A network engineer observes that a switch port in a Rapid PVST+ network is not forwarding frames but is still processing BPDUs. Which port state is this port in?
Disabled state
Forwarding state
Blocking state
Learning state
In Rapid Per-VLAN Spanning Tree Plus (Rapid PVST+), a port in the blocking state does not forward data frames or learn MAC addresses but continues to receive and process Bridge Protocol Data Units (BPDUs). This state prevents bridging loops by ensuring that redundant paths are blocked until needed. The forwarding state allows a port to send and receive data frames and learn MAC addresses. The learning state allows a port to learn MAC addresses but does not forward data frames, preparing the port to transition to forwarding. The disabled state is when a port is administratively shut down and does not participate in the Spanning Tree process or forward frames.
