2.5.2.6.1 802.11n related
These commands provide a set of parameters and actions that can be used to configure and test various
functions specified in 802.11n and 802.11e such as aggregation, block acknowledgement, channel width
management, and static rate settings.
addba
delba
#iwpriv ath N addba AID AC BufSize
#iwpriv athN delba AID AC initiator reason
These test commands are used to manually add or delete Block Acknowledge Aggregation streams. Note that
automatic addba/delba processing must be turned off prior to using these commands (see
setaddbaoper
). Both
commands require the AID (association ID) and the AC specified. The Association ID is the value shown when
using the
wlanconfig list command. When adding an aggregation link with addba, the BufSize parameter must
be set to the maximum number of subframes that will be sent in an aggregate. When deleting an aggregation
link, the initiator field indicates whether this link was initiated by the AP (1) or the remote station (0). The
reason code is an 8-bit value indicating the reason the link was shut down. These commands have no
corresponding get commands, nor do they have default values.
#iwpriv ath0 addba 1 0 32
#iwpriv ath0 delba 1 0 1 36
addbaresp
#iwpriv ath N addbaresp AID AC status
This command will send an addba response frame on the indicated association ID (AID) and AC. The
Association ID is the value shown under the AID column when using the
wlanconfig list command. The status
value is an 8 bit value indicating the status field of the response. This is normally used only during testing of
the aggregation interface. The command does not have a corresponding get command, nor does it have a
default value.
#iwpriv ath0 addbaresp 1 0 25
ampdu
#iwpriv ath N ampdu 1|0
This is the same command as used in the Radio layer. This command will affect ALL VAPs that are attached to
the same radio. The command is used to enable/disable transmit AMPDU aggregation for the entire interface.
Receiving of aggregate frames will still be performed, but no aggregate frames will be transmitted if this is
disabled. This has a corresponding get command, and the default value is 1 (Enabled).
#iwpriv ath0 ampdu 1
#iwpriv ath0 get_ampdu
ath0 get_ampdu:1
ampdulimit
#iwpriv ath N ampdulimit Byte Limit
This is the same command as used in the Radio layer; it affects ALL VAPs that are attached to the same radio.
This parameter limits the number of bytes included in an AMPDU aggregate frame. Frames add to an
aggregate until either the transmit duration is exceeded, the number of subframes is exceeded, the maximum
number of bytes is exceeded, or the corresponding queue is empty. The subframe causing excess conditions is
not included in the aggregate frame, but queues up to be transmitted with the next aggregate frame. The default
value of this parameter is 50000. This command has a corresponding get command.
#iwpriv ath0 ampdulimit 48000
#iwpriv ath0 get_ampdulimit
