Release Notes
2065 | wlan ht-ssid-profile Dell Networking W-Series ArubaOS 6.4.x| Reference Guide
Parameter Description Range Default
not responding to 802.11 packets, the AP will launch
two hardware retries; if the hardware retries are not
successful then it attempts software retries.
very-high-throughput-
enable
Enable or disable support for Very High Throughput
(802.11ac ) on the SSID.
— enabled
vht-supported-mcs-map
Modulation Coding Scheme (MCS) values or ranges
of values for spatial streams 1 through 3. Valid values
for the maximum MCS settings are 7, 8, 9 or a dash
(-) if a spatial stream is not supported. If a MCS is not
valid for a particular combination of bandwidth and
number of spatial streams, it will not be used.
7, 8, 9,
or -
Default:
9,9,9
vht-txbf-explicit-enable
Enable or disable VHT Explicit Transmit Beam-
forming for the W-AP220 Series . When this feature is
enabled, the AP requests information about the MIMO
channel and uses that information to transmit data
over multiple transmit streams using a calculated
steering matrix. The result is higher throughput due to
improved signal at the beamformee (the receiving cli-
ent). If this parameter is disabled, all other transmit
beamforming settings will not take effect.
— Enabled
vht-txbf-sounding-inter-
val
Time interval in seconds between channel inform-
ation updates between the AP and the beamformee
client. (W-AP220 Series only)
1-1000
seconds
25

Usage Guidelines
The ht-ssid profile configures the high-throughput SSID. Stations are not allowed to use HT with TKIP
standalone encryption, although TKIP can be provided in mixed-mode BSSIDs that support HT. HT is disabled
on a BSSID if the encryption mode is standalone TKIP or WEP.
You can also use this profile to configure explicit transmit beamforming for W-AP130 Series access points.
When this feature is enabled, the AP coordinates the signals sent from each antenna so the signals focus on the
receiver, improving radio range and performance. The W-AP130 Series AP can advertise transmit beamforming
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
