Any associated clients that support the selected rates may communicate with the access point using those
rates. However, the clients are not required to be able to use this rate in order to associate. The MCS
settings determine the number of spatial streams, the modulation, the coding rate, and the data rate values
that are used.

Using the CLI to Configure 802.11n Parameters

Using the controller CLI, follow these steps to configure 802.11n parameters.
To enable 802.11n support on the network, enter this command:
Step 1
config {802.11a | 802.11b} 11nsupport {enable | disable}
To specify the modulation and coding scheme (MCS) rates at which data can be transmitted between the
Step 2
access point and the client, enter this command:
config {802.11a | 802.11b} 11nsupport mcs tx {0-15} {enable | disable}
See the descriptions of the 0 through 15 MCS data rates in the
Parameters" section on page
To use the 802.11n data rates that you configured, you need to enable WMM on the WLAN. Enter this
Step 3
command to do so:
config wlan wmm required wlan_id
The required parameter requires client devices to use WMM. Devices that do not support WMM cannot
join the WLAN.
OL-17037-01
13 (116 Mbps)
14 (130 Mbps)
15 (144 Mbps)
Click WLANs to open the WLANs page.
Click the ID number of the WLAN for which you want to configure WMM mode.
When the WLANs > Edit page appears, click the QoS tab to open the WLANs > Edit (Qos) page.
From the WMM Policy drop-down box, choose Required or Allowed to require or allow client
devices to use WMM. Devices that do not support WMM cannot join the WLAN.
Click Apply to commit your changes.
To determine if an access point supports 802.11n, look at the 11n Supported field on either the
802.11a/n (or 802.11b/g/n) Cisco APs > Configure page or the 802.11a/n (or 802.11b/g/n) AP
Interfaces > Details page.
