Switch(config-mst)# instance 2 vlans 1-100
Switch(config-mst)#
This example shows how to map a VLAN to instance 5:
Switch(config-mst)# instance 5 vlans 1100
Switch(config-mst)#
This 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)#
This 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)#
