NOTE: ChannelFly channel selection data is persistent across reboots for the
following APs only: 7982, 7782, 7782-x, 7781-CM, SC-8800-S. It is not persistent
across power cycles for any AP.
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 ZoneDi-
rector 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 that Background Scanning must be
enabled for ZoneDirector to detect rogue APs on the network.
To configure Background Scanning:
1 Go to Configure > Services .
2 In the Background Scanning section, configure the following options:
• Run a background scan on the 2.4 GHz radio every [ ] : Select this check
box enter the time interval (1~65535 seconds, default is 20) that you want to
set between each scan.
• Run a background scan on the 5 GHz radio every [ ] : Select this check
box enter the time interval (1~65535 seconds, default is 20) that you want to
set between each scan.
NOTE: If you want to disable Background Scanning, clear the check box; this
should result in a minor increase in AP performance, but removes the detection of
rogue APs from ZoneDirector monitoring. You can also decrease the scan frequency,
as less frequent scanning improves overall AP performance.
