How to check in 11ac mesh logs about the updates on Mesh topology to the Controller?

Environment- 11ac Mesh Topology updates in 6.4.3

Answer- Once  mesh connection is established, mesh topology information is sent by Meshd to the controller. 

The logs for the same can be found in mesh ap debug logs. Below is a sample log for the same:
