Digital Diagnostic Monitoring (DDM) allows the Avaya Ethernet Routing Switch 8800/8600 to
monitor SFP and XFP laser operating characteristics. Avaya Ethernet Routing Switch
8800/8600 also supports Digital Diagnostic Interfaces (DDI), which is an interface that supports
DDM. DDI involves data collection and alarm and warning monitoring.
Important:
DDI data for pluggables with the same part number can vary. When you view DDI data for
pluggables through the CLI show sys pluggable command or through EDM, you may
see some differences in the high and low threshold and alarm values programmed between
pluggables. These differences are normal and are to be expected. However, all Avaya
branded pluggables meet or exceed the Avaya minimum tolerances and standards.
Static data collection includes SFP vendor information, DDI support information, and DDI alarm
and warning threshold values. Dynamic data collection includes temperature, supply voltage,
laser bias current, transmit power, and receive power. DDM works at any time during active
laser operation without affecting data traffic.
The switch only checks warning and alarm status bits during initialization and during requests
for dynamic data. If an alarm or warning is asserted or cleared, the switch logs a message and
generates a trap. The switch maps DDM warning and alarm messages into Warning and Fatal
message categories for system logging purposes. If you activate the ddm-alarm-portdown
option, DDI shuts down the corresponding port if a high or low alarm occurs on the port.
For more information about how to configure DDM, see Avaya Ethernet Routing Switch
8800/8600 Performance Management, NN46205-704.
The SFPs described in this section are all RoHS -E6 compliant.
The following tables list and describes the Avaya SFP models with DDI capability. All the optical
SFPs use LC connectors.
