STP is making a mess of my network

[chrissolo88]

I installed redundant link between my switches and set up port channels and everything was working fine at first then stp started blocking host ports and not effectivley utilizing the port channels like it should

Switch 1 which goes out to the edge router and down to switch 2 and 3

really confused on this one 

[chrissolo88]

It came down to a speed mismatch on one interface its all working well again thanks everyone for the input

Hello

glad you got it sorted just like to highlight if you still don’t have a definitive specified stp root suggest you make the necessary changes to establish one as best practice
