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.
