Validation errors observed after applying Multi vTEP HA profile on the Transport Node Profiles (TNPs) for the compute clusters

Products

• VMware NSX
• VMware Telco Cloud Platform

Issue/Introduction

"Validation errors" as shown below were encountered in the NSX UI while applying the Transport node profile with Multi-TEP HA configuration, 

 

The clusters were configured with two hostswitches , One of the hostswitch was configured with VLAN transport zone only while the other hostswitch was configured with both overlay and vlan tranportzone as shown below 

Environment

NSX 4.2.1.4.0.24765227

TCP 5.x 

Cause

For the Multi vTEP HA config to work, the target host switch must be attached with at least one overlay transport zone. When MultiTEP HA profile is attached to both host switches, then both host switches should be configured with overlay transport zone 

 

Resolution

Re-configure Multi vTEP HA profile only for the required switch in the transport node profile or configure overlay TZ for both the host switches 

Below is a sample host switch spec where vtephaprofile1 is attached with both hostswitches "Switchname1" and "Switchname2"
