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 | mstp}
no spanning-tree mode
• stp - Spanning Tree Protocol (IEEE 802.1D)
• rstp - Rapid Spanning Tree Protocol (IEEE 802.1w)
• mstp - Multiple Spanning Tree (IEEE 802.1s)
