WLAN Profiles
WLAN Profiles are used to configure the WLAN settings for devices utilizing your network. After
creating a WLAN Profile using the New Profile button, it can be applied by selecting the profile and
clicking the Apply button. When a WLAN Profile is applied to your system, if the WLAN thresholds for
that profile are exceeded, a security alarm is generated. If there are no WLAN Profiles applied to your
system, no alarms are generated. There are two tabs associated with WLAN Profiles: General and
Security.
General Tab
