Chapter 2 Catalyst 3560 Switch Cisco IOS Commands spanning-tree mst configuration When you map VLANs to an MST instance, the mapping is incremental, and VLANs specified in the command are added to or removed from the VLANs that were previously mapped. To specify a range, use a hyphen; for example, instance 1 vlan 1-63 maps VLANs 1 to 63 to MST instance 1. To specify a series, use a comma; for example, instance 1 vlan 10, 20, 30 maps VLANs 10, 20, and 30 to MST instance 1. 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 by using the no form of the command. For two or more switches to be in the same MST region, they must have the same VLAN mapping, the same configuration revision number, and the same name. Examples This example shows how to enter MST configuration mode, map VLANs 10 to 20 to MST instance 1, name the region region1, set the configuration revision to 1, display the pending configuration, apply the changes, and return to global configuration mode: Switch# spanning-tree mst configuration Switch(config-mst)# instance 1 vlan 10-20 Switch(config-mst)# name region1 Switch(config-mst)# revision 1 Switch(config-mst)# show pending Pending MST configuration Name [region1] Revision 1 Instance Vlans Mapped 0 1-9,21-4094 1 10-20 Switch(config-mst)# exit Switch(config)# This example shows how to add VLANs 1 to 100 to the ones already mapped (if any) to instance 2, to move VLANs 40 to 60 that were previously mapped to instance 2 to the CIST instance, to add VLAN 10 to instance 10, and to remove all the VLANs mapped to instance 2 and map them to the CIST instance: Switch(config-mst)# instance 2 vlan 1-100 Switch(config-mst)# no instance 2 vlan 40-60 Switch(config-mst)# instance 10 vlan 10 Switch(config-mst)# no instance 2 You can verify your settings by entering the show pending MST configuration command.
