    Release Information

    Statement introduced in Junos OS Release 9.0 for EX Series switches, including options ethernet-switching, inet, and iso.

    Option inet6 introduced in Junos OS Release 9.3 for EX Series switches.

    Options ccc and mpls introduced in Junos OS Release 9.5 for EX Series switches.


    Configure protocol family information for the logical interface on the switch.

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


    Interfaces on EX2200, EX3200, EX3300, EX4200, and EX4500 switches are set to family ethernet-switching by the default factory configuration. Before you can change the family setting for an interface to another family type, you must delete this default setting or any user-configured family setting. EX6200 and EX8200 switch interfaces do not have a default family setting.


    See Table 1 for protocol families available on the switch interfaces. Different protocol families support different subsets of the interface types on the switch. Interface types on the switch are:

    • Aggregated Ethernet (ae)

    • Gigabit Ethernet (ge)

    • Interface-range configuration (interface-range)

    • Loopback (lo0)

    • Management Ethernet (me0)

    • Routed VLAN interface (RVI) (vlan)

    • Virtual management Ethernet (vme)

    • 10-Gigabit Ethernet (xe)

    If you are using an interface range, the supported protocol families are the ones supported by the interface types that compose the range.

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