MX960 PIC Port and Interface Numbering

 

Each port on a PIC corresponds to a unique interface name in the CLI.

In the syntax of an interface name, a hyphen (-) separates the media type from the FPC slot number (represented as an FPC in the CLI). The FPC slot number corresponds to the first number in the interface. The second number in the interface corresponds to the PIC number. The last number in the interface matches the port number on the PIC. Slashes (/) separate the FPC number from the 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—Lowest slot number in which the FPC is installed. On the MX960 router, the FPCs occupy two slots and are represented in the CLI as FPC 0 through FPC 10.

  • pic—PIC number, 0 or 1 depending on the FPC slot.

    For more information on specific PICs, see PICs Supported by MX240, MX480, and MX960 Routers in the MX Series Interface Module Reference.

  • port—Port number.

The MX960 supports up to six FPCs that install vertically and are numbered from left to right. Each FPC accepts up to two PICs.
