Configuring The Network Diameter Of A Switched Network - H3C S3610-28P Operation Manual

Operation Manual – MSTP
H3C S3610&S5510 Series Ethernet Switches
When a device becomes the root bridge of the CIST or MSTI of an MST region , the
maximum hop in the configuration BPDUs generated by this device defines the network
diameter of the spanning tree to define how far the spanning tree can reach in this MST
region. All the devices other than the root bridge in the MST region use the maximum
hop value set for the root bridge.
I. Configuration procedure
Follow these steps to configure the maximum number of hops of the MST region:
Enter system view
Configure the maximum
hops of the MST region
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:
