Assuming you meant an S series switch I would start withe the following:

Support-> show spantree stats

Support-> show spantree blockedports

Support-> show spantree debug port *.*.* active

Support-> show port operstatuscause

What model switch is this? and what version is it running? If it is an EXOS switch can you run "show stp " and copy the output?
