4 Wireless Configuring Quality of Service (QoS) NOTE After you configure the bandwidth utilization settings, you must click Apply to apply the changes and to save the settings. Changing some settings might cause the access point to stop and restart system processes. If this happens, wireless clients will temporarily lose connectivity. We recommend that you change access point settings when WLAN traffic is low. Configuring Quality of Service (QoS) Quality of Service (QoS) provides you with the ability to specify parameters on multiple queues for increased throughput and better performance of differentiated wireless traffic like Voice-over-IP (VoIP), other types of audio, video, and streaming media, as well as traditional IP data over the access point. Configuring QoS on the access point consists of setting parameters on existing queues for different types of wireless traffic, and effectively specifying minimum and maximum wait times (through Contention Windows) for transmission. The settings described here apply to data transmission behavior on the access point only, not to that of the client stations. AP Enhanced Distributed Channel Access (EDCA) Parameters affect traffic flowing from the access point to the client station. Station Enhanced Distributed Channel Access (EDCA) Parameters affect traffic flowing from the client station to the access point. The default values for the access point and station EDCA parameters are those suggested by the Wi-Fi Alliance in the WMM specification. In normal use these values should not need to be changed. Changing these values will affect the QoS provided. To set up queues for QoS, click the QoS tab under the Services heading and configure settings as described in Table 24. 97 Cisco AP 541N Dual-band Single-radio Access Point Quick Start Guide
