set spantree backuproot

set spantree backuproot
Use this command to enable or disable the Spanning Tree backup root function on the switch.
Syntax
set spantree backuproot sid {disable | enable}
Parameters
sid
disable | enable
Defaults
None.
Mode
Switch command, read‐write.
Usage
The Spanning Tree backup root function is disabled by default on the D‐Series. When this feature
is enabled and the switch is directly connected to the root bridge, stale Spanning Tree information
is prevented from circulating if the root bridge is lost. If the root bridge is lost, 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:
D2(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.
