Digital optical monitoring
Viewing optical transceiver thresholds
The thresholds that determine the alarm status values for an optical transceiver are set by the
manufacturer of the XFP, SFP, or SFP+. To view the thresholds for a qualified optical transceiver in
a particular port, use the show optic threshold command as shown below.
Syntax: show optic threshold <port>
Specify the port variable in one of the following formats:
• FWS, FCX, and ICX stackable switches – stack-unit/slotnum/portnum
• FSX 800 and FSX 1600 chassis devices – slotnum/portnum
• ICX devices – slotnum/portnum
• FESX compact switches – portnum
TABLE 91 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.
