There are a number of key points for the AP Developer that should be remembered in rela-
tion to the IEEE 802.11h standard:
•
802.11h only works for the 802.11a band. It is not required for 802.11b, nor 802.11g.
•
If you are operating in an 802.11h enabled domain, then the channel selection of the
BSS will always be "Auto". Even if another channel has been has been configured, this
will be ignored and auto-channel selection will occur.
•
When 802.11h is enabled, the initial bootup time will increase by a minimum of sixty
seconds. This is the minimum time required to scan the selected channel for radar
interference.
•
Setting up WDS links may be difficult when 802.11h is operational. This is because the
operating channels of the two APs on the WDS link may keep changing depending on
channel usage and radar interference. WDS will only work if both the APs operate on
the same channel. For more information on WDS, see Chapter 20: "Wireless Distribu-
tion System".

Configuring The Radio Interface
The radio interface allows you to set the radio
Table 13.3.
Note: On a two-radio AP, you must configure these radio interface settings for both Radio
Interface One and Radio Interface Two.

MAC Addresses
(Shown on two-radio
AP only)
Description
Indicates the Media Access Control () addresses for the interface.
On the two-radio AP only, the
MAC
Interface Two (Internal/Guest) are shown.
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 an interface.
