Wireless Multi-media (WMM) Settings
Router EDCA Parameters (Enhanced Distributed Channel Access) govern wireless data from your
Gateway to the client; Client EDCA Parameters govern wireless data from the client to your Gateway.
set wireless wmm option [ off | on ]
Enables or disables wireless multi-media settings option, which allows you to fine tune WiFi Multimedia
Quality of Service (QoS) by transmitting data depending on Diffserv priority settings. These priorities
are mapped into four Access Categories (AC), in increasing order of priority: Background (BK), Best
Effort (BE), Video (VI), and Voice (VO). It requires WiFi Multimedia-capable clients, usually a separate
feature enabled at the client.
❑ aifs: (Arbitration Interframe Spacing) the wait time in milliseconds for data frames.
Valid values are: 1 – 255
❑ cwmin: (Minimum Contention Window) upper limit in milliseconds of the range for determining initial
random backoff. The value you choose must be lower than cwmax.
Valid value s are: 1, 3, 7, 15, 31, 63, 127, 255, or 511.
❑ cwmax: (Maximum Contention Window) upper limit in milliseconds of the range of determining final
random backoff. The value you choose must be higher than cwmin.
Valid value s are: 3, 7, 15, 31, 63, 127, 255, 511, or 1023.
❑ txoplimit: Time interval in microseconds that clients may initiate transmissions.
Valid values are: 0 – 9999.

NOTE:
It is not recommended that you modify these settings without direct knowledge or instruc-
tions to do so. Modifying these settings inappropriately could seriously degrade network
performance.
