Section 9. Configuring the Spanning Tree Protocol The Spanning Tree Protocol (STP) provides tree topography for any arrangement of bridges. STP also provides a single 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 TP-Link device supports the following STP versions:  Classic STP - Provides a single path between end stations, avoiding and eliminating loops. For more information on configuring Classic STP, see Configuring the Classic STP.  Rapid STP - Detects and uses network topologies that provide faster convergence of the spanning tree, without creating forwarding loops. For more information on configuring Rapid STP, see Configuring the Rapid STP.  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 the Forwarding State in another STP instance. For more information on configuring Multiple STP, see Configuring the Multiple STP.

Conﬁguring the Spanning Tree Protocol

The Spanning

Tree

Protocol

(STP) provides tree topography for any arrangement of bridges. STP also provides a single

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 TP-Link device supports the following STP versions:

Classic STP

— Provides a single path between end stations, avoiding and eliminating loops.

For more information on conﬁguring Classic STP, see

Rapid STP

— Detects and uses network topologies that provide faster convergence of the spanning tree, without

creating forwarding loops.

For more information on conﬁguring Rapid STP, see

Conﬁguring the Rapid STP

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 the

Forwarding State

in another STP instance.

Deﬁning STP Properties

The

STP Properties Page

contains parameters for enabling STP on the device.

To deﬁne STP properties:

Click

System > Bridging Info > Spanning Tree > STP

> Properties

. The

STP Properties Page

opens:

Figure 84: STP Properties Page

The

STP Properties Page

contains the following ﬁelds:

Spanning Tree State

— Indicates whether STP is

enabled on the device. The possible ﬁeld values are:

–

Enable

— Enables STP on the device.

–

Disable

— Disables STP on the device.

STP Operation Mode

— Speciﬁes the STP mode that

is enabled on the device. The possible ﬁeld values are:

–

Classic STP

— Enables Classic STP on the device.

This is the default value.
