1.1.11 stp bridge-diameter
Syntax
stp bridge-diameter bridgenum
undo stp bridge-diameter
View
System view
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 terminals in a switched network.
Use the undo stp bridge-diameter command to revert to the default network diameter.
By default, the maximum number of switches between any two terminal devices in the
switched network is 7.
The network diameter parameter is represented by the maximum number of switches
between two communication ends.
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 7 (the default), the three time-relate settings, Hello time, Forward delay, and Max age,
are set to their defaults 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.
Examples
# Set the network diameter to 5.
