Displaying SFP DDM and Inventory Information
Static and dynamic monitoring is available for SFP modules, including all SFP,
SFP+, and CSFP modules used in Ethernet and MIMO ports in IP-20 all-outdoor
products.
Dynamic monitoring (DDM) PMs are also available, but only via the CLI. For
details, see
Displaying SFP DDM and Inventory Information (CLI)
Note:
DDM parameters are not relevant for electrical SFPs.
The following alarms are available in connection with SFP DDM and inventory
monitoring. The polling interval for these alarms is one minute.
•
Alarm #803- SFP port RX power level is too low.
•
Alarm #804
–
SFP port RX power level is too high.
•
Alarm #805- SFP port TX power level is too low.
•
Alarm #806
–
SFP port TX power level is too high.
These alarms are based on thresholds defined by the SFP module vendor, which
are static. They also display the actual RX or TX values as of the time when the
alarm was raised, which are dynamic. The dynamic values are not changed as long
as the alarm is still raised. They are only updated if the alarm is cleared, then
raised again.
If there is no signal on the interface, a Loss of Carrier alarm (LOC) is raised, and
this alarm masks the DDM alarms.
