„Multicast rate—Data rate at which the radio sends multicast frames. The valid rates depend on the radio type and are the same as the mandatory rates. The default is Automatic, which sets the multicast rate to the highest rate that can reach all clients connected to the radio.

„Mandatory rates—Set of data transmission rates that clients are required to support in order to associate with an SSID on a MAP radio. A client must support at least one of the mandatory rates. These rates are advertised in the basic rate set of 802.11 beacons, probe responses, and reassociation response frames sent by MAP radios.

Management frames sent by MAP radios use one of the specified mandatory rates.

The valid rates depend on the radio type:

„802.11a—6.0, 9.0, 12.0, 18.0, 24.0, 36.0, 48.0, 54.0

„802.11b—1.0, 2.0, 5.5, 11.0

„802.11g—1.0, 2.0, 5.5, 6.0, 9.0, 11.0, 12.0, 18.0, 24.0, 36.0, 48.0, 54.0

The default depends on the radio type:

„802.11a—6.0, 12.0, and 24.0

„802.11b—1.0, and 2.0

„802.11g—1.0, 2.0, 5.5, and 11.0

„Supported rates—Rates that are not mandatory but that the radio can nonetheless use to send data. By default, all valid rates that are not mandatory are still supported.

„Disabled rates—Data transmission rates that MAP radios will not use to transmit data. This setting applies only to data sent by the MAP radios. The radios will still accept frames from clients at disabled data rates. By default, none of the data rates are disabled.

All rate settings apply specifically to data rates used by radios for transmission. Radios can accept frames from a wireless client at any valid rate.
