show interfaces diagnostics optics
Syntax
Release Information
Command introduced in Junos OS Release 10.1.
Description
Display diagnostics data and alarms for Gigabit Ethernet optical transceivers (SFP) installed in SRX Series Services Gateways. 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.
In a chassis cluster, the show interfaces diagnostics optics command works only on the node that is primary in redundancy group 0 (RG0).
