command. And
then you can configure the parameters including region name, revision level, and VLAN
mapping table of the region.
Example

Parameter
instance instance-id
: Specifies the spanning tree instance ID, ranging from 0 to 16.
Specify it as 0 to configure the root bridge of CIST.
root primary
: Configure the current switch as the primary root of the designated STI.
bridge-diameter bridgenum
: Specify the network diameter of the spanning tree,
ranging from 2 to 7.
hello-time centi-senconds
: Specifies the Hello Time of the spanning tree, ranging from
100 to 1000 and measured in centiseconds.
Description
Using
stp root primary
command, you can configure the current switch as the primary
root of the designated STI. Using
undo stp root
command, you can cancel the current
switch for the primary root of the designated STI.
By default, the switch does not server as a root bridge.
You can configure a root bridge for every STI without concerning the switch priority.
When configuring the root bridge, you may also specify the network diameter of the
designated switching network, so that the switch will calculate and get three time
parameter values (Hello time, Forward Delay and Max Age). The Hello time got in this
way may not be as good as expected. You can specify the
hello-time centi-senconds
parameter to overwrite it. Normally, you are recommended to set the network diameter
to get the other two time parameter of the switch accordingly.
