sampling-interval: Sets the sampling interval in the range of 5 to 65535 seconds.
absolute: Specifies absolute sampling. RMON compares the value of the variable with the rising and
falling thresholds.
delta: Specifies delta sampling. RMON subtracts the value of the variable at the previous sample
from the current sampled value, and then compares the difference with the rising and falling
thresholds.
startup-alarm: Specifies alarms that can be generated at the first sampling when a rising or falling
threshold is reached or exceeded. By default, a rising-falling alarm is generated.
rising: Generates a rising alarm.
falling: Generates a falling alarm.
rising-falling: Generates a rising or falling alarm.
rising-threshold threshold-value1 event-entry1: Sets the rising threshold. The threshold-value1
argument represents the rising threshold in the range of –2147483648 to 2147483647. The
event-entry1 argument represents the index of the event that is triggered when the rising threshold is
crossed. The value range for the event-entry1 argument is 0 to 65535. If 0 is specified, the alarm
does not trigger any event.
falling-threshold threshold-value2 event-entry2: Sets the falling threshold. The threshold-value2
argument represents the falling threshold in the range of –2147483648 to 2147483647. The
event-entry2 argument represents the index of the event that is triggered when the falling threshold
is crossed. The value range for the event-entry2 argument is 0 to 65535. If 0 is specified, the alarm
does not trigger any event.
owner text: Specifies the entry owner, a case-sensitive string of 1 to 127 characters.
Usage guidelines
You can create a maximum of 60 RMON alarm entries.
Each alarm entry must have a unique alarm variable, sampling interval, sample type, rising threshold,
or falling threshold. You cannot create an alarm entry if all these parameters for the entry are the
same as an existing entry.
To trigger the event associated with an alarm condition, you must create the event with the rmon
event command.
RMON samples the monitored alarm variable at the specified sampling interval, compares the
sampled value with the predefined thresholds, and performs one of the following operations:
•
Triggers the event associated with the rising alarm if the sampled value is equal to or greater
than the rising threshold.
•
Triggers the event associated with the falling alarm if the sampled value is equal to or less than
the falling threshold.
Examples
# Create an alarm entry to perform absolute sampling on the number of octets received on
Ten-GigabitEthernet 1/0/1 (object instance 1.3.6.1.2.1.16.1.1.1.4.1) at 10-seconds intervals. If the
sampled value reaches or exceeds 5000, log the rising alarm event. If the sampled value is equal to
or less than 5, take no actions.
