4.3.4.1.8.3 RMON Alarm Configuration
RMON Alarm configuration defines specific criteria that will generate response events. It can be set to test data over
any specified time interval and can monitor absolute or changing values. Alarms can also be set to respond to rising or
falling thresholds.
ID:
Indicates the index of the entry. The range is from 1 to 65535.
Interval:
The polling interval for sampling and comparing the rising and falling threshold. The range is from 1to 2^31
seconds.
Variable:
The object number of the MIB variable to be sampled. Only variables of the type ifEntry.n.n may be sampled.
Possible variables are InOctets, InUcastPkts, InNUcastPkts, InDiscards, InErrors, InUnknownProtos, OutOctets,
OutUcastPkts, OutNUcastPkts, OutDiscards, OutErrors, and OutQLen.
Sample Type:
Test for absolute or relative change in the specified variable.
Absolute:
The variable is compared to the thresholds at the end of the sampling period.
Delta:
The last sample is subtracted from the current value and the difference is compared to the thresholds.
Value:
The statistic value during the last sampling period.
Startup Alarm:
Select a method that is used to sample the selected variable and calculate the value to be compared
against the thresholds.
Rising or Falling:
Trigger alarm when the first value is larger than the rising threshold or less than the falling
threshold.
Rising:
Trigger alarm when the first value is larger than the rising threshold.
