show optic
User EXEC mode
This command takes advantage of information stored and supplied by the manufacturer of the QSFP+, 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. When the QSFP+, SFP, or SFP+ transceiver does not supply the information, a "Not Available" message is displayed for the specific port on which the module is installed.
The
show optic command displays the following information:
| Output field | Description |
|---|---|
| Temperature | The operating temperature, in degrees Celsius, of the optical transceiver, followed by the alarm status. |
| Tx Power | The transmit power signal, in decibels (dB), of the measured power referenced to one milliwatt (mW), followed by the alarm status. |
| Rx Power | The receive power signal, in decibels (dB), of the measured power referenced to one milliwatt (mW), followed by the alarm status. |
| Tx Bias Current | The transmit bias power signal, in milliamperes (mA), followed by the alarm status. |
| Voltage | The current voltage. |
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 alarm status values.
Alarm Status Values
| Status value | Description |
|---|---|
| Low-Alarm | The monitored level has dropped below the "low-alarm" threshold set by the manufacturer of the optical transceiver. |
| Low-Warn | The monitored level has dropped below the "low-warn" threshold set by the manufacturer of the optical transceiver. |
| Normal | The monitored level is within the "normal" range set by the manufacturer of the optical transceiver. |
| High-Warn | The monitored level has climbed above the "high-warn" threshold set by the manufacturer of the optical transceiver. |
| High-Alarm | The monitored level has climbed above the "high-alarm" threshold set by the manufacturer of the optical transceiver. |
