Mapping Secondary VLANs to Same MSTI as Primary VLANs for Private VLANs Configuring MST Procedure Step 1 Step 2 Step 3 Command or Action switch# configure terminal Purpose Enters configuration mode. switch(config)# spanning-tree mst Enters MST configuration submode. configuration switch(config-mst)# instance instance-id vlan vlan-range Maps VLANs to an MST instance, as follows: • For instance-id the range is from 1 to 4094. Instance 0 is reserved for the IST for each MST region. • For vlan-range the range is from 1 to 4094. When you map VLANs to an MSTI, the mapping is incremental, and the VLANs specified in the command are added to or removed from the VLANs that were previously mapped. Step 4 switch(config-mst)# no instance Deletes the specified instance and returns the VLANs to instance-id vlan vlan-range the default MSTI, which is the CIST. This example shows how to map VLAN 200 to MSTI 3: switch# configure terminal switch(config)# spanning-tree mst configuration switch(config-mst)# instance 3 vlan 200 Mapping Secondary VLANs to Same MSTI as Primary VLANs for Private VLANs When you are working with private VLANs on the system, all secondary VLANs must be in the same MSTI and their associated primary VLAN. Procedure Step 1 Step 2 Step 3 Command or Action switch# configure terminal switch(config)# spanning-tree mst configuration switch(config-mst)# private-vlan synchronize Purpose Enters configuration mode. Enters MST configuration submode. Automatically maps all secondary VLANs to the same MSTI and their associated primary VLAN for all private VLANs.
