The bridge with the lowest bridge id becomes the root. You mentioned
below that you set the switch to the highest priority, hopefully this was
a typo. What's the priority of the current root bridge? The spanning
tree root primary command is a macro. (see previous) Maybe the priority
of the current root was set to a number lower than 100..
