MST and Private VLAN Synchronize

A small example about the “private-vlan synchronize” command in MST configuration mode (vlan 100 = primary VLAN, vlan 101 = secondary (isolated) VLAN):

n5k-1(config-mst)# show
Pending MST Configuration
Name      [test]
Revision  0     Instances configured 3
Instance  Vlans mapped
--------  ---------------------------------------------------------------------
0         1000-4094
1         1-100
2         101-999
------------------------------------------------------------------------------- 

These secondary vlans are not mapped to the same instance as their primary:
-> 101
n5k-1(config-mst)# private-vlan synchronize
n5k-1(config-mst)# show
Pending MST Configuration
Name      [test]
Revision  0     Instances configured 3
Instance  Vlans mapped
--------  ---------------------------------------------------------------------
0         1000-4094
1         1-101
2         102-999
-------------------------------------------------------------------------------

As you see, it modified the MST instance configuration so that the secondary VLAN (101) was moved to the same MST instance as the primary VLAN.
