aifsn <1-15> Configures Arbitrary Inter-Frame Space Number (AIFSN) as the wait time between data frames derived

from the AIFSN and slot time

• background – Sets the current AIFSN for low (background) traffic. The default is 7.

• best-effort – Sets the current AIFSN for normal (best-effort) traffic. The default is 3.

• video – Set the current AIFSN for video traffic. Higher-priority traffic video categories should have

lower AIFSNs than lower-priority traffic categories. This causes

lower-priority traffic to wait longer before attempting access. The default is 1.

• voice – Sets the current AIFSN for voice traffic. Higher-priority traffic voice categories should have

lower AIFSNs than lower-priority traffic categories. This causes

lower-priority traffic to wait longer before attempting access. The default is 1.

The following keyword is common to all of the above traffic types:

• <1-15> – Sets a value from 1 - 15

cw-max <0-15> Clients pick a number between 0 and the min contention window to wait before retransmission. Clients

then double their wait time on a collision, until it reaches the maximum contention window.

• background – Sets CW Max for low (background) traffic. The default is 10.

• best-effort – Sets CW Max for normal (best effort) traffic. The default is 6.

• voice – Sets CW Max for voice traffic. The default is 3.

• video – Sets CW Max for video traffic. The default is 4

The following keyword is common to all of the above traffic types:

• <0-15> – ECW: the contention window. The actual value used is (2^ECW - 1).

NOTE: Lower values are used for higher priority traffic (like video and voice) and higher values are

used for lower priority traffic (like background and best-effort).
