Here is another one that I found that may make more sense.

Would I need STP enabled on all 3 switches and the root bridge set to the core switch or just STP enabled on the core?

I would use LACP to aggregate the ports for interconnection between switches

Thanks!

Yes i was figuring STP will need to be enabled with the core set to root bridge but I was not sure whether to enable it on the edges. My assumption was yes but we all know where those get us.

Hello all, this is my first post. I am getting back into networking after quite a while away from the game so go easy on me.

Our environment has 3 switches, Our core is a cisco SG-500-28p, the others are an HP v1910-48G, and a linksys SRW2024p.

I want to know the best way to connect these switches for redundancy and speed if possible. I realize that may be 2 different answers.

I will also need to know if spanning tree protocol will need to be used vs LACP ect for the best solution because I am very new to using those.

I am attaching a document to show some examples but they will basically be variations using the SFP ports or standard ports. Again these may not even make sense so go easy on me please.

The srw2024 has 2, 1 gigabit SFP ports

The sg500-28p has 4, 10gig SFP ports

The V1910-48G has 4, 1gig SFP ports

I am only assuming here but I believe the speed can be set or will auto negotiate down on the SG500 SFP ports

Would there be an advantage to using the SFP ports vs a pair of standard aggregated LACP ports? Both the SFP and standard ports are 1 gigabit.

Take a look at my crude drawings, please show me what I missed and what I clearly do not understand so that I can make this work.
