Set Spantree Backuproot; Clear Spantree Backuproot - Enterasys Matrix DFE-Gold Series Configuration Manual

Configuring Spanning Tree Bridge Parameters

set spantree backuproot

Use this command to enable or disable the Spanning Tree backup root function.
Syntax
set spantree backuproot sid {enable | disable}
Parameters
sid
enable | disable
Defaults
None.
Mode
Switch command, Read‐Write.
Usage
Enabled by default on bridge(s) directly connected to the root bridge, this prevents stale Spanning
Tree information from circulating in the event the root bridge is lost. If this happens, the backup
root will dynamically lower its bridge priority so that it will be selected as the new root over the
lost root bridge.
Example
This example shows how to enable the backup root function on SID 2:
Matrix(rw)->set spantree backuproot 2 enable

clear spantree backuproot

Use this command to reset the Spanning Tree backup root function to the default state of disabled.
Syntax
clear spantree backuproot sid
Parameters
sid
Defaults
None.
Mode
Switch command, Read‐Write.
