SNMP traps capture system monitoring information in Data ONTAP. There are two types of traps in Data ONTAP:
built-in and user-defined.
- Built-in traps are predefined in Data ONTAP and are automatically sent to the network management stations on the traphost list if an event occurs. These traps are based on one of the following:
- RFC 1213, which defines traps such as coldStart, linkDown, linkUp, and authenticationFailure.
- Specific traps defined in the custom MIB, such as diskFailedShutdown, cpuTooBusy, and volumeNearlyFull.
- User-defined traps are defined by snmp traps commands or the FilerView SNMP Traps windows. These traps are sent using proxy trap ID numbers 11 through 18, which correspond to a trap's MIB priority.
