MX Series Router Interface Identifiers

The MX Series routers use the convention ge-fpc/pic/port to identify interfaces.

fpc identifies the number of the FPC or DPC card on which the physical interface is located. Specifically, it is the number of the slot in which the card is installed. If two Switch Control Boards (SCBs) are installed in an MX960 router, the FPC range is from 0 through 11. If three SCBs are installed, the range is from 0 through 5 and from 7 through 11. On the MX480 router, the range is from 0 through 6. On the MX240 router, the range is from 0 through 2 with one SCB installed. With two SCBs installed, the DPC can be installed in any of two consecutive interface card slots, the range is from 1 through 2.

For DPCs, the PIC and port numbers are identified on the DPC front panel. Use the PIC and port numbers that correspond to the port you are configuring.

Ports are numbered from 0 through 9 for Gigabit Ethernet and Tri-Rate Ethernet copper interfaces. Port numbers are always 0 for 10-Gigabit Ethernet interfaces.

Note: In certain displays, the MX Series routers identify the Packet Forwarding Engine (PFE) rather than the PIC number. PFE 0 corresponds to PIC 0, PFE 1 corresponds to PIC 2, PFE 2 corresponds to PIC 1, and PFE 3 corresponds to PIC 3.
