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 49

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.

Output from the show optic command

Field

Description

Port

The Brocade port number.

Temperature

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.
