I do understand spanning tree but there is a but of confusion in the logs. Right now I am busy with optaining my ccnp switch, route and Tshoot but I've got my mind stuck on the output below about Fastethernet fa0/19.
When I enter the debug spanning-tree all command it gives me the below info.
What you see on the output means that your switch is connected or is using a monitoring protocol as SPAN and is forwarding traffic by fa0/9. SPAN copies the traffic from a port of the switch to another switch that is connected to a network analyzer or monitoring device. Also copies traffic received, sent, or both, in ports or source VLANs to a destination port for analysis.
