Subject: Aruba AOS-CX - Spanning Tree Topology Change History
Hi,
I have an Aruba CX 6200F (AOS-CX). Previously, I used an Aruba 2930F (AOS-Switch).
In AOS-Switch, when I wanted to see Spanning Tree topology changes received, I used the command "show spanning-tree topo-change-history received".
But in AOS-CX, I don´t know how to look Spanning Tree topology changes received.
Does anyone know which command is the equivalent in AOS-CX?
Thanks!
