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
For Temperature, Supply Voltage, TX Bias, TX Power, and RX Power, values are displayed for each of
the following four alarm and warning settings: High alarm, Low alarm, High warning, and Low
warning. The hexadecimal values are the manufacturer internal calibrations, as defined in the
SFF-8472 standard. The other values indicate at what level (above the high setting or below the
low setting) the system should send a warning message or an alarm. Note that these values are
set by the manufacturer of the optical transceiver, and cannot be configured.
Syslog messages for optical transceivers
The system generates Syslog messages for optical transceivers in the following circumstances:
TABLE 21 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.
