STP is a protocol which is a set of rules for operation.
I understand your point bu,t that is why Cisco is always working on
standardizing all of their platforms on IOS to have a very common set of
operating parameters to have the best interoperability.
The macro should give you the result of setting the root bridge in the
network even if you have a mixed environment.

Re: STP Clarification
I'm familiar with the commands, but my point is I think this is only
predictable in a world where you have for example all 3550's running the
same code, that recognize the ext system id. I think if you have perhaps
a router, running spanning tree, it's possible this command may not
suffice, and you may be forced to manually set the priority to a lower
value, versus using the macro. Slap me if I'm wrong.
Thanks.
