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.

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)#
(Continued)
Function
Configures the spanning tree priority of an interface
Prevents a designated port from passing superior BPDUs
Disables spanning tree for an interface
Stops propagation of topology change information
Re-checks the appropriate BPDU format
Shows spanning tree configuration for the common
spanning tree (i.e., overall bridge), a selected interface, or
an instance within the multiple spanning tree
Shows the multiple spanning tree configuration
