The IEEE 802.1D Spanning Tree Protocol resolves the problems of physical
loops in a network by establishing one primary path between any two switches
in a network. Any duplicate paths are barred from use and become standby or
blocked paths until the original path fails, at which point they can be brought
into service.

The switch meets the requirements of the Spanning Tree Protocol (STP) by
performing the following functions:
■ Creates a single spanning tree from any arrangement of switching or
bridging elements.

■ Compensates automatically for the failure, removal, or addition of any
device in an active data path.
■ Achieves port changes in short time intervals, which establishes a stable
active topology quickly with a minimum of network disturbance.
■ Uses a minimum amount of communications bandwidth to accomplish
the operation of the Spanning Tree Protocol.
■ Reconfigures the active topology in a manner that is transparent to
stations transmitting and receiving data packets.
■ Manages the topology in a consistent and reproducible manner through
the use of Spanning Tree Protocol parameters.
