In Rapid PVST+, which port state processes BPDUs but does not forward frames or update the MAC address table?

In Rapid PVST+, the blocking state receives BPDUs to monitor the network for topology changes but does not forward user data frames or learn MAC addresses. This prevents loops. The learning state processes BPDUs, learns MAC addresses, but still does not forward user frames. The listening state also processes BPDUs but does not learn MAC addresses or forward frames; it's an intermediary state before learning or forwarding. The disabled state means the port is administratively shut down and does not participate in STP or forward any traffic.
