Router Interfaces Overview
Routers typically contain several different types of interfaces suited to various functions. For the interfaces on a router to function, you must configure them, specifying properties such as the interface location (that is, the slot in which the Flexible PIC Concentrator [FPC] or Dense Port Concentrator [DPC] is installed, and the location where the Physical Interface Card [PIC] is installed), the interface type (such as SONET/SDH, Asynchronous Transfer Mode [ATM], or Ethernet), encapsulation, and interface-specific properties. You can configure the interfaces that are currently present in the router, and you can also configure interfaces that are not currently present but that you might add in the future. When a configured interface appears, the Junos OS detects its presence and applies the appropriate configuration to it.
To determine which interfaces are currently installed in the router, issue the show interfaces terse operational mode command. If an interface is listed in the output, it is installed in the router. If an interface is not listed in the output, it is not installed in the router.
For information about which PICs are supported on your router, see your router’s PIC guide.
You can configure Junos class-of-service (CoS) properties to provide a variety of classes of service for different applications, including multiple forwarding classes for managing packet transmission, congestion management, and CoS-based forwarding. For more information about configuring CoS properties, see the Junos OS Class of Service Library for Routing Devices.
