CoS technology includes DiffServ (Differentiated Services or DS). DiffServ is a new protocol and
defines a new DS field, which replaces the eight-bit ToS (Type of Service) field in the IP header.
Tagging and Marking
In a QoS class, you can configure whether to add or change the DSCP (DiffServ Code Point) value in
a matched packet. When the packet passes through a compatible network, the networking device,
such as a backbone switch, can provide specific treatment or service based on the tag or marker.

LABEL DESCRIPTION
Active QoS Select the check box to turn on QoS to improve your network performance.
You can give priority to traffic that the LTE Device forwards out through the WAN interface.
Give high priority to voice and video to make them run more smoothly. Similarly, give low
priority to many large file downloads so that they do not reduce the quality of other
applications.
