Figure 53: Definition of diameter and age
The network diameter is the number of connections between the two devices
furthest away from the root bridge.
Note: The parameters
– Forward Delay and
– Max Age
have a relationship to each other:
Forward Delay ≥ (Max Age/2) + 1
If you enter values that contradict this relationship, the device then
replaces these values with a default value or with the last valid values.
 When necessary, change and verify the settings and displays that
relate to each individual port (dialog: Rapid Spanning
Tree:Port).
