Network Interfaces

All Juniper Networks devices use network interfaces to make physical connections to other devices. A connection takes place along media-specific physical wires through an I/O Card (IOC) in the SRX Series Services Gateway or a port on a Physical Interface Module (PIM) installed in the J Series Services Router. Networking interfaces primarily provide traffic connectivity.

You must configure each network interface before it can operate on the device. Configuring an interface can define both the physical properties of the link and the logical properties of a logical interface on the link.

Table 3 describes network interfaces that are available on SRX Series and J Series devices.
