Table 5-62 Spanning Tree Commands
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.
