The Regulatory Domain’s country code determines which channels are selected in the Valid 802.11g channel, Valid 802.11a channel, Valid 802.11g 40MHz channel pair and Valid 802.11a 40MHz channel pair fields. If none of the channels supported by the AP have received regulatory approval by the country whose country code you selected, the AP will revert to Air Monitor mode.

7.Under the Profiles list, expand the RF Managementmenu.

8.Select the 802.11a radio profileused by the AP group

NOTE: Country codes are generally specified in ISO 3166 format. To see what channels are available for a given country code, use

the show ap allowed-channels country-code <country-code> command.

Channel Switch Announcement (CSA)

When an AP changes its channel, an existing wireless clients may “time out” while waiting to receive a new beacon from the AP; the client must begin scanning to discover the new channel on which the AP is operating. If the disruption is long enough, the client may need to reassociate, reauthenticate, and re-request an IP address. Channel Switch Announcement (CSA), as defined by IEEE 802.11h, enables an AP to announce that it is switching to a new channel before it begins transmitting on that channel. This allows the clients, who support CSA, to transition to the new channel with minimal downtime.

When CSA is enabled, the AP does not change to a new channel immediately. Instead, it sends a number of beacons (the default is 4) which contain the CSA announcement before it switches to the new channel. You can configure the number of announcements sent before the change.

NOTE: Clients must support CSA in order to track the channel change without experiencing disruption.

Using the WebUI
