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]

All TPIDs you include in input and output VLAN maps must be among those you specify at the [edit interfaces interface-name gigether-options ethernet-switch-profile tag-protocol-id [ tpids ]] hierarchy level. For more information, see Configuring Inner and Outer TPIDs and VLAN IDs.
