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.
6.19.1 RSTP System Configuration
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
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.
[NOTE]
Follow the rule as below 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)
