Each port on a DPC corresponds to a unique interface name in the CLI.
In the syntax of an interface name, a hyphen (
number (represented as an
number in the interface. The second number in the interface corresponds to the logical
PIC number. The last number in the interface matches the port number on the DPC.
Slashes (
) separate the DPC number from the logical PIC number and port number.

type—Media type, which identifies the network device. For example:
ge—Gigabit Ethernet interface
so—SONET/SDH interface
xe—10-Gigabit Ethernet interface
For a complete list of media types, see Interface Naming Overview.
fpc—Slot in which the DPC is installed. On the MX480 router, the DPCs are represented
in the CLI as
FPC 0
through
pic—Logical PIC on the DPC. The number of logical PICs varies depending on the type
of DPC. For example, a:
20-port Gigabit Ethernet DPC has two logical PICs, numbered 0 through 1.
40-port Gigabit Ethernet DPC has four logical PICs, numbered 0 through 3.
2-port 10-Gigabit Ethernet DPC has two logical PICs, numbered 0 through 1.
4-port 10-Gigabit Ethernet DPC has four logical PICs, numbered 0 through 3.
