NOTE
The show optic function takes advantage of information stored and supplied by the manufacturer of the
XFP, SFP, or SFP+ 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 XFP, SFP, or SFP+ 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.
Output from the show optic command
TABLE 29
Field
Description
Port
The Brocade port number.
Temperature
• The operating temperature, in degrees Celsius, of the optical transceiver.
• The alarm status, as described in the next table.
Tx Power
• 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.
Rx Power
• 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.
Tx Bias Current • The transmit bias power signal, in milliamperes (mA).
• The alarm status, as described in the next table.
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.
Alarm status value description
TABLE 30
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.
