Table 9-9 Transmit Rates
Parameter Default Value Description
mandatory • 802.11a— 6.0,12.0,24.0
• 802.11b—1.0,2.0
• 80211g—1.0,2.0,5.5,11.0
Set of data transmission rates that clients are required
to support in order to associate with an SSID on an AP
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 AP radios.
Data frames and management frames sent by AP
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
Use a comma to separate multiple rates; for example:
6.0,9.0,12.0
disabled None. All rates applicable to
the radio type are supported
by default.
Data transmission rates that AP radios will not use to
transmit data. This setting applies only to data sent by
the AP radios. The radios will still accept frames from
clients at disabled data rates.
The valid rates depend on the radio type and are the
same as the valid rates for mandatory.
If you disable a rate, you cannot use the rate as a
mandatory rate or the beacon or multicast rate. All rates
that are applicable to the radio type and that are not
disabled are supported by the radio.
beacon-rate • 802.11a—6.0
• 802.11b—2.0
• 802.11g—2.0
Data rate of beacon frames sent by AP radios. This rate
is also used for probe-response frames.
The valid rates depend on the radio type and are the
same as the valid rates for mandatory. However, you
cannot set the beacon rate to a disabled rate.
multicast-rate auto for all radio types Data rate of multicast frames sent by AP radios.
rate—Sets the multicast rate to a specific rate. The valid
rates depend on the radio type and are the same as the
valid rates for mandatory. However, you cannot set the
multicast rate to a disabled rate.
auto—Sets the multicast rate to the highest rate that
can reach all clients connected to the AP radio.
