notification
A mstpTopologyChange trap is sent by a bridge when any of its configured ports n any instance (CIST or MSTI) transitions from the Learning state to the Forwarding state, or from the Forwarding state to the Blocking state. The trap is not sent if a mstpNewRootBridge trap is sent for the same transition. Implementation of this trap is optional.
