Figure 4-9-2: STP Port State Transitions
You can modify each port state by using management software. When you enable STP, every port on every switch in the
network goes through the blocking state and then transitions through the states of listening and learning at power up. If properly
configured, each port stabilizes to the forwarding or blocking state. No packets (except BPDUs) are forwarded from, or received
by, STP enabled ports until the forwarding state is enabled for that port.
