Background Scanning
Using Background Scanning, ZoneDirector regularly samples the activity in all Access
Points to assess RF usage, to detect rogue APs and to determine which APs are near
each other for mesh optimization.
These scans sample one channel at a time in each AP so as not to interfere with network
use. This information is then applied in AP Monitoring and other ZoneDirector monitoring
features. You can, if you prefer, customize the automatic scanning of RF activity,
deactivate it if you feel it's not helpful, or adjust the frequency, if you want scans at
greater or fewer intervals.
NOTE
Background Scanning must be enabled for ZoneDirector to detect rogue APs
on the network.
Background Scanning can be configured independently for the 2.4 and 5 GHz radios.
Additionally, you can configure the frequency at which scans are run.
