• From forwarding to disabled
• From disabled to blocking
Figure 5-3. STP Port State Transitions
When STP is enabled, 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.
