MX304 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-fpc/pic/port

  • type—Media type, which identifies the network device. For example:

    • xe—10GbE interface

    • et—100GbE interfaces (40GbE, 100GbE, 400GbE )

  • fpc—The CLI displays FPC 0 for all the LMICs.

  • (Junos OS 24.4R1 and later) mic/pic—Logical PIC on the LMIC.

    (Junos OS releases earlier than 24.4R1) pic—Logical PIC on the LMIC.

  • port—Port number.

MX304 LMIC LEDs

Description

OK/FAIL

Green

On steadily

LMIC is functioning normally, and the link is up.
