Configuring QoS

Configuring QoS
QoS is disabled by default (however, the radio interface always honors tagged 802.1P packets even when
you have not configured a QoS policy). This section describes how to configure QoS on your access
point. It contains this configuration information:

Before configuring QoS on your access point, you should be aware of this information:

Configuring QoS Using the Web-Browser Interface

This section describes configuring QoS using the web-browser interface.
For a list of Cisco IOS commands for configuring QoS using the CLI, consult the Cisco IOS Command
Reference for Cisco Aironet Access Points and Bridges.

The most important guideline in QoS deployment is to be familiar with the traffic on your wireless
LAN. If you know the applications used by wireless client devices, the applications' sensitivity to
delay, and the amount of traffic associated with the applications, you can configure QoS to improve
performance.
QoS does not create additional bandwidth for your wireless LAN; it helps control the allocation of
bandwidth. If you have plenty of bandwidth on your wireless LAN, you might not need to configure
QoS.
The ampdu command is available for the 802.11n radio interfaces. Aggregate MAC protocol data
unit (AMPDU) is a structure containing multiple MPDUs transported as a single PSDU by the
physical layer. For additional information about this command, see the Cisco IOS Command
Reference for Cisco Aironet Access Points and Bridges.
