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
Table 2 describes the link LEDs on the MX304 LMIC (multi-rate) front panel.
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. |
Starting with Junos OS 24.4R1 and later, along with checking the LMIC’s LED status
indicators, use the show chassis fpc mic-status
command to verify
the LMIC online or offline status before the LMIC insertion or removal process.
MX304 LMIC Port LEDs
Table 3 describes the link LEDs for the LMIC ports on the MX304 front panel.

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. |
