OS for EX Series Ethernet Switches, Release 10.4
show interfaces diagnostics optics interface-name
Command introduced in Junos OS Release 10.0 for EX Series switches.
Display diagnostics data and alarms for Gigabit Ethernet optical transceivers (SFP, SFP+,
or XFP) installed in EX Series switches. The information provided by this command is
known as digital optical monitoring (DOM) information.
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
transceiver is not working.

Field Description
Displays the name of the physical interface.
Displays the magnitude of the laser bias power setting current, in
milliamperes. The laser bias provides direct modulation of laser diodes
and modulates currents.
Displays the laser output power, in milliwatts (mW) and decibels referred
to 1.0 mW (dBm).
Displays the temperature, in Celsius and Fahrenheit.
