4-6.16 Rapid Spanning Tree Protocol Configuration (RSTP)
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. HME-421E/423E also supports STP and will auto
detect the connected device whether it is running STP or RSTP protocol.
4-6.16.1 System Configuration
The administrator can view the spanning tree information from the Root Bridge Information column.
RSTP Mode
This feature allows the administrator to enable or disable the RSTP
function. The parameters will be available for configuration after the
RSTP function is enabled.
Priority (0-61440)
This is the value used to identify the root bridge. The bridge with the
lowest value has the highest priority and will be selected as the root. If
this value has been changed, the switch must be rebooted for the new
settings to be in effect. The value must be multiple of 4096 according to
the protocol standard.
Max Age (6-40)
This value is the seconds a bridge waits for without receiving spanning
tree messages before attempting to reconfigure. Enter a value between 6
and 40.
Hello Time (1-10)
This value is the time in seconds that controls when the switch sends out
the BPDU packet to check RSTP current status. Enter a value between 1
and 10.
Forward Delay Time
(4-30)
This value is the time in seconds a port waits for before changing its
Rapid Spanning Tree protocol learning and listening state to the
forwarding state. Enter a value between 4 and 30.
After finishing necessary configurations, click on Apply to save the settings.
The administrator 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).
