Use the show optic slot slot-number on a FastIron X Series chassis to view information about all
qualified XFPs, SFPs, and SFP+ in a particular slot. The following shows example output.

Syntax: show optic slot slot-number
NOTE
The show optic slot slot-number command is supported on the FSX 800 and FSX 1600 only.
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.
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 21 describes each of these status values.

referenced to one milliwatt (mW).
• The alarm status, as described in Table 21.
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 21
Tx Bias Current
• The transmit bias power signal, in milliamperes (mA).
• The alarm status, as described in Table 21.
