Configuring Spanning Tree

The

Spanning Tree Protocol

(STP) provides tree topography for any arrangement

of bridges. STP also provides one path between end stations on a network,
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 Spanning Tree versions:

•

Classic STP

— Provides a single path between end stations, avoiding and

eliminating loops.

•

Rapid STP

— Detects and uses network topologies that provide faster

convergence of the spanning tree, without creating forwarding loops.

•

Multiple STP

— Provides full connectivity for packets allocated to any VLAN.

Multiple STP is based on the RSTP. In addition, Multiple STP transmits packets
assigned to different VLANs through different MST regions. MST regions act as
a single bridge.

Defining Spanning Tree

The Spanning Tree section contains the following topics:

•

Defining STP Properties

•

Defining Spanning Tree Interface Settings

•

Defining Rapid Spanning Tree

Defining STP Properties

The

STP Properties Page

contains parameters for enabling STP on the device.

The

STP Properties Page

is divided into three areas, Global Settings, Bridge

Settings. and Designated Root.
