9.8 QoS Screen
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.
9.8.1 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.
