Alarm Configuration
4-10 Advanced Alarm Configuration
The top portion of the Basic Alarm Log window contains the device information
boxes, as well as the Port Number assigned to the interface that experienced the
alarm condition and the type of alarm that was triggered; the remainder of the
window contains the following information about each alarm occurrence:
Index This index number uniquely identifies each occurrence of
a rising or falling event. Note that, since the alarm whose
log is displayed in
Figure 4-2 experienced both rising and
falling alarms, there are two sets of event indices: one
which identifies each instance of the rising alarm, and
one which identifies each instance of the falling alarm.
Time Indicates the date and time of each event occurrence.
Description Provides a detailed description of the condition which
triggered the alarm, including whether it was a Rising or
Falling alarm, the Value which triggered the alarm, and
the configured Threshold that was crossed.
Each log will hold only a finite number of entries, which is determined by the
resources available on the device; when the log is full, the oldest entries will be
replaced by new ones.
Advanced Alarm Configuration
The Basic Alarm Configuration window provides a quick and easy way to set up
some basic alarms for all of the interfaces on your MultiSwitch 700 module.
However, if you prefer more control over the parameters of the alarms you set (as
well as their associated events and actions) and/or a wider array of choices for
each variable, the Advanced Alarm feature provides a powerful and flexible
means for configuring alarms, events, and actions to suit your particular
networking needs.
Accessing the RMON Advanced Alarm/Event List
To access the RMON Advanced Alarm/Event List window:
1. From the Device View, click on the appropriate port interface to display the
Port menu; select Alarm Configuration.
2. In the Basic Alarm Configuration window, click on the Advanced button; the
RMON Advanced Alarm/Event List window,
Figure 4-3 , will appear.
TIP
For more information about the relationship between rising and falling alarms and the
hysteresis function that controls the generation of alarm events, see

Falling Thresholds Work , on page 4-27 .
