Command Manual – MSTP
H3C S7500E Series Ethernet Switches
Description
Use the region-level command to configure the MSTP revision level of your device.
Use the undo region-level command to restore the default MSTP revision level.
The MSTP revision level, the MST region name and the VLAN-to-instance mapping
table of a device jointly determine the MST region the device belongs to.

undo stp
View
System view, Ethernet interface view, port group view
Parameters
enable: Enables the MSTP feature.
disable: Disables the MSTP feature.
Description
Use the stp command to enable or disable the MSTP feature globally or on the port(s).
Use the undo stp command to restore the default MSTP status.
By default, MSTP is globally disabled.
MSTP is disabled on ports by default and automatically enabled on all ports when it is
enabled globally on the device.
Note that:
To control MSTP flexibly, you can disable the MSTP feature for certain ports so
that they will not take part in spanning tree calculation and thus to save the
device's CPU resources.
