b. The Alert Notifications settings section allows you to enter a note that will be included with the alert. This note

will appear with the alert on the System > Alerts page. The Alert Notification section also allows you to specify

whether the alert will be distributed via email, to a network management system (NMS), or to both.

n If you select Email, you are prompted to set the sender and recipient email addresses.

n If you select NMS, you are prompted to choose one or more of the pre-defined trap destinations, which are

configured on the AMP Setup >NMS page. Note that this option is only available if an NMS server has been

added to AirWave.

n Define the Logged Alert Visibility, in which you can choose how this trigger is distributed. The trigger can

distribute according to how is it generated (triggering agent), or by the role with which it is associated.

n The Suppress Until Acknowledged setting defines whether the trigger requires manual and administrative

acknowledgment to gain visibility. If No, a new alert will be created every time the trigger criteria are met. If

Yes, an alert will only be received the first time the criteria is met. A new alert for the device is not created

until the initial one is acknowledged.

Repeat this procedure for as many triggers and conditions as desired.

Complete the creation of your trigger type using one of the following procedures for each trigger:

Setting Triggers for Devices

Perform the following steps to configure device-related triggers.

1. Choose a device type from the Devices listed in the Type drop-down menu. See Figure 130 in "Creating New

Triggers" on page 220. Table 110 itemizes and describes device trigger options and condition settings.

Trigger Option Description

Device Down

This is the default type whenever configuring a new trigger. This type of trigger activates

when an authorized, monitored AP has failed to respond to SNMP queries from AirWave.

To set the conditions for this trigger type, select Add in the Conditions section. Complete

the conditions with the Option, Condition, and Value drop-down menus. The conditions

establish the device type. Multiple conditions can apply to this type of trigger. The Device

Down trigger can be configured to send alerts for thin APs when the controller is down; this

behavior is turned off by default.

Triggers with the Minutes Down condition enabled will compare the amount of time an AP

has been down to the value (in minutes) set for the condition.

When the Limit by number of down events is enabled, you can set the number of down

events that activate the trigger, as well as the duration of the time window to be measured.

AirWave will then count the number of times that the device has gone from Up to Down in

the specified span of time and display this in the Device Down alert.
