Description
RSTP mode
Enables or disables RSTP mode.
Priority (0-61440)
A value used to identify the root bridge. The bridge with the lowest
priority is selected as the root. If more than one bridges have the
same priority, the one with the lowest MAC address will be
selected. If the value changes, you must reboot the switch. The
value must be a multiple of 4096 according to the protocol
standard rule
Max Age Time(6-40)
The number of seconds a bridge waits without receiving STP
configuration messages before attempting a reconfiguration. The
valid value is between 6 and 40.
Hello Time (1-10)
The time interval a switch sends out the BPDU packet to check
RSTP current status. The time is measured in seconds and the
valid value is between 1 and 10.
Forwarding Delay
Time (4-30)
The time of a port waits before changing from RSTP learning and
listening states to forwarding state. The valid value is between 4
and 30.
Apply
Click to apply the configurations.
NOTE
: the calculation of the MAX Age, Hello Time, and Forward Delay Time is as follows:
2 x (Forward Delay Time value –1) > = Max Age value >= 2 x (Hello Time value +1)
The following pages show the information of the root bridge, including its port status.
