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.
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
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 do support it
and the laser will be turned off when the interface is disabled.
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.
