Common Configuration Options
This section describes common configuration options for triggers, reports, and alerts that you might use on a daily basis.
Refer to the following sections for additional information:
l "Which triggers should I set up immediately?" on page 17
l "Which reports should I utilize?" on page 20
l "Which alerts are most important to me?" on page 19
Which triggers should I set up immediately?
AirWave monitors key aspects of wireless LANperformance. When certain conditions or parameters arise that are
outside of normal bounds, AirWave generates (or triggers) alerts that enable you to address problems, often before users
have a chance to report them.
All triggers include an option to configure a Severity Level. This level is tied to the Severe Alert Threshold, which is
configured on the Home > User Info page. This threshold value specifies whether triggers categorized as Critical,
Major, Minor, Warning, or Normal will result in a Severe Alert. If a trigger is defined to result in a Critical alert, and
if the Severe Alert Threshold is defined as Major, then the list of Severe Alerts will include all Major and Critical
alerts. Similarly, if this value is set to Normal, which is the lowest threshold, then the list of Severe Alerts will include
all alerts.
As part of the initial AirWave setup, the following triggers should be configured:
l "Device Down Trigger" on page 17
l "Client Count Trigger" on page 18
l "Radio Noise Floor Trigger" on page 18
l "Rogue Device Classified Trigger" on page 19
Device Down Trigger
This Device Down trigger can alert you to when an authorized, monitored AP has failed to respond to SNMP queries
from AirWave.
Perform the following steps to configure a Device Down trigger.
1. Navigate to the System> Triggers page and click the Add New Trigger button.
2. In the Type drop down, select Device Down.
3. Specify the Severity level for the trigger.
4. Specify whether the trigger should be based on the number of down events over a specified period of time. When this
option 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.
5. Specify whether the Device Down trigger will send alerts for thin APs when the controller is down and whether the
trigger will send alerts when the upstream device is down.
6. Specify whether an alert will be sent if a device is down due to a reboot.
7. Specify the conditions of the trigger and include Device Type and/or Minutes Down criteria.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.
