Hi! Experts

End user asked us to implement QinQ (translate inner tag and push outer
tag) in QFX5100, but from POC it did not work as expected,  Could QFX work
as in the configuration below?  Someone said  QFX could only handle outer
tag. Thanks for your advice. *Requirement:*
QFX et-0/0/0/48 receive customer traffic with vlan 96, QFX5100 need push
SVLAN tag 10 when sending out from interface et-0/0/49;
QFX et-0/0/0/48 receive customer traffic with vlan 914, QFX5100 need
translate CVLAN from 914 to 200 and push SVLAN tag 10 when sending out from
interface et-0/0/49; *POC configuration:* lab at GM2# show interfaces
et-0/0/48 flexible-vlan-tagging; mtu 9000; encapsulation
flexible-ethernet-services; unit 10 { encapsulation vlan-bridge; vlan-id
96; input-vlan-map { swap-push; vlan-id 10; inner-vlan-id 96; }
output-vlan-map pop-swap; } unit 20 { encapsulation vlan-bridge; vlan-id
914; input-vlan-map { swap-push; vlan-id 10; inner-vlan-id 200; }
