State 
Enables STP or RSTP for the bridge (i.e. on all ports).  Note that STP/RSTP can 
be disabled on a per port basis in the Port RSTP Parameters menu.   
Version Support 
Selects the versions of STP to support, either STP or STP and Rapid STP.  
Bridge Priority 
The Bridge Priority provides a way to control the topology of the STP connected 
network.  The bridge with the lowest priority will become root.  The desired Root 
and Designated bridges can be configured for a particular topology.  In the event 
of a failure of the root bridge, the bridge with the next lowest priority will then 
become root.  Designated bridges that (for redundancy purposes) service a 
common LAN also use priority to determine which bridge is active.  In this way 
careful selection of Bridge Priorities can establish the path of traffic flows in 
normal and abnormal conditions.
