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.
When the show optic command is
used without any further parameters, the optical monitoring status for all the
ports
present on the active unit and slave units is displayed.
DOM cannot be enabled for user disabled ports. When DOM is configured globally but a port is disabled by the user, the following appears in the output: "Optical monitoring is in progress, please try later".
The
show optic command displays the following information:
| Output field | Description |
|---|---|
| Port | The identifier for the physical port on the device where the optical transceiver is installed. |
| 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. |
