Stacking a VLAN Tag
To stack a VLAN tag on all tagged frames entering or exiting the interface, include the push, vlan-id, and tag-protocol-id statements in the input VLAN map or the output VLAN map:
You can include these statements at the following hierarchy levels:
- [edit interfaces interface-name unit logical-unit-number]
- [edit interfaces interface-name unit logical-unit-number]
- [edit logical-systems logical-system-name interfaces interface-name unit logical-unit-number]
- [edit logical-systems logical-system-name interfaces interface-name unit logical-unit-number]
The VLAN IDs you define in the input VLAN maps are stacked on top of the VLAN ID bound to the logical interface.
All TPIDs you include in input and output VLAN maps must be among those you specify at the [edit interfaces interface-name ether-options ethernet-switch-profile tag-protocol-id [ tpids ]] hierarchy level.
