Spanning Tree
The Spanning Tree Protocol (STP) 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 (i.e., an STP-compliant switch, bridge, or router) in your network to ensure that only one route exists
between any two stations on the network, and provide backup links that automatically take over when a primary link goes down.
The Spanning Tree Protocols supported by the switch include the following standards:
l STP Spanning Tree Protocol (IEEE 802.1D)
l RSTP Rapid STP (IEEE 802.1w)
RSTP is designed as a general replacement for the slower, legacy STP. RSTP achieves much faster reconfiguration (around one tenth of that required by STP)
by reducing the number of state changes before active ports start learning, predefining an alternate route that can be used when a node or port fails, and
retaining the forwarding database for ports insensitive to changes in the tree structure when reconfiguration occurs.
The Spanning Tree page contains links to pages that allow you to specify the parameters of the Spanning Tree Protocol:
l Bridge Settings
l Advanced Bridge Settings
l Port Settings
l Trunk Settings
