System Configuration
• User can view spanning tree information about the Root Bridge
• User can modify RSTP state. After modification, click Apply button
RSTP 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. If the value changes, user must
reboot the switch. 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
Rapid Spanning-Tree Protocol learning and listening states to the forwarding state. Enter
a value between 4 through 30
[NOTE]
1. Must 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)
2. Remember to execute the “Save Configuration” action, otherwise the new
configuration will lose when switch power off
