Hierarchy Level


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


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.


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.
