83Rapid Spanning TreeThe Rapid Spanning Tree Protocol (RSTP) is an evolution of the Spanning Tree Protocoland provides for faster spanning tree convergence after a topology change. The systemalso supports STP and the system will auto detect the connected device that is runningSTP or RSTP protocol.RSTP - System Configuration User can view spanning tree information about the Root Bridge. User can modify RSTP state. After modification, clickApply button RSTP mode: User must enable or disable RSTP function before configure therelated parameters. Priority (0-61440): A value used to identify the root bridge. The bridge with thelowest value has the highest priority and is selected as the root. The value mustbe a multiple of 4096 according to the protocol standard rule. Max Age (6-40): The number of seconds a bridge waits without receivingSpanning-tree Protocol configuration messages before attempting areconfiguration. Enter a value between 6 through 40. Hello Time (1-10): The time that controls switch sends out the BPDU packet tocheck RSTP current status. Enter a value between 1 through 10. Forward Delay Time (4-30): The number of seconds a port waits beforechanging from its Rapid Spanning-Tree Protocol learning and listening to STPstates to the forwarding state. Enter a value between 4 through 30.Note Follow the rule to configure the MAX Age, Hello Time, and Forward DelayTime.2 x (Forward Delay Time value – 1) > = Max Age value >= 2 x (HelloTime value +1)
