Chapter 7 Controlling Lightweight Access Points

Configuring Country Codes

Generally, you configure one country code per controller, the one matching the physical location of the

controller and its access points. However, controller software release 4.1 or later allows you to configure

up to 20 country codes per controller. This multiple-country support enables you to manage access points

in various countries from a single controller.

Note Although the controller supports different access points in different regulatory domains (countries), it

requires all radios in a single access point to be configured for the same regulatory domain. For example,

you should not configure a Cisco 1231 access point’s 802.11b/g radio for the US (-A) regulatory domain

and its 802.11a radio for the Great Britain (-E) regulatory domain. Otherwise, the controller allows only

one of the access point’s radios to turn on, depending on which regulatory domain you selected for the

access point on the controller. Therefore, make sure that the same country code is configured for both of

the access point’s radios.

Guidelines for Configuring Multiple Country Codes

Follow these guidelines when configuring multiple country codes:

• The multiple-country feature is not supported for use with Cisco Aironet mesh access points. If a

mesh access point is already connected to the controller, multiple-country configuration is rejected.

If multiple-country support is configured, mesh access points are not permitted to join the controller.

• When the multiple-country feature is being used, all controllers intended to join the same RF group

must be configured with the same set of countries, configured in the same order.

• When multiple countries are configured and the radio resource management (RRM) auto-RF feature

is enabled, the auto-RF feature is limited to only the channels that are legal in all configured

countries and to the lowest power level common to all configured countries. The access points are

always able to use all legal frequencies, but non-common channels can only be assigned manually.

Note If an access point was already set to a higher legal power level or is configured manually,

the power level is limited only by the particular country to which that access point is

assigned.

• When multiple countries are configured, the 802.11a network is disabled for all countries if any

country does not support the 802.11a radio or there are no common channels on the 802.11a radio.

You can configure country codes through the controller GUI or CLI.

Using the GUI to Configure Country Codes

Follow these steps to configure country codes using the GUI.

Step 1 Follow these steps to disable the 802.11a and 802.11b/g networks:

a. Click Wireless > 802.11a/n > Network.

b. Uncheck the 802.11a Network Status check box.
