4.6.1 Spanning Tree
1. Spanning Tree Protocol
The IEEE 802.1D Spanning Tree Protocol and IEEE 802.1W Rapid Spanning Tree Protocol allow for the blocking
of links between switches that form loops within the network. When multiple links between switches are detected,
a primary link is established. Duplicated links are blocked from use and become standby links. The protocol allows
for the duplicate links to be used in the event of a failure of the primary link. Once the Spanning Tree Protocol is
configured and enabled, primary links are established and duplicated links are blocked automatically. The
reactivation of the blocked links (at the time of a primary link failure) is also accomplished automatically without
operator intervention.
This automatic network reconfiguration provides maximum uptime to network users. However, the concepts of the
Spanning Tree Algorithm and protocol are a complicated and complex subject and must be fully researched and
understood. It is possible to cause serious degradation of the performance of the network if the Spanning Tree is
incorrectly configured. Please read the following before making any changes from the default values.
The Switch STP performs the following functions:
