disable (Interface)

Syntax disable;

Hierarchy Level [edit interfaces interface-name],

[edit interfaces interface-name unit logical-unit-number],

[edit logical-systems logical-system-name interfaces interface-name unit logical-unit-number]

Release Information Statement introduced before Junos OS Release 7.4.

Statement introduced in Junos OS Release 9.0 for EX Series switches.

Statement introduced in Junos OS Release 12.2 for ACX Series Universal Access Routers.

Description Disable a physical or a logical interface, effectively unconfiguring it.

CAUTION:

Dynamic subscribers and logical interfaces use physical interfaces for

connection to the network. The Junos OS allows you to set the interface

•

to disable and commit the change while dynamic subscribers and logical

interfaces are still active. This action results in the loss of all subscriber

connections on the interface. Use care when disabling interfaces.

• If aggregated SONET links are configured between a T1600 router and a

T4000 router, interface traffic is disrupted when you disable the physical

interface configured on the T1600 router. If you want to remove the

interface, we recommend that you deactivate the interface instead of

disabling it.

NOTE:

When you use the disable statement at the [edit interfaces] hierarchy level,

depending on the PIC type, the interface might or might not turn off the

•

laser. Older PIC transceivers do not support turning off the laser, but newer

Gigabit Ethernet (GE) PICs with SFP and XFP transceivers and ATM MIC

with SFP do support it and the laser will be turned off when the interface

is disabled. If the ATM MIC with SFP is part of an APS group, then the laser

will not be turned off when you use the disable statement at the [edit

interfaces] hierarchy level..

• When you disable or deactivate an interface, then all the references made

to the deactivated interface must be removed from the routing instance.

WARNING: Do not stare into the laser beam or view it directly with optical

instruments even if the interface has been disabled.
