◆ 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:
■
High Alarm – Sends an alarm message when the high threshold is crossed.
■
High Warning – Sends a warning message when the high threshold is
crossed.
■
Low Warning – Sends a warning message when the low threshold is
crossed.
■
Low Alarm – Sends an alarm message when the low threshold is crossed.
The configurable ranges are:
■
Tempe rat ure: -128.00-128.00 °C
■
Voltage: 0.00-6.55 Volts
■
Current: 0.00-131.00 mA
■
Power: -40.00-8.20 dBm
The threshold value for Rx and Tx power is calculated as the power ratio in
decibels (dB) of the measured power referenced to one milliwatt (mW).
Threshold values for alarm and warning messages can be configured as
described below.
■
A high-threshold alarm or warning message is sent if the current value is
greater than or equal to the threshold, and the last sample value was less
than the threshold. After a rising event has been generated, another such
event will not be generated until the sampled value has fallen below the
high threshold and reaches the low threshold.
■
A low-threshold alarm or warning message is sent if the current value is less
than or equal to the threshold, and the last sample value was greater than
the threshold. After a falling event has been generated, another such event
will not be generated until the sampled value has risen above the low
threshold and reaches the high threshold.
■
Threshold events are triggered as described above to avoid a hysteresis
effect which would continuously trigger event messages if the power level
were to fluctuate just above and below either the high threshold or the low
threshold.
■
Trap messages configured by this command are sent to any management
station configured as an SNMP trap manager using the Administration >
SNMP (Configure Trap) page.
