Configuring Radio Settings on an Access Point
How to Configure Radio Settings on an Access Point

• 128 (5640 MHz)
• 132 (5660 MHz)
• 136 (5680 MHz)
• 140 (5700 MHz)
The maximum legal transmit power is greater for some 5-GHz channels than for others. When the access
point randomly selects a 5-GHz channel on which power is restricted, the access point automatically
reduces transmit power to comply with power limits for that channel.
Note 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.

• The interface argument is in module/slot/port format,
except for the Cisco 1800 series fixed-configuration
routers, where the interface argument is either 0 or 1.
• The 5-GHz radio is port 1.
