Default Level
2: System level
Parameters
diameter: Specifies the switched network diameter, in the range of 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.
Note that:
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 three
timers indirectly by setting the network diameter. Based on the network diameter you configured,
MSTP automatically sets an optimal hello time, forward delay, and max age for the device. With the
network diameter set to 7 (the default), the three timer are also set to their defaults.
This configuration must be configured on the root bridge and is effective for the CIST only, not for
MSTIs.
Related commands: stp timer forward-delay, stp timer hello, stp timer max-age.
Examples
# Set the network diameter of the switched network to 5.
