show interfaces diagnostics optics

 

Syntax

Release Information

Command introduced in Junos OS Release 10.0 for EX Series switches.

Command introduced in Junos OS Release 13.2X50-D15 for the QFX Series.

Command introduced in Junos OS Release 14.1X53-D20 for the OCX Series.

Description

Display diagnostics data and alarms for Gigabit Ethernet optical transceivers (SFP, SFP+, XFP, QSFP+, or CFP) installed in EX Series or QFX 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.

Options

interface-nameName of the interface associated with the port in which the transceiver is installed: ge-fpc/pic/port, xe-fpc/pic/port, or et-fpc/pic/port.
