11.2 The Quality of Service General Screen
Click Configuration > Network > QoS to open the screen as shown next.
Use this screen to enable or disable QoS, set the bandwidth, and select to have
the NVG2053 automatically assign priority to upstream traffic according to the
DSCP value in the packets. See
Section 11.1 on page 131 for more information.
You can also use this screen to add, edit or delete QoS classes. A class groups
traffic into data flows according to specific criteria such as the source address,
destination address, source port number, destination port number or incoming
interface. For example, you can configure a class to select traffic from the same
protocol port (such as Telnet) to form a flow.
You can give different priorities to traffic that the NVG2053 forwards out through a
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.
