MX480 DPC Port and Interface Numbering

Each port on a DPC corresponds to a unique interface name in the CLI.
In the syntax of an interface name, a hyphen (-) separates the media type from the DPC number (represented
as an FPC in the CLI). The DPC slot number corresponds to the first 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-fpc/pic/port
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 FPC 5.
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.
For more information on specific DPCs, see
on page 116 in the MX Series Interface Module
port—Port number.
The MX480 router supports up to six DPCs that install horizontally and are numbered 0 through 5 from
bottom to top.
Figure 31 on page 113 shows a 40-port Gigabit Ethernet DPC with SFP installed in slot 3 on the MX480
router.
