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.
SUMMARY STEPS
1. switch# configure terminal
2. switch(config)# spanning-tree mst configuration
3. switch(config-mst)# private-vlan synchronize
Mapping Secondary VLANs to Same MSTI as Primary VLANs for Private VLANs
Purpose
Enters configuration mode.
Enters MST configuration submode.
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.
Deletes the specified instance and returns the VLANs to the default
MSTI, which is the CIST.
