Tx Bias Current • The transmit bias power signal, in milliamperes (mA).
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. The following table 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 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.

Description
• The operating temperature, in degrees Celsius, of the optical transceiver.
• The alarm status, as described in the next table.
• The transmit power signal, in decibels (dB), of the measured power referenced to one milliwatt
(mW).
• The alarm status, as described in the next table.
• The receive power signal, in decibels (dB), of the measured power referenced to one milliwatt
(mW).
• The alarm status, as described in the next table.
• The alarm status, as described in the next table.
Alarm status value description
Monitored level has dropped below the "low-alarm" threshold set by the manufacturer of the optical
transceiver.
Monitored level has dropped below the "low-warn" threshold set by the manufacturer of the optical
transceiver.
Monitored level is within the "normal" range set by the manufacturer of the optical transceiver.
Monitored level has climbed above the "high-warn" threshold set by the manufacturer of the optical
transceiver.
Monitored level has climbed above the "high-alarm" threshold set by the manufacturer of the
optical transceiver.
