Guidelines
The mesh high-throughput profile defines settings unique to 802.11n-capable, high-throughput APs. If none of
the APs in your mesh deployment are 802.11n-capable APs, you do not need to configure a high-throughput SSID
profile.
If you modify a currently provisioned and running high-throughput SSID profile, your changes take effect
immediately. You do not reboot the controller or the AP.
Example
The following command configures a mesh high-throughput SSID profile named “HT1” and sets some non-
default settings for MAC protocol data unit (MPDU) aggregation:
(host) (config) #ap mesh-ht-ssid-profile HT1
max-rx-a-mpdu-size 32767
max-tx-a-mpdu-size 32767
min-mpdu-start-spacing .25
short-guard-intvl-
40Mhz
Enable or disable use of short (400ns) guard interval in 40
MHz mode.
A guard interval is a period of time between transmissions
that allows reflections from the previous data transmission
to settle before an AP transmits data again. An AP identifies
any signal content received inside this interval as unwanted
inter-symbol interference, and rejects that data.
The 802.11n standard specifies two guard intervals: 400ns
(short) and 800ns (long). Enabling a short guard interval can
decrease network overhead by reducing unnecessary idle
time on each AP. Some outdoor deployments, may, however
require a longer guard interval. If the short guard interval
does not allow enough time for reflections to settle in your
mesh deployment, inter-symbol interference values may
increase and degrade throughput.
This parameter is enabled by default.
enabled
stbc-rx-streams Controls the maximum number of spatial streams usable for
STBC reception. 0 disables STBC reception, 1 uses STBC
for MCS 0-7. Higher MCS values are not supported.
(Supported on the AP-90 series, AP-130 Series, AP-68,
AP-175 and W-AP105 only. The configured value is
adjusted based on AP capabilities.)
0-1 1
stbc-tx-streams Controls the maximum number of spatial streams usable for
STBC transmission. 0 disables STBC transmission, 1 uses
STBC for MCS 0-7. Higher MCS values are not supported.
(Supported on AP-90 series, AP-175, AP-130 Seriesand W-
AP105 only. The configured value is adjusted based on AP
capabilities.)
0-1 1
supported-mcs-set A list of Modulation Coding Scheme (MCS) values or ranges
of values to be supported on this SSID. The MCS you
choose determines the channel width (20MHz vs. 40MHz)
and the number of spatial streams used by the mesh node.
The default value is 1-15; the complete set of supported
values. To specify a smaller range of values, enter a hyphen
between the lower and upper values. To specify a series of
different values, separate each value with a comma.
Examples:
