Configuring QoS

This chapter describes how to configure quality of service (QoS) on your access point. With this feature,

you can provide preferential treatment to certain traffic at the expense of others. Without QoS, the access

point offers best-effort service to each packet, regardless of the packet contents or size. It sends the

packets without any assurance of reliability, delay bounds, or throughput.

This chapter consists of these sections:

• Understanding QoS for Wireless LANs, page 9-2

• Configuring QoS, page 9-4
