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
