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 Figure 139. Table 110
itemizes and describes device trigger options and condition settings.
Table 110 Device Trigger Types
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.
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.
Device Client
Count
Activates when a device reaches a user-count threshold for more than a specified period (such as more
than 10 users associated for more than 60 seconds).
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 1500kbps 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.
 Alert if Device Bandwidth >= (kbps)—This threshold establishes a device-specific bandwidth policy, not
a bandwidth policy on the network as a whole.
 Bandwidth Direction—Choose In, Out,orCombined. This bandwidth is monitored on the device itself,
not on the network as a whole.
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.
