Syntax: show optic <port-number>
NOTE
The show optic function takes advantage of information stored and supplied by the manufacturer of
the XFP 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 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.
