About user-defined traps

You can create custom SNMP traps to send specific types of information to your network management station. To create a trap, you need to determine the information you want the trap to report on, and then determine the MIB variable that tracks that information.

Identifying a MIB variable to be used with a new trap

The NetApp MIB lists available variables with short descriptions. You can locate the MIB variable from the MIB on the NetCache CD-ROM or from the NOW Web page. However, it is easier to use the SNMP MIB browser in the Appliance Manager to select a variable and the object identifier (OID) associated with it.

Using the MIB browser in the Appliance Manager provides the following benefits:

It presents the MIB variable information in an orderly, readable manner.
When you click on the object name, the trap OID for the selected variable is imported directly into the New SNMP Traps page. You do not have to type the trap parameters into the page yourself, which is required if you look for this information in the MIB on the CD-ROM or on the NOW site.

To access the SNMP MIB browser, select Setup tab > Administration > SNMP in the Appliance Manager. Then click Show MIB Browser at the bottom of the page.
