Parameters
diameter: Specifies the switched network diameter, ranging from 2 to 7.
Description
Use the stp bridge-diameter command to specify the network diameter, 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 and you can set the timers by setting the network
diameter. With the network diameter set to 7 (the default), the three timers will be set to their defaults.
In STP, RSTP, or MSTP mode, each MST region is considered as a device, and the configured network
diameter of the switched network is only effective for the CIST (or the common root bridge), not for MSTIs.
Related commands: stp timer forward-delay, stp timer hello, and stp timer max-age.
Examples
# In MSTP mode, set the network diameter of the switched network to 5.
