Spanning Tree Commands
This section includes commands that configure the Spanning Tree Algorithm (STA)
globally for the switch, and commands that configure STA for the selected 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,
