Alarms

Alarms are predefined conditions based on a rising data threshold, a falling data threshold, or both. You can choose what types of events for which you want the NAM to notify you, and how you want to be notified.

This is the order that you will typically follow for setting up alarms and alarm thresholds:

Step 1 Depending on the type of alarm action you would like to configure, define the way you would like to be notified (by e-mail, trap, trigger capture, or syslog).

•For e-mail server settings: Choose Administration > System > E-Mail Setting

•For trap settings: Choose Administration > System > SNMP Trap Setting

•For capture session settings: Choose Capture > Packet Capture/Decode > Sessions

•For syslog settings: Choose Administration > System > Syslog Setting

Step 2 Define the Alarm Action at Setup > Alarms > Actions.

Step 3 Define the Threshold for this alarm at Setup > Alarms > Thresholds.

The NAM 5.0 Traffic Analyzer menu selections for setting up Alarms are:

•Alarm Actions, page 2-36

•Thresholds, page 2-39

•User Scenario, page 2-49

Alarm Actions

Alarms are predefined conditions based on a rising data threshold, a falling data threshold, or both. You can set thresholds and alarms on various network parameters such as increased utilization, severe application response delays, and voice quality degradation and be alerted to potential problems.

Note NAM 5.0 supports IPv6 for all alarm functionality.
