5. Configure the mesh high-throughput SSID parameters described in Table 136. The Mesh High-Throughput SSID
Profile configuration settings are divided into two tabs, Basic and Advanced. The Basic tab displays only those
configuration settings that often need to be adjusted to suit a specific network. The Advanced tab shows all
configuration settings, including settings that do not need frequent adjustment or should be kept at their default
values. If you change a setting on one tab then click and display the other tab without saving your configuration,
that setting reverts to its previous value.
6. Click Apply to save your settings. The profile name appears in the Mesh High-throughput SSID Profile list with
your configured settings.
Parameter Description
Basic Mesh High-Throughput SSID Profile Settings
40 MHz channel usage Enable or disable the use of 40 MHz channels. This parameter is enabled by default.
High-throughput Enable (SSID) Enable or disable high-throughput (802.11n) features on the SSID. This parameter is
enabled by default.
Advanced Mesh High-Throughput SSID Profile Settings
Temporal Diversity Enable When a client is not responding to 802.11 packets, the AP will launch two hardware
retries. If this option is enabled and hardware retries are not successful, then the AP will
launch then software retries.
BA AMSDU Enable Enable/Disable Receive AMSDU in BA negotiation.
Legacy stations Allow or disallow associations from legacy (non-HT) stations. By default, this parameter is
enabled (legacy stations are allowed).
Low-density Parity Check If enabled, the AP advertises Low-density Parity Check (LDPC) support LDPC improves
data transmission over radio channels with high levels of background noise. (For W-AP130
Series only)
Maximum number of spatial
streams usable for STBC
reception
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 W-AP90 series, W-AP130 Series, W-AP68, W-AP175 Series and W-
AP105 only. The configured value adjusts based on AP capabilities.)
Maximum number of spatial
streams usable for STBC
transmission.
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 W-AP90 series, W-AP175 Series, W-AP130 Seriesand W-AP105 only. The
configured value adjusts based on AP capabilities.)
MPDU Aggregation Enable or disable MAC protocol data unit (MPDU) aggregation.
High-throughput APs are able to send aggregated MAC protocol data units (MDPUs),
which allow an AP to receive a single block acknowledgment instead of multiple ACK
signals. This option, which is enabled by default, reduces network traffic overhead by
effectively eliminating the need to initiate a new transfer for every MPDU.
Max received A-MPDU size Maximum size of a received aggregate MPDU, in bytes. Allowed values: 8191, 16383, 32767,
65535.
Max transmitted A-MPDU size Maximum size of a transmitted aggregate MPDU, in bytes.
Range: 1576–65535
Min MPDU start spacing Minimum time between the start of adjacent MPDUs within an aggregate MPDU, in
Table 136:
