Command Line Interface

spanning-tree

This command enables the Spanning Tree Algorithm globally for the switch. Use the no form to disable it.

Syntax

[no] spanning-tree

Default Setting

Spanning tree is enabled.

Command Mode

Global Configuration

Command Usage

The Spanning Tree Algorithm (STA) can be used to detect and disable network loops, and to provide backup links between switches, bridges or routers. This allows the switch to interact with other bridging devices (that is, an STA-compliant switch, bridge or router) in your network to ensure that only one route exists between any two stations on the network, and provide backup links which automatically take over when a primary link goes down.

Example

This example shows how to enable the Spanning Tree Algorithm for the switch:

Console(config)#spanning-tree

Console(config)#

spanning-tree mode

This command selects the spanning tree mode for this switch. Use the no form to restore the default.

Syntax

spanning-tree mode {stp rstp} no spanning-tree mode

stp - Spanning Tree Protocol (IEEE 802.1D)

rstp - Rapid Spanning Tree Protocol (IEEE 802.1w)

Default Setting

rstp

Command Mode

Global Configuration

Command Usage

Spanning Tree Protocol

Uses RSTP for the internal state machine, but sends only 802.1D BPDUs.
