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.
pic—Logical PIC on the LMIC.
port—Port number.

MX304 LMIC LEDs

Table 2 describes the link LEDs on the MX304 LMIC (multi-rate) front panel.

Table 2: MX304 LMIC LEDs
LED Status	Color	State	Description
OK/FAIL	Green	On steadily	LMIC is functioning normally, and the link is up.
	Red	-	LMIC has failed.
	Amber/Blinking		LMIC is transitioning.
	Off		LMIC is plugged-in but not powered on.
OFFLINE	Off	-	LMIC is offline.

MX304 LMIC Port LEDs

Table 3 describes the link LEDs for the LMIC ports on the MX304 front panel.

Table 3: LMIC Port LEDs
Color	State	Description
Green	On steadily	No breakout, port is up. Breakout, all lanes in that port are up.
Red	On steadily	Optics transceiver hardware failure.
Amber	On steadily	Any other fault except LOS and transceiver hardware failure.
Off		Pluggable not inserted. No breakout; Loss of signal detected. Breakout; Loss of signal on all lanes.
