Parameters
wmm [background|best-effort|video|voice] [aifsn <1-15>|cw-max <0-15>|cw-min
<0-15>|
txop-limit <0-65535>]
wmm background Configures background access category wireless multimedia settings
wmm best-effort Configures best effort access category wireless multimedia settings
wmm video Configures video access category wireless multimedia settings
wmm voice Configures voice access category wireless multimedia settings
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).
