capabilities in beacon, probe response and association responses in the HT capabilities IE, then use the
compressed or noncompressed beamforming report from clients to form a steering matrix. The AP ensures
that the steering matrix stays current by updating and recalibrating the steering matrix at regular intervals.
By default, W-AP130 Series access points support both compressed and non-compressed steering information
from clients. If you have many clients that can send only non-compressed steering reports, best practices are
to retain the default settings, allowing the AP to support both types of steering reports. If all (or nearly all) of
the AP’s clients are capable of sending compressed steering reports, best practices are to disable non-
compressed steering in the AP’s HT SSID profile.
De-aggregation of MAC Service Data Units (A-MSDUs) is supported on W-3000 Series controllers, W-7200
Series, and the W-6000M3 with a maximum frame transmission size of 4k bytes; however, this feature is
always enabled and is not configurable. Aggregation is not currently supported.
Example
The following command configures the maximum size of a received aggregate MDPU to be 8191 bytes for the
high-throughput SSID named “htcorpnet:”
(host) (config) #wlan ht-ssid-profile htcorpnet
max-rx-a-mpdu-size 8191
