Set cwmin and cwmax on the Access Point
To set the Minimum and Maximum Contention Windows (cwmin, cwmax)
on access point-to-station traffic:
set tx-queue wlan0 with queue Queue_Name to cwmin cwmin_Value
cwmax
cwmax_Value
Where Queue_Name is the queue on the access point to which you want the
setting to apply and
cwmin_Value and cwmax_Value are the values (in
milliseconds) you want to specify for contention back-off windows.
For example, this command sets the access point Video queue (data1)
cwmin value to 15 and cwmax value to 31.
AT-WA7400# set tx-queue wlan0 with queue data1 cwmin 15 cwmax 31

Where Queue_Name is the queue on the station to which you want the
setting to apply and
cwmin_Value and cwmax_Value are the values (in
