Configuring The Network Diameter Of A Switched Network - H3C S5500-EI series Operation Manual

Operation Manual – MSTP
H3C S5500-EI Series Ethernet Switches
Note:
A larger maximum hops setting means a larger size of the MST region. Only the
maximum hops configured on the regional root bridge can restrict the size of the MST
region.
II. Configuration example
# Set the maximum hops of the MST region to 30.
<Sysname> system-view
[Sysname] stp max-hops 30

1.3.6 Configuring the Network Diameter of a Switched Network

Any two stations in a switched network are interconnected through specific paths,
which are composed of a series of devices. Represented by the number of devices on a
path, the network diameter is the path that comprises more devices than any other
among these paths.
I. Configuration procedure
Follow these steps to configure the network diameter of the switched network:
Enter system view
Configure the network
diameter of the switched
network
Note:
Network diameter is a parameter that indicates network size. A bigger network
diameter represents a larger network size.
Based on the network diameter you configured, MSTP automatically sets an optimal
hello time, forward delay, and max age for the device.
The configured network diameter is effective for the CIST only, and not for MSTIs.
II. Configuration example
# Set the network diameter of the switched network to 6.
<Sysname> system-view
[Sysname] stp bridge-diameter 6
To do...
system-view
stp bridge-diameter
bridge-number
Use the command...
