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.
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. For
a list of transceivers supported on EX Series switches and their specifications, including
DOM support, see Pluggable Transceivers Supported on EX Series Switches.
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-name—Name 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.
