This article describes the case when you need to add a double tag on untagged traffic. Extreme XOS has this feature starting from software 16.2. This is supported on platforms:
– Summit X430, X440, X450-G2, X460, X460-G2, X480, X670, X670-G2, X770 series switches
– BlackDiamond X8 and 8000 series switches. (except BD8K: G48Te2, G24Xc, G48Xc, G48Tc, 10G4Xc, 10G8Xc, S-G8Xc, S-10G1Xc, S-10G2Xc, and 8500-series)
– E4G-200 and E4G-400 cell site routers
In the example below, the outer tag 10 and the inner tag 1000 will be added to all untagged traffic.
