Spanning Tree Change

It has been detected that the spanning tree port state on this interface has changed from the old port state to a new port state. Possible Causes: 1. The port state has changed to blocking to prevent a loop. A new device may have been added to the network. 2. The port state has changed to listening/learning because the spanning tree has been turned on or the former root bridge is no longer available and is completing convergence.
