Parameters
•

ID of the MST instance (Range: 1- 7).
•
vlan-range—
VLANs to be added to or removed from the specified MST
instance. To specify a range of VLANs, use a hyphen. To specify a series of
VLANs, use a comma. (Range: 1-4094).
Default Configuration
VLANs are mapped to the common and internal spanning tree (CIST) instance
(instance 0).

User Guidelines
All VLANs that are not explicitly mapped to an MST instance are mapped to the
common and internal spanning tree (CIST) instance (instance 0) and cannot be
unmapped from the CIST.
For two or more devices to be in the same MST region, they must have the same
VLAN mapping, the same configuration revision number, and the same name.
