Spanning-Tree Commands

instance (mst)

The instance MST Configuration mode command maps VLANS to an MST instance.

Syntax

instance instance-id{add remove} vlan vlan-range

Parameters

instance-ID—ID of the MST instance (Range: 1-15).

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).

Command Modes

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

Console(config-mst)# instance 1 add vlan 10-20
