Configuring an AP’s Radio Channels

Set a Radio to Support 802.11n Only with the CLI

To set an AP320 radio interface to support only 802.11n clients, and thus improve

throughput, from the Dot11Radio interface configuration mode use the command:

n-only-mode

To disable the 802.11n-only support, use the command:

no n-only-mode

Note that All APs on the same channel in a Virtual Cell must have the same setting

for n-only mode.

Configuring an AP’s Radio Channels

AP channel configuration is configurable for 802.11bg which consists of 11 overlap-

ping channels in United States deployments. Channel configuration for 802.11a is not

an issue because there are no overlapping channels within the 802.11a spectrum.

In the 802.11b/g standard, there are 14 channels. As a result of FCC rules, there are

11 channels: channels 1 through 11 are used in the USA. Other countries may also use

channels 12, 13, and 14. These channels represent the center frequency of the wire-

less transmission wave. In practice, 802.11bg has only three operational frequencies

in a given area, and most deployments use channels 1, 6, and 11, for which there is

no overlap.
