Digital Diagnostics Monitoring
Some Alcatel-Lucent SFPs and XFPs have Digital Diagnostics Monitoring (DDM) capability
where the transceiver module maintains information about its working status in device registers
including:
•
Temperature
•
Supply voltage
•
Transmit (TX) bias current
•
TX output power
•
Received (RX) optical power
The transceiver is also programmed with warning and alarm thresholds for low and high
conditions that can generate system events. These thresholds are programmed by the transceiver
manufacturer.
There are no CLI commands required for DDM operations, however, the
show>port
port-id
detail
command displays DDM information in the Transceiver Digital Diagnostics Monitoring
output section.
DDM information is populated into the router’s MIBs, so the DDM data can be retrieved by
Network Management using SNMP. Also, RMON threshold monitoring can be configured for the
DDM MIB variables to set custom event thresholds if the factory-programmed thresholds are not
at the desired levels.
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.
