6.19 Rapid Spanning Tree

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.

6.19.1 RSTP System Configuration

•The user can view spanning tree information of Root Bridge.

• The user can modify RSTP state.After modification, click Apply .

>RSTP mode:The user must enable the RSTP function first before configuring the related parameters.

>Priority (0-61440): The switch with the lowest value has the highest priority and is selected as the root. If the value is changed, the user must reboot the switch.The value must be a multiple of 4096 according to the protocol standard rule.

>Max Age (6-40): The number of seconds a switch waits without receiving Spanning- tree Protocol configuration messages before attempting a reconfiguration. Enter a value between 6 through 40.

>Hello Time (1-10):The time that controls the switch to send out the BPDU packet to check RSTP current status. Enter a value between 1 through 10.

>Forward DelayTime (4-30):The number of seconds a port waits before changing from its Rapid Spanning-Tree Protocol learning and listening states to the forwarding state. Enter a value between 4 through 30.
