Command Manual – MSTP
H3C S7500E Series Ethernet Switches
If you specify no VLAN in the undo instance command, all VLANs mapped to the
specified spanning tree instance will be remapped to the CIST.
You cannot map the same VLAN to different spanning tree instances. If you map a
VLAN that has been mapped to an instance to a new instance, the old mapping
will be automatically removed.

Description
Use the region-name command to configure the MST region name of your device.
Use the undo region-name command to restore the default MST region name.

level of a device jointly determine the MST region the device belongs to.
