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.
The user can view spanning tree information of Root Bridge. •
The user can modify RSTP state. After modification, click . •
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 Delay Time (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.
