Parameters
diameter: Specifies the switched network diameter, ranging from 2 to 7.
Description
Use the stp bridge-diameter command to specify the network diameter, namely the maximum possible
number of stations between any two terminal devices on the switched network.
Use the undo stp bridge-diameter command to restore the default.
By default, the network diameter of the switched network is 7.
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. You can set these timers by setting the network
diameter. With the network diameter set to 7 (the default), the three timers will be set to their defaults.
