When the switch powers up, or when a device is connected to a port, the port enters the spanning tree listening state. When the Forward Delay timer expires, the port enters the learning state. When the Forward Delay timer expires a second time, the port is transitioned to the forwarding or blocking state.
In the "BCMSN 642-811.pdf" chapter 9 picture 9-1 said that:
When the switch powers up, the spanning tree blocking state
My Question is : Which is correct? and Why
