Appendix B Naming Conventions
M Series and J Series Interface Naming Conventions
The following provides the naming conventions used for all of the interfaces on the M Series and J Series routers.
M Series Interface Names
On the M Series Multiservice Edge Routers, when you display information about an interface, you specify the
interface type, the slot in which the FPC is installed, the slot on the FPC in which the PIC is located, and the
configured
port number.
In the physical part of the interface name, a hyphen (-) separates the media type from the FPC number, and a slash
(/) separates the FPC, PIC, and port numbers:
type-fpc/pic/port
Logical Part of an Interface Name (M Series Routers)
The logical unit part of the interface name corresponds to the logical unit number, which can be a number from 0
through 16384. In the virtual part of the name, a period (.) separates the port and logical unit numbers:
type-fpc/pic/port.logical
Example: “ge-0/1/0.0” indicates a Gigabit Ethernet connection - FPC 0, PIC 1, Physical Port 0.Logical Unit 0
J Series Interface Names
On the J Series Services Routers, when you display information about an interface, you specify the interface type, the
slot in which the Physical Interface Module (PIM) is installed, 0, and the configured port number.
In the physical part of the interface name, a hyphen (-) separates the media type from the PIM number, and a slash
(/) separates the PIM, 0, and port numbers:
type-pim/0/port
Example: “fe-0/1/0.0” indicates a Fast Ethernet connection - PIM 0 Slot 1/0/Physical Port 0.Logical Unit 0
SSG Series and ISG Series Interfaces
The SSG Series and ISG Series devices include integrated 10/100/1000 interfaces. It does not use a modifier to
indicate the distinction between 10/100 and Gigabit Ethernet connections. The SSG Series and ISG Series naming
convention is simplified as shown in the following:
Example: “ethernet0/0” indicates Ethernet interface 0/port 0
