4.15 RSTP Configuration
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.
4.15.1 System Configuration
1. You can view spanning tree information about the Root Bridge.
2. You can modify RSTP state. After modification, click button.
RSTP mode: you must enable or disable RSTP function before configure the related
parameters.
Priority (0-61440): a value used to identify the root bridge. The bridge with the lowest value
has the highest priority and is selected as the root. If you change the value, you must reboot
the switch assign path priority number. The value must be multiple of 4096 according to the
protocol standard rule.
Max Age (6-40): the number of seconds a bridge 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 switch sends 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
