Chapter 6 Configuring Remote Monitoring (RMON)
Defining a Falling Threshold and Index
Note
OL-5647-02
If you want to be notified when a sampling is less than or equal to a specific
number, set a falling threshold and associate it to a configured event.
You must create an RMON event before you can associate it with an alarm.
For a single falling alarm event to occur, a sampled value is less than or equal to
the falling threshold value, and the value at the last sampling interval is greater
than this threshold.
• Use the falling-threshold falling_value command to set the threshold for the
alarm. The falling_value variable is the threshold for the falling sample type.
Enter an integer from 0 (default) to 4294967295.
To set the falling threshold value of 90, enter:
(config-rmonalarm[1])# falling-threshold 90
To reset the falling threshold to 0, enter:
(config-rmonalarm[1])# no falling-threshold
Use the falling-event falling_index command to associate a configured event
•
to the RMON alarm when the sampled value exceeds the falling threshold
value. The falling_index variable is the event index used when a falling
threshold is crossed. Enter a previously created RMON event index (see the
"Creating an Index for an RMON Event"
generated.
To associate the threshold to RMON event 2, enter:
(config-rmonalarm[1])# falling-event 2
To see a list of RMON events, enter:
(config-rmonalarm[1])# falling-event ?
To reset the falling event to 0, enter:
(config-rmonalarm[1])# no falling-event
section). If you enter 0, no event is
