Rapid Spanning Tree Protocol

The Rapid Spanning Tree Protocol (RSTP) is an evolution of the Spanning Tree Protocol
and provides for faster spanning tree convergence after a topology change. The
system also supports STP and the system will auto-detect the connected device that
is running STP or RSTP protocol.
Theory
The Spanning Tree protocol can be used to detect and disable network loops, and to
provide backup links between switches, bridges or routers. This allows the switch to
interact with other bridging devices in your network to ensure that only one route
exists between any two stations on the network, and provide backup links, which
automatically take over when a primary link goes down. The spanning tree
algorithms supported by this switch include these versions:
• STP - Spanning Tree Protocol (IEEE 802.1D)
• RSTP - Rapid Spanning Tree Protocol (IEEE 802.1w)
The IEEE 802.1D Spanning Tree Protocol and IEEE 802.1W Rapid Spanning Tree
Protocol allow for the blocking of links between switches that form loops within the
network. When multiple links between switches are detected, a primary link is
established. Duplicated links are blocked from use and become standby links. The
