Explanation

Rapid-PVST (and RSTP/802.1w) introduces the 'discarding' port state, which is new compared to classic 802.1D STP. In classic STP, ports cycle through disabled, blocking, listening, learning, and forwarding states. RSTP/Rapid-PVST consolidates the disabled, blocking, and listening states into a single 'discarding' state. This reduces the number of port states to just three: discarding, learning, and forwarding. The 'discarding' state is the key new concept - ports in this state do not forward data frames and do not learn MAC addresses.
