[j-nsp] QFX 5100 and vlan rewriting

Hey!

I am a bit puzzled how to do VLAN rewriting with the QFX5100. With a MX,
the following configuration would work:

interfaces {
 xe-0/0/0 {
  unit 0 {
   family bridge {
    interface-mode trunk;
    vlan-id-list [ 57 58 ];
    vlan-rewrite {
      translate 3 57;
      translate 4 58;
    }
   }
  }
 }
}

With a QFX5100, running 17.4, there is no "vlan-id-list" under "family
ethernet-switching" (but there is "inner-vlan-id-list" and there is
"vlan-id-list" outside "family ethernet-switching"). If I don't specify
anything, I get an error message saying to use "vlan members". However,
the following configuration does not translate VLANs:

interfaces {
 xe-0/0/0 {
  unit 0 {
   family ethernet-switching {
    interface-mode trunk;
    vlan members [ vlan-57 vlan-58 ];
    vlan-rewrite {
      translate 3 57;
      translate 4 58;
    }
   }
  }
 }
}
vlans {
 vlan-57 vlan-id 57;
 vlan-58 vlan-id 58;
}

Am I doing something wrong? Thanks!
