Configuring Stacked VLAN Tagging
To configure stacked VLAN tagging for all logical interfaces on a physical interface, include the stacked-vlan-tagging statement at the [edit interfaces interface-name] hierarchy level:
[edit interfaces interface-name]stacked-vlan-tagging;
If you include the stacked-vlan-tagging statement in the configuration, you must configure dual VLAN tags for all logical interfaces on the physical interface. For more information, see Stacking a VLAN Tag.
