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

Products

• VMware NSX

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

4.x

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 which will come in a follow up release.

Resolution

Currently there is no fix for this and the KB will be updated with the fix once it is available.
