allowed to associate.
This setting has no effect on a BSS in which HT support is not
available.
max-rx-a-mpdu-
size
Controls the maximum size, in bytes, of an Aggregated-MAC
Packet Data Unit (A-MPDU) that can be received on this high-
throughput SSID.
8191/16383/32767/-

65535
8191

16383
Maximum size of 16383 bytes.
32767
Maximum size of 32767 bytes.
65535
Maximum size of 65535 bytes.
max-tx-a-mpdu-
size
Controls the maximum size, in bytes, of an A-MPDU that can be
sent on this high-throughput SSID.
1576-65535 65535
min-mpdu-start-
spacing
Minimum time between the start of adjacent MDPUs within an
aggregate MDPU in microseconds.
0/.25/.5/1/2/4/8/16 0
0
No restriction on MDPU start spacing.
.25
Minimum time of .25 µsec.
.5
Minimum time of .5 µsec.
1
Minimum time of 1 µsec.
2
Minimum time of 2 µsec.
4
Minimum time of 4 µsec.
8
Minimum time of 8 µsec.
16
Minimum time of 16 µsec.
mpdu-agg
Enables or disables MAC protocol data unit (MDPU)
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.
— enabled
no
Negates any configured parameter. — —
short-guard-
intvl-20MHz
Enables or disables use of short guard interval in 20 MHz mode
of operation.
enabled
short-guard-
intvl-40MHz
Enables or disables use of short guard interval in 40 MHz mode
of operation.
enabled
stbc-rx-streams
Controls the maximum number of spatial streams usable for
STBC reception. 0 disables STBC reception, 1 uses STBC for
0-1 1
