Configuring QoS on an Access PointThis chapter describes how to configure quality of service (QoS) on an access point. QoS provides preferential treatment to certain traffic at the expense of other traffic. Without QoS, the access point offers

Understanding QoS for Wireless LANs
Typically, networks operate on a
When QoS is configured on an access point, you can select specific network traffic, prioritize it, and use
Configuring QoS creates and applies policies to the VLANs configured on the access point. If VLANs are not used on the network, QoS policies can be applied to the Ethernet and radio ports.
QoS for Wireless LANs Versus QoS on Wired LANs
The QoS implementation for wireless LANs differs from QoS implementations on other Cisco devices. With QoS enabled, access points perform the following:
•Does not classify packets; it prioritizes packets based on Differentiated Services Code Point (DSCP) value, client type (such as a wireless phone), or the priority value in the 802.1q or 802.1p tag.
