Don’t Be Intimidated by Junos’ Interface Naming Conventions

It’d be a lie to say that Junos’ naming conventions for their interfaces are simple. The naming conventions can be broken down and explained, but mastering them takes an investment. To name the interfaces properly, you’ll need to understand the device in question, the series it comes from and how the conventions are broken down.

In the Junos OS, the following convention is used to specify the physical part of an interface: device name:type-fpc/pic/port. The punctuation matters, but let’s focus on the four distinct sections: (1) device-name, (2) type-fpc, (3) pic, and (4) port.

“device-name” is 128 characters and is either the serial number or alias of the component. “type” is two or three letters that denote the type of interface, such as “fc” for Fibre Channel or “xle” for 40-gigabit service interface. “fpc” is the Flexible PIC Concentrator, the value of which changes based on the model you’re dealing with. “pic” represents the Physical Interface Card, and it also changes based on the device and software package you’re dealing with.
