Configure a dynamic logical interface on the physical device. You must configure a logical interface to be able to use the physical device.


logical-unit-number—Either the specific unit number of the interface or the unit number variable ($junos-interface-unit). The variable is used to specify the unit of the interface when a new demux interface is dynamically created. The static unit number variable is dynamically replaced with the unit number that DHCP supplies when the subscriber logs in.
