GE-DSH-73/DSH-82 and DSH-82-PoE User Manual 91
A port transitions from one state to another as follows:
• From initialization (switch boot) to blocking.
• From blocking to listening or to disabled.
• From listening to learning or to disabled.
• From learning to forwarding or to disabled.
• From forwarding to disabled.
• From disabled to blocking.
Figure 5-38: 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.
