6.6.2 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.

6.6.2.1 STP System Configuration
User can view spanning tree information about the Root Bridge
User can modify RSTP state. After modification, click
Apply
button
Mode:
user 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.
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 Rapid Spanning-Tree Protocol learning and listening states
to the forwarding state. Enter a value between 4 through 30
[NOTE]
Follow the rule to configure the MAX Age, Hello Time, and Forward
Delay Time.
2 x (Forward Delay Time value –1) > = Max Age value >= 2 x (Hello Time
value +1)
