802.1W — Cisco CCNA (200-301) Practice Questions

IEEE 802.1w defines Rapid Spanning Tree Protocol (RSTP), an evolution of the original 802.1D STP standard designed to dramatically reduce convergence time from up to 50 seconds down to a few seconds or less. The 802.1w standard introduced new port roles such as alternate and backup ports and refined the negotiation process between switches to speed up topology recalculation. For the CCNA exam, understanding 802.1w is important because modern Cisco switches run RSTP by default, and candidates must recognize the differences between 802.1D and 802.1w in terms of port roles, port states, and convergence behavior.
