I have recently started a new job, so have inherited a network. I have attached the network topology that I have inherited (link at bottom of post).
Switches 1, 2 and 3 are in the same building. Switch 4 is in a different building connected by fibre (about 20 meters away so not far). All switches have 1gb fibre sfp's that connected them together. There is physically a fibre connect between switch 1 (Port 52) and switch 2 (port 51) but have no connectivity lights.
Switches 1, 2 and 4 are Cisco Catalyst 2960S
Switch 3 is a Cisco Catalyst 2960x
My question(s) is, is this the best setup for a 4 switch network? Should I enable to link between switch 1 and 2 if it isn't already and how would I do it if I need to?
