show interfaces diagnostics optics (SONET)

Syntax

show interfaces diagnostics optics so-fpc/pic/port

Release Information

Command introduced in JUNOS Release 7.5.

Description

(T640 routers only) Display diagnostics data and alarms for OC768 SONET interfaces. The 300-pin Multisource Agreement (MSA) toolkit polls the PIC at 1-second intervals. The alarms do not generate SNMP traps, administratively disable interfaces, or cause the LEDs to change color.

Output Fields

Table 52 lists the output fields for the show interfaces diagnostics optics command. Output fields are listed in the approximate order in which they appear.



Table 52: show interfaces diagnostics optics Output Fields 

Field Name	Field Description
Physical interface	Name of the physical interface.
Laser bias current	Magnitude of the laser bias power setting current, in milliamperes. This indicator is a software equivalent to the LsBIASMON pin in hardware.
Laser output power	Laser output power, in milliwatts (mW) and decibels, referenced to 1.0 mW (dBm). This is a software equivalent to the LsPOWMON pin in hardware.
Receiver signal average optical power	Average received optical power, in mW and dBm. This indicator is a software equivalent to the RxPOWMON pin in hardware. Average optical power is vendor-specific. For example: Intel—Rx power monitor: +/- 1dB Opnext—Rx power monitor: +/- 1.5 dB
Laser end-of-life alarm	Laser end-of-life alarm: On or Off.
Laser wavelength alarm	Laser wavelength alarm: On or Off.
Laser bias current alarm	Laser bias current alarm: On or Off.
Laser temperature alarm	Laser temperature alarm: On or Off.
Laser power alarm	Laser power alarm: On or Off.
Modulator temperature alarm	(Opnext 300-pin MSA transponders only) Modulator temperature alarm: On or Off.
Modulator bias alarm	Modulator bias alarm: On or Off.
Tx multiplexer FIFO error alarm	Transmit multiplexer first in, first out (FIFO) error alarm: On or Off.
Tx loss of PLL lock alarm	Transmit loss of phase-locked loop (PLL) lock alarm: On or Off.
Rx loss of average optical power alarm	Receive loss of average optical power alarm: On or Off.
Rx loss of AC power alarm	(Opnext 300-pin MSA transponders only) Receive loss of AC power alarm: On or Off.
Rx loss of PLL lock alarm	Receive loss of phase-locked loop (PLL) lock alarm: On or Off.
