wmm-acknowledge-
policy
This command allows the acknowledgement wait time to be enabled or disabled
for each Access Category (AC).
Syntax
wmm-acknowledge-policy <ac_number> <ack | noack>
ac_number - Access categories. (Range: 0-3)
ack - Require the sender to wait for an acknowledgement from the receiver.
noack - Does not require the sender to wait for an acknowledgement from
the receiver.
Default
ack
Command Mode

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.
