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

---

For some SNMP traps, IP Telephony Monitor (ITM) either processes them or treats them as pass-through traps. Pass-through traps are placed into an "Unidentified Trap" group, or bucket. In other words, ITM displays pass-through traps in the Alerts and Activities display with both a device type and the event name "Unidentified Trap."

The bucket is also the holding place for other unusual traps and events. These traps and events, and how ITM treats them, are described in these topics:

•Processed SNMP Traps

•Pass-Through SNMP Unidentified Traps

•Other Unidentified Traps and Events

Processed SNMP Traps

When ITM 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."

Pass-Through SNMP Unidentified Traps

Pass-through traps are traps that ITM receives from devices that are not in the ITM 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 name "Unidentified Trap."

Because ITM cannot identify these traps as being sent from devices being managed by ITM, they are displayed in the All Alerts view. If you are using ITM Multi-View, these traps are displayed in the All Alerts view of every active partition.

---

Note Not all events that fall under Unidentified Trap are pass-through traps. See the "Other Unidentified Traps and Events" section.

To view the actual trap in the event properties display, follow this procedure.

---

Step 1 Locate the alert ID for the unidentified trap in the Alerts and Activities display, as shown in the last line of Figure B-1.

Figure B-1 Alerts and Activities Display—Unidentified Pass-Through Trap

Step 2 Click the alert ID corresponding to the unidentified trap. The Alerts and Activities Detail page appears, as shown in Figure B-2.

Step 3 Click the event ID. The event properties page appears, displaying information about the pass-through trap.

Other Unidentified Traps and Events

The Unidentified Trap bucket may contain non-pass-through traps, along with other unexpected ITM events. This can happen under the following circumstances:

•When an event occurs on a device that is being discovered by ITM.

•When ITM encounters problems in its operation.

•When the ITM server is busy, and confidence tests cannot run. (The ConfidenceTestNotRun event is displayed as an Unidentified Trap because it does not relate to a specific device.)
