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.

Configuring QoS
Typically, networks operate on a best-effort delivery basis, meaning that all traffic
has equal priority and an equal chance of being delivered in a timely manner.
When congestion occurs, all traffic has an equal chance of being dropped.
When you configure QoS on the access point, you can select specific network
traffic, prioritize it, and use congestion-management and congestion-avoidance
techniques to provide preferential treatment. Implementing QoS in your wireless
LAN makes network performance more predictable and bandwidth utilization
more effective.
When you configure QoS, you create QoS policies and apply the policies to the
VLANs configured on your access point. If you don't use VLANs on your
network, you can apply your QoS policies to the access point's Ethernet and radio
ports.
When you enable QoS, the access point uses Wi-Fi Multimedia (WMM) mode
