GS748T Software User Manual
The GS748T switch supports Rapid Spanning Tree Protocol (defined by IEEE 802.1w), which is an improvement (over the 802.1D STP) that shortens connection latency between nodes. The resultant path between nodes determined by RSTP is the same as that eventually determined by STP. The following concepts are associated with this protocol.
•Fast Link: When a port running the standard Spanning Tree Protocol (STP) is connected, it will go through the STP negotiation (listening
•Bridge Priority: Priority setting of this switch in the Spanning Tree.
•Bridge Max Age: Amount of time before a configuration message is discarded by the system.
•Bridge Hello Time: Interval between configuration messages sent by the Spanning Tree algorithm.
•Bridge Forward Delay: Amount of time system spends in 'learning' and 'listening' states.
•Path Cost: The switch uses this to determine which port is the forwarding port. All other factors being equal, the path with the lowest cost to the root bridge is the active path.
•Path Priority: STP bases on this to determine the port to use for forwarding. The port with the lowest number has the highest priority.
The IEE 802.1W RSTP Setting page of the GS748T switch contains a set of default values which are optimal for most applications. Adjust these values if you must provide for special conditions.
