Display Digital Diagnostics Monitoring information for optical PTMs

Use this procedure to display Digital Diagnostics Monitoring (DDM) information for optical PTMs.

Obtain the work instructions for this procedure.

From the Navigation menu, select Port → Ethernet Port → Digital Diagnostics Monitoring.

Result:

The Digital Diagnostics Monitoring screen displays.

In the Interface drop-down box, select All or an individual port being monitored.

Result:

The Digital Diagnostics Monitoring screen displays the following information:

Parameter	Description	CLI command
Interface	The Slot/Port that supports optical SFPs.	`show ddm`
Name	Pluggable transmission module name representing the rate(s) supported by the PTM. It is a character string containing one or more rates separated by "//". See `show ddm` command in Switching Commands CLI document for details.
Qualifier	Pluggable transmission module qualifier. It is a character string containing one or more qualifiers separated by "//". See `show ddm` command in Switching Commands CLI document for details.
Rx Power	PTM optical receive power in dBm. Valid values: -40.0 to +8.2 or "LOS".
Tx Power	PTM optical transmit power in dBM. Valid values: -40.0 to +8.2 or "NA" meaning the laser is turned off.
Laser Bias Current	PTM laser bias current in milliamperes. Valid values: 0.0 to 131.0.
Power Supply Voltage	PTM measured power supply voltage in volts. Valid values: 0 to +6.55.
Temperature	PTM transceiver temperature in degrees Celcius. Valid values: -128.0 to +128.0.
Calibration	Calibration mode Valid values: external or internal
