176 CHAPTER 11: RMON COMMANDS
■ rthreshold — Specifies the rising threshold. (Range: 0-2147483647)
■ fthreshold — Specifies the falling threshold. (Range: 0-2147483647)
■ revent — Specifies the event index used when a rising threshold is
crossed.(Range: 1-65535)
■ fevent — Specifies the event index used when a falling threshold is
crossed. (Range: 1-65535)
■ type — Specifies the method used for sampling the selected variable
and calculating the value to be compared against the thresholds.
Possible values are absolute and delta.
If the method is absolute, the value of the selected variable is compared
directly with the thresholds at the end of the sampling interval. If the
method is delta, the selected variable value of the last sample is subtracted
from the current value, and the difference is compared with the thresholds.
■ direction — Specifies the alarm that may be sent when this entry is
first set to valid. Possible values are rising, rising-falling and falling.
If the first sample (after this entry becomes valid) is greater than or equal
to rthreshold and direction is equal to rising or rising-falling, a single
rising alarm is generated. If the first sample (after this entry becomes
valid) is less than or equal to fthreshold and direction is equal to falling or
rising-falling, a single falling alarm is generated.
■ name — Specifies the name of the person who configured this alarm.
If unspecified, the name is an empty string.
Default Configuration
The type is absolute.
The startup direction is rising-falling.
