private-vlan synchronize

To map the secondary VLANs to the same instance as the primary VLAN, use the private-vlan
synchronize command in MST configuration submode.
Syntax Description This command has no arguments or keywords.

The secondary VLANs are not mapped to the same instance as the primary VLAN.
Command Modes
MST configuration (config-mst)
Command History Release
12.2(14)SX
12.2(17d)SXB
12.2(33)SRA
15.0(1)MR
Usage Guidelines
If you do not map VLANs to the same instance as the associated primary VLAN when you exit the Multiple
Spanning Tree (802.1s) (MST) configuration submode, a warning message displays and lists the
secondary VLANs that are not mapped to the same instance as the associated primary VLAN. The
private-vlan synchronize command automatically maps all secondary VLANs to the same instance as
the associated primary VLANs.
Examples
This example assumes that a primary VLAN 2 and a secondary VLAN 3 are associated to VLAN 2, and that
all VLANs are mapped to the Common and Internal Spanning Tree (CIST) instance 1. This example also
shows the output if you try to change the mapping for the primary VLAN 2 only:
Router(config)# spanning-tree mst configuration
Router(config-mst)# instance 1 vlan 2
Router(config-mst)# exit
These secondary vlans are not mapped to the same instance as their primary:
-> 3
This example shows how to initialize private VLAN (PVLAN) synchronization:
Router(config-mst)# private-vlan synchronize
Router(config-mst)#
