instance (MST)
Use
instance
MST Configuration mode command to map VLANs to an MST
instance. Use the

instance
instance-id
vlan
vlan-range
no instance
instance-id
vlan
vlan-range
Parameters
•
instance-id
—MST instance (Range: 1–15)
•
vlan-range
—The specified range of VLANs is added to the existing ones.
To specify a range, use a hyphen. To specify a series, use a comma. (Range:
1–4094)
Default Configuration
All VLANs are mapped to the common and internal spanning tree (CIST)
instance (instance 0).
Command Mode
MST Configuration mode
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.
Example
The following example maps VLANs 10-20 to MST instance 1.
Console(config)#
spanning-tree mst configuration
