• Mandatory rates—The AP must support mandatory rates. Clients can only associate with the AP
when they support the mandatory rates.
• Supported rates—These are higher rates supported by the AP besides the mandatory rates.
Supported rates allow some clients that support both mandatory and supported rates to choose
higher rates when communicating with the AP.
• Multicast rates—These are rates that are supported by the AP besides the mandatory rates.
Multicast rates allow clients to send multicast traffic at the multicast rates.
When you specify the maximum MCS index, you actually specify a range. For example, if you specify
the maximum MCS index as 5 for mandatory rates, rates corresponding to MCS indexes 0 through 5 are
configured as 802.11n mandatory rates.
To configure 802.11n rates:
Step Command Remarks
129. Enter system view. system-view N/A
130. Enter RRM view. wlan rrm N/A
131. Specify the maximum MCS
index for 802.11n mandatory
rates.
dot11n mandatory maximum-mcs
index
Optional.
By default, no maximum MCS
index is specified for 802.11n
mandatory rates.
If you configure the client
dot11n-only command, you must
specify the maximum MCS index.
132. Specify the maximum MCS
index for 802.11n supported
rates.
dot11n support maximum-mcs
index
Optional.
By default, the maximum MCS
index for 802.11n supported rates
is 76.
133. Specify the MCS index for
802.11n multicast rates.
dot11n multicast-rate index
Optional.
By default, the MCS index for
802.11n multicast rates is not
specified.
Configure the same MCS index
settings for APs using 802.11n
radios in a mesh network.
