AP: Unable to set world mode

Question

Cisco recommends using the world-mode dot11d country-code interface configuration command to configure a country code on DFS-enabled radios. The IEEE 802.11h protocol requires access points to include the country information element (IE) in beacons and probe responses. By default, however, the country code in the IE is blank. Use the world-mode command to populate the country code IE.
I'm trying to set world-mode for AP1250 802.11n 5ghz but it doesnt recognize the command.
AP(config-if)#world-mode dot11d US
                                                               ^
% Invalid input detected at '^' marker.
The ^ is under "US"
World-mode country code box is empty on the GUI and the CLI would not accept the command. Any idea on this one?

Hello Derrick,
As per your query i can suggest you the following solution-
When world mode is enabled, the Cisco Access Point (AP) adds channel carrier set information to its beacon. Client devices with world mode enabled receive the carrier set information and adjust their settings automatically. For example, a client device used primarily in Japan can rely on world mode to adjust its channel and power settings automatically when that device travels to Italy and joins a network there. World mode is disabled by default.
For more information on world mode, refer to the Enabling and Disabling World Mode section of Configuring Radio Settings.
For more information on channels and antennas, refer to Channels and Antenna Settings.
Note: The channels are hard-coded on AP chips. The world mode does not change the number of channels that are supported in a country. For example, in the U.S., channel 14 cannot be used even if world mode is configured.
Hope this will work
