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 or 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. For more information on Processed Traps, see:

•Processed Standard SNMP Traps (RFC 1215)

•Processed CISCO-STACK-MIB Traps

•Processed CISCO-ISDN-MIB Traps

•Processed CISCO-ENTITY-FRU-CONTROL-MIB Trap

Pass-Through SNMP Unidentified Traps

Pass-through traps are the traps that are generated from devices and are not processed by DFM. The traps appear in the alerts and activities page, if they are generated from the devices that are managed by DFM. DFM cannot process these traps and map them to a topology element such as cards and interfaces. However, DFM can forward the traps irrespective of the device state is either managed or unmanaged. Forwarding these traps is controlled using Configuration > Other Configurations > SNMP Trap Forwarding.

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

---

Note Pass-through traps will be cleared after a default interval of 10 minutes to one hour. 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. To get more information on an Unidentified Trap see the corresponding Events page.

Clearing an Unidentified Trap

You can manually clear Unidentified Traps from the DFM. To do this:

---

Step 1 Select the Unidentified Trap and click Clear

A message appears prompting you to confirm the clearing

Step 2 Enter your user ID.

This will be used as a reference to identify who cleared the Unidentified Trap.

Step 3 Click OK to confirm

The Unidentified trap is cleared

To retain the trap click Cancel .
