Removing the Outer VLAN Tag and Rewriting the Inner VLAN Tag
On Ethernet IQ, IQ2 and IQ2-E interfaces, on MX-series router Gigabit Ethernet, Tri-Rate Ethernet copper, and 10-Gigabit Ethernet interfaces, and on aggregated Ethernet interfaces using Gigabit Ethernet IQ2 and IQ2-E or 10-Gigabit Ethernet PICs on MX-series routing platforms, to remove the outer VLAN tag of the frame and replace the inner VLAN tag of the frame with a user-specified VLAN tag value, include the pop-swap statement in the input VLAN map or output VLAN map:
The inner tag becomes the outer tag in the final frame.
You can include this statements a 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 ]
