Error: "Mismatch" configuration state on Edge Transport Nodes - NSX

Products

• VMware NSX
• VMware Telco Cloud Platform

Issue/Introduction

• After upgrading NSX, Edge nodes display a "Mismatch" configuration state in the NSX Manager UI, accompanied by an alarm indicating CLI configuration and intent configuration hostname discrepancies:
  
  • Reason: CLI configuration: {"Host name":"NewName.net"},
  • intent configuration: {"Host name":"OldName.net"}

Environment

• NSX 3.x, 4.x
• TCP: 3, 4.x, 4.0.1, 5.x, 5.0. 5.0.1, 5.0.2

Cause

• A discrepancy exists between the Edge node hostname configured in CLI and the intended configuration stored within NSX Manager, often caused by post-upgrade synchronization failures or hostname modification operations.

Resolution

1. Perform a backup of the NSX Manager configuration and Edge Transport Node state before proceeding.
2. Navigate to System > Fabric > Nodes > Edge Transport Nodes in the NSX Manager UI.
3. Locate the Edge node showing a "Mismatch" status in the Configuration State column.
4. Select the Mismatch link.
5. In the resolution pop-up, choose vSphere/Edge Appliance as the source.
6. Click Resolve to trigger the configuration synchronization.
