6.2.1.66 set spantree backuproot
Use this command to enable or disable the Spanning Tree backup root function. 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.
