For each WiFi band, the following applies:
Y
ou can remove one or more channels from the list of available
channels by clearing their check boxes. For example, you might
want to avoid interference with competing equipment such as in
a medical environment in which medical devices use a specific
channel.
You cannot add channels.

6. To preview the best channels for all the managed access points, click the Preview button.
A pop-up window shows the list of allocated channels. The selected channels are not
applied to the managed access points (it is just a preview of what happens if you click the
Run now button). Access points for which you override the channel and frequency (see
Override the Channel and Frequency for an Access Point on page 206
) are not displayed
in the pop-up window.
Dynamic Frequency Selection (DFS) channels are mostly used
for weather-radar and military applications. DFS regulations
depend on the country or region. We recommend that you read
the DFS regulations before you use any DFS channels.
Note: If the wireless controller is
prevented from reallocating a channel
because it is in use, the wireless
controller checks again at the next
scheduled channel allocation.
Note: We recommend that you
schedule channel allocation once a
day at times when the fewest clients
are expected to be connected.
