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.
