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