    Release Information

    Statement introduced in Junos OS Release 11.1 for the QFX Series.


    Configure protocol family information for the logical interface on the QFX Series product.


    Access interfaces on the QFX Series are set to family ethernet-switching by default. If you are going to change the family setting for an interface, you might have to delete this default setting or any user-configured family setting first.

    You must configure a logical interface to be able to use the physical device.


    See Table 1 for protocol families available on the QFX Series interfaces. Different protocol families support different subsets of the interface types on the QFX Series.

    Interface types on the switch are:

    • Aggregated Ethernet (ae)
    • Gigabit Ethernet (ge)
    • Loopback (lo0)
    • Management Ethernet (me0)
    • Routed VLAN interface (RVI) (vlan)
    • 10-Gigabit Ethernet (xe)

    Not all interface types support all family substatements. Check your switch CLI for supported substatements for a particular protocol family configuration.
