Command Usage
â—† The switch can display diagnostic information for SFP modules which support
the SFF-8472 Specification for Diagnostic Monitoring Interface for Optical
Transceivers. This information allows administrators to remotely diagnose
problems with optical devices. This feature, referred to as Digital Diagnostic
Monitoring (DDM) in the command display, provides information on
transceiver parameters including temperature, supply voltage, laser bias
current, laser power, received optical power, and related alarm thresholds.
â—† The DDM thresholds displayed by this command only apply to ports which
have a DDM-compliant transceiver inserted.
