RMON Configuration Commands
2-10
With an alarm entry defined in an alarm group, a network device performs the following
operations accordingly:
z Sample the defined alarm variables (alarm-variable) once in each specified period,
which is specified by the sampling-time argument.
z Compare the sampled value with the set threshold and perform the corresponding
operations, as described in
Table 2-7.
Table 2-7 Sample value and the corresponding operation
Comparison Operation
The sample value is larger than or equal
to the set upper threshold
(threshold-value1)
Trigger the event identified by the
event-entry1 argument
The sample value is smaller than the set
lower threshold (threshold-value2)
Trigger the event identified by the
event-entry2 argument
 Note:
z Before adding an alarm entry, you need to use the rmon event command to define
the events to be referenced by the alarm entry.
z Make sure the node to be monitored exists before executing the rmon alarm
command.
Examples
# Add the alarm entry numbered 1 as follows:
z The node to be monitored: 1.3.6.1.2.1.16.1.1.1.4.1
z Sampling interval: 10 seconds
z Upper threshold: 50
z The event-entry1 argument identifies event 1.
z Lower threshold: 5
z The event-entry2 argument identifies event 2
z Owner: user1.
