MX2010 Port and Interface Numbering
In the physical part of the interface name, a hyphen (-) separates the media type from the MPC number (represented as an FPC in the CLI), and a slash (/) separates the logical PIC and port numbers:
type—Media type, which identifies the network device. For example:
ge—Gigabit Ethernet 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 MX2010 router, the MPCs are represented in the CLI as FPC 0 through FPC 9.
pic—Logical PIC on the MIC. The number of logical PICs varies depending on the type of MIC.
The MIC number is not included in the interface name.
The MX2010 supports up to ten MPCs that install vertically and are numbered from left to right.
The following sample CLI output displays an MPC (
Type 2 3D) installed in MPC slot

There is one 10-Gigabit Ethernet MIC (
MIC-3D-2XGE-XFP) installed into the MPC,
MIC 0 (top slot),
and one 10-Gigabit Ethernet MIC (
MIC-3D-4XGE-XFP) installed into the MPC,
MIC 1 (bottom slot).
Each MIC is logically divided into two PICs in the CLI.
The port numbers on the MICs correspond to the port number in the interface. See the MX Series Interface Module Reference for more information about specific MICs.
Figure 1 shows how the interfaces correspond to the ports on the MIC.
The slot number will be different depending on which slot the MPC and MIC is installed.
The show interfaces terse command displays the two
10-Gigabit Ethernet interfaces, xe-9/0/0 and xe-9/1/0 that correspond to the two ports on the MIC card that is installed
0 of the MPC, and four 10-Gigabit Ethernet
interfaces, xe-9/2/0, xe-9/2/1, xe-9/3/0, and xe-9/3/1 that correspond to the four ports on the
MIC card that is installed in slot
1 of the MPC.
