RE: FW: Spanning tree Protocols Questions [7:36565]
Hi, Hope this helps, Q1: Your statement is correct. A port must still listen to BPDUs in order to detect topology changes. Q2: According to Cisco books, blocked, listening, learning, and forwarding are valid STP stages. I haven't seen a book not list blocking. If you have one handy, let me know. Q3: I interpret BPDUs as a generic term to represent Topology and Configuration BPDUs.

FW: Spanning tree Protocols Questions [7:36565]
Question (1) Is the first part of this statement correct? I have looked at the 801d paper for an answer but I am still uncertain. "In blocking mode, an interface will receive and send BPDUs but not send and receive data traffic. " Question (2) Are blocked port considered part of the spanning tree? When I do a "show span" on switches, I do see the blocked port listed but on testing material I have seen both answers: one reference says blocked ports are part of the spanning tree another says they are not. Which one is true? Question (3) What is the difference between a BPDU and a Configuration BPDU? Is it right to say that configuration BPDUs are sent only by the root bridge and that BPDUs are fowarded by non-root bridges?
