Release Information

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

Description

Specify the interfaces for which ingressing traffic is mirrored. Specify the interface that mirrored traffic should be copied to (the output interface).

Options

all—Apply port mirroring to all interfaces on the switch (except the output interface). Mirroring a high volume of traffic can cause performance issues, so you should generally select specific input interfaces.

Caution: Configuring all in a QFabric system causes all the access interfaces on all the nodes to be mirrored. Be cautious about using this option on a QFabric system.

interface-name—Apply port mirroring to the specified interface only.

Required Privilege Level

routing—To view this statement in the configuration.
routing-control—To add this statement to the configuration.
