CCNA R&S Question of the Week: Rapid STP

Which port state is listed as a Rapid STP (Spanning Tree Protocol) state?

A. Learning
B. Listening
C. Discarding
D. Forwarding

Reveal Answer

Answer: C.

Rapid STP has three port states, discarding, learning and forwarding, while traditional STP (which is what IOS switches default to) has five port states, blocking, listening, learning, forwarding and disabled. So discarding is the replacement of blocking and is the new port state in Rapid STP.
