    Very good to everyone, I wanted to ask you a favor by clearing up a doubt regarding STP. I was looking for official information from the manufacturer regarding the maximum number of switches allowed that can be part of STP but I can't find it. Could it be that someone based on their experience knows how many switches I can add within the same STP topology with the Aruba CX switches?

    Hi, you should look at the Spanning Tree protocol restrictions/best practices other than looking at what any vendor could say about its implementation...I mean...STP is more sensitive to its "diameter" size (the number of hops form the "inner" STP Root to the "outer" - or better the most distant - switch on the topology) other than the grand total of all involved Switches no matter the position they have into the considered STP topology (indeed you can practically and theoretically have a lot of switches directly connected to a core - so with a very small STP diameter - and the STP can be easily implemented, this doesn't necessarily mean that that design is following STP/Topology Best Practices).
