Cabletron Systems 7000 manual Tip

Alarm Configuration

value provided is SPEL — <IP address> <(hostname)> <date> <time>, where <IP address> and <(hostname)> refer to the workstation that created the alarm and <date> and <time> reflect the date and time of the alarm’s creation.

3.If you are creating a new alarm, use the Index field to assign a unique, currently unused index number to identify the alarm. Clicking on the Index button will automatically assign the lowest available number; you can also click directly in the text box and assign any value you want between 1 and 1,999 and 4,000 and 9,999 (indices 2000 to 3999 are reserved and unavailable).

NOTE

Clicking on the Index button to select the next available index number will replace the current Owner string with the default value described above; if the default value is already in place, the date and time will be updated.

If you wish to modify an existing alarm, enter the appropriate index value, or double-click on the alarm of interest in the Alarms Watch list (in the main Alarm/Event window).

TIP

TIP

Remember, the only thing that determines whether you are modifying an existing alarm or creating a new one is the assignment of the index number; be sure to assign this value appropriately.

4.To select the Variable to be used for your alarm, use the MIBTree panel provided on the right side of the window. (For more information about how to use the MIBTree utility, see the Tools Guide.) The display will default to the top of the tree (labeled Internet); there are two ways to locate and/or assign the correct variable:

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 to move the MIBTree display to that OID. (If MIBTree 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 MIBTree panel 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 donÕt know the exact spelling of the OID you wish to use for your alarm variable, and you canÕt Þnd it by searching through the tree, use the MIBTree utilityÕs Find feature to locate the OID and determine its exact spelling (and tree location). For more information on the MIBTree utility and its Find capabilities, see the Tools Guide.
