Digital Diagnostics Monitoring
Page 34 7750 SR Interface Configuration Guide
DDM MIB variables to set custom event thresholds if the factory-programmed thresholds are not
at the desired levels.
The following are potential uses of the DDM data:
• Optics degradation monitoring — With the information returned by the DDM-capable
optics module, degradation in optical performance can be monitored and trigger events
based on custom or the factory-programmed warning and alarm thresholds.
• Link/router fault isolation — With the information returned by the DDM-capable optics
module, any optical problem affecting a port can be quickly identified or eliminated as the
potential problem source.
Supported real-time DDM features are summarized in Table 4.
