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.
