Interface Process

The JUNOS interface process allows you to configure and control the physical interface devices and logical interfaces present in a router. You can configure various interface properties such as the interface location (that is, which slot the Flexible PIC Concentrator [FPC] is installed in and which location on the FPC the Physical Interface Card [PIC] is installed in), the interface encapsulation, and interface-specific properties. You can configure the interfaces that currently are present in the router, as well as interfaces that currently are not present but that you may be adding at a future time.

The JUNOS interface process communicates, through the JUNOS kernel, with the interface process in the Packet Forwarding Engine, thus enabling the JUNOS software to track the status and condition of the router's interfaces.
