Description
Configure the interface on which PPP over Ethernet is running.
For demux interfaces, configure the underlying interface on which the demultiplexing (demux) interface is running.
Options
interface-name—Name of the interface on which PPP over Ethernet or demux
is running. For example, at-0/0/1.0 (ATM VC), fe-1/0/1.0 (Fast Ethernet interface), ge-2/0/0.0 (Gigabit Ethernet
interface), ae1.0 (for IP demux on an aggregated Ethernet
interface), or ae1 (for VLAN demux on an aggregated Ethernet
interface).
Demux interfaces are currently supported on Gigabit Ethernet, Fast Ethernet, 10-Gigabit Ethernet interfaces, or aggregated Ethernet devices.
Required Privilege Level
interface—To view this statement in the configuration.
interface-control—To add this statement to the configuration.
Release Information
Statement introduced before Junos OS Release 7.4.
