Chapter 7 Wireless LAN 7.8.3 Services Please refer to Appendix F on page 423 for more information on commonly used services. 7.9 QoS Screen Use this screen to configure QoS settings for the wireless traffic going through the ZyXEL Device. The QoS screen by default allows you to automatically give a service a priority level according to the ToS value in the IP header of the packets it sends. 7.9.1 ToS (Type of Service) and WMM QoS ToS defines the DS (Differentiated Service) field in the IP packet header. The ToS value of outgoing packets is between 0 and 255. 0 is the lowest priority. WMM QoS checks the ToS in the header of transmitted data packets. It gives the application a priority according to this number. If the ToS is not specified, then transmitted data is treated as normal or best-effort traffic. Click Network > Wireless LAN > QoS. The following screen displays. Figure 76 Wireless LAN: QoS The following table describes the fields in this screen.
