    Hello,

    Configuring Q-in-Q Tunneling and VLAN Q-in-Q Tunneling and VLAN Translation

    Model: qfx5220-32cd
    Junos: 22.3R3-S2.2-EVO
    Yocto: 3.0.2
    Linux Kernel: 5.2.60-yocto-standard-g278f9ad
    JUNOS-EVO OS 64-bit [junos-evo-install-qfx-ms-x86-64-22.3R3-S2.2-EVO]

    to Uplink

    show interfaces ae0
    flexible-vlan-tagging;
    mtu 9216;
    encapsulation flexible-ethernet-services;
    aggregated-ether-options {
        minimum-links 1;
        link-speed 100g;
        lacp {
            active;
            periodic fast;
        }
    }
    unit 2 {
        encapsulation vlan-bridge;
        vlan-id 2;
        family inet {
            address 10.2.2.154/24;
        }
    }
    unit 3050 {
        encapsulation vlan-bridge;
        vlan-id 3050;
    }

    To Customer

     show interfaces et-0/0/4
    flexible-vlan-tagging;
    encapsulation flexible-ethernet-services;
    unit 3050 {
        encapsulation vlan-bridge;
        vlan-id-list 1-4094;
        input-vlan-map {
            push;
            vlan-id 3050;
        }
        output-vlan-map pop;
    }

    show vlans Cust-qinq_3050
    interface et-0/0/4.3050;
    interface ae0.3050;

    What's wrong? I cannot pack the client's cvlan into svlan 3050. There are no mac addresses on both sides. if I do set vlans Cust-qinq_3050 vlan-id 3050 I see the MAC from the Uplink port but then I get the error

     'et-0/0/4.3050'
        interface with vlan-id-list/inner-list cannot be added to a vlan with a vlan-id/vlan-tags configured
    error: configuration check-out failed: (statements constraint check failed)

    flexible-vlan-tagging;

    How can I configure QinQ to encapsulate customer VLANs (C-VLANs) into a service VLAN (S-VLAN) on a  device?

    That's crazy but flexible-vlan-tagging is not supported on QFX5220 o_O

    [QFX5220]flexible-vlan-tagging config is not supported

    And indeed, Q-in-Q is not supported on QFX5220: Q-in-Q (Features Explorer)
