The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product.

The Digital Diagnostic Monitor (DDM) allows you to perform diagnostic tests on transceiver modules such as small form-factor pluggable (SFP). Run the show interface sfp ethernet port-number command to view the various parameters of the transceiver module, such as temperature, voltage, transmission power, and so on.
Use the following command to monitor DDM test information.
