MX960 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 MX960 router, the DPCs are represented in the CLI as
FPC 0throughFPC 11.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 DPCs Supported on MX240, MX480, and MX960 Routers in the MX Series Interface Module Reference.
port—Port number.
The MX960 router supports up to twelve DPCs that install vertically and are numbered 0 through 11 from left to right.
Figure 1 shows a 40-port Gigabit Ethernet DPC with SFP installed in slot 3 on the MX960 router.
The DPC contains four logical PICs, numbered PIC 0 through PIC 3 in the CLI. Each logical PIC contains 10
ports numbered 0 through 9.
The show chassis hardware command output displays
a 40-port Gigabit Ethernet DPC with SFP (DPCE-R-40GE-SFP) installed in DPC slot 3. The DPC is shown as FPC 3 and the DPC’s four logical PICs — 10x 1GE(LAN) — are shown as PIC 0 through PIC 3.
