Gary,
I just sent you an email with an attached document, as I have been assigned your GTAC case that you opened up earlier today.
I am going to go ahead and paste the output of the section related to STP / PVST+ in the Extreme / Cisco doc that I attached for the completeness of this HUB conversation.
