Cisco AP541N Dual-band Single-radio Access Point Quick Start Guide

The country in which the access point is operating. 

Wireless regulations vary from country to country. Make sure 
you select the correct country code so that the access point 
complies with the regulations in your country. The country 
code selection affects the wireless radio modes the access 
point can support as well as the list of channels and transmit 
power of the wireless radio.

Enabling support for IEEE 802.11d (World Mode) on the access 
point causes the access point to broadcast which country it is 
operating in as a part of its beacons and probe responses. This 
allows client stations to operate in any country without 
reconfiguration.

Disabling 802.11d prevents the country code setting from 
being broadcast in the beacons. However, this only applies to 
wireless radios configured to operate in the 

g

 band (2.4 GHz 

band). For wireless radios operating in the 

a

 band (5 GHz 

band), the access point software configures support for 
802.11h. When 802.11h is supported, the country code 
information is broadcast in the beacons. 

To enable 802.11d regulatory domain support, click Enabled.

To disable 802.11d regulatory domain support, click Disabled.

Turns the wireless radio interface on or off.

Indicates the Media Access Control (MAC) addresses for the 
interface.

This page shows the MAC addresses for Radio Interface One.

A MAC address is a permanent, unique hardware address for 
any device that represents an interface to the network. The 
MAC address is assigned by the manufacturer. You cannot 
change the MAC address. It is provided here for informational 
purposes as a unique identifier for the interface.
