Setting Triggers For Devices - Dell PowerConnect W-AirWave 7.6 User Manual

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.
If you select Email, you are prompted to set the sender and recipient email addresses.
l
If you select NMS, you are prompted to choose one or more of the pre-defined trap destinations, which
l
are configured on the AMP Setup >NMS page. Note that this option is only available if an NMS server
has been added to AirWave.
Define the Logged Alert Visibility, in which you can choose how this trigger is distributed. The trigger
l
can distribute according to how is it generated (triggering agent), or by the role with which it is
associated.
The Suppress Until Acknowledged setting defines whether the trigger requires manual and administrative
l
acknowledgement 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.
a. Choose a device type from the Devices listed in the Type drop-down menu. See
itemizes and describes device trigger options and condition settings.
Table 106:
Device Trigger Types
Device Down
Device Up
194 | Performing Daily Administration in AirWave
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.
This trigger type activates when an authorized, previously down AP is now responding to SNMP queries.
