Figure 53: Definition of diameter and age
The diameter is the number of connections between the two devices furthest
away from the root bridge.
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.
As required, change and verify the settings and displays that relate
to each individual port (menu bar: Rapid Spanning Tree - Port).
