Wrong connection details on interface tab after reconfigure model action

Products

• Network Observability
• Spectrum

Issue/Introduction

You create manual connections with context menu "start connection" from switch x interface x to switch y interface y and see a new connection in topology view.  You also see it in the interface tab on the columns "Device Connected" and "Port Connected". 
You can delete this connection from the topology view and the entries in interface tab are removed. This is expected behavior and it works perfectly well. 

However, after running reconfigure model, a connection between the interfaces can be established or deleted, but this is no longer displayed correctly in the interfaces tab until several hours later. One solution is to restart Tomcat and the spectrum console.

This problem occurs with every device type.

Environment

Spectrum 24.3.x

Cause

When we reconfigure the model the listener is getting corrupted/deleted so when we delete the connection the interface remove listener does not get fired and hence leaves the interface connection details stale for this reconfigured model.

Resolution

This has been resolved in the code and is being added to 25.4.1 at the time of writing this document in September 2025.
