Command Usage
• WMM defines four access categories (ACs) – voice, video, best effort, and
background. These categories correspond to traffic priority levels and are
mapped to IEEE 802.1D priority tags. The direct mapping of the four ACs
to 802.1D priorities is specifically intended to facilitate interpretability with
other wired network QoS policies. While the four ACs are specified for
specific types of traffic, WMM allows the priority levels to be configured
to match any network-wide QoS policy. WMM also specifies a protocol
that access points can use to communicate the configured traffic priority
levels to QoS-enabled wireless clients.
• Although turning off the requirement for the sender to wait for an
acknowledgement can increases data throughput, it can also result in a
high number of errors when traffic levels are heavy.
