NOTE
The show optic function takes advantage of information stored and supplied by the manufacturer of
the SFP, SFP+, and QSFP+ transceiver. This information is an optional feature of the Multi-Source
Agreement standard defining the optical interface. Not all component suppliers have implemented
this feature set. In such cases where the SFP, SFP+, and QSFP+ transceiver does not supply the
information, a “Not Available” message will be displayed for the specific port on which the module
is installed.
The following table describes the information displayed by the show optic command.
For Temperature, Tx Power, Rx Power, and Tx Bias Current in the show optic command output,
values are displayed along with one of the following alarm status values: Low-Alarm, Low-Warn,
Normal, High-Warn or High-Alarm. The thresholds that determine these status values are set by the
manufacturer of the optical transceivers.
describes each of these status values.
Viewing optical transceiver thresholds
The thresholds that determine the alarm status values for an optical transceiver are set by the
manufacturer of the SFP, SFP+, and QSFP+. To view the thresholds for a qualified optical
transceiver in a particular port, use the show optic threshold command as shown below.

Alarm status value description
Status value
Description
Low-Alarm
Monitored level has dropped below the "low-alarm" threshold set by the manufacturer of the
optical transceiver.
Low-Warn
Monitored level has dropped below the "low-warn" threshold set by the manufacturer of the
optical transceiver.
Normal
Monitored level is within the "normal" range set by the manufacturer of the optical transceiver.
High-Warn
Monitored level has climbed above the "high-warn" threshold set by the manufacturer of the
optical transceiver.
High-Alarm
Monitored level has climbed above the "high-alarm" threshold set by the manufacturer of the
optical transceiver.
