Hi, actually Juniper published PR1568533 about this (as it should have worked like KB35261 says but it was not) – the PR says it's fixed in 19.4R3-S3 too, by the way. Olivier > Le 19 mai 2021 à 13:26, Antti Ristimäki a écrit : > > Hi list, > > Just as a follow-up and for possible future

Hi list, Just as a follow-up and for possible future reference, 18.4R3-S7 indeed sends the untagged customer frames with only SVLAN tag to QinQ uplink, but 18.4R3-S8 again reverts the behaviour such that those frames are sent double-tagged with both SVLAN and native-vlan. Tested with

Hi Karsten, Thanks for the link, I wasn't aware of such KB article, although there are several other articles related to native-vlan handling. The QFX5110 in question was previously running 17.3R3-S3 and there the native-vlan was indeed double-tagged on the uplink, just like the table says.

Hi list, Returning to this old thread. It seems that the behaviour has again changed, because after upgrading QFX5110 to 18.4R3-S7 the switch does not add the native-vlan tag when forwarding the frame to QinQ uplink. Previously with version 17.3 the switch did add the native-vlan tag along

Hi! Looks like JunOS 18.something introduced an incompatibility of native vlan handling in QinQ scenario between ELS (qfx, ex2300) and non-ELS switches: when ELS switch forwards untagged frame to QinQ, it now adds two vlan tags (one specified as native for interface and S-vlan) instead of
