Digital Diagnostics Monitoring

Alcatel-Lucent SFPs and XFPs

The availability of the DDM real-time information and warning/alarm status is based on the
transceiver. It may or may not indicate that DDM is supported. Although some Alcatel-Lucent
SFPs support DDM, Alcatel-Lucent has not required DDM support in releases prior to Release
6.0. Non-DDM and DDM-supported SFPs are distinguished by a specific ICS value.
For Alcatel-Lucent SFPs that do not indicate DDM support in the ICS value, DDM data is
available although the accuracy of the information has not been validated or verified.
For non-Alcatel-Lucent transceivers, DDM information may be displayed, but Alcatel-Lucent is
not responsible for formatting, accuracy, etc.

Statistics Collection

The DDM information and warnings/alarms are collected at one minute intervals, so the minimum
resolution for any DDM events when correlating with other system events is one minute.
Note that in the Transceiver Digital Diagnostic Monitoring section of the show port port-id detail
command output:
