Alarm Configuration

Before you decided whether or not to assign an action to a rising or falling alarm, it is

TIP important to understand something about the hysteresis function built in to the RMON alarm functionality. See How Rising and Falling Thresholds Work, page 3-27, for more information.

The remainder of the window fields provide the means for configuring alarms for each available interface. Note that the information provided in this screen is static

once it is displayed; for updated information, click on . Adding or modifying an alarm automatically updates the list.

Creating and Editing a Basic Alarm

The editable fields at the bottom of the Basic Alarm Configuration window allow you to configure alarm parameters for each available interface. These fields will display the parameters used for the most recently configured alarm (no matter which interfaces are selected in the list box); this allows you to set the same parameters on multiple interfaces with a single set. Hold down the Shift key while clicking to select a contiguous group of interfaces; use the Ctrl key to select any interfaces. To display the alarm parameters for a specific interface, double-click on that interface.

Note that there is no specific “Enable” function; simply configuring thresholds and/or actions for an alarm and applying those changes enables the alarm. For more information on disabling an alarm, see Disabling a Basic Alarm, page 3-9.

To configure an alarm:

1.At the top of the window, click to select the variable to be used for your alarm: Kilobits, Total Errors, or Broadcast/Multicast. The display in the list box will reflect the current status at each interface of the alarm type you have selected.

2.In the list box, click to highlight the interface (or use shift-clickor ctrl-clickto select multiple interfaces) for which you would like to configure an alarm for the selected variable. Note that the editable fields will display the parameters assigned to the most recently set alarm; however, any changes you make in these fields will be set to all selected interfaces.

3.In the Interval field, enter the amount of time, in seconds, over which the selected variable will be sampled. At the end of the interval, the sample value will be compared to both the rising and falling thresholds. You can assign any interval from 1 to 65,535.

4.In the Alarm field, click to select one or both of the following options:

a.Select Log if you wish to create a silent log of alarm occurrences.

b.Select Trap if you want your device to issue a trap in response to each alarm occurrence.
