Wi-Fi Multimedia Traffic Management
Wi-Fi Multimedia (WMM), is a Wi-Fi Alliance specification based on the IEEE 802.11e wireless Quality of Service
(QoS) standard. WMM works with 802.11a, b, g, and n physical layer standards.
WMM supports the following access categories (ACs):
l Voice
l Video
l Best effort
l Background
The following table shows the mapping of the WMM access categories to 802.1p priority values. The 802.1p priority
value is contained in a two-byte QoS control field in the WMM data frame.

WMM AC to 802.1p Priority Mapping
In a non-WMM or hybrid environment, where some clients are not WMM-capable, you can configure an SSID with
higher values for best effort and voice ACs, to allocate a higher bandwidth to clients transmitting best effort and
voice traffic.
Configuring WMM for Wireless Clients
You can configure WMM for wireless clients by using the UI or CLI.
