MX480 MIC Port and Interface Numbering

Each port on a MIC corresponds to a unique interface name in the CLI.
NOTE: Fixed configuration MPCs, that is, MPCs with built-in MICs follow the port numbering
of DPCs.
In the syntax of an interface name, a hyphen (-) separates the media type from the MPC number (represented
as an FPC in the CLI). The MPC 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 MIC. Slashes (/) separate the MPC 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 MPC is installed. On the MX480 router, the MPCs are represented in the CLI as
FPC 0 through FPC 5.
pic—Logical PIC on the MIC, numbered 0 or 1 when installed in slot 0, and 2 or 3 when installed in slot
1. The number of logical PICs varies depending on the type of MIC. For example, a:
20-port Gigabit Ethernet MIC has two logical PICs, numbered 0 and 1 when installed in slot 0, or 2
and 3 when installed in slot 1.
4-port 10-Gigabit Ethernet MIC has two logical PICs numbered 0 and 1 when installed in slot 0, or 2
and 3 when installed in slot 1.
100-Gigabit Ethernet MIC with CFP has one logical PIC numbered 0 when installed in slot 0, or 2 when
installed in slot 1.
