Parameters
bridgenum: Network diameter to be set for a switched network. This argument ranges from 2 to 7.
Description
Use the stp bridge-diameter command to set the network diameter of a switched network. The
network diameter of a switched network is represented by the maximum possible number of switches
between any two terminal devices in a switched network.
Use the undo stp bridge-diameter command to restore the network diameter to the default value.
By default, the network diameter is 7.
After you configure the network diameter of a switched network, MSTP adjusts its hello time, forward
delay, and max age settings accordingly. With the network diameter set to the default value 7, the three
time-relate settings, including hello time, forward delay, and max age, are set to their default values as
well.
The stp bridge-diameter command only applies to CIST. It is invalid for MSTIs.
Related commands: stp timer forward-delay, stp timer hello, stp timer max-age.
