The network diameter refers to the maximum count of switches on the path between
any two terminal devices.
The definition of network diameter: Maximum count of switches between the farthest
communication ends.
stp bridge-diameter command configures the switching network diameter and
determines the three time parameters of MSTP accordingly. This configuration takes
effect on CIST only but makes no sense for MSTI.
The spanning tree convergence can be speeded up, when Hello Time, Forward Delay,
and Max Age are well configured. These parameters are related to the network scale.
You can configure the network scale to get the time parameters. Upon the
user-configured bridge-diameter parameter, MSTP will automatically set Hello Time,
Forward Delay, and Max Age to moderate values. When bridge-diameter defaults to 7,
the time parameters also take their respective default values.
For the related command, see stp timer forward-delay, stp timer hello, stp timer
max-age.
Example
# Set the diameter of the switching network to 5.
[Quidway] stp bridge-diameter 5
1.1.12 stp bridge-priority
Syntax
stp [ instance instance-id ] bridge-priority priority
undo stp [ instance instance-id ] bridge-priority
View
System view
Parameter
instance-id: Specifies the spanning tree instance ID, ranging from 0 to 16, instance 0 is
CIST.
priority: Specifies the switch priority, ranging from 0 to 61440 with a step length of 4096.
That is, 16 priorities are available for the switch including 0, 4096, 8192, etc. By default,
the switch priority is 32768.
Description
Using stp bridge-priority command, you can configure the bridge priority in the
specified STI. Using undo stp bridge-priority command, you can restore the default
value of bridge priority .
