Description: When the device has become the new root of the Spanning Tree, this object decides whether to send a new root trap.
What is swL2DevAlarmNewRoot?
Determines whether the switch sends a newRoot trap when it becomes the new Spanning Tree root bridge. An admin enables this so the NMS is alerted whenever a topology event promotes this switch to root, which often signals an unplanned root bridge failure elsewhere.
Examples
