Description
CAUTION:
Enabling tracing can adversely impact scale and performance and may increase security risk. We strongly recommend using the trace, tracing, or traceoptions commands only under the guidance of a JTAC support engineer. After collecting the debug information, immediately disable tracing to minimize risk and restore normal system performance.
Configure interfaces on the QFX Series and EX Series and ACX 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
