Platform Description
-
spanning-tree
This command is used to enable MSTP and configure its basic settings globally. The no option
of the command disables the spanning-tree function. The no option of the command with
parameters only restores the corresponding parameters to the default values, but does not
disable the spanning-tree function.
spanning-tree [ forward-time seconds | hello-time seconds | max-age seconds ]
no spanning-tree [ forward-time | hello-time | max-age ]
Parameter
Description

Description
forward-time seconds
Interval at which the port status changes
hello-time seconds
Interval at which the device sends the BPDU message
max-age seconds
Maximum aging time of the BPDU message
Defaults
Disabled
Command Mode
Global configuration mode
Usage Guide
The values of forward-time, hello time and max-age are interrelated. Modifying one of
these three parameters will affect the others. There is a restricted relationship among the
above three values as shown below:
2*(Hello Time+1.0snd) <= Max-Age Time <= 2*(Forward-Delay–1.0snd)
If the values do not meet the condition, the settings will fail.
Configuration
Examples
Example 1: Enable the spanning-tree function:
Ruijie(config)# spanning-tree
Example 2: Configure the BridgeForwardDelay:
Ruijie(config)# spanning-tree forward-time 10
