Chapter 7 Controlling Lightweight Access Points

Migrating Access Points from the -J Regulatory Domain to the -U Regulatory Domain

The Japanese regulations allow the regulatory domain that is programmed into an access point’s radio to

be migrated from the -J domain to the -U domain. New access points for the Japanese market contain

radios that are configured for the -P regulatory domain. -J radios are no longer being sold. In order to

make sure that your existing -J radios work together with the new -P radios in one network, you need to

migrate your -J radios to the -U domain.

Country codes, as explained in the previous section, define the channels that can be used legally in each

country. These country codes are available for Japan:

• JP—Allows only -J radios to join the controller

• J2—Allows only -P radios to join the controller

• J3—Uses the -U frequencies but allows both -U and -P radios to join the controller

Note After migration, you need to use the J3 country code. If your controller is running software

release 4.1 or later, you can use the multiple-country feature, explained in the previous

section, to choose both J2 and J3. Then you can manually configure your -P radios to use the

channels not supported by J3.

Refer to the Channels and Maximum Power Settings for Cisco Aironet Lightweight Access Points

document for the list of channels and power levels supported by access points in the Japanese regulatory

domains.

Guidelines for Migration

Follow these guidelines before migrating your access points to the -U regulatory domain:

• You can migrate only Cisco Aironet 1000, 1130, 1200, and 1240 lightweight access points that

support the -J regulatory domain and Airespace AS1200 access points. Other access points cannot

be migrated.

• Your controller and all access points must be running software release 4.1 or greater or software

release 3.2.193.0.

Note Software release 4.0 is not supported. If you migrate your access points using software

release 3.2.193.0, you cannot upgrade to software release 4.0. You can upgrade only to

software release 4.1 or later or to a later release of the 3.2 software.

• You must have had one or more Japan country codes (JP, J2, or J3) configured on your controller at

the time you last booted your controller.

• You must have at least one access point with a -J regulatory domain joined to your controller.

• You cannot migrate your access points from the -U regulatory domain back to the -J domain. The

Japanese government has made reverse migration illegal.

Note You cannot undo an access point migration. Once an access point has been migrated, you

cannot return to software release 4.0. Migrated access points will have non-functioning

802.11a radios under software release 4.0.
