Rapid Spanning Tree
If required, change the values for "Hello Time", "Forward Delay" and
"Max. Age" in the root Switch. The root Switch then transfers this
data to the other Switches. The dialog displays the data received
from the root Switch in the left column. In the right column you enter
the values which shall apply when this Switch becomes a root
Switch. For the configuration, take note of
Figure 52: Assigning Hello Time, Forward Delay und Max. Age
The times entered in the RSTP dialog are in units of 1 s.
Example: Hello Time = 2 corresponds to 2 seconds.
