

VCF 9.0

Cause

This is a cosmetic issue and there is no DP impact.
The networks (NSXPGs) cannot be updated by VC user and need NSX Manager changes.

Resolution

The issue is fixed in NSX 4.2.4 and NSX 9.1, available at Broadcom Support Portal.
