Your switches will begin forwarding in approximately 6 seconds. You will only see the effects of this on switches with RSTP enabled. If you have some switches that do not have RSTP enabled they will not participate in the proposal/acknowledgement process. Do the switch that you will want to function as the root first and then work your way outwards. You'll want to plan on how many MST Instances you'll want to run. The name, revision number, and vlan mappings must match on each switch in order to be considered part of the same region. Be sure to place any ports connected to end stations in the edge role by entering spanning-tree admin-edge-port and then to protect from loops enter spanning-tree bpdu-protection.
I hate all Uppercase... I don't want my groups to seem angry at me all the time! =)
