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 affect
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
Related Commands
To view a complete list of mesh high-throughput SSID profiles and their status, use the following command:
(host) (config) #show ap mesh-ht-ssid-profile
To view the settings of a specific mesh radio profile, use the following command:
(host) (config) #show ap mesh-ht-ssid-profile <name>
Command History
This command was introduced in ArubaOS 3.4.
Command Information
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.
