Interface Configuration Guide 7705 SAR Interfaces
Edition: 01 3HE 11011 AAAC TQZZA 645
Transceiver Digital Diagnostic Monitoring (DDM), Externally Calibrated
SFP manufacturers specifications guidelines contained
in specification SFF-8472, for the following:
• temperature (C)
• supply voltage (V)
• Tx bias current (mA)
• Tx output power (dBm)
• Rx optical power (avg dBm)
For the above categories, the following values are
shown:
• Value is the current measured value of each variable
• High Alarm is the measurement of Value that will
cause a DDM High Alarm to be output
• High Warn is the measurement of Value that will
cause a DDM High Warning Alarm to be output
• Low Warn is the measurement of Value that will
cause a DDM Low Warning Alarm to be output
• Low Alarm is the measurement of Value that will
cause a DDM Low Alarm to be output
If alarms/warnings are raised, an "!" is included in the
output
Port Statistics
Packets Input/Output The number of packets, delivered by this sublayer to a
higher (sub) layer, which were not addressed to a
multicast or broadcast address at this sublayer. The total
number of packets that higher-level protocols requested
be transmitted, and which were not addressed to a
multicast or broadcast address at this sublayer, including
those that were discarded or not sent.
Discards Input/Output The number of inbound/outbound packets chosen to be
discarded to possibly free up buffer space
