PARAMETERS
These parameters are displayed:
◆ Port – Port number. (Range: 1-28)
◆ General – Information on connector type and vendor-related
parameters.
◆ DDM Information – Information on temperature, supply voltage,
laser bias current, laser power, and received optical power.
The switch can display diagnostic information for SFP modules which
support the SFF-8472 Specification for Diagnostic Monitoring Interface
for Optical Transceivers. This information allows administrators to
remotely diagnose problems with optical devices. This feature, referred
to as Digital Diagnostic Monitoring (DDM) provides information on
transceiver parameters.
◆ Trap – Sends a trap when any of the transceiver’s operation values
falls outside of specified thresholds. (Default: Disabled)
◆ Auto Mode – Uses default threshold settings obtained from the
transceiver to determine when an alarm or trap message should be
sent. (Default: Enabled)
◆ DDM Thresholds – Information on alarm and warning thresholds. The
switch can be configured to send a trap when the measured parameter
falls outside of the specified thresholds.
The following alarm and warning parameters are supported:
â–
High Alarm – Sends an alarm message when the high threshold is
crossed.
â–
High Warning – Sends a warning message when the high
threshold is crossed.
â–
Low Warning – Sends a warning message when the low threshold
is crossed.
â–
Low Alarm – Sends an alarm message when the low threshold is
crossed.
The configurable ranges are:
â–
Temperature: -200.00-200.00 °C
â–
Voltage: 1.00-255.00 Volts
â–
Current: 1.00-255.00 mA
â–
Power: -99.99-99.99 dBm
