2-13
threshold-value2: Lower threshold, in the range 0 to 2147483647.
event-entry2: Index of the event entry that corresponds to the falling threshold, in the range 0 to 65535.
forever: Specifies the corresponding RMON alarm instance is valid permanently.
cycle: Specifies the corresponding RMON alarm instance is valid periodically.
cycle-period: Life time (in seconds) of the RMON alarm instance, in the range 0 to 2147483647.
owner text: Specifies the owner of the alarm entry, a string of 1 to 127 characters.
Description
Use the rmon prialarm command to create an extended entry in an extended RMON alarm table. If you
do not specify the owner text keyword/argument combination, the owner of the entry is displayed as
“null”.
Use the undo rmon prialarm command to remove an extended alarm entry.
z Before adding an extended alarm entry, you need to use the rmon event command to define the
events to be referenced by the entry.
z Make sure the node to be monitored exists before executing the rmon event command.
z You can define up to 50 extended alarm entries.
With an extended alarm entry defined in an extended alarm group, the device performs the following
operations accordingly:
z Sampling the alarm variables referenced in the defined extended alarm expression
(prialarm-formula) once in each period specified by the sampling-timer argument.
z Performing operations on the sampled values according to the defined extended alarm expression
(prialarm-formula)
z Comparing the operation result with the set thresholds and perform corresponding operations, as
described in
Table 2-8.
Table 2-8 Operation result and corresponding operation
Comparison Operation
The operation result is larger than or equal to the
set upper threshold (threshold-value1)
Triggering the event identified by the
event-entry1 argument
The operation result is smaller than or equal to
the set lower threshold (threshold-value2)
Triggering the event identified by the
event-entry2 argument
Examples
# Add the extended alarm entry numbered 2 as follows:
z Perform operations on the corresponding alarm variables using the expression
((1.3.6.1.2.1.16.1.1.1.4.1)*100).
z Sampling interval: 10 seconds
z Rising threshold: 50
