Configuring QnQ on a EX5100 on an already exisiting Trunk port.

  • 1.  Configuring QnQ on a EX5100 on an already exisiting Trunk port.

    Posted 11-29-2022 11:28

    I need to add QnQ VLAN to an existing trunk port on a QFX5100.  I have a EX4200 -> MX480 - > QFX5100 

    Here are the existing Interface configuration on the QFX5100 

    set interfaces ae4 aggregated-ether-options no-flow-control
    set interfaces ae4 aggregated-ether-options link-speed 10g
    set interfaces ae4 aggregated-ether-options lacp active
    set interfaces ae4 aggregated-ether-options lacp periodic fast
    set interfaces ae4 unit 0 family ethernet-switching port-mode trunk
    set interfaces ae4 unit 0 family ethernet-switching vlan members 700
    set interfaces ae4 unit 0 family ethernet-switching vlan members 710

    when I try to add a QnQ configuration to the port based on the juniper doc:  I see a few issue 

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

    1.) set vlans service-vlan dot1q-tunneling command doesn't exist 

    2.) When I try to set a push and pop mapping 

    set interfaces ae4 unit 2000 vlan-id 2000
    set interfaces ae4 unit 2000 input-vlan-map push
    set interfaces ae4 unit 2000 output-vlan-map pop
    set interfaces ae4 unit 2000 vlan-id-list [100-200] 

    I get the following error "interface with vlan-id-list/inner-list cannot be added to a vlan with a vlan-id/vlan-tags configured" 

    How can I configure this existing interface to accept QnQ tags
