Usage guidelines
An appropriate setting of hello time, forward delay, and max age can speed up network convergence.
The values of these timers are related to the network size, and you can set the timers by setting the
network diameter. With the network diameter set to 7 (the default), the three timers will also be set to
their defaults.
Each MST region is considered as a device, and the configured network diameter of the switched
network takes effect only on the CIST (or the common root bridge), not on other MSTIs.
Examples
# In MSTP mode, set the network diameter of the switched network to 5.
