Alarm Manager example

Note: The example alarm described in the following procedure generates at least one alarm every five minutes. The example is intended only to demonstrate how alarms fire; it is not a useful alarm. Because of the high frequency, you may want to delete this alarm and replace it with a practical setting.

To create an alarm to receive statistics and history using default values:

1. Do one of the following:
• From the Device Manager main menu, choose RMON >Alarm Manager.
• On the toolbar, click the Alarm Manager button.

The Alarm Manager dialog box opens.

2. In the variable field, select a variable for the alarm from the list and a port (or other ID) on which you want to set an alarm.

Alarm variables are in three formats, depending on the type:

• A chassis alarm ends in .x where the x index is hard-coded. No further information is required.
• A card, spanning tree group (STG) or EtherStat alarm ends with a dot (.). You must enter a card number, STG ID, IP address, or EtherStat information.
• A port alarm ends with no dot or index and requires using the port shortcut menu. An example of a port alarm would be ifInOctets (interface incoming octet count).

For this example, select Bridge > dot1dStpTopChanges.0 from the variable list. This example is a chassis alarm, indicated by the ".0" in the variable.

3. For this example, select a rising value of 4 and a falling value of 0.
4. Leave the remaining fields at their default values, including a sample type of Delta.
5. Click Insert.
