Define both minimum Basic and optimal Supported rates as required for the 802.11b rates,
802.11g rates and 802.11n rates supported by the 2.4 GHz band and 802.11a and 802.11n rates
supported by the 5.0 GHz radio band. These are the rates wireless client traffic is supported within
this mesh point.
If supporting 802.11n, select a Supported MCS index. Set a MCS (modulation and coding
scheme) in respect to the radio’s channel width and guard interval. A MCS defines (based
on RF channel conditions) an optimal combination of 8 data rates, bonded channels,
multiple spatial streams, different guard intervals and modulation types. Clients can
associate as long as they support basic MCS (as well as non-11n basic rates).

saved configuration.
Mesh QoS Policy
Wireless Configuration
Mesh QoS provides a data traffic prioritization scheme that reduces congestion from excessive
traffic. If there is enough bandwidth for all users and applications (unlikely because excessive
bandwidth comes at a very high cost), then applying QoS has very little value. QoS provides policy
enforcement for mission-critical applications and/or users that have critical bandwidth
requirements when the wireless controller’s bandwidth is shared by different users and
applications.
