Alarm Configuration

a.If you know the exact name of the OID whose value you wish to track (including its capitalization), simply enter the name in the Alarm Variable field; to verify that you have entered the name correctly, click on the Find->button to move the MIB Tree display to that OID. (If the MIB Tree display does not adjust to show the OID you’ve entered, you’ve entered the name incorrectly; remember, case does count!)

b.Use the scroll bars and click to open the appropriate folders in the MIB Tree display to locate the object you wish you use; click to select it in the panel, and its name will automatically be entered in the Alarm Variable field.

If you don’t know the exact spelling of the OID you wish to use for your alarm variable,

TIP and you can’t find it by searching through the tree, use the MIB Tools utility’s Find feature to locate the OID and determine its exact spelling (and tree location). For more information on the MIB Tools utility and its Find capabilities, see the Tools Guide.

Almost any RMON or MIB-II object can be used as an alarm variable as long as it is resident in the device firmware and its value is defined as an integer (including counters, timeticks, and gauges). If you select an invalid object (i.e., one whose value is not an integer), the message “!!Can’t set alarm on this type!!” will display in the Alarm Variable field.

NOTE

If you select an object which is not resident in the device firmware, you will receive a “Set Failed; ensure variable is readable” message when you try to set your alarm by clicking on the Apply button. If you are unsure just which objects are resident on your device, and you find yourself receiving a lot of “Set Failed” messages, you can use the MIB Tools utility (accessed from the main console window menu bar or from a Device View) to determine which objects are and are not part of your device’s firmware — simply query the object you are interested in; if the query response comes back empty, the object is not present (make sure you are using the appropriate community name when making a query, or you will get no response).

5.Once you have selected the object you wish to use for your alarm variable, you must assign the appropriate instance value in the Alarm Instance field. Most RMON objects are instanced by the index number assigned to the table in which they reside; for example, if you wish to set an alarm on an object located in an RMON Statistics table, you can determine the appropriate instance by noting the index number assigned to the table that is collecting data on the interface you’re interested in. In the case of the default tables, index numbers often mirror interface numbers; however, if there are multiple default tables per interface, or if additional tables have been created, this may not be true. (Table index numbers are assigned automatically as table entries are created; no two tables — even those on different interfaces — will share the same table index number.)
