underlying-interface (demux0)
Syntax
Hierarchy Level
Release Information
Statement introduced in Junos OS Release 9.3.
Support for aggregated Ethernet introduced in Junos OS Release 9.4.
Description
Configure the underlying interface on which the demultiplexing (demux) interface is running.
Options
underlying-interface-name—Either the specific name of the interface on which the DHCP discover packet arrives or one of the following interface variables:
- $junos-underlying-interface when configuring dynamic IP demux interfaces.
- $junos-interface-ifd-name when configuring dynamic VLAN demux interfaces.
The variable is used to specify the underlying interface when a new demux interface is dynamically created. The variable is dynamically replaced with the underlying interface that DHCP supplies when the subscriber logs in.
 | Note: Logical demux interfaces are currently supported on Gigabit Ethernet, Fast Ethernet, 10-Gigabit Ethernet, or aggregated Ethernet interfaces. |
Required Privilege Level
interface—To view this statement in the configuration.
interface-control—To add this statement to the configuration.
