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.
