VNA Inventory items appear under the List but no devices show in the Topology view

Products

• Network Observability
• Spectrum
• Virtual Network Assurance

Issue/Introduction

After upgrade you can no longer see discovered VNA devices in the VNA Inventory > Topology tab but they do appear in the VNA Inventory > List tab. 

All SpectroServer and OneClick servers have been restarted but the issue continues.

 

A check from the database shows the devices are under the VNA Inventory model as you would expect.

Environment

VNA and Spectrum 24.3.3+

Cause

The topology support for VNA inventory has been removed to improve the performance as rendering is taking lot of time when there are more number of access points or devices.
Admins/Operators can see those devices under VNA Inventory of Navigation tab and under List tab of Contents panel.

Resolution

works as designed
