Configure rates (in Mbps) for
802.11a

dot11a { disabled-rate |
mandatory-rate
|
supported-rate
} rate-value

Optional

By default, mandatory rates are 6,
12, and 24; supported rates are 9,
18, 36, 48, and 54; no rates are
disabled.

Configure rates for 802.11b

dot11b { disabled-rate |
mandatory-rate |
supported-rate } rate-value

Optional

By default, mandatory rates are 1
and 2; supported rates are 5.5 and
11; no rates are disabled.

Configure rates for 802.11g

dot11g { disabled-rate |
mandatory-rate |
supported-rate } rate-value

Optional

By default, mandatory rates are 1,
2, 5.5 and 11; supported rates are
6, 9, 12, 18, 24, 36, 48 and 54; no
rates are disabled.

Configuring 802.11n Rates

Configuration of mandatory and supported 802.11n rates is achieved by specifying the maximum

Modulation and Coding Scheme (MCS) index. The MCS data rate table shows relations between data

rates, MCS indexes, and parameters that affect data rates. A sample MCS data rate table is shown in

Table 6-1

. For the whole table, see IEEE P802.11n D2.00.
