show interfaces diagnostics optics

Syntax

show interfaces diagnostics optics interface-name

Release Information

Command introduced in JUNOS Release 9.0 for EX-series switches.

Description

Display diagnostics data and alarms for 10-Gigabit Ethernet dense wavelength-division multiplexing (DWDM) interfaces.

Thresholds that trigger a high alarm, low alarm, high warning, or low warning are set by the transponder vendors. Generally, a high alarm or low alarm indicates that the optics module is not operating properly. This information can be used to diagnose why a PIC is not working.

Options

interface-name — Interface name: ge-fpc/pic/port or xe-fpc/pic/port.

Required Privilege Level

Field Name

Field Description

Physical interface

Name of the physical interface.

Laser bias current

Magnitude of the laser bias power setting current, in milliamperes. The laser bias provides direct modulation of laser diodes and modulates currents.

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.

Module temperature

Temperature of the XFP optics module, in Celsius and Fahrenheit.

Laser rx power

Laser received optical power, in mW and dBm.

Laser bias current high alarm

Laser bias power setting high alarm. Displays on or off.

Laser bias current low alarm

Laser bias power setting low alarm. Displays on or off.

Laser bias current high warning

Laser bias power setting high warning. Displays on or off.

Laser bias current low warning

Laser bias power setting low warning. Displays on or off.

Laser output power high alarm

Laser output power high alarm. Displays on or off.

Module temperature high alarm

Module temperature high alarm. Displays on or off.

Module temperature low alarm

Module temperature low alarm. Displays on or off.

Module temperature high warning

Module temperature high warning. Displays on or off.

Laser rx power low alarm

Receive laser power low alarm. Displays on or off.

Laser rx power high warning

Receive laser power high warning. Displays on or off.

Laser rx power low warning

Receive laser power low warning. Displays on or off.

Module not ready alarm

Module not ready alarm. When on, indicates the module has an operational fault. Displays on or off.

Module power down alarm

Module power down alarm. When on, module is in a limited power mode, low for normal operation. Displays on or off.

Tx data not ready alarm

Any condition leading to invalid data on the transmit path. Displays on or off.

Tx not ready alarm

Any condition leading to invalid data on the transmit path. Displays on or off.

Tx laser fault alarm

Laser fault condition. Displays on or off.

Tx CDR loss of lock alarm

Transmit clock and data recovery (CDR) loss of lock. Loss of lock on the transmit side of the CDR. Displays on or off.

Rx not ready alarm

Any condition leading to invalid data on the receive path. Displays on or off.

Rx loss of signal alarm

Receive Loss of Signal alarm. When on, indicates insufficient optical input power to the module. Displays on or off.

Rx CDR loss of lock alarm

Receive CDR loss of lock. Loss of lock on the receive side of the CDR. Displays on or off.
