inact_auth
#iwpriv ath N inact_auth inactivity period
This sets the TSPEC inactivity period for the AP AUTH state. This is an 802.11e mechanism that allows for
allocating QoS priority to certain traffic types. The inactivity period is a timer that counts the seconds that a
QoS stream is inactive during AUTH state. This timer will delete a traffic stream after the indicated number of
seconds elapse. The default value is 180 seconds, and this command has a corresponding get command.

#iwpriv ath0 get_inact_auth

inact_init
#iwpriv ath N inact inactivity period
This sets the TSPEC inactivity period for the AP INIT state. This is an 802.11e mechanism that allows for
allocating QoS priority to certain traffic types. The inactivity period is a timer that counts the seconds that a
QoS stream is inactive during INIT state. This timer will delete a traffic stream after the indicated number of
seconds elapse. The default value is 30 seconds, and this command has a corresponding get command.

mcast_rate
#iwpriv ath N mcast_rate rate
This command is used to set multicast to a fixed rate. The rate value is specified in units of KBPS. This allows
the user to limit the impact of multicast on the overall performance of the system. The command has a
corresponding get command, and has no default value.
#iwpriv ath0 mcast_rate 10000
#iwpriv ath0 get_mcast_rate
ath0 get_mcast_rate: 10000
mode
#iwpriv ath N mode desired_mode
This command will set the current operating mode of the interface. The argument is a string that defines the
desired mode of operation. The mode will also affect the configuration of the Radio layer, so this command
should be used when modifying the operating mode of the VAP. The following is a valid list of operating
modes:
Mode Description
11B Legacy operations in the 802.11b (2.4 GHz) band
11G 802.11g
11NAHT20 802.11n A-band 20 MHz channels
11NGHT20 802.11n G-band 20 MHz channels
11NAHT40PLUS Select frequency channels higher than the primary control channel as the extension channel
11NAHT40MINUS Select frequency channels lower than the primary control channel as the extension channel
11NGHT40PLUS Select frequency channels higher than the primary control channel as the extension channel
11NGHT40MINUS Select frequency channels lower than the primary control channel as the extension channel
This command has a corresponding “get” command. The following example shows how to use the mode and
get_mode commands. The argument for mode is provided as a string. The get_mode command will return the
mode as a string value.
#iwpriv ath0 setmode 11NAHT20
# iwpriv ath0 get_mode
