Configure basic STP functions, including:
(1) Configure the STP mode for the ring network.
(2) Configure primary and secondary root bridges.
(3) Set path costs for ports to block certain ports.
(4) Enable STP to eliminate loops.
NOTE
STP is not required on the interfaces connected to terminals because these interfaces do not
need to participate in STP calculation.
