Trigger Option Description
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.
Device Event
This trigger is used for alerting based on SNMP traps and syslog messages, which are
displayed in System > Syslogs & Traps, APs/Devices > Monitor for affected devices, and in
Clients > Client Detail. The conditions supported are:
l Event Contents (case insensitive substring matches on message content)
l Event Type (syslog or trap)
l Syslog Severity: Emergency, Alert, Critical, Bug, Error, Warning, Notice, or Info
l Syslog Category
l SNMP Trap Category: Hardware, IDS, Client Security, AP Security, AP Status, Software,
or Rogue Detection
l Syslog Category
NOTE: During the process of upgrading or installation for non-Master Console/Failover
AirWaves, AirWave creates two default trigger definitions for Device Events:
l SNMP Trap Category of Hardware or Software
l Event Type is Syslog and Syslog Severity >= Critical
Device Uplink
Status
This trigger deploys whenever a RAP’s active uplink changes from Ethernet to USB or vice
versa. The corresponding events are captured in a RAP’s APs/Devices > Monitor page.

2. Repeat this procedure for as many triggers and conditions as desired. Refer to the start of "Creating New Triggers" on
page 220 to create a new trigger.
Setting Triggers for Interfaces and Radios
To configure radio- and interface-related triggers, choose a trigger type from the Interfaces/ Radios category, listed in
the Type drop-down menu. Table 111 itemizes and describes the radio trigger types and condition settings.
