Device Triggers
To set a trigger for devices, click the Type drop-down list on the System > Triggers > Add page and select one
of the device triggers described in Table 110
For more information on creating a device trigger for hardware errors, see "Triggers for hardware monitoring" on
page 224.
Name Description and Conditions
Device Down This type of trigger activates when an authorized, monitored AP has failed to respond to
SNMP queries from W-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. W-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.
Device Up This trigger type activates when an authorized, previously down AP is now responding to
SNMP queries. To set the conditions for this trigger type, select Add in the Conditions
section.
Configuration
Mismatch
This trigger type activates when the actual configuration on the AP does not match the
defined Group configuration policy.
To set the conditions for this trigger type, select Add in the Conditions section.
AP Usage Activates when the total bandwidth through the device has exceeded a predefined
threshold for more than a specified period (such as more than 1500 Kbps for more than
120 seconds). You can also select bandwidth direction and page/radio. Selecting this type
displays the following new fields in the Type section. Define these settings.
l Alert if AP Usage >= (Kbps)—This threshold establishes a device-specific bandwidth
policy, not a bandwidth policy on the network as a whole.
l Usage Direction—Choose In, Out, or Combined. This bandwidth is monitored on
the device itself, not on the network as a whole.
l Severity - Specify the severity type for the trigger.
l Duration - Specify the time frame for the trigger.
Device Resources This type of trigger indicates that the CPU or memory utilization for a device (including
router or switch) has exceeded a defined percentage for a specified period of time.
