Description
Configure the interfaces on the QFX Series and EX Series.
Most standard Junos OS configuration statements are available in the Junos OS for a switch. This topic lists Junos OS statements that you commonly use when configuring a switch as well as statements added to support switches only.
View the Feature Explorer to know the support platforms for the powersaving feature.
Options
aex—Configure an aggregated Ethernet interface.
xe-0/0/port/—Configure a 10-Gigabit Ethernet interface.
ge-0/0/port/—Configure a Gigabit Ethernet interface.
fc-0/0/port/—Configure a Fibre Channel interface.
meX/—Configure a management interface.
mc-ae—Configure a multichassis aggregated Ethernet (MC-AE) interface.
The remaining statements are explained separately. See CLI Explorer.
Required Privilege Level
interface—To view this statement in the configuration.
interface-control—To add this statement to the configuration.
Release Information
Statement introduced in Junos OS Release 11.1.
Statement support for QFX series introduced in Junos OS EVO Release 21.3
