Overview of Digital Diagnostic MonitorThe Digital Diagnostic Monitor (DDM) allows you to perform diagnostic tests on transceiver modules suchas small form-factor pluggable (SFP). Run the show interface sfp ethernet port-number command to viewthe various parameters of the transceiver module, such as temperature, voltage, transmission power, and soon.

Monitor Digital Diagnostic MonitorUse the following command to monitor DDM test information.
