+2,147,483,647 and event-entry2 represents the index of the event triggered when the
falling threshold is reached. It ranges from 1 to 65,535.
forever: Indicates that the lifetime of the private alarm entry is infinite.
cycle cycle-period: Sets the lifetime period of the private alarm entry, in the range 0 to
2,147,483,647 seconds.
owner text: Owner of the entry, a string of 1 to 127 characters. It is case sensitive and
space is supported.
Description
Use the rmon prialarm command to create an entry in the private alarm table of
RMON.
Use the undo rmon prialarm command to remove a private alarm entry from the
private alarm table of RMON.
The following is how the system handles private alarm entries:
1) Samples the private alarm variables in the private alarm formula at the specified
sampling interval.
2) Performs calculation on the sampled values with the formula.
3) Compares the calculation result with the predefined thresholds and does the
following:
If the rising threshold is reached, triggers the event specified by the event-entry1
argument.
If the falling threshold is reached, triggers the event specified by the event-entry2
argument.
Note:
Before creating an alarm entry, define the events to be referenced in the event table
with the rmon event command.
When you create an entry, if the values of the specified alarm variable formula
(prialarm-formula), sampling type (absolute changeratio or delta), rising threshold
(threshold-value1) and falling threshold (threshold-value2) are identical to those of
the existing alarm entry, the system considers their configurations the same and the
creation fails.
You can create up to 50 pri-alarm entries.
The rising alarm and falling alarm are alternate.
Examples
# Create entry 5 in the private alarm table. Calculate the private alarm variables with the
(1.3.6.1.2.1.16.1.1.1.4.1*100) formula and sample the corresponding variables at
