TREE

29-3

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)#
