Stp Bpdu-Protection - H3C S5120-SI Series Command Reference Manual

Description
Use the region-level command to configure the MSTP revision level.
Use the undo region-level command to restore the default MSTP revision level.
By default, the MSTP revision level is 0.
Note that:
The MSTP revision level, the MST region name and the VLAN-to-instance mapping table of a
device jointly determine the MST region to which the device belongs. When the MST region name
and VLAN-to-instance mapping table are both the same for two MST regions, you can still tell them
apart by their MSTP revision levels.
After configuring this command, you need to run the active region-configuration command to
activate the configured MST region level.
Related commands:
region-configuration, check region-configuration, 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
