Cannot Configure VPC Connectivity Profile for Distributed VXLAN Connection(Error: "TN Minimum Version >= 9.1.1.0")

Products

• VMware NSX

Issue/Introduction

• When attempting to configure the VPC connectivity profile for Distributed VXLAN Connection, the system throws the following error message: This feature requires TN Minimum Version >= 9.1.1.0.

Environment

NSX 9.1.1.0 and later

Cause

This issue occurs when the deployment architecture does not meet the necessary prerequisites for VXLAN-backed VPC connectivity profiles:

 

1. The underlying Transport Nodes (TN) do not meet the minimum software version threshold (>= 9.1.1.0).

2. The environment lacks the mandatory advanced networking services configuration required for distributed VXLAN connections.

Resolution

• Verify that each host transport node in your NSX environment is running ESX 9.1.1.0 or later.

• Use the following API call and request payload to set the host_tn_min_os_version value.

  PUT https://<nsx-mgr>/policy/api/v1/infra/sites/default/enforcement-points/default/host-transport-nodes/feature-opt-in 

  {
   "host_tn_min_os_version": "9.1.1.0"
}

• To retrieve the current host_tn_min_os_version value, you can use the following API call.
  GET https://<nsx-mgr>/policy/api/v1/infra/sites/default/enforcement-points/default/host-transport-nodes/feature-opt-in 

Example response:
    {
      "host_tn_min_os_version": "9.1.1.0",
      "resource_type": "FeatureOptIn",
      "id": <id>,
      "display_name": <display_name>,
