High rate of stp topology changes on port 8
WebMar 11, 2024 · An STP topology change occurs when a switch moves a port to the forwarding state or when a forwarding or learning state port is sent to the blocking state. The process of a topology change is as follows: The switch that detects the change sends a special message known as a TCN (Topology Change Notification). TCNs are sent through … WebOnce the topology change notification reaches the root bridge it will set the TC (topology change) bit in the BPDUs it will send. These BPDUs will be forwarded to all the other …

WebDec 14, 2024 · This indicates that the Spanning Tree process is now aware that Gi0/2 is down, and that a topology change has occurred. Just like the debug on the fourth line of the first event, this debug logically separates each part of the BPDU to make it easier to read. In this debug, the third section is set to 0x80. This indicates that this is a Topology ... WebIn the topology described in the first diagram, there are only two different final logical topologies, so only two spanning tree instances are really necessary. There is no need to run 1000 instances. If you map half of the 1000 VLANs to a different spanning tree instance, as shown in this diagram, these statements are true:
