To map a VLAN or a set of VLANs to an MST instance, use the instance command. To return the
VLANs to the common instance default, use the no form of this command.
Syntax Description

vlans vlan-range
Command Default
Mapping is disabled.
Command Modes MST configuration mode
Command History Release

Usage Guidelines
The mapping is incremental, not absolute. When you enter a range of VLANs, this range is added or
removed to the existing ones.
Any unmapped VLAN is mapped to the CIST instance.
Examples The following example shows how to map a range of VLANs to instance 2:
Switch(config-mst)# instance 2 vlans 1-100
Switch(config-mst)#
The following example shows how to map a VLAN to instance 5:
Switch(config-mst)# instance 5 vlans 1100
Switch(config-mst)#
The following example shows how to move a range of VLANs from instance 2 to the CIST instance:
Switch(config-mst)# no instance 2 vlans 40-60
Switch(config-mst)#
The following example shows how to move all the VLANs mapped to instance 2 back to the CIST
instance:
Switch(config-mst)# no instance 2
Switch(config-mst)#
