The unacknowledgedTCN notification is generated when a TCN sent towards the root bridge on the root port (SAP or SDP binding) has not been acknowledged within the allowed time. A portion of the spanning tree topology may not have been notified that a topology change has taken place. FDB tables on some devices may take significantly longer to represent the new distribution of layer-2 addresses. Examine this device and devices towards the root bridge for STP issues.
