configuration
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.

Function
Configures loopback release mode for a port
Enables BPDU loopback SNMP trap notification for a port
Configures the path cost of an instance in the MST
Configures the priority of an instance in the MST
Floods BPDUs to other ports when global spanning tree is
disabled
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
Manually releases a port placed in discarding state by
loopback-detection
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
