Wireless Controller
Configure Automatic Channel Allocation
Automatic channel allocation distributes channels across the managed access points to
reduce interference. Each wireless controller allocates channels for its managed access
points, regardless of their configured security profiles. The wireless controller detects
interference, traffic load on the access point, and neighborhood maps to determine the best
channel for an access point. The wireless controller collects this information over the
previous 24 hours and uses this information to determine the best possible channel for the
access point.
Note: The wireless controller determines available channels based on the
country or region that you specified on the General Settings page
(see Configure the General Settings on page 101).
You can configure channel allocation to allow allocation of only the specified channels when
channel allocation is scheduled to run. Channel allocation ensures that the access points use
only the channels allowed according to administration policies.
To adhere to best practices when adjusting channel allocation, we recommend the following:
Select channels that do not overlap. For example, for 2.4 GHz, use channels 1, 6, and 11.
Schedule channel allocation once a day at times when the fewest clients are expected to
be connected.
Channel allocation is a global feature that applies to all access points. (If you disable channel
allocation, it is globally disabled for all access points.)
The allocated channels also apply to
all access points, irrespective of whether they are managed in the basic profile group or an
advanced profile group.
However
, you can override the general channel allocation settings for individual access
points on the Basic Wireless Settings page and on the Advanced Wireless Settings page. For
more information, see
Override the Channel and Frequency for an Access Point on
page 206.
CAUTION:
Automatic channel allocation enabled by default. We recommend that you
do not disable automatic channel allocation unless you are debugging or
an extreme situation occurred that affects the channels.
