revision-level
Syntax
revision-level level
undo revision-level
View
MST region view
Default level
2: System level
Parameters
level: Specifies an MSTP revision level, in the range of 0 to 65535.
Description
Use revision-level to configure the MSTP revision level.
Use undo revision-level to restore the default MSTP revision level.
By default, the MSTP revision level is 0.
The MSTP revision level, the MST region name, and the VLAN-to-instance mapping table of a device determine the device's MST region. When the MST region name and VLAN-to-instance mapping table are both the same for two MST regions, they can still be differentiated by their MSTP revision levels.
After configuring this command, run the active region-configuration command to activate the configured MST region level.
Related commands: instance, region-name, vlan-mapping modulo, display stp region-configuration, check region-configuration, and active region-configuration.
Examples
# Set the MSTP revision level of the MST region to 5.
<Sysname> system-view [Sysname] stp region-configuration [Sysname-mst-region] revision-level 5
