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:

Create a single Spanning Tree from any arrangement of switching or bridging elements. 

Compensate automatically for the failure, removal, or addition of any device in an active data 
path.

Achieve port changes in short time intervals, which establishes a stable active topology quickly 
with a minimum of network disturbance.

Use a minimum amount of communications bandwidth to accomplish the operation of the 
Spanning Tree Protocol.

Reconfigure the active topology in a manner that is transparent to stations transmitting and 
receiving data packets.

Manage the topology in a consistent and reproducible manner through the use of Spanning Tree 
Protocol parameters.

NOTE: The term “switch” is used as an equivalent to “bridge” in this document.
