COMMAND USAGE
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.
