Processed and Pass-Through Traps, and Unidentified Traps and Events

---

For some SNMP traps, Device Fault Manager (DFM) either processes them or treats them as pass-through traps. These traps, and how DFM treats them, are described in these topics:

•Processed SNMP Traps

•Pass-Through SNMP Unidentified Traps

•Unidentified Traps

Processed SNMP Traps

When DFM receives certain SNMP traps, it analyzes the data found in the following fields of each SNMP trap message, and changes the property value of the object property (if required):

•Enterprise (the sysObjectID of the agent/object)

•Generic Trap Identifier

•Specific Trap Identifier

•Variable-Bindings

•IP address of the SNMP agent

---

Note Use Notification Services to forward specific traps to e-mail recipients or host machines. See Using Notification Services

---

All processed traps are forwarded in V1 format.

Pass-Through SNMP Unidentified Traps

Pass-through traps are traps that DFM receives from devices that are not in the DFM inventory. These traps are shown in the Alerts and Activities display because of their relevance to fault monitoring. Pass-through traps are displayed as follows:

•As one of the following events:

–InformAlarm

–MinorAlarm

–MajorAlarm

•With the device type and the device name from which it was generated

If DFM does not know which device generated the trap, it ignores the trap.

Unidentified Traps

DFM may display an event as an Unidentified Trap. Normally an Unidentified Trap is reported when an event occurs on a device that is being discovered by DFM. You can get more information on an Unidentified Trap by looking at its Events page.
