Configuring Spanning Tree
Spanning Tree Protocol (STP) provides tree topography for any arrangement of bridges, as well as providing a single path
between end stations on a network, thus eliminating loops.
Loops occur when alternate routes exist between hosts. Loops in an extended network can cause bridges to forward traffic
indefinitely, resulting in increased traffic and reducing network efficiency.
The device supports the following STP versions:
Version Description
Classic STP
Provides a single path between end stations, preventing loops from occurring.
Rapid STP
Detects and uses network topologies that provide faster convergence of the spanning tree,
without creating forwarding loops.
Multiple STP
Provides various load balancing scenarios. For example, if port A is blocked in one STP
instance, the same port can be placed in Forwarding State in another STP instance.
The STP Bridge Global Settings Page contains parameters for enabling STP on the device. This section contains the
