I have 3 stacks of access switches (all FCX648), each in different locations (different floors). Right now switch 3 is connected to switch 2, and switch 2 is connected to switch 1 (using 10Gb fiber XFP). I want to introduce a new connection between switch 3 and switch 1 for redundancy.
Should I just plug this in and let it go, or should I configure something to so it knows that my interconnects are uplinks. I want to prevent any kind of confusion to the network equipment.
Thanks in advance :)

OK, after some more research, it looks like I need to have 1 switch set as the root bridge by it having the highest priority.
I have RSTP turned on and my switch 1 has the priority set to the highest priority (lowest number) between the 3 switches (while in enable and config mode, I typed in,...
spanning-tree priority 1000
I think I am good, unless someone else sees a flow in my logic :)
