Chapter Configuring Radio Settings
Enabling and Disabling World Mode
SUMMARY STEPS
1. configure terminal
2. interface dot11radio {0| 1}
3. world-mode {dot11d country_code code {both | indoor | outdoor} | world-mode roaming |
legacy}
4. end
5. copy running-config startup-config
DETAILED STEPS
Use the no form of the world-mode command to disable world mode.
Command Purpose
Step 1
configure terminal Enters global configuration mode.
Step 2
interface dot11radio {0| 1} Enters interface configuration mode for the radio interface.
Step 3
world-mode
{dot11d country_code code
{both | indoor | outdoor}
| world-mode roaming | legacy}
Enables world mode.
• Enter the dot11d option to enable 802.11d world mode.
– When you enter the dot11d option, you must enter a
2-character ISO country code (for example, the ISO
country code for the United States is US). You can find
a list of ISO country codes at the ISO website.
– After the country code, you must enter indoor,
outdoor, or both to indicate the placement of the
wireless device.
• Enter the legacy option to enable Cisco legacy world
mode.
• Enter the world-mode roaming option to place the access
point in a continuous world mode configuration.
Note Aironet extensions must be enabled for legacy world
mode operation, but Aironet extensions are not
required for 802.11d world mode. Aironet extensions
are enabled by default.
Step 4
end Returns to privileged EXEC mode.
Step 5
copy running-config startup-config (Optional) Saves your entries in the configuration file.
