Chapter 6 – Configuring Rapid Spanning Tree RSTP Concepts And Issues The 802.1d Spanning Tree Protocol was de veloped to allow the construction of robust networks that incor porate redundancy while pruning the active topology of the network to prevent loops. While ST P is effective, it requires that frame transfer must halt after a link outage un[...]

RuggedSwitch ™ User Guide There are three RSTP states: Disc arding, Learning and Forwardin g. The discarding state is entered when the port is first take n into service. The port does not learn addresses in this state and does not participate in frame t ransfer. The port looks for STP traffic in order to determine its role in the network. When it[...]

Chapter 6 – Configuring Rapid Spanning Tree Role There are four RSTP port roles: R oot, Designated, Alternate and Backup. If the bridge is designated (i.e. it is not the root bridge) it must have a single root port. The root port is the “best” (i.e. quickest) way to send traffic to the root bridge. A port is designated if it is the best port [...]

RuggedSwitch ™ User Guide Because an edge port services only end st ations, topology change messages are not generated when its link toggles. Point To Point and Multip oint Links RSTP uses a peer-peer protocol called Pr oposing-Agreeing to ensure transitioning in the event of a link failure. This protocol is point to point and breaks down in mult[...]

Chapter 6 – Configuring Rapid Spanning Tree IEEE 802.1d vs. IEEE 802.1w Costs The IEEE 802.1d specification limits port costs to value s of 1 to 65536.
