Digital optical monitoring 9
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. Table 4 9 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.
TABLE 48 Output from the show optic command
Field Description
Port The Brocade port number.
Temper ature •The operating temperature, in degrees Celsius, of the optical
transceiver.
•The alarm status, as described in Table 49.
Tx Power •The transmit power signal, in decibels (dB), of the measured power
referenced to one milliwatt (mW).
•The alarm status, as described in Table 49.
Rx Power •The receive power signal, in decibels (dB), of the measured power
referenced to one milliwatt (mW).
•The alarm status, as described in Table 49
Tx Bias Current •The transmit bias power signal, in milliamperes (mA).
•The alarm status, as described in Table 49.
TABLE 49 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.
