Rapid Spanning Tree
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.
RSTP - System Configuration

User can view spanning tree information about the Root Bridge
 User can modify RSTP state. After modification, select button

RSTP mode:
user must enable or disable RSTP function before configuring 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, the 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 a
Spanning-Tree Protocol configuration message before attempting a reconfiguration.
Enter a value between 6 through 40

Hello Time (1-10): the time that the switch controls 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)
