6 Click the Start button. Trap Viewer begins to receive traps from the specified
port and community.
The traps when received are listed in the Trap Table. The trap table has the
following five columns.
• Class—defines the severity of the trap.
• Type—defines the type of the trap or the inform request.
• Source—represents the IP address of the source from where the traps were
sent.
• Date—shows the date and time when the trap was received.
• Message—lists the VarBind list of the trap, if any.
The status of the trap is displayed in the status pane at the bottom of the dialog
box. Moreover, the Trap count and the inform count is displayed in the status
pane.
7 To log the received traps, select the Enable Logging check box. All the incoming
traps are logged to a file. The default name of the log file is trap.log.
8 To view the details of the traps, click on the Show Details button. You can also
right-click the trap in the trap table and select View Trap Details.
9 Click Stop to stop listening to the port.
10 To delete a trap, select the trap and click the Delete Entry button. You can also
right-click the trap in the trap table and select Delete the Selected Rows.
Another option in Trap Viewer is the ParserEditor. Trap Viewer can filter the incoming
traps according to certain criterion called the Parser Criteria. The configuration
of the criterion is made possible by using the ParserEditor.
NOTE: To deregister trap receiving, in the snmpTargetAddrTable select the row that corresponds
to the registered trap and then click the Delete button.
Managing Traps
The EMS receives Traps from SNMP agents and converts them to alarms and
non-alarmed events for further processing and reporting.
NOTE: TRAPS are listed with corresponding EMS alarms in “Troubleshooting Alarms” on
page 185.
As some alarms can be enabled or disabled, corresponding traps will accordingly
be enabled or disabled. Thresholds dictate when an enabled trap is activated. For
a list of which alarms can be enabled/disabled, see
“Enable and Disable Host and
Remote Unit Alarms” on page 178.
